Game Updates

Han · December 5, 2018

Dear friends,

We spent the two weeks since the previous release on intensive work on important aspects of the project. In the not-too-distant future, we'll be adding some huge new features for our Early Access titles, so we've decided to take some time and concentrate on several smaller, but important and long-awaited improvements and create this update.

The main feature of this release is revised airframe damage modeling - an important part of the damage system. Airframe damage system was completely overhauled to take into account additional parameters. The damage modeling as a whole was tuned and improved and bugs fixed - you can read the entire list below.

There is large amount of changes and improvements in aircraft systems, their model and the AI. We added the new British pilot model to the sim and all Bodenplatte and Flying Circus pilots can now take their oxygen masks and goggles on and off. Multiplayer improvements also continue since the last version too. There are new performance optimizations for sea maps. Users who encountered stutters using Microsoft Force Feedback joysticks and TrackIR now have an option to tune FFB effect polling frequency using the additional setting in startup.cfg file.

For mission designers we added a way to control Timer and Counter values dynamically. To do this, there are two new logical objects Modifier: Add Val and Modifier: Set Val. We plan to widely use them to alter various triggers in the future, but at the moment they can be used for:
- modifying a Timer trigger value. A modifier can set, add or substract the time value in a timer by using the 0 index of the controllable value and 1-st field of the value vector. When set to a negative value, the time counter is reset and the timer stops until the next input. For example, this can be used to reset and stop a timer in a mission, delaying some events tied to it.
- modifying a Counter trigger value and threshold (initiall set in a mission). To alter a Counter value, use the 0 index of the controllable value or alter Counter threshold using the 1-st index. For example, a certain mission event like a premature elimination of some targets can lower the threshold of a Counter to make sure the others are eliminated at the moment the player arrives to the waypoint.

Main features:
1. Late war British pilot added to Spitfire Mk.IXe;
2. New control elements added to mission logic (useful for mission designers): "Modifier: Add Val" and "Modifier: Set Val". They can alter the values of other logical elements - Counter and Timer (when used with a Timer object, Set Val can input a negative value to reset and stop a Timer);
3. Force Feedback joystick owners who experience stutters can alter the new value in startup.cfg that governs the maximum frequency of FFB effects polling to try to eliminate them (update_freq parameter in [KEY = force_feedback] section can be set to a value from 0.5 Hz to 10 Hz, example: update_freq = 10.0);
4. Additional renderer optimizations for sea maps (Kuban, Bodenplatte in the future) allowed to boost performance on such maps even more;
5. AA searchlights now can follow Attack Area command which can be used to limit their search area and/or use them as visible beacons (useful for mission designers);
6. Multiplayer: 'allow other players to man stations' option now saved;
7. Multiplayer: various issues like statistics 'freezing', inability to start a mission, kill messages disappearing were fixed for high-load servers;
8. Multiplayer: missing AP hit sound effects and some other sounds restored;
9. A rare crash that could happen in high load situations like joint air-ground engagements with many units has been fixed;
10. keep_binary_log = 0 option in startup.cfg correctly removes binary logs from the game folder on exit;
11. Career: mission area correctly set while escorting transport planes in Stalingrad TOW;
12. Incorrect navigational markers won't be shown in a mission without player aircraft;

Update 3.011

Dear pilots,

Today is an important day. First, we just released two new WWI fighters for all Flying Circus: Volume I customers - Fokker D.VII and Sopwith Dolphin. They are 5th and 6th aircraft released for it, so along with the map of Arras being actively developed, we can say that Flying Circus project is progressing nicely and more than half of it is already completed.

Second, our Tank Crew project finally includes visible crew for two already released tanks. Since we'll be releasing four new tanks and Prokhorovka map really soon, this project is also maturing at a good pace.

Of course, we also prepared a list of many other improvements for you:

1. Fokker D.VII is available to Flying Circus: Volume I customers;
2. Sopwith Dolphin is available to Flying Circus: Volume I customers;
3. KV-1s and Pz-VI-H1 tanks (Tank Crew project) now have visible crews;
4. AI pilots correctly attack landed or taking off enemy planes;
5. Artillery markers on the map were updated;
6. Simple (not player controllable) vehicles now have more detailed armor. This is noticeable while attacking them from above;
7. Projectile ricochet modeling became more complex;
8. Wandering personnel on the ground won't die from collisions that easy;
9. The pathfinding of vehicle columns travelling through settlements has 25% less performance impact;
10. Simple vehicles adjust their speed accordingly to the surface type (road or cross-country);
11. There are new AI vehicle formations available - line left, line right, centered line - and ability to make naval-like all-together turn;
12. The ground AIs keep formation better;
13. Multiplayer: now at least 25% of the affecting player coalition or 25% of all players on the server must vote to ban a player;
14. Multiplayer: visible tank ammo won't visually 'shake';
15. Multiplayer: when other players occupy aircraft turrets, their remaining magazines and individual rounds are displayed correctly;
16. Multiplayer: net traffic for multi-crew aircraft has been optimized;

Update 3.012

Dear friends,

We just released the new update 3.012. Only two weeks have passed since the previous update so the changelist isn't that long, but this time our customers will get FIVE new pieces of content for all three our current projects at once.

First, this is a new Collector's Plane for Bodenplatte - Fw 190 D-9 "Dora", one of the legendary late war Luftwaffe planes with very good speed and armament. Its main difference compared to previous models is Jumo-213 A1 water cooled engine equipped with MW 50 water-methanol injection system that can be used to increase the power output even more for up to 10 minutes. Another improvement of this plane is the automatic engine governor MBG and an effective engine cooling. This is also the first aircraft in our project to receive EZ 42 gyro gunsight. "Dora" could carry up to 500 kg bombs and R4M Orkan rockets (the new weapon in our project as well) which later served as a base for many post-war unguided rocket designs.

Second, we released the Prokhorovka map for Tank Crew - Clash at Prokhorovka project. This map is an important step in our map technologies because the polygonal net of the landscape is 16 times more detailed than on previous maps. In addition, the detailed zone for ground warfare (20 km to the South and the West of Prokhorovka) contains new high detailed buildings with new damage visualization. It should be noted that this more detailed environment, of course, demands more from the graphics subsystem, but reasonable graphics settings can give you good performance even on middle range video cards. You may ask "Why don't you make all the new maps at this level of detail?", but the answer is that increasing the level of detail reduces the overall size of the map. A good map for the joint tank and air battles (100 x 100 km in case of Prokhorovka) would be not enough for a full-blown, 'air campaign' map that should be 200 x 250 km minimum. Therefore, Prokhorovka map is a fine balance of several things. It allows making interesting tank campaigns, having interesting joint tank and aircraft multiplayer, keeping the performance impact 30% or less at reasonable graphics settings, and having improved visual quality at the ground level required for the ground battles.

Third, Tank Crew - Clash at Prokhorovka customers get two new toys: M4A2 and PzKpfw.III Ausf.M. Both tanks were interesting machines and they are recreated painstakingly and with passion. It should be noted that M4A2 could stand its own even against the heavier German adversaries thanks to its maneuverability, good turret traverse speed and sufficient armor penetration ability of its solid AP round. The medium tank PzKpfw.III Ausf.M also had a good chance against medium Soviet tanks - APCR rounds could penetrate their armor while its frontal protection was relatively good thanks to the spaced 50 and 20 mm armor plates. It also had a low visible profile, good maneuverability and high rate of fire.

Fourth, Flying Circus customers get Fokker D.VIIF. it was one of the best, if not the best, Deutsche Luftstreitkräfte fighter of WWI. The new and powerful for its time BMW IIIa engine gave the plane high speed and maneuverability at high altitudes while the oxygen supply enabled a pilot to fight up there effectively. Its armament is standard for German fighters of that time - two 7.92 mm LMG 08/15 "Spandau" (650 rounds per minute each).

1. Fw 190 D-9 "Dora" fighter is available to Battle of Bodenplatte Premium Edition owners;
2. Prokhorovka map (Southern part of the Kursk salient) is available to Tank Crew - Clash at Prokhorovka owners;
3. M4A2 tank is available to Tank Crew - Clash at Prokhorovka owners;
4. PzKpfw.III Ausf.M tank is available to Tank Crew - Clash at Prokhorovka owners;
5. Fokker D.VIIF fighter is available to Flying Circus - Volume I owners;

6. UDP output API for moving platform simulators was added, details are in attached document;

Il2_MotionOutput.zip
7. Locomotive tenders are destroyable once again;
8. The oxygen system capacity corrected (increased) on Fokker D.VII;
9. The sound of a damaged engine made more pronounced on all aircraft;
10. KV-1s, Pz.VI-H1, M4A2, and Pz.III-M have night gunsight illumination;
11. KV-1s and Pz.VI-H1 turrets bend their antennas when rotating;
12. Rocket exhaust flame corrected - it cuts immediately when the engine of a rocket stops and its smoke trail disappears faster;
13. A game freeze (when a statistics screen was visible on top of the other menus) has been fixed.

PS:

Information for mission designers and server hosters:

'Block' objects durability has been changed.

Smaller objects like static vehicles (static_...) should have Durability = 500

Medium sized objects (static fighters, small control tower, etc.) should have Durability = 1000

Big objects (like static bombers) should have Durability = 1500

Please discuss the update in this thread.

Update 3.101

Dear friends,

Today we have finished another huge update and it is already available to you. It includes the new war machines you can control - jet fighter/bomber Me 262 A Schwalbe for Bodenplatte, Т-34-76 made by UVZ factory in early 1943 for Tank Crew - Clash at Prokhorovka and airplanes S.E.5a and Albatros D.Va for Flying Circus - Volume I.

Upping the exterior textures to 4К quality level for Bf 109 F-4 and Fw 190 A-8 are another neat feature, as well as adding visible crews to player controllable Pz.III Ausf.M and M4A2. All VR users get the long-awaited fix of an aircraft propeller that looked distorted with VR reprojection turned on. There are many changes in aircraft and ground AI. The level of detail of player controllable tank systems and their damage model is nearly final. And as usual, there are many improvements in FM and aircraft systems modeling.

The notable difference was found at lower flight speeds, but additional research showed that this error made during porting of RoF planes to Flying Circus more or less affected all flight characteristics of the Flying Circus aircraft. In this update this error is fixed, so flight characteristics of all Flying Circus planes fully correspond to RoF before update 1.034. You can see the updated flight characteristics of Albatros D.Va and S.E.5a in their in-game descriptions, while updated descriptions for other Flying Circus aircraft will follow in the next update when we redo all the required measurements;

71. All aircraft: wind noise sound with jettisoned or broken canopy won't disappear at 720 kph and higher speeds;
72. All aircraft: new technochat message informs the player about the engine failure (when it shuts off by itself without player or throttle limiter input);
73. All aircraft: new technochat message informs the player that the engine start command is ignored if the startup requirements are not met;
74. Fw-190 D9 and Me 262 A: there is a tip in chat clarifying that the engine throttle is blocked from moving to cutoff position when the engine is on;
75. Sopwith Camel and Sopwith Dolphin skid steering animations were corrected;
76. Weight values listed for all large gunsights of Flying Circus planes and for the camera on SPAD XIII.C1 have been corrected;
77. Weight values listed for additional Lewis MGs on Sopwith Dolphin have been corrected, speed loss information added;
78. Moving horizontal stabilizers control levers or wheels can be heard;
79. When an engine is turned off, the motion speed of a throttle lever with engine helpers turned on has been increased (it is now the same as its motion speed with engine helpers turned off);
80. In multiplayer, you can hear the engine starter of another player.

Because of the huge amount of changes, the track and mission format was changed. If you're an author of a custom mission or campaign, you need to resave your creation (it can be done quickly using 'Convert missions to binary in folder' in the Mission editor).

Update 3.102

Dear friends,

We're glad to report that the new update containing three new war machines are out. The first one of them is Pz.Kpfw. IV Ausf.G German medium tank for Tank Crew - Clash at Prokhorovka project. It was one of the most commonly used German tanks and had an interesting mix of powerful weaponry and lacking armor, making its use in the sim somewhat peculiar. It also had an interesting feature - autonomous turret traverse mechanism powered by a dedicated petrol motor.

The second one is the WWI RAF fighter bomber Bristol Fighter F.2B for Flying Circus - Volume 1 project. This airplane had good flight characteristics among the two-seaters, various armament and could perform a wide selection of tasks. Two modifications of this aircraft are included - with Falcon II and Falcon III engines.

And the third one is another Flying Circus - Volume 1 aircraft - German WWI ground attack plane Halberstadt CL.II. This multifunctional machine had good defensive turret equipped with one or two Parabellum LMG 14 machine guns fed by large-capacity magazines. Halberstadt could have one or two forward-firing MGs and carry 12 kg and 50 kg bombs, camera for aerial recon and radio for aerial spotting.

In addition to them, the update includes exterior textures in 4K quality for Bf 109 G-14 and Fw 190 A-3. There are also several important improvements in the full list of changes:

1. PzKpfw.IV Ausf.G is available to Tank Crew - Clash at Prokhorovka owners;
2. Halberstadt CL.II (Mercedes D.IIIa (180 h.p.) and Mercedes D.IIIau (200 h.p.) modifications) is available to Flying Circus - volume 1 owners;
3. Bristol Fighter F2.B (Falcon II (255 h.p.) и Falcon III (285 h.p.) modifications) is available to Flying Circus - volume 1 owners;
4. Bf 109 G-14 has 4K exterior texturing made by Martin =ICDP= Catney;
5. Fw 190 A-3 has 4K exterior texturing made by Martin =ICDP= Catney;
6. User interface checkbox that disallows other players to occupy one of the stations of your tank in multiplayer works now;
7. Main tank gunfire sound won't be skipped while shooting at a maximum rate of fire;
8. Tank traverse systems on player controllable tanks can be damaged now;
9. Switching between main and backup gunsights on player controllable tanks happens correctly;
10. Chalk slopes on the Prokhorovka map won't visibly appear and disappear;
11. Forests on the Prokhorovka map won't visibly blink;
12. Looking at an aircraft mirror at certain view angles won't cause a severe performance drop that was noticeable at high visibility distance settings on low- and middle-end video cards;
13. Destroyed ground vehicles on the GUI map are semi-transparent;
14. Engine throttle control helper logic has been updated (previously it could limit the available engine power at high altitudes);
15. S.E.5, Sopwith Camel and Sopwith Dolphin ailerons buffeting amplitudes at higher flight speeds have been corrected.

Please discuss the update in this thread.

Update 4.001

IL-2: Great Battles Version 4.001 Launched – Battle of Bodenplatte and Flying Circus Officially Released! Tank Crew Campaigns - Released!

Dear Pilots!

Finally, we have reached a very important milestone for our latest IL-2 Sturmovik titles. Today, two projects moving from the Early Access phase to Official Release. The first of these is Battle of Bodenplatte, which acquired the last major content components that were missing - the seasonal textures for the Rhineland map and the Pilot's Career. However, this does not mean that work on this project is completely done, we plan to spend some time before we begin our next project on fine-tuning and polishing a number of its components and adding a couple yet to be completed pieces such as Air Marshal. However, we feel it contains enough content and features that we can begin to sell it in all our channels including Steam as we head into the Holiday Season. In addition, we plan to closely monitor your messages in order to improve the quality of the project as much as we can in the last part of 2019. Bodenplatte turned out to be a truly record-setting job for us, the volume of work done on the development of maps and aircraft of the late period of the war is unprecedented for us. The late period imposes serious additional requirements on the manufactured equipment; however, the result is extremely interesting. The included aircraft make an incredible impression, because this is already the "apogee" of piston powered planes and, at the same time, the "dawn" of jet aircraft. The Rhineland map impresses with its scale, size and richness of cities and the number and historically researched airfields. The career "Battle of the Rhine" takes place over a fairly long period of time that includes four seasons - from September 17th, 1944 to April 1st, 1945. The Career covers a very significant part of the war on the western front - more than half a year. Battle of Bodenplatte was a bold step for us and when coupled with our other two projects, it pushed us to our creative limits. We hope you will enjoy it! Also, a Standard Edition of BOBP will be coming soon with the P-38J and Fw-190 D-9 offered as Collector Planes to give users more buying options. BOBP will also be available on Steam in the coming weeks, there are still a few details we must work out there first.

Flying Circus - Volume 1 is now available in its fully planned state and all the remaining ground-based equipment of the First World War have been added in our new standard of visual quality. Observation balloons with observers who may leap from their post when under attack are also included now. A number of improvements were also made on the map, primarily to the front line. We hope that users who purchase this project will like the step forward in comparison with our previous title Rise of Flight, especially in the visual quality of aircraft and the environment that we, together with our partner Yugra Media, have created for you. Although the flight models generally correspond to the ones from Rise of Flight, many of the improvements that have been made over the past 7 years for Il-2 Sturmovik play a role in Flying Circus as well. Such improvements automatically benefit all projects within the framework of our one common game world and give a new, previously unavailable experience of virtual flight and combat in the First World War. All these new opportunities unfold in their fullest when playing with the use of virtual reality devices. FC includes so many new things - new landscape technology, new lighting and clouds, better sound, new AI and improved ballistics, new graphic effects and new materials for aircraft surfaces, new detailing of textures and models - all this and much more gives the virtual pilots of the First World War something that is not available anywhere else. We hope to make more Flying Circus volumes in the future and we thank those who have jumped into this new product so far!

Note: We have extended the $10 Off Early Access discount for days more, but it will go to full MSRP very soon. Make your purchase before the price goes up!

Tank Crew – Clash at Prokhorovka is still under development, as one more tank and three self-propelled guns are being built by our DigitalForms partners. However, from the point of view of the gameplay, this project has almost reached its planned goals - this is expressed in the release of the Breakpoint and Last Chance scenario campaigns in this version. These campaigns tell the story, in the maximum possible historical manner we can, about the complex and intricate events of one of the greatest tank battles on the Eastern Front - the battle of Prokhorovka.

This battle was not limited only to the events of July 12th, it took place over several tense days, from July 6th to July 16th, 1943. The events and outcomes of this battle are extremely complex and controversial. Although the Soviet troops and armored forces suffered heavy losses, the German command was never able to achieve their planned goals. At the end of the battle, the situation in this sector of the war front almost returned to what it was before it began. However, numbers or the “net book balance” does not always determine the magnitude of the event. The incredible tension, power, complexity and intensity of this military clash, which practically merged into one single and continuous epic multi-day battle, has few equals in world history. And the ambiguity of the outcome of the battle only enhances the intensity of the drama of these events, which do not require any embellishment - simply being retold "as is", without exaggeration is incredibly exciting. It should also be noted that the release of these tank campaigns is accompanied by the completion of the development of some of the most important features of Tank Crew – the radio and command interface. This will allow you to better control your own tank and your tank platoon. We also plan to continue the refinement of our tank project in the coming months as this project too readies for official release.

And finally, the Achtung Spitfire! Scripted Campaign is also now released and ready to be played! Developed by our friends The Syndicate, this historically inspired campaign contains 20 missions featuring a fictional storyline that is inspired by historical events. Your character is a young Russian pilot from Siberia serving on the North Caucasus Front in late May 1943. The campaign features missions inspired by the Soviet 37th and 56th Armies attack on the German 44th Army Corps west of the city of Krymskaya. You’ll fly a bird of a different feather in the lend-lease Spitfire Mk.Vb over the beautiful Kuban region of the Soviet Union. The campaign is great fun and full of action.

This campaign also has a new feature. We have added support for special assigned skins for the player’s plane and other planes I the mission. This is a first for us in a pay-ware campaign such as this. However, to see them, you must download the free skin pack from HERE and place the skins in the Spitfire Mk.Vb Skins folder. We have decided to offer the skin pack as an optional download to lighten our distribution costs and the size of your install if you don’t own this campaign. The skin pack is offered free of charge of course.

We thank you for your patience as we have readied this product for release and many of you have already pre-ordered it and we appreciate your support. Products like these add more diversity to our product line and help fund many new innovations and content for all of you.

And now we proudly present version 4.001 to you, our friends, partners and customers. And like most huge updates, there are likely to be some bugs or other unintended issues missed in testing. We of course, as always, will address them just as fast as we can. We appreciate your support as we have worked hard to build all of these new products. Here’s to you and to more great combat-sim goodness in the future!

Update 4.002

Dear Friends,

Our team is glad to announce that we finished another update 4.002. In this version, all Tank Crew owners get the SU-122 assault gun. In addition, everyone gets many improvements - some of them our community asked for a long time. After additional work on the aircraft visibility modeling against the clouds is improved. We also added automatic dive-recovery controls to four bombers from Battle of Stalingrad and Battle of Moscow. The login time has been drastically decreased, it will now happen up to ten times faster than before. Tank and aircraft turrets aiming will be more convenient and there are many other minor improvements. Let's go into detail about the automatic dive-recovery controls:

Ju-87
When the dive system is engaged, the plane enters a dive when the air brakes are extended and will recover from the dive either by pressing the bomb drop button or when the air brakes are retracted. The dive system controls are separate: the trimmer tab on the right elevator is controlled by the dive system while the pilot controls the trimmer tab on the left elevator. Therefore the pilot input and dive system input of the trimmers are independent, and when the dive system is in operation, there is no indication of a trimmer position change in the technochat.

Ju-88
When the dive system is engaged, the plane enters a dive when the air brakes are extended or when the dive button (LCtrl + D by default) is pressed. The plane will recover from the dive either by pressing the bomb drop button or by pressing the dive button (LCtrl + D by default). The dive system will return to the neutral position of the elevator trim, while the full range of trimmer travel from the pilot’s input is preserved. Therefore the pilot input and dive system input of the trimmers are independent, and when the dive system is in operation, there is no indication of a trimmer position change in the technochat. Also, the elevator trim is automatically shifted when the stabilizer is moved to the landing position (when flaps are released to the landing position). This also shifts the trim back to the neutral position.

Pe-2 (both series)
When the dive system is engaged, the plane enters a dive when the air brakes are extended (pass through the 45° position) and will recover from the dive when you press the bomb drop button or the dive recovery button to exit the dive (LCtrl + D by default). The dive system controls the elevator trim -for correct operation, the trimmer must be in the range between -4.5 ° to + 4.5 ° before turning on the dive system. If the trimmer is outside this range or if the airplane is trimmed manually while the dive system is in operation or if the air brakes are retracted the dive system will disengage.

Ju-87 and Ju-88
Contact altimeters are installed on these aircraft. The RShift + K and RCtrl + K commands (by default) set the bomb release (contact) altitude. When the dive system is engaged, the buzzer will sound 250 m above the contact altitude. Buzzer turns off when the contact altitude is reached or when the dive system is disengaged. The pressure setting is adjusted by the same command as on the main altimeter (with a short pause after setting the pressure on the main altimeter). The contact altimeter is not connected with the dive system, it is a separate device that just gives an audio signal at a contact height.

Main features
1. SU-122 assault gun made by Ural heavy machinery factory in 1943 is now available for all Tank Crew owners;

Update 4.005

Dear friends,

The IL-2 Sturmovik team is happy to announce that another, very big and important milestone in the evolution of our project has been reached and its result is ready to be downloaded to your PCs. This time the update doesn't bring new content since the development of the new Normandy project is at the very early stage. However, it contains an enormous block of changes paramount for the IL-2 as a combat flight-sim, namely the aircraft damage model and munitions damage calculations. Earlier we have published several Dev Blogs dedicated to these changes, where they are covered in detail and how they affect the gameplay.

Additionally, the external textures of four previously released aircraft are now available in 4K quality thanks to Martin =ICDP= Catney and Francisco =BlackHellHound1= Bindraban. 4 additional ground vehicles were added to the sim - two ambulances and two fuel trucks. And a new language has been added to the game - Simplified Chinese! Well, at least most of the sim is translated, some parts will have to wait. More on that below.

But of course, this is not quite all we have done. The change-list contains a whopping 140 changes - this is the all-time record for our project! There are numerous improvements to the aircraft simulation, aircraft models, player controlled tanks (Tank Crew) and artificial intelligence (AI). The causes of several important issues we weren't able to reproduce previously due to their rarity and randomness and thus fix before were finally found and fixed. The full list contains many other improvements and fixes as well. Take a look:

Main features

1. MiG-3 series 24 exterior textures, including damage, are in 4K quality now thanks to Martin =ICDP= Catney;

2. Pe-2 series 35 exterior textures, including damage, are in 4K quality now thanks to Martin =ICDP= Catney;

3. Pe-2 series 87 exterior textures, including damage, are in 4K quality now thanks to Martin =ICDP= Catney;

4. Bf 109 G-4 exterior textures, including damage, are in 4K quality now thanks to Francisco =BlackHellHound1= Bindraban;

5. Binoculars have been added for tank commanders (press LCtrl + 5);

6. GAZ-55 ambulance vehicle added;

7. BZ-35 fuel truck added;

8. Opel Blitz ambulance vehicle added;

9. Opel Blitz Tankwagen fuel truck added;

10. New language added - Chinese Simplified (简体中文). The career mode is not yet completely translated since the newspaper articles and some squadron histories and award descriptions are in English (they are not necessary for playing though). The Chinese symbols in the pilot name won’t work sadly due to the technical limitations in the mission file format.

Aircraft Damage Model Improvements

11. All aircraft got the new, significantly more advanced version of the airframe damage calculations: each aircraft has its own geometrical sizes of the airframe parts and the material types while the damage calculations take into account the peculiarities of the AP, blast and fragmentation damage;

12. A complete rework of aircraft skin damage calculations has been done and it now takes into account the projectile caliber or its HE capability: now AP ammo and bullets damage the aircraft skin to much lesser extent than HE ammo while ramming an aircraft with a propeller of another instantly causes severe aircraft skin damage;

13. Visual hit effects (sparks, splinters, etc.) and sound effects now depend on the material of a hit part of the aircraft;

14. A one projectile impact won’t erroneously cause multiple (doubling) damage effects on the airframe parts which have several hitboxes;

15. Projectile impacts (and ramming an aircraft with a propeller of another) at the parts which don’t have their own cracks modeled in 3D visual model (for instance, when shooting at a wing root that should cause a crack in the wing on the aircraft where a crack at the wing base is not modeled) are calculated in more detail;

16. Projectile impacts (and ramming an aircraft with a propeller of another) at the parts not connected to the airframe won’t damage the airframe (for example, hitting an engine nacelle of a twin-engine aircraft won’t destroy a wing);

17. The calculations of the energy impulse transfer to an aircraft from a munition it was hit by now take into account the shots that went through it;

18. Exploding shells no longer damage the airframe by their initial kinetic energy of an intact shell, only by the blast and the kinetic energy of its fragments;

19. The following visual effects of the aircraft fragments were corrected (turned on when needed and off when not needed): landing gear dust (in the flight), the lighting from landing and navigation lights, guns firing and engine exhausts, smoke from smoke generators and vortex trails from the wingtips);

20. The found discrepancies between a new and repaired aircraft aerodynamics have been fixed;

21. A rare issue that could cause the airframe cracks to preserve after repairing has been found and fixed;

22. The modeling of the combat damage of the piston engine crank gear became more detailed and takes into account the engine type (for instance, the damage of the crank gear of the air-cooled engines happens more rarely than crank gear of the liquid-cooled engines) and the peculiarities of the armor penetration, blast and fragmentation effects of the munitions. The damage of the crank gear can cause the wedging up and seizing up of the crankshaft while the heavy momentary incurred damage can cause the immediate stop of the crankshaft;

23. It is now possible to damage one or several engine cylinders at once by weapons fire, reducing its power output. Damaged pistons can affect the crank gear and can be accompanied by oil and coolant leaks. The calculations of the incurred damage and leakage values take into account the type of the engine and the peculiarities of the armor penetration, blast and fragmentation effects of the munitions;

24. The calculations of an engine fire probability from torn fuel lines and oil leaks take into account the peculiarities of the armor penetration, blast and fragmentation effects of the munitions;

25. The physical model of the engine now differentiates the two types of oil leaks: from the engine and from the oil system;

26. Only the actual oil leak from the engine now soils up the canopy instead of a general engine damage;

27. An excessive amount of piston engine shaking caused by the crank gear damage has been reduced;

28. The calculations of an oil tank or oil radiator leak probability, its size and leakage value take into account the peculiarities of the armor penetration and fragmentation effects of the munitions in detail;

29. The calculations of a coolant tank or water radiator leak probability, its size and leakage value take into account the peculiarities of the armor penetration and fragmentation effects of the munitions in detail;

30. The calculations of a fuel tank leak probability, its size and leakage value take into account the peculiarities of the armor penetration and fragmentation effects of the munitions in detail. The fuel tanks leak protection will be taken into account later, when the next level fuel system modeling is finished;

31. The visual intensity of a fuel, oil, and coolant leaks now corresponds to the actual severity of a leak closer;

32. When calculating the probabilities of a fuel tank fire and explosion, the different AP, blast and fragments effects are taken into account as well as the amount of the fuel leaking from the tank at the moment. Inert-gas pressurization and other fire countermeasures will be taken into account later when the next level fuel system modeling is finished;

33. Bf 110 G-2, Bf 110 E-2 and Hs-129 B-2 right engines won’t be excessively damaged by explosion fragments;

39. The landing gear doors on all aircraft are destroyed if landing gear wheels are torn off in retracted position;

40. Hs 129 B-2: the destruction of the right landing gear door won’t generate the landing gear door debris on the left;

41. Bf-109 (all series except E7): the loss of the vertical stabilizer and the central part of the horizontal stabilizer is temporarily blocked due to the interdependence of this damage in the 3D model, which makes this point extremely vulnerable to combat damage and causes undesirable results. We will try to move the breaking point above the stabilizer in the future and fix this limitation. Damage to the rudder, elevators and horizontal stabs are still possible and the rudder and elevators can still be detached. And the left and right portions of the horizontal stab can also be lost;
42. Bf-109 (all series): the mixed up locations where the debris of the landing gear bay doors appear have been corrected;

43. MiG-3 series 24: the main landing gear bay doors in the wing can also be torn off by an excessive ram air pressure;

44. Excessive rear hemisphere protection of the Pe-2 gunners from the fragments has been corrected;

45. Ju-52/3m g4e: the oil level gauges display the correct amount of the oil left even if it is completely gone or after the oil system repair;

46. Ju-52/3m g4e: first pilot bailing out won’t cause the death of the second pilot and the gunner;

General Damage Model Improvements (for all objects in the sim)

47. A complete overhaul of the blast and fragmentation damage, as well as armor penetration damage has been finished, including, but not limited to: correction of calculation errors, calculation speed optimizations, protection of the calculation results for finding possible errors in the initial data;

48. Insufficient blast damage in case of a very near explosion or inner explosion has been corrected;

49. The number of fragments hitting an object is correctly calculated basing on the distance to an explosion, including the case of inner explosion;

50. Now there is a possibility of a ‘stray fragment’ impact when the expectation function gives less than one fragment due to the distance to the explosion (outside the kill area), which is important in a case of multiple explosions;

51. The armor penetration ability and damage of projectile increases if the resulting impact velocity exceeds the muzzle velocity of a projectile in the reference test data;

52. The fragmentation damage modeling is made less abstract for all ammunition types: the formation of the fragments, their initial speeds, masses and sizes are calculated and their loss of velocity with the distance traveled is calculated using the modern estimates of their resistance factor and the integration of their movements;

53. The calculations of the penetration ability of the combined HE and frag damage is also less abstract. Instead of using an empirical parameter, the system now uses the speed, mass, and size of a fragment to model a penetration and the massed impact in case of a near explosion is also modeled;

54. Since the calculations of the penetration ability and the energy of fragments were changed, the excessive effectiveness of the bombs against armored targets at large distances has been reduced, but a very close explosion is much more effective than before;

55. The penetration ability of the fragments created by shells containing a small amount of explosives relative to their overall mass was also reduced because of the same reason;

56. The blast damage calculations use a more accurate power law depending on the distance to the blast center. The damage inflicted by a blast and its ability to break through an armor sheet now drops as the distance increases faster than before, but became much more powerful at very short distances;

57. Engines, drivetrains, reduction gearboxes, ammo racks and other large pieces of equipment now have their own hard casings modeled where applicable and they can protect them from some damage;

58. In a rare case of a direct bomb hit at a turret of a flying aircraft, aerostat or a parachute there won’t be a detonation delay that could cause it to explode at a distance to the object;

59. The severity of a wound depends on the impact area: a head hit is more critical than a body one while a body hit is less severe than it was before;

60. The crew members experience less pain shock from wounds and impacts;

Player controllable tanks improvements

61. The death of a radio operator now blocks the external communications;

62. Pz.III-L and T-34 STZ tanks ammo racks now are damageable;

75. The casing of the various large systems (engine, gearbox, ammunition) can protect them from shell fragments;

76. An additional armor sheet on the front hull of the KV-1s is now modeled;

AI Improvements

77. The AI pilots of the high-speed aircraft now try to use their advantage over significantly slower aircraft using the hit and run tactics;

78. The AI pilots of the high-speed aircraft aim better when firing the guns;

79. A failed bombing run won’t cause an AI-controlled bomber to fly beyond the map borders;

Update 4.006

Dear friends,

Around a month has passed since the previous humongous update and we have another right here. Its changelist is not as so hideously long (it is still too long, however - more than 80 items), but some of them are quite important. First of all, two new Collector Planes are released, Yak-9 and Yak-9T. It was the most mass-produced Soviet WWII aircraft, the real victory weapon. They had very good flight characteristics, bubble canopy with armored glass on the front and back, good manufacturability. The modification Yak-9T armed with powerful 37mm gun NS-37 was designed for bomber intercepts but was also widely used against ground targets. Yak-9s were used in the Battle of Kuban, so you can use it in the Career mode at this theater of war as well as in QMB and multiplayer.

For Tank Crew customers this update adds a long-awaited Zveroboy ("Beast Slayer") - self-propelled heavy howitzer (assault gun) SU-152 based on KV-1s chassis and armed with a very powerful 152mm gun-howitzer ML-20S. While these assault guns were designed primarily for knocking out heavy defenses, at the Kursk Battle it was probably the only Soviet armored vehicle capable of killing Tigers and Panthers at far distances. Its 152mm APHE round weighed nearly 49 kg and its hit was lethal for a Tiger up to 2 km distance. Panther's thick and sloped frontal armor and 200mm frontal armor of Ferdinand tank destroyers could withstand it, but a HE shell hit at a Panther turret guaranteed to breach the thin hull roof near the hit area and APHE hit at a Panther side could knock it out easily. Being very powerful, SU-152 wasn't an absolute weapon of course. Limited armor and gun traverse angles, low ammo reserve and slow rate of fire demanded the combat skills from the crew and interaction of a group of these machines to reach its combat potential fully. Nevertheless, it was the first dangerous adversary for the newest German cats of prey.

This update also includes three new Scripted Campaigns – Kaiserschlacht, Spring Offensive and Lightning Strikes.

Kaiserschlacht and Spring Offensive are two campaigns developed by our friends at The Syndicate which tells about the same events from different sides of the front line of the spring of 1918. Although previously released to the public, these campaigns have been enlarged to include new unreleased missions. These are the first official campaigns for Flying Circus, allowing you to more fully evaluate the full potential and atmosphere of this great product. These two campaigns will be available free of charge to those who have already purchased Flying Circus: Volume One. There is an accompanying skin-pack for this campaign. It is available in the forum.

And for those who own the P-38J-25 Collector Plane and Battle of Bodenplatte, we also have a cool new Scripted Campaign for you - Lightning Strikes! This campaign was developed by our friend and talented mission maker Jaegermeister and it portrays P-38 combat missions in the skies of Europe from October to the end of December 1944. The campaign includes an outstanding number of missions, 25 of them, the last of which tells about the notorious events of January 1, 1945. This campaign is included free of charge to everyone who owns the P-8J-25 and Battle of Bodenplatte. There is also an accompanying skin-pack for this campaign and is available in the forum as well.

While new aircraft, tanks and campaigns are the lead stars of our sim, the most important change in this update is the release of the new graphics rendering engine based on Deferred Shading. This is the base for a new powerful shoot forward in the visual part of the project. It's impossible to unlock all this potential at once, but in this update, we already added a number of improvements based on this fundamental change. More natural-looking aircraft exterior, cockpit and instrument reflections, better-looking water surfaces - this is just a start.

Thanks to Martin =ICDP= Catney we have the external textures of 4 more existing aircraft in 4K quality: two bombers He 111 H-6 (BoM) and He 111 H-16 (BoS) and two Collectors Planes, La-5 series 8 and La-5FN series 2. The new textures push the visuals of these planes to a new level.

These huge additions aren't all - the update 4.006 brings many others which are also important. Aircraft FM and DM were updated basing on your feedback, Soviet fighter pilots have new visual model, there is a lot of changes for ground and naval units as well as for player controllable Tank Crew war machines. Multiplayer functionality has been also addressed. All this serves one purpose - constant improvement of the quality of gameplay and accuracy of the simulation. IL-2 Sturmovik team hopes that you'll enjoy all these changes.

Player-controllable Tanks

27. New quick missions for tanks - Tank Duel and Tank Skirmish;
28. All player controllable tanks have the transmission from forward-backward and left-right user controls to the simulated tank controls corrected, which improved their turnability at high speeds and reduced the tendency to enter a skid;
29. The commanders of the indirect fire capable self-propelled guns (SU-122 and SU-152 at the moment) can order the AI gunner(s) of their tank or tank platoon to fire at a set distance and direction;

39. All 45mm and bigger shells without tracers have a generic visual model (HE shells mostly and 122mm HEAT). This is true for AI units as well;

Aircraft Physics, Systems and Visuals

40. The maximum airspeed at which the pilot is able to bail out now depends on the vertical G-load acting on the pilot: the smaller positive G-load, or the greater negative G-load, the easier it is for the pilot to leave the plane;
41. A G-load indicator is added to the HUD. When simplified instruments are switched off, G-load is indicated without a fractional part;
42. A message about turret ammo replenishing and turret repair has been added to the technochat;
43. A message about servicing the engine oil system or cooling system in the repair area is added to the technochat. The service is performed if the engine oil or coolant have cooled down significantly during the aircraft stop (previously in these cases the player periodically received information about the repairing of the corresponding system, which wasn't really clear);
44. SPAD 13.C1: the roll oscillation of an AI-controlled airplane at a speed of about 200 km/h has been fixed;
45. Yak-7B polar curve has been corrected (the critical angle of attack was reduced, the inductive drag at large angles of attack was increased, the turn rate was reduced, the maximum speed and climb rate remained the same);

49. Bf-110 (G2, E2): aerodynamic characteristics corrected at supercritical angles of attack (the effectiveness of slats was improved, the drag was increased, and the nature of the stall was adjusted);
50. P-38J25 landing gear doors are visibly opened in the hangar;
51. Bf-109 G14 emergency engine power has been fixed (increased);
52. An aircraft won't appear underground when a season is set incorrectly or undefined in the mission file;
53. Sopwith Camel: when the option “Simplified Controls” is enabled in the difficulty settings, the automatic helper better stabilizes the plane along the roll axis at a high angle of attack;
54. Spitfire Mk IX: excess struts on the pylons were removed;

Aircraft Damage Model

55. The piston engines' combat survivability has been adjusted - the protection from the engine casings has been reduced, bullets and shells cause more damage to the crank gear, while shell fragments cause less damage to the engine.
56. All Flying Circus airplanes: hitting at the central section of the top wing now also leads to breaking the top wing (its left or right part);
57. The geometry of wing spars of all Flying Circus airplanes has been checked and brought into strict compliance with known sources. In general, now it requires much more bullet hits to break the wings of World War I aircraft;
58. The absence of visual and hearing disorders under the high G-loads for gunners in the single-player mode was fixed;
59. A rare bug has been fixed, which caused the fragments not damaging the airframe sometimes;
60. Pe-2 (ser. 35, 87): fixed rudders 'wobbling' when their control wires are broken;
61. Pe-2 (ser. 35, 87): a bug has been fixed that caused the left rudder to react to the controls slightly when its control wires were actually broken;
62. All Bf-109 fighters except E7 can now lose the left or right side of the horizontal stabilizer when hit at its central part (Bf-109 E7 has a central part of the stabilizer which can be lost by itself);
63. P-38: fixed a bug due to which the oxygen system could erroneously take damage;
64. Ju-52: fixed rudder 'wobbling' when its control wires are broken;
65. Fixed a problem with repairing aircraft turrets;
66. Fixed the undamageable machine guns in a number of aircraft turrets;

Ground and Naval Units

67. Ships have a more advanced physical model - they can be damaged by collisions, run aground, lay on the shore (and not sink into it), and lay on the bottom when sank;
68. All naval guns and howitzers fire physically modeled projectiles (previously explosions were created in the target area), making their combat use much more realistic;
69. All naval guns and howitzers have AP ammo available (around 10% of ammo reserve);
70. AAA guns can fire at the ground area (if the mission trigger Attack Area is set on the ground level);
71. The issue that made the first several salvos of an artillery battery too accurate has been found and fixed;
72. The issue with AI aiming the guns of player controllable tanks has been fixed;
73. Pz.Kpfw.IV Ausf.F1 and Pz.Kpfw.IV Ausf.G have their armor plates thickness corrected;
74. Groups and columns of AI-controlled ground vehicles can stop on shallow slopes (previously they couldn't);
75. Tank AI gunner no longer try to fire at flying targets;
76. Ground vehicle AIs can't spot targets through a dense enough forest (if at least 50m of the line of sight to a target travels through the forest area);
77. Field guns (AT and divisional ones) can fire at a maximum distance when given the Attack Area -> Ground command in the mission;
78. Aiming tables for several AA guns have been corrected;

Aircraft AI
79. The firing accuracy at air and ground targets depends on the AI pilot level;
80. View sectors have been corrected for Hs-129, Ju-52, A-20 and U-2 crews;
81. The minimal fuel reserve calculations have been corrected (previously they could cause AI pilots to RTB too early);

Multiplayer

82. The audibility of hits on the own plane has been corrected when the cockpit canopy is damaged;
83. New server-side option “Restrict tank AI gunners” blocks the ability of the tank commander to assign a dynamic object as a target for the AI gunner or order it to search for targets on its own;
84. Tech chat and handling tips are now governed by difficulty settings that can be enforced on a multiplayer server;

General Fixes

84. The recently introduced error in the armor penetration modeling has been corrected (it made the projectile speed - armor penetration function graduated and could cause an armor penetration in a case when it shouldn't occur);
85. Concussion won't cause the loss of hearing for too long;
86. UK and US careers (Bodenplatte) will work correctly with the Simplified Chinese language selected;
87. A rare error in scripted campaigns that could cause the progress to be lost after re-entering the game has been found and fixed.

Update 4.007

Dear friends,

We've decided to release the new update 4.007 relatively soon after the previous one, because the fixes and improvements it brings, while not being major, are nevertheless important for the project as a whole. We have heard your feedback on the view system improvements, added new options to the multiplayer functionality, which govern the usage of graphical mods, in addition, we did additional research on the workarounds for the Direct 3D functionality not supported by one of the graphics cards vendors. Damage modeling has been improved to take into account the control systems damage (rods, wires, etc.). We have also added a new German pilot model in the early summer uniform. The full list of changes follows:

1. Ju 87 D-3 dive bomber has been upgraded to 4K external texturing thanks to Martin =ICDP= Catney, including two additional official skins;
2. Aircraft control systems DM has been upgraded. The probability of losing control in a certain control axis depends on the control wires or rods configuration of a particular aircraft and existence of a reserve control channel (or its lack thereof);
3. Workarounds for the remaining graphical artifacts on AMD cards (like black contour around the aircraft when viewed from its cockpit) have been implemented;
4. New multiplayer server option “Restrict Injectors” allows the server hosters to restrict access for users with graphics injectors like Reshade or 3dmigoto;
5. Five new mappable (RCtrl+NumPad_Del,1,2,3,0 by default) zoom commands have been added that allow quick zooming to various degrees (minimal, maximal and 3 intermediate levels). Zoom value set by a mouse or joystick axis or keyboard keys is not affected by the new quick zoom and after releasing a quick zoom button the FOV will return to the one set by an axis. These new commands work in either 2D or VR mode. The old 'VR zoom' command has been deprecated (its equivalent is the new maximum quick zoom, RCtl+NumPad_0);
6. There is a new setting in the Camera options that governs the speed of the new zoom commands;
7. Tank commander binoculars give three times more powerful zoom than before (they give a minimal FOV that is technically possible in the game);
8. The current FOV (Field Of View) value is shown next to the in-game FPS counter (that is activated by Backspace key by default);
9. Gunsight FOVs have been corrected for all tanks;
10. German fighter pilots of the Battle of Moscow, Battle of Stalingrad and Battle of Kuban have a new visual model and a sidearm during Summer (new Winter model, also with a sidearm, will be added later when it is ready). Because of this, the default camera position and user-customizable snapviews (.svc files) were changed on Bf 109-G14, Bf 109-K4, Me 262-A, Fw 190-A3, Fw 190-53, Fw 190-A8 and Fw 190-D9. The updater should overwrite the old files for these planes with the new updated ones for you, but in case this action was blocked by antivirus software on your PC and you see a wrong view in the cockpit of these aircraft in the game, please copy the new default .svc files for these aircraft from \data\LuaScripts\snapviews\defaults to \data\LuaScripts\snapviews manually. If you haven't customized the view positions on other aircraft, you can just copy all the files from snapviews\defaults to snapviews folder;
11. Bomb holders on both Bristol Fighters appear correctly depending on the ammo loadout;
12. Pedals on both Bristol Fighters appear correctly in a neutral position;
13. The issue that made the detached parts of Flying Circus aircraft invisible in the multiplayer has been found and fixed;
14. Fw 190 D-9 canopy glass appear correctly at medium distances;
15. Fw 190 D-9 oil on windshield visual effect has been restored;
16. Destroyed static KV-1 model won't have white tracks when viewed from a distance;
17. Tank turret turn indicator won't visually 'jump' when passing the back position;
18. APHE rounds stopped by the armor won't damage outside objects;
19. Train wagons won't appear detached from the locomotive in some missions;
20. Guest crew members in multiplayer will correctly hear the sound of the tank turret turning;
21. Guest crew members in multiplayer will correctly hear the sounds of the hatches closing or opening;
22. Certain HE rounds explosions can be heard from an aircraft cockpit;
23. The arm model has a correct sidearm in it in VR mode;
24. The arm model won't drop a shadow when there is no body rendered;
25. The arm model has the correct size in VR mode;
26. Missing road segments that sunk inside the terrain have been corrected on Kuban map;
27. Random CTD in multiplayer fixed in case when other player tank have been spawned.

Please discuss the update in this thread.

Update 4.008

Dear friends,

Today is a very important day - we have just released update 4.008 that includes the first Battle of Normandy aircraft and the last tank for Tank Crew - Clash at Prokhorovka project. The first BoN plane is P-47D-22 "Razorback", the one so many of you had waited for. Battle of Normandy is at a very early stage of development, in the first quarter of the whole plan, but some of its parts are already taking shape - for instance, this new plane we told you in detail in the Dev Blog #225. This release officially starts the Early Access program for the Battle of Normandy and its owners will gradually get more and more content as soon as it is ready, starting with the "Razorback" today.

The last combat vehicle for Tank Crew - Clash at Prokhorovka is Sd.Kfz.184 "Ferdinand" tank destroyer, you could learn more about its history and design peculiarities in our Dev Blog #254. Tank Crew owners can try it right now. This fearsome machine completes the vehicle lineup of this unique and interesting 'Clash at Prokhorovka' project.

Another new addition in this release is the new historical campaign Ice Ring by Alexander =BlackSix= Timoshokov. Consisting of 15 scenarios, it is dedicated to very interesting and strategically important events of November and December 1942 in Stalingrad area - the actions of the special IL-2 group under the command of Major Leonid Karpovich Chumachenko which was tasked with interdiction of the German 'air bridge', the air supply route for the encircled Paulus' 6th Army. The campaign can be purchased here and requires only the Battle of Stalingrad module to play. Check this link for details.

Battle of Moscow owners also will find something new in this update - Martin =ICDP= Catney has finished the work on new 4K quality external textures for IL-2 mod. 1941. They, as well as Battle of Stalingrad customers, just received the new early war Luftwaffe pilot model in winter uniform and additional stuff - sidearm, animations for putting the glasses on when starting from parking and the oxygen mask when it is needed.

Another neat feature we want to tell you about is the support for a special in-game voice communications system known as SRS - "Simple Radio Standalone" (IL2-SRS). At the moment its support is not final, but it can be used with ease already. You can find all the info on how to install and use it here.

Less than a month has passed since the previous update, but again we have found ourselves posting a vast list of changes made. Sometimes the corrections mean that a user-created content needs to be updated as it happened now with height map corrections for Battle of Moscow, but the required actions are minimal, you can learn more about them here. Other numerous changes and corrections in 4.008 are listed below. Please note that some of them are quite important and should get your attention:

Main features
1. P-47D-22 “Razorback” heavy fighter is available to all customers who pre-ordered the Battle of Normandy. Early Access phase starts for Battle of Normandy project;
2. Sd.Kfz.184 “Ferdinand” tank destroyer is now available to all owners of the “Tank Crew” project, completing its 10 vehicles lineup; Official retail release of Tank Crew is TBD.
3. The new historical campaign “Ice Ring” is released and available for purchase (it requires Battle of Stalingrad);
4. Support for special SRS Radio voice comms app. The final version of SRS for IL-2 is still WIP by its author and will be released soon. We have created a special section in the forum dedicated to SRS instructions and discussions - check this link;
5. The 1941 IL-2 attack aircraft now has 4K quality external texturing thanks to Martin = ICDP = Catney;

Update 4.009

Dear Friends,

One month has passed since the previous update, and once again we are ready to present you with a new package of innovations and improvements. The main additions in this version are the new campaign Hell Hawks over the Bulge, new free summer map Velikiye Luki, and new single missions for the Bodenplatte aircraft and Tank Crew tanks - now each model of these modules has a single mission designed for it.

We have also added more beauty to our simulator, in several meanings of this word. First, the P-40E-1 Kittyhawk received 4K texturing of the outer model by Martin =ICDP= Catney. And second, U-2VS, Yak-1 series 69 and Yak-1b series 127 now have female crews option! U-2VS this was done in the memory of the 588th Night Light Bomber Aviation Regiment, known under the nickname "Night Witches", and for Yak-1s in the memory of the fighter pilot Lydia Litvyak, the most effective female fighter pilot of World War II.

This update includes a total of 78 points of changes mostly targeted at the two main areas - AI improvements in and the refinement of the recently completed line of player controllable tanks. There are many extremely important changes in this list for other areas of our sim as well.

Update 4.501

Dear friends,

We just released the new update - 4.501. Its shifted version number means it is a kind of a milestone and it really is. First, the research we did on the community opinion on the aircraft spotting allowed us to make many improvements to this important part of the sim. The distant LOD scaling system has been adjusted, their lighting has been made full, atmospheric haze option and an increased MSAA level have been added. We're sure that this update will make the online multiplayer experience totally different from how it was before. Now our next target, for the next update, is the improved pilot G tolerance model we do after asking the community taking the account the new reference data provided by the community members.

Please take in attention: adding Haze option to the mission format makes previously saved .msnbin mission files obsolete. Delete them and save the new version using .Mission files.

In addition to these very important changes, today's update brings you the new campaign 'Wind of Fury' by Alexander =BlackSix= Timoshkov that is included in the Bodenplatte module. This means that our promises on what Bodenplatte will include are finally fulfilled. Of course, it doesn't mean we'll stop improving it, for instance, now we plan to improve the Rhineland Career mode.

Also, P-39L-1 "Aircrobra" (Battle of Kuban) and Bf 109 G-6 now have 4k quality external texturing created by Martin =ICDP= Catney. The work on bringing all the aircraft in the sim to 4K texturing continues.

Tank Crew gets the last planned features for its release in this update, making 4.501 a milestone for it as well. The new turret and gun control mode and fixed visor cameras were requested by the community for a long time and they are available now.

We think that this update will mark an important step for our sim and we hope you'll enjoy it!

Main features
1. The new scenario campaign "Wind of Fury" is now available to all owners of the Bodenplatte project for free;
2. P-39L-1 "Airacobra" and Bf 109 G-6 fighters now have 4K quality external textures created by Martin = ICDP = Catney;
3. The long-range LODs scaling system for aircraft has been adjusted. Aircraft spotting at short to medium distances, especially when using wide camera angles, is greatly improved. The visibility at distance has been adjusted to be closer to reality.
4. Alternate Visibility has been renamed Enhanced Visibility: this mode gives a much greater increase in aircraft visibility at long ranges compared to the new standard visibility. At medium ranges, visibility is also significantly improved compared to the old Alternate Visibility option;
5. MSAA x8 option has been added, but please note that this level of AA is very demanding to the graphics card performance;
6. The atmospheric haze density option has been added to the Quick Mission Builder. Its minimum value corresponds to the haze density available earlier;
7. Dawn/Dusk Fog option has been added to the Quick Mission Builder. This option is available only when the haze density is set to half of the maximum value or more;
8. The haze density option (from 0.0 to 1.0) is now stored in a mission file. Radiation fog appears at dusk if the value of the haze is more than 0.5 and the weather preset name contains an odd number at the end. The denser haze makes it easier to spot other aircraft against the background of the landscape when the distance from the observer to the target is much less than the distance from the observer to the landscape behind the target. This can be used when designing multiplayer missions for game servers;
9. Distant levels of detail (LODs) of the aircraft now have the same surface material setting as closer and more detailed LODs, making the lighting of distant aircraft much more realistic and enabling reflections and glints when the relative position of a contact, an observer and the light source(s) is right;
10. In a multiplayer game, a tooltip has been added to the list of game servers when hovering the mouse cursor over the difficulty preset icon. This tooltip displays all the difficulty settings of this multiplayer server;
11. This information is also available in the multiplayer server lobby (“About the server” section);

AI improvements
12. AI wingmen keep the optimal climb speed when the wing leader is far and higher;
13. AI aircraft now use combat and emergency engine modes for a fastest possible climb when following the terrain;
14. AI fighters now more actively attack maneuvering targets at lower speeds;

Player controllable tanks improvements
15. New control mode allows aiming a tank gun using a joystick (or buttons);
16. Aiming the tank guns and machine guns with the mouse is more convenient;
17. Fixed cameras added to tank visors and other observation devices. Loader viewing devices are, most often, can be used from the gunner's station. You can cycle the views using LShift + V keys;
18. The target marking cursor when giving orders as a tank commander is visible at any settings;
19. The current sight or observation device is indicated;
20. In multiplayer, a connected player in someone else's tank will correctly see the messages from the loader and see the ammo information in the HUD;
21. The time required for repairing the tank systems outside the service areas is doubled;
22. The projectiles correctly penetrate the armor if they hit certain extremely thin areas of the object's surface (a rare issue);
23. Ferdinand: the inverted direction of inclination of the panoramic viewing devices has been fixed;
24. An SPG AI gunner correctly fires at an invisible target by the order of the SPG commander (using the direction and range);
25. Fixed the issue where the AI gunner did not follow the commander's instructions to choose the ammo type in certain situations;
26. Pz-III-M: the KFF 2 binocular periscope is functional (when using the camera selected by LShift + V);
27. SU-152 commander can't use the panoramic sight when unbuttoned;

Other changes
28. Fixed an issue with parts of the canopy and cockpit instruments that could not be restored after repair;

Update 4.502

Attention Pilots!

On this chilly Autumn day, we’re releasing a large update to IL-2 Sturmovik - update 4.502 is here! The star of this update is the new Hurricane Mk.II Collector Plane. This plane has the most modifications in our sim and with a wide range of weapon loadouts available this makes it 5 aircraft in 1. You get several variants including the IIa, IIb, IIc, IId and the one with the Soviet armament. The famous Dust Filter and Merlin XX engine with +14lb boost are also available. On top of all that, you can use the new bird in the Career mode right away - we added it to the Battle of Moscow and the Battle of Stalingrad careers. In addition to the Hurricane we have added the legendary С-47А "Skytrain" transport plane for the Battle of Normandy. The C-47 is AI only, but adds a new dimension to our missions and variety of Allied aircraft you will encounter in the sky. It is also great for mission makers who want to make supply runs an integral part of their battle. And finally, Battle of Moscow players receive new 4K quality skins for the Bf-110 E-2 thanks to our talented friend Martin =ICDP= Catney.

On the technical front we have added a new and more realistic G-load physiology modeling system. This work was described in great detail in our Developer Diary #263. Additionally, a lot of work was done on all the aspects of the ground battles, significantly improving the quality and realism of Tank Crew engagements. There are many improvements to the pilot AI as well in this update. And finally, long-awaited Career mode improvements are finally starting to arrive.

Main Features
1. The Hurricane Mk.II Collector Plane is now available to its owners;
2. The C-47A transport aircraft is now available in the sim as an AI enemy or ally in the Quick Mission mode. It can also be used in the custom missions as an AI transport aircraft;
3. Female crews got female voices in the radio messages;
4. Pilot physiology modeling has been improved significantly. This is described in detail in the Developers Diary #263;
5. The zoom function now works correctly on VR devices with canted displays (Pimax) without using the performance-intensive Parallel Projection mode;
6. New multiplayer scenarios, including Cooperative ones, are added for Tank Crew (you can create a server directly from the game by selecting a scenario or scenarios from the Multiplayer\Cooperative\TankCrew or Multiplayer\Dogfight\TankCrew folders);
7. 4K external textures for Bf 110E heavy fighter (Battle of Moscow) are added thanks to Martin =ICDP= Catney;

Update 4.503

Dear friends,

Less than two weeks (wink-wink) have passed since the previous update and we just released another - 4.503. It doesn't contain so many changes, but it adds a new aircraft to the Battle of Normandy Early Access - Bf 109 G-6 late. With the MW-50 injection system engaged, it was a formidable machine capable of confronting the Allied fighters of that time. Normandy map and Battle of Normandy Career are still in development according to the development plan, but you can already use the new addition in the Rheinland career - we've added it to the five groups that have been using this Bf 109 during the Rheinland career timeframe historically.

Also in this update, 4K external texturing for the German heavy fighter Bf 110 G-2 (Battle of Kuban) is added. As with other updated planes, this change is a big visual improvement. There are several improvements for Tank Crew as well in anticipation of its official release. The full changelist follows:

1. German fighter Bf 109 G-6 Late is available for Battle of Normandy owners;
2. Bf 109 G-6 Late added to the following Rheinland Career mode (Battle of Bodenplatte) groups the player can join: I./JG 3, II./JG 11, III./JG 26, III./JG 27 and II./JG 77. It is also used by AI-controlled groups III./JG 1, III./JG 4, III./JG 53, I./JG 76 and III./JG 300;
3. German heavy fighter Bf 110 G-2 has 4K quality external textures created by Martin =ICDP= Catney;
4. Pz.Kpfw.III Ausf.M player controllable tank now has a lower armor plate under the rear overhang modeled;
5. All player controllable tanks now have bulkheads (made of regular steel) between the fighting and the engine compartments;
6. M4A2 tank commander animation corrected (due to an error he could be wounded by enemy MG fire when inside the tank);
7. AI-controlled ground vehicle tracks are resistant to combat damage similarly to player controllable vehicle tracks
8. Combat damage resistance has been corrected for several player controllable tank tracks;
9. The maximum speeds of the simple AI-controlled tanks now correspond to the detailed ones;
10. Tracked and wheeled vehicles move up the hills faster and more realistically;
11. Recently released Tank Coop missions were improved;
12. Tank gunner AI prefers APHE ammo when it estimates that the target armor can be penetrated with different ammo types at the current relative position;
13. Tank driver AI has been improved, resulting in less jerking while driving backward;

14. Oxygen mask breathing sound has been toned down a bit;
15. Bf 109 G-2, G-4, G-6, G-14 and K-4 wheels texturing has been improved;
16. Hurricane Mk.II compass now has fluorescent needles;
17. A rare issue with generating a new day in the Career mode has been addressed.
