Korea. IL-2 Series Dev Blog #10: Terrain and Ground Object Improvements

[MajorMagee]

The vehicle tire contact with the ground is pretty jaunty. Perhaps the physics models are still waiting to be developed.

and it would be impressive if the trains and locomotives could have weight, inertia and an bit more of a damage model.

Same with other vehicles, when totally destroyed (blow up) they should not stop instantly and switch in one frame to the destroyed black model.

That Last derailment in Kansas City was not momentum. That was a backing move, made to fast with empty (center bulkhead flat cars) cars behind loaded cars. The cars stacked up like that due to, even with modern brakes trains take a bit to stop, the engines (IIRC 2 engines) pushed the cars.

 

I had to help clean that one up.

 

In my defense - they did end up derailed 😄 Thanks for the additional info though!

That is the basic issue with the current implementation - when fully destroyed vehicles get replaced instantly with a completely destroyed 3d model which is simplified and doesn't have physics (to save on resources)... and this is obviously the most jarring when it comes to trains (which have thousands of tons moving at speed).

Yes, I did raise this years ago when tank crew came out tanks have same issue and  when you shoot a truck up close it's more obvious because you have more time to look at target:)

 

Btw I hope also bullets/shells impact on the ground would improve, time of the dust- not almost instantly despairing and always  the same copy paste look plus not accounting for wind direction and it  speed. Those particle effects need more attention to be something special but IMO add so much to improve immersion. Where il2 GB is lacking -  one minute after bombardment or strafing whole place looks peacefully again just objects have the same final destroyed look , this remove some ground attacker satisfaction.

Adrenaline is a powerful drug, so I think that it's fine that they get out quick.

 

Of course, in an ideal world we would have a few different animations, including one for an escape with a leg injury, or even soldiers helping each other.

The soldiers run animation speed doesn't look realistic, something is wrong you can feel it's artificial. BTW after the crash ppl are confused, panicked, wounded or try to assess situation, have to unfasten the seat belts (this could be not a case) anyway in modern car crashes seldom someone, jump out instantly. Anyways same run speed and in the same direction, distance for all soldiers also looks artificial. The smoke and mirrors could work to fool our brains but as it looks now need to be improved a little bit.

Yeah, but to be honest I didn't really care much about crashes, because in reality the drivers should just park up and run out of their soft-skin vehicle when attacked. The entire scenario of a truck crashing doesn't seem the most relevant to me.

I see and understand you but devs do produce a movie showing this as one of the key thing in that footage.

That is an awesome little video and the detail and immersion are incredible, but at what cost to the overall flightsim performance? I guess we will have to wait and see, but it would stand to reason that the hardware will have to be extremely capable to run IL2 Korea with all the bells and whistles turned on.

If it won't run on my old pc I won't be buying it... retired now, and I'm pretty sure I'll never be able to afford a top end rig anymore.

What I've got will have to see me out the door!

Me to Trooper. I have just finished an upgrade to a 7800x3d chip, Gskill 6000 mhz ram on an Asus B650 MB that my friend got me for $425 brand new with trade in of my old chip, ram and MB. Don't ask me how as that was a steal, but he did. I would like a 4090 but I refuse to pay 1800$ for one. My old 3090ftw will have to do.

 

Luke on another note, will IL2 Korea use multi thread processor cores or single core mostly?

Same here Gents, I'll be retiring next spring.

[Trooper117]

For me now it's all a question of priorities... I'm moving from a house to a bungalow at the moment, I'm not getting any younger, and have to look to the future quality of life I will need. Plus, moving house is a very expensive thing to do here in the UK.

Also, as much as I like to flight sim and play games, my bigger interest is to maintain and ride motorbikes... if you don't or have never done that you won't understand the joy, thrill, feeling of freedom or satisfaction that for me is almost spiritual... I intend to be riding bikes till the day I die (if possible)...

[BlitzPig_EL]

I rode until about 2 years ago.  Walked out to the Bonneville all geared up and ready to ride, and something in my head said "no".  Walked back in the house, took off my gear, and two weeks later sold the machine.  I loved riding, and don't regret a single day of it, but it was time.  I don't regret that decision, as riding here has become a reward no longer worth the risk, what with all the numpties looking at their screens...

We'll talk about that in either a blog post or a video at some point. The video this week is planned to go over the questions submitted to Han and Gavrick about flight modeling.

The animation will normally play in the context of being strafed... while I understand your point, I think the behaviour of people in a car accident (e.g. where it is often safer to remain in the vehicle awaiting help) and the behaviour of people realising that they are in a convoy that is in the process of being strafed and bombed is likely quite different. In that situation I would probably run as fast as I could, in a straight line, for about 100 metres (even if I had minor injuries or was disoriented).

[LF_Mark_Krieger]

Another thing not exactly related with the video because it isn't a matter of animation but the locomotive made me think about it is the damage points of the locomotives. Most players when playing in servers think they are too difficult to destroy compared in what we see in most guncams. I admit too that possibly the selection of images of planes strafing locomotives is biased and there are more images of locomotives exploding with just a brief straffing that it happened in reality? Don't have data about it, but I have the feeling that locomotives in GB are too resistant to straffing attacks.

Somewhere on the forums, I'm pretty sure I linked to a British report based on interviews with railway crew. If I recall, the take-aways were that rail crews mainly fear being strafed, and most of them were unaware that rockets were being used against locomotives. I have the impression that there may be survivorship bias - that some crews came back with the experience of their fellow crew members being shot or hit by fragments due to strafing - whereas ones which received direct bomb hits didn't survive to be interviewed.

 

Standard defensive procedure was to bring the train to a halt (to allow escape), while making as much steam as possible (to produce a smoke screen), and there might have been a mention of reducing boiler pressure (but I don't remember it clearly).

 

My old estimate was the locomotive boilers were about 14mm thick, and made of steel (not face hardened steel armour)... so they could be penetrated from most angles - but would also be less likely to catastrophically fail than actual armoured plate might be. Poking holes in the boiler might also reduce pressure (effectively creating additional safety valves). You only get a boiler explosion when the level of steam pressure in the boiler is much higher than it should be. So, the conditions required for a catastrophic boiler explosion aren't guaranteed... I gather quite a few locomotives were at least partially salvaged and repaired after attacks. Anyway, we should find that report! My memory isn't that reliable.

[Aapje]

It seems to me that a repair of a boiler would be quite a bit of work, so the train would probably be out of action for some time. That mattered too, not just a full destruction.

All of them were staged (especially the first one - I think they built something of a ramp to divert the train smoothly over the side of the embankment)!

 

Your point about momentum stands though!

 

Speaking of a much smaller train from 50 years earlier: "The locomotive brakes alone were insufficient to stop the train, the momentum carried it into the buffers, and the locomotive crossed the almost 30-metre (98 ft) wide station concourse, crashing through a 60-centimetre (24 in) thick wall, before falling onto the Place de Rennes 10 metres (33 ft) below, where it stood on its nose."

 

 

if the frames don't fail and the couplers manage to hold even a low-speed derailment will tend to involve the cars just continuing to move forward (pushed by the weight of the cars before or ahead of them) and zig-zag until they hit something capable of resisting a few hundred tons of steel):

 

Definitely didn't expect to see the place just down the road from me appear here...
