Since last paths some of my squad mates and me were suffering this ridiculous Bug on Multiplayer. I saw as well some more people with this problem

 

Description of the BUG:

 

Planes are just invisible. The bug can happen on different ways. Some times you just can not see some plane, sometimes you can not see any plane but the rest of the people can see you. Sometimes the plane apeears just after using lights or firing and sometimes that just not happens and every plane on the server is invisible. 

For the every invisible plane you need to reset the game or just land and make other sortie, but that is if you realice that you have the bug. If not some invisible plane can appear on your six to kill you and you are not able to know it because you may see your squad mate. 

 

Of course this bug ruins completely the gaming experience and every serious aproach to the sim keeping yourself alive etc. Just make no sense to go for survival or streaks because some day some invisible plane can just kill you. 

 

Recordings of the bug:

 

I encourage you to post any recording you have of this bug here. For the momment I suffer 4 times this bug and I recorded the bug twice. 

 

-The first time I was landed with A20 on the middel of the runaway and my mate reported me that I was invisible and I suddenly appeared when I turn on lights. This mate also had the bug once on the WoL server and he could not see anyone even his squad mates. 

 

-The second time I was looking at my six and the plane just teletransport behind on the momment he oppened fire. Not able to record because I was instant killed. 

 

-The Third time I was on Stuka sortie on WoL. My mate was shot down by invisible plane while heading home far from flack. Any of the gunners recognice the menace. Here is the video

 

The last time was on TAW server. Was a P2 sortie. I was flying on formation with my mates and I could not see them. 

On the video you can see the view fom my cockpit live recorded and I have the track as well from my squadmate. Audio is synchroniced from my recording with his track as well to understand the time line. Voices are on spanish but you can see the important. 

 

The record on live video prooves perfectly that the isue exist. So there is no room for interpretation here. I saw so many people saying that the track files are bugged etc to give kind of explanation but there is no excuse possible taken the video from two different points of views.

geramos;  could you post a video of the external of the stuka before and during it going down?

I was recording with shadow play as I allways make because I dont like to have 200 tracks on the game so sadly i have no track. 

Even with that I preffer this way because tracks are buggued sometimes as well so are not reliable. This way we can see what we really saw.

 

My squadmate has the track of the P2 sortie so we will se there how clearly there are invisible planes from both sides track and live video.

I think I dont need to explain why this kind of bugs are unacceptable and kills all the realism.

Salutations,

 

Has the 'bug' been observed during any or your single player missions?

 

If not, I suspect it has something to do with the internet server connections.  😐

I did not observe that bug on single player. The bug is there since last paths not before and my squadmates suffer this as well now, not on previous versions of the game. So something has changed on the game that let this happens so is just not a server conection problem

This situation will not be allowed to continue indefinitely and will be sorted out I'm sure. It is obviously frustrating. :salute:

Oh, is the same anomaly experienced on a server other than TAW?

There was an invisible plane bug in 2015. I documented it on a few tracks in the forums. At the time, the planes remained invisible until they fired their weapons. The devs had people who wanted to assist to make a change in the startup.conf so that when when flying invisibility would be logged. The log and tracks, if available, were submitted to the devs by a number of people including me. After a period of time they did solve the issue. I wonder if this is a new bug or the old one rearing it's ugly head.

 

On April 22, 2015 the devs released v1.011 (link below).  They announce the following:

MAJOR NOTE:
A special logging routine added to catch a bug with invisible planes in multiplayer - if you encounter this bug, please leave the server, exit the game, then zip the file \data\MP_InvisibleAirplanes.log and send it to us!

Noticed this first time today, i attack 109 and at same time my tm8 attacked 190, then i noticed onother 190, but my tm8 Ripgrunwald after he finish his 190 was saying he dosent see any other 190 in area, and i could clearly see this 190 climbing abow my tm8 and starting to contrail and then doing attack at me ( both of us contrailing on winter map) and still my tm8 could only see me, and then that 190 go for my tm8 and only when 190 hit my tm8 it got visable to him also, and then he say that he could see 190 just shooting for long time in empty space ( i saw only 190 shoot at him and stop).

 

It looks to me like some data pacages get lost, dont look like any abuse as i could clearly see 190 that my tm8 could not, and only when 190 hit him data probably get recived by my tm8 from him and made 190 visable (190  guy that my tm8 could not see was on VR and from russia on russian server if that makes any differance, dont seam like ping could be problem)

I have noticed this for some time - and I seemed to remember a "recent" update where a fix for this was mentioned (and it seemed fixed for me) and then it seemed like that line got removed from the patch notes.
I might be wrong of course.

Or maybe this is a repo-merge error/fail, maybe this is due to an unresolved third-party software issue.

The bug itself is very weird, because it is hard to find any sort of reproduceability or categorization when it is likely to happen.
I have noticed  - and tested with other players as well - the following occurrences:

  • you look at a plane and it just vanishes, not a renderdistance error, you can be at a stable distance or coming nearer (especially bad when you try to dive on a plane)
  • you have a plane rendered, you look away (rotate away your rendercamcone) briefly, rotate your view back on it.. and it is gone (but IL2 works with a renderglobe, not a camcone as far as I know)
  • you are in an area.. and not everything is rendered for everyone, that INCLUDES non-playable assets like AA puffs, AA tracers - and it is seemingly not related to density, it can happen with 2 players or 10 players in the area
  • it is not FPS-related, it can happen at any framerate from low to reasonable to high

We are talking about a bug, not an exploit (maybe there is an exploit utilizing the bug but that still is not the issue) - a bug that seemed fixed again within the span of this year.

Maybe it is LOD-distance related where detail-exchange in models and skins lead to a non-render that just stays over a certain amount of ticks, maybe it is package related.. or it is even due to low-ping vs high-ping packets "drifting" over the server-refresh for a few cycles.
But it seems so arbitrary that it is really difficult to come up with anything to categorize towards a source isolation by elimination.
And since this includes NPC-action assets, maybe this is not (just) an old bug coming back but an entirely new one or a related or merged new one.

IMHO even a temporary 1-pixel fixed minimum render outside the renderglobe and in all exception catchers within the renderglobe would not fix this - since assets just vanish and pop back in.

Tank crew online missions you have the odd tank that is of extra-terrestrial origin that phases in and out of dimensions too.

 

It is there. Oups it is gone.Oh it is there again. Seems to happen more with AI tanks.

I had a sortie last month where I was shot down by an invisible plane. This was the DED Normal server with icons and GPS on. Unfortunately, I hadn't recorded the sortie, but I'm fairly confident it was this one (http://72ag-ded.su:8080/en/sortie/1231180/?tour=45).

 

In my instance, I could see there was an enemy plane nearby on the map,  but I couldn't see it, or get an "F8 Padlock". I ended up flying straight because I guessed it was a certain pilot who practically flies in orbit on a busy server who was out of range, and I'd have warning if he came within threat range :). Turns out, it wasn't, and I was killed by a stream of bullets that seemed to be coming from nowhere. 

 

The pilot actually apologised for shooting me down. He had nothing to apologise for, I'd have done the same if situations were reversed, and I suspect he thought my plane was too damaged to manoeuvre,  but that definitely want the case... I just couldn't see him. I knew there was no foul play involved, and suspected a bug,  but hadn't heard others had experienced this at the time. This is the first and only time I've encountered it.

 

I also knew it was different to the old issue where you could carry on flying without an icon if your rudder was shot off, because that still allowed you to padlock on the plane, and the plane itself was not invisible.

Due to the multiplayer experiences i had during the last few days, i have the feeling it got even worse.

Yeah can confirm its happening very often now and even for planes you dogfight. During last weekend on TAW I've met an I-16 that just dissappeared during scissors :( 

This kills multi really.. Now imagine what mess it will be when the view distance is increased to 100km while they cannot do it properly now lol.

On Taw I saw someone going on an arfield. Flack was shoting just at the air. Was invisible for all my fellas. I have the track so i will make other video.

Just kills realism. What is the point of going for a top streack if some invisible plane can just sit on your six and kill you undetected..

I already posted a clip, where this was happening in the Multiplayer Bug Thread, but the more evidence we have, the better!!

This keeps happening to when flying. However I don't record tracks or take videos, and there's always the possibility that I didn't see the plane, it was on my low six and thus hidden, and so on. So I usually don't press the point.

However when tanking on a few occasions I have seen

* tanks initially incomplete, with a missing (or transparent turret), which appeared later

* tanks initially entirely invisible which then appeared, part by part.

 

I want to stress that there is also a completely different thing going on with 'furniture' tanks (or other objects) , where the object is rendered differently and completely disappears as you zoom out. Then you zoom in and it's back. I've seen this effect with an AI stuka which kept disappearing every time I zoomed out and reappeared as I zoomed in. There must be a setting in the mission editor which allows for this, maybe to reduce load?

 

But regarding the missing parts of player controlled vehicles. Would this be an indication that the online multiplayer is implemented in such a way that the actual 3d models of vehicles are sent? This seems hugely inefficient to me (because the client can have all the 3d models) but would maybe explain the struggles with the netcode on today's fast broadband connections when, already at the end of the 90s, I was playing warbirds and there were no such issues.

 

If parts of vehicles are actually transmitted and rendered this would seem rather exploitable to me. In such a case, in the interest of fairness, I would suggest to have an implementation where, if missing parts can somehow be detected, a cube or something, the size of the largest vehicle, is rendered instead of an incomplete vehicle. Or something like that, which would make it easier in an MMO for the players to detect that something is amiss.

I have an example of the invisible aircraft where it is not friend against foe, but friends not seeing one another which is the clearest example we have experienced.

 

Whilst flying on KOTA server on the 21st, we had 4x Spitfires escorting 4x Pe2's. The 4x Spitfires took off from the Anapa base, and the 4x Pe2's took off from Airfield-3 which was further to the north east, so two separate airfields. All the Pe2's could see one another, and the Spitfires could all see each other also.

 

Meeting up over the sea to the south of Anapa it turned out that 3 of the Spitfire pilots could only see 3 of the Pe2's, whilst the forth Spitfire pilot could see all four Pe2's, so you could imagine the conversation going on, lol.

 

Anyway the Pe2's test fired their guns and then the invisible Pe2 appeared to the 3 Spitfire pilots that could not see it orginally. So the invisible Pe2 by firing its guns made it viewable, which could also be the reason that the defender does not see the attacker until that moment.

 

See this report on the experience also:
https://forum.il2sturmovik.com/topic/52131-invisible-enemy/?do=findComment&comment=811565

 

I took a small tacview of the incidence to prove we were not going all mad.

 

Now I know this is not going to be easy to fix through one example, but hope it helps.

 

As it does make you think that the multiplayer experience is not what you are seeing all of the time. Also maybe the possible impact it could have on the air marshal mode that is coming out in the future.

6 of the players are in the UK, 1 in the Netherlands, 1 in Poland, as a help to what ISP they are using.

Still happening. Happens to me, i would say around once every 10 hours of play or so. It never happens on my first sortie after I login. Some times, I think I was just jumped by a superior adversary or was attacked from a strange angle. This last one, I suffered 3 attacks in less than 5 seconds, which means that he was right on my 6. I completely looped and looked back and there was nothing there. He got a head kill, so I got to see those few seconds of the plane falling down. There was nothing behind me or in the area.

 

The main problem is that there is no warning of any kind, and now, every time I spend more than 5 minutes without seeing any friend or foe, I am always thinking I might be getting the bug. It is really ruining the experience. You can say what you want about War Thunder, but I never saw anything like that over there, and it's a god damn free game!

Encountered in FC, reported first byUS93_Larner :

Two invisible Fokkers D.VIIF jumped two Spads.
Fokker pilots were able to see each other and Spads all the time.
Spad pilots spotted Fokkers at long distance, then stopped seeing them.
Fokkers attacked separately, couple of minutes apart. Each stayed invisible until just before opening fire (when Fokker #1 fired, Fokker #2 stayed invisible).

So, the bug is reproducible and based on in-flight conditions (both Spads flying together were affected same way, both Fokkers flying together went invisible at the same time). 

Zooropa_Fly noticed that planes observed to go invisible (Albatros D.Va and Fokker D.VIIF) have same strange skin property.


 in 'advanced properties' of an ai DVIIf and Alby - there's a dropdown option <multiple> that doesn't exist in any other plane, and probably shouldn't.

It's there by default, and despite selecting one of the skin options, it reverts back to <multiple>. So it can't be changed from the mysterious <multiple> setting.

 

If the issue is seen with these two planes then maybe there is a connection.
