Disappearing objects in VR

[SvAF/F16_Goblin]

Hi mates,

I have posted this as a bug in the bug report thread but I want to know if anyone else noticed this? I searched but couldn't find anything about it.

All objects like planes and trucks (so on so forth) disappears in the right eye on the RIFT and that makes tracking and spotting targets in flight really difficult and it's an immersion breaker as well.

It's roughly in the last 10% of the right screen that this happens. The interesting part is that the flames from a burning plane is still visible but the plane itself disappears!

That means someone can sneak up on you from the right and you'll never see him until to late.

Please look into this because when large view HMD arrives (Pimax) this will be a huge problem.

[RedeyeStorm]

Yes there are two threads about this issue.

[SvAF/F16_Goblin]

Ok, my search "mojo" needs improvement I guess ?

[RedeyeStorm]

Fraid so, but no solution has presented itself.

[SAG]

did you happen to remove the foam from the headset? the problem is more apparent it you did that

[Sgt_Joch]

If you are referring to objects not being rendered at the very edges of the peripheral vision in the Rift, that is a common complaint in many games if you do a quick google search. It seems to be a limitation of the Rift, not sure what the devs can do about it.

 

Personally, I have never noticed it in game.

 

quick review of the posts regarding other games surmises it is linked to FOV and objects not being rendered outside of a defined FOV since objects which a player normally cannot see are not rendered to save CPU/GPU cycles. I would guess there is a mismatch between the Rift FOV and the FOV rendered in game.

That might be the case with airplanes because they dissapear right at the edge of my fov. I do not consider that much of on issue. Ground targets are a bigger problem because they are only visible in a limited forward arc, say 45 degrees (not sure of exact angle). Best seen with outside view. Just move the camera around your plane and it is obvious. That is definitly Il2.

Might be something to do with IPD? IIRC, when i decreased my IPD from the headset switch, objects stopped disappearing.

[Sgt_Joch]

just ran a quick test in QMB vs ground targets, but still not seeing an issue on my system. Ground units like artillery batteries and trains are still being rendered at the very edge of the lens. 

[SvAF/F16_Goblin]

Interesting, I only experience this in Il-2, not in DCS or any other VR game/sim. I have to experiment more. But I definitely can't put this on the Rift because no other software exhibit this behaviour as of yet. Not a deal breaker, IL-2 is still the best VR flight sim present

[JonRedcorn]

This exact issue is something I've been complaining about for a long time. Have to say the vr limits being improved was absolutely the best part of the last patch.

Yep. Spamming the forums will 100% get this fixed. Nice one. Keep up the good work.

I take it you are being facetious for some reason... 

 

Im trying to bring to light the biggest issue with my enjoyment of the game with hope that i can find a solution. What is your motive?

My apologies, something weird with the web client. It seemed like you had responded to 4 threads with the same message.

do you have any suggestions about the topic at hand?

 

any way to better reach developers about this seemingly glaring issue that has existed for so long?

[SCG_Fenris_Wolf]

Please name headset model, software used (openVR or opencomposite), and type of IL-2 client (via Steam or standalone) ?

[TheWarsimmer]

The old trick of making sure that pilot head movements are not tied to anything no longer works. It has always been a problem, but this is the worst state I have seen it in. I would say the ground pounding is not viable anymore. Here are the major observations I have noticed:

 

*Ground units tend to disappear whenever you zoom in on them

*The locomotive is usually the only part visible on a train anymore

*If you look at an object like a pak that is surrounded by sandbags, sometimes you will see the sandbags but not the pak. It is usually difficult to see anything at all, however

 

It's in really bad shape right now. To the point of not being able to ground pound at all. Some ground units refuse to pop in regardless of the angle of approach, and at times it seems random.

 

As far as what I use: Rift S through steam vr w/ voice attack.

 

EDIT: As far as what it looks like visually, it's exactly as bbz's vid.

Here's another video in addition to bbz's to further clarify the issue. Here you can see only the locomotive, and armor does not show up until right right on top. I wonder if the devs are aware of this? EDIT: Posted updated video to display multiple sources and instances.

Noticed as well that the units just show up sometimes in VR. This literally makes Il-2 totally unplayable for me, sorry. I don't want to fight against things that have cloaking devices. Also happens to planes BTW. CV1 and Q1 (VD) here, running via 08/15 SteamVR and Oculusware 21 up.

[squidboi]

I've noticed this sometimes too, and another thing I've noticed is sometimes the grasses only render in one eye which makes a really weird effect, so normally I just disable all grasses.

[SCG_Fenris_Wolf]

This is a bug tied to frustrum culling. Either center or range.

 

What are you headsets?

 

I gathered so far

Rift CV1 /SteamVR

Rift S  / SteamVR

Quest1 / Virtual Desktop via SteamVR

 

Please list yours, if it hasn't been called yet.

[71st_AH_Mastiff]

Rift CV1 no issues for me.

[messsucher]

Vive Pro Linux/SteamVR, works like a charm.

Not sure if this helps, but just in case. I have noticed in multiplayer you will at times be able to see the pilots sitting in the cockpit next to you at spawn, but as soon as you move your head outside of that angle they disappear. I'm not entirely sure how centering factors in, because I will often see the pilots when they are in the corner of my eye, but lose them if facing head on. Oddly (as it appears to contradict the pilot observation), I have noticed that the zoom function does not cull ground objects if you approach dead center, but the vision cone is extremely small, per bbz's vid.

HTC VIVE original with STEAM VR

[SvAF/F16_Goblin]

Reverb version 1 and stand alone game version with WMR and Steam

[GOA_AveFenix506*VR*]

Oculus CV1 here, i have the same problem especially when im making ground attack at very low altitude , another bug that im seen constantly is the disapearing of the crew on the planes next to me in the airfield when im running the spawn for start the engine/taxing.

 

I use ott and open composite.

[=IRFC=NakedSquirrel]

I've had luck by both removing the extra pilot head move controls and by making sure my headset is centered or close to center when I start the game.

 

(When I had the pilot head control on mouse, I could move the mouse and "Hear" the virtual head moving although it wouldn't move on my screen, so I think this affects what renders)

 

I've been able to spot trucks, AA, and buildings at a good distance.  HP Reverb, SteamVR

 

Is this just happening to people in MP?  Is it only certain types of ground objects?  And is it a consistent bug?

[SCG_Fenris_Wolf]

Guys, to get it fixed:

 

Do you have access to the mission in which this appeared?

 

Can you upload it please?

I will try this and see if it effects me with less "pop in" objects. Thanks for the suggestion.
Also, I shot you down in your lightning tonight on CombatBox

[SCG_Fenris_Wolf]

It is not nailed down why it happens to some, definitely not yet. Any information, especially repeatable findings that can get confirmed, are incredibly helpful!

 

Post them here it'll get forwarded, promise

Yes, it seems that low altitude has a major effect. While you are taxiing on the ground you rarely see arty, AA, or pilots next to you.

 

I can take a video of this phenomena during taxi. It is easily repeatable and  predictable. Would that help any?

[blitze]

Also guys - list out thoroughly your in game Graphics Settings and probably helpful your other VR settings i.e. SteamVR / Oculus / PiTool / Nvidia settings if not standard.

 

Details to help reproduce the issue and get it sorted.

[Beazil]

FWIW, Pimax 5K+, 90, wide fov, nvidia 2080.  High settings except canopies off.  Not seeing this issue.  Good luck sorting this out.  I have experienced something like this online with ground targets, but so far offline I've not been able to reproduce it ( a good thing).  Thanks for the videos in particular.  I hope this gets sorted for those of you with issues.   I will be mindful and post if I see it again.  S!

[Rapierarch]

Has anyone found solution for this. I have this problem like 2 years. But now since mosquito and ME-410 coming I really want to do ground attack first time in IL-2. But I cannot do it when targets disappear when I'm in range.

I see same problem has been reported since 2017. So if someone has a solution please share.

 

Any developers had a look at this? So many updates and new clouds and atmosphere but still ground units cannot be rendered correctly.  

[RedeyeStorm]

Use the key VR recenter in combination with kp5. It doesn’t solve it completely but at least they should not disappear where you are looking when in cockpit. In F2 view they still will disappear when you pan around your plane.

[-332FG-brooklynspo]

I get this and it's driving me batty - ground targets that are off-center popping in an out of existence and disappearing in zoom. Really noticed this playing on TAW recently, as emphasis is on smaller ground targets, but it happens everywhere - multiplayer, missions, quick-missions.  It almost seems like IL-2 is rendering as if I have objects (canopy struts?) in my line of sight, but obviously, I do not. Certain objects are more susceptible - arty disappears before sandbags, airfield "speedbumps" flicker off and on even when nearby....

I have a Reverb G2.  Happens both in Steam VR and OpenComposite. 

I have removed all Pilot Head Movement bindings and centered headset. I have done a fresh installation of IL-2. I have tried a ton of graphics settings.
