Bug Failed upgrade to 2021.3.1f1 LTS, looking for suggestions please

Hi,

Project was working fine, upgraded from 2021.1.16f1 to 2021.3.1f1, runs fine in Unity but when I Build the APK file then try to load while in my Q2 headset I get a black screen. I get the 3 loading dots, then a pure black screen then an exit with no visuals or error messages.

Stuff I’ve tried to far:

• Changed from Gamma to Linear and deleted Vulkan (when it first converted it asked to change Gamma settings, to use Vulkan)
• Changed from MultiPass to Multiview
• Uncheck all the following in Android build area

o Low Overhead Mode
o Optimize Buffer Discards
o Phase Sync
o Symmetric Projection
o Subsampled Layout

Game Builds with no errors.

Any ideas or suggestions on what to try or do next?

Thanks,

Vanz

Ps. Had following Build error message upon conversion = “BuildFailedException: Only Linear Color Space is supported when using OpenGLES. Please set Color Space to Linear in Player Settings, or switch to Vulkan.”

I Switched to Vulkan and it Built okay with no errors

 

Upgrade Oculus xr plugin AND oculus integration to the latest version, then it should work again.

For VR I always recommend using linear color space btw, might want to use that.
GLES3 can have better performance (unless you want to use late latching or spacewarp)
Edit: nvm, you already did the last thing. The first bit should fix it tho

 

Same issue here 2021.3.1 is broken for VR but it works fine with 2021.3.0

 

Same here. My project was working fine in Unity 2021.2.14f1 and while porting I have a black screen.

I tried with an empty new project set with URP and the problem is the same.
Current unusual settings :
- Gamma color space with auto graphics API (hence Vulkan).
- Min API Level 24
- .Net Framework (hence 4x.)
Tested both with Mono and IL2CPP

Just to be clear, the build is going through without any issues but the app crash when opened in the Oculus Quest 2. Everything is fine in editor.

Here are the errors from Oculus Developer Hub.

 

Perhaps time to file a bug report?
https://unity3d.com/unity/qa/bug-reporting

 

Getting this issue as well in 2021.3.1f1.

Switching from Vulkan to OpenGLES3 'fixed' it. But looks like Vulkan got broken in the recent builds of Unity.

 

Did you upgrade the unity integration asset as well?

 

I did, to v39

Even tried on a new fresh project using the URP Template and had the same results.

 

Then some settings are wrong. I have no issue with unity 2021 for quest. Did you follow the developers guide?

 

It is only a problem with Vulkan, switching to OpenGLES3 and it works just fine.

adb logcat just shows a Crash as soon as I switch to Vulkan.

Have you tried disabling either Symmetric Projection or Subsampled Layout? Based on my testing the bug is caused by enabling both of them.

 

Yes, everything is disabled.

I tried this project as well: https://github.com/nukadelic/unity-application-spacewarp/

Same issue

 

I am having similar issues on Unity 2022.1.7. If either color space is set to Gamma or High Dynamic Range is checked in URP then a Vulkan build on the Quest 2 results in an instant crash or gets stuck on the 3 dot loading screen.
