Bug Oculus - Single-Pass Render to Texture (Array) - 2nd slice is always empty

Hello,

After 2 days I tried all possible solutions and engine versions and I just can't get it to work - the 2nd slice is always empty.

In VR SinglePass Stereo rendering the output is made to TextureArray with 2 slices. The main camera has 2 slices rendered correctly (I can see the RT in OnRenderImage), but the camera with custom RenderTexture always renders to 1st or 2nd slice.

What I tried:

Texture is based on eyeTextDesc:

Code (CSharp):

1. RenderTextureDescriptor descript = UnityEngine.XR.XRSettings.eyeTextureDesc;
2. descript.vrUsage = VRTextureUsage.TwoEyes;
3. descript.volumeDepth = 2;

Rendering is made in the 'OnPreRender' call from MainCamera (this makes the output with distortion mesh, but still only one slice)

I am setting buffers for camera:

Code (CSharp):

1.  
2. renderCamera.SetTargetBuffers(rtColor.colorBuffer, rtDepth.depthBuffer);;

and also trying to tell Graphics to bind 2 slices (by the last parameter -1) but it still won't do that ( it detects if I pass 0 or 1 as an argument to render to 1st or 2nd slice but never both for -1)

Code (CSharp):

1. Graphics.SetRenderTarget(rtColor,  0, CubemapFace.Unknown, -1);;

Render Camera is configured to render both eyes

I really don't want to make 2 separate passes for left/right eye so any help will be truly appreciated.

There is thread for using command buffers:
https://forum.unity.com/threads/com...s-instanced-renders-only-to-left-eye.1026310/

but I need to render the whole scene to target texture (not just copy the orginal one, because I need to render custom objects with this pass)

 

any luck

 

I don't think it is supported in any way (I tried every possibility)

 

Ahh thanks, yeah I found some other stuff saying similar. If I remember correct.

 

I was able to render single passed instanced to both eyes using the CommandBuffer API, maybe you could try that

 

ooh interesting, thanks, not sure when i will get ack to that though
