Question Camera.SetStereoViewMatrix not working (2020+)

I wanted to upgrade my project from 2019.4 (Virtual Reality Supported tick) to 2020.3 with XR Plugin Management (tested both Oculus and OpenXR). I was using Camera.SetStereoViewMatrix function to rotate cameras for each eye in addition to headset movement. Now using it does not change anything and also stereoEnabled on main camera returns false. I'm using URP and XR Interaction Toolkit.

I set up a fresh project with just an XR Rig on the demo scene with a script from here https://docs.unity3d.com/ScriptReference/Camera.SetStereoViewMatrix.html and it didn't work either (also tested on 2021.1.3).

Is there any way to do this or should I stick with the older version of Unity for now?

 

This also seems to be related to this post: https://forum.unity.com/threads/stereoenabled-false-in-unity-2020-3.1098265/#post-7085584
After upgading to Unity 2020.3.4 stereoEnabled is always false.

Though, there is no solution yet.

 

Is there a solution, 6 months later?

Seems like a coding problem unity side because StereoEnabled = false on the camera being used to render AND cam.stereoActiveEye also always = MONO.

 

I'm also wondering why there seems to be no easy way to set camera.stereoEnabled..
Even after converting the main camera to an "XR Rig" with the following 2 packages, it's still always false:

"com.unity.xr.management": "4.2.1",
"com.unity.xr.openxr": "1.2.8"



Kind of confused how to get stereo double-wide rendering working. (Note that I've never done VR development before, so maybe this is obvious?)
