VR single pass instance URP Post processing only blocks out one ye

Unity Engine

I have two cameras.

  • Base Camera (Everything but UI)
  • Overlay Camera(UI)

If I check post processing check box on the base camera it only draw right eye, left eye is a white/gray.
If I check post processing check box on the overlay camera it works fine as far as drawing goes (I see both eyes) but then post processing gets applied to UI also.

Am I doing something wrong or is this a bug? Thanks!

Edit: I forgot to mention that this is a camera stack, UI Camera is stacked in the base Camera.

Iā€™m having a similar issue (Windows Directx 11, Android OpenGLES3) where the left eye is gray (but has the overlay elements), the right eye is totally fine and has the correct overlay.

This is definitely a bug. Please report this bug along with me, and maybe they will attempt to fix this. Thereā€™s also another bug where the overlay camera will disappear completely on an android oculus quest build

I have the same problem! Gray in left eye, everything correct in right. Glad to see someone else suffering with me. Where do we report this?

see thisā€¦ I havenā€™t had the time to read it yet but this was posted by some one from Unity today:

As usual when Unity staff post anything, itā€™s utterly useless. Itā€™s a conversation that ended on July 28 about a commit that either never made it into URP production, or just wasnā€™t tested at all and didnā€™t fix the issue.

If it were merged and done properly, there wouldnā€™t be people complaining about this ghastly engine-breaking catastrophe in September.

Same problem here, having the overlay camera breaks it and the left eye is grey. The postprocessing on the main camera has to be disabled in order for the left eye to render correctly

Hey there,

After speaking to the team we believe the issues reported in this thread are related to this known issue (Unity Issue Tracker - [XR][URP] Game View is grey when using Camera Stacking and enabling Post Processing). That issue is now fixed in URP 7.5 (2019 LTS) and URP 8.3 (2020.1). Please update to these versions when they become fully available.
