I am using URP. No Render feature. The dimming is apparent, and inverse from the rest of the camera... sort of. At first I thought it just had a negative y. Then I noticed that it also rotates about z double my rotation? It's weird. Turning off for now until it's solved but I'd really like to get it back because we have customers using it outdoors. weird segmented dimming.zip (5.9 MB)
But since it's showing up in the video and it's only some stuff, I can't help but think it's something left over in my scene from the old way of doing segmented dimming.
It's a layer thing! Only my UI layer is doing it. But also could be between the two cameras. Because actually my UI camera is rendering the UI layer. so maybe it's that camera, but I can't see any obvious setting different.
It seems that this is a known Unity issue. In order to fix this issue, you will need to upgrade to the newest version of Unity. Apologies for any inconvenience this may cause. We would love to hear back on how it goes.
