I seem to be having problems with my current project and the solutions posted before either aren't working or aren't available. Setting the far clipping plane on my cameras has no effect. Previous solutions were to apply the changes to the prefab. This had no effect. Another solution was to change the far clipping plan on the OVRCameraRig script. That option is no longer available. Is the far clip plane hardcoded on the Quest 2 and I'm just spinning my gears?
You have to enable "Use Per Eye Camera" in the OVRCameraRig script.
After you enable this flag, the disabled camera-components of the LeftEyeAnchor- and RightEyeAnchor-GameObject will be enabled and you can set the near/far clipping planes as well as other camera settings.
