HI all, I am attempting to build a UI using OVROverlay in Unity. It looks great BUT on mobile the overlay renders in front of any scene geometry, thus occluding the controller models and pointer rays. The same behavior can be observed in the OVROverlay scene in SampleFramework. A message in Player Settings indicates that the shared depth buffer is not available on mobile, so I am thinking it might be a limitation.
However, the Oculus Home scene and video player apps don't have this issue.
