Like the title mention, I can't find no way to make OVROverlay to work in any scene on the quest. Everything is working perfectly in editor through link.
I'm using Unity v2019.3.9f1, Oculus Utilities v1.52.0, OVRPlugin v1.52.0, SDK v1.52.0, Oculus XR Plugin 1.4.3 and Unity Integration 20.0.
At first I tried building OVROverlay sample scene (with and without "Protected Context" from XR settings) without success. While this is working in editor and don't show any error in build, I'm currently out of solutions. Can you think of anything else ?
This could come from this option that is no longer available : "For Oculus Quest: To enable support on Oculus Quest you must also render the OVROverlay layer as an External Surface and select Protected Content in Player Settings > Virtual Reality > Oculus."
OVROverlay layer as an External Surface ? What is this ?
