When I create a room which in enclosed and I use VR template and create my own level I include Post Process, Light importance Volume, Navmesh. After adding in my spotlights and building the lighting I launch on the headset which it then doesn’t seem to work the room is black and only emissive materials can be seen. The spot light doesn’t do anything whilst wearing the headset.
Make sure that spot light is static, any stationary light is not working in mobile VR, it can be movable(big performance hit) or static. If you want to use movable spot light you need to turn it on in project settings
