I dont have the means to test it for occulus unfortunately, so i can guarantee compatibility. I could though test to see if it is compatible with a scene arrangment that would work in such a setup, or maybe test it with some emulator in Unity (if one exist) ? Normally the sky rendering should work out of the box, since it is something in the background (so even if both cameras see the same would still not be an issue i gather) The volume clouds do use the camera position to calculate lighting, but not for the rendering itself, so again should work, but i cant be sure or maybe miss something. Is there any way to test this without having the actual device (a templete scene or plugin etc ?). I will check that out first and get back if i find something.
