If you have environment reflections to anything other than off, turning your head in the cockpit of the Cadillac DPi makes the environment reflections flicker on and off depending on view angle. If I can figure out how to get a screenshot in vr working I'll post them below Dave
I've not got a VR shot but here's 2 shots from a flat screen, one with Environment reflections on and the other off When in VR with reflections on you get a flickering between effects in the 2 screenshots
Got that error in dev mode when I'm working with materials. It's always flickering from various angles when the material doesn't have reflection map or having enviroment map as reflection in material json-file (only REFMAP0 working well). Maybe it will help solve the problem because I don't like to set REFMAP0 to interior materials.
