Hi Artyom - Your code here and in Dropbox was very helpful. I am trying to put a video material on an external USDZ object that I have found online and converted. But the material does not show up (the video plays - I can hear it) and I suspect that it is a faulty UV or normal map. I have found code that works with someone else's USDZ created in Blender. I am trying to simulate a planetarium, projecting into the underside of a hemisphere. I have tried every culling setting in Xcode. Do you have any ideas on what I should try now? Thanks!
