Hi,

I imported my model to unreal engine 4.16 and applied materials. Everything is working in preview mode, also when i packed it for windows, everything is ok. But when i packed it for Samsung Gear VR-android -24, the surfaces and model is somehow corrupted. I attached a picture, it’s not clear since i took it from vr.  
What may be the problem?

Thanks,
