Weird Geometry Artefacts

Hi guys,

I’m trying to export a project for Oculus Quest and I’m getting some weird artefacts and missing textures. I attached a screen shot of what I’m getting.
I exported the same project to Oculus rift without problems, the artefacts do not show.
Does anyone have any suggestion as to why these are happening or to point me to some documentation that can help me resolve the issue?
