I opened the Unreal Editor VR example, imported the TwinMotion materials and set the floor to a nice parquet. In the editor it looks like this:
However when I run it on my Oculus Quest it looks like this:
It's a little hard to see in this example because of the weird artefact on the floor, but the reflections are much lower quality. It seems like the bump maps aren't being used at all.
Is there any way to fix that? (Bonus points if you can tell me what is going on with the grey overlay, which doesn't show up in the preview.)
