Unity GLTF exporter - material/textures not embedding properly(?)

Hey,

I’m running some tests with the GLTF exporter package. There seems to be an issue with the exporter or my understanding of it.

I’ll drag a simple window or door object into the scene, and when I export it, instead of a door/window appearing with appropriate materials, it appears all white.

I’ve seen some similar issues happening with FBX exporter where remapping the materials will fix the issue. I was wondering if the same is true for GLTF? Or is there another way to tackle this issue?
