Trying to load a object on Oculus Quest with WebXR but getting black texture

Trying to load a mesh with a texture on my webserver, it all works, but when I load it up on the quest I’m getting a black material, anyone know what the material system uses on the quest?
Can I use normals, gloss, etc?

@RaananW would likely know.

Should be working just like on your desktop/mobile. It’s an android system, using chrome internally. I doubt it’s a rendering issue (but always possible, of course). I would check network / delivery issues
