Textures black in Quest, but not on desktop?

[paulmelis]

Hi, I was testing a room (not made by me) which renders fine when viewing through Firefox on my desktop PC. But when I view the same room on a Quest in either Oculus Browser or Firefox Reality the textures in the 3D model all show black. I haven't experienced this issue before, as other rooms work with no problems on the Quest. Any clues what properties of this particular scene might cause this issue?

Edit: I do see some issues in this repo referring to black textures, but not for this particular case

It seems to be due to use occlusionTexture in the glb. Removing that brings back textures when viewed in the Quest
