I uploaded my project about 4 days ago, looked fine in sketchfab and was happy with it. Until I noticed something was clipping, so I fixed it, and reimported the fbx.
But it unfortunately broke my materials. Everything is extremely shiny. I tried reimporting again, and even tried deleting all of its textures, reimporting and reassigning them. I made sure my textures are on linear (roughness, metallic, etc.) Nothing gives.
How can I fix this? Seems like a reimport bug.
EDIT: Looks fine in Chrome, but crap in Firefox... I initally uploaded, and viewed it fine in Firefox, but when I did this fix, broke in firefox... I don't want any potential firefox viewer to see it and not realize it looks correct in Chrome...
