How do you upload a ugc with a PBR texture?

Ive started seeing items like this GOLDEN HOODIE [PBR] [1.0] - Roblox on the marketplace. I wondering how you upload with a pbr texture. Any answer helps!

use SurfaceAppearance and make sure its a MeshPart

UGC is different from Studio MeshParts

UGC doesn’t support PBR; you must instead bake the lighting and use it as a diffuse texture.

UGC does support PBR, if it is layered clothing or a bundle. The example shown is layered clothing. You can even see how shiny it is in the 3D preview! You have to use “Surface Appearance”
