Now that you've released PBR maps I would like to know how to upload and assign them to Sketchfab automatically.
In the classic renderer I uploaded an obj with a mtl file.
In the mtl file the map_Kd referred to the diffuse texture, the map_bump referred to the normal map.
But how to assign the maps for e.g. the roughness, metalness, ... textures?
Thx for your help!
