In Omniverse, PBR textures work good or they need to be converted to MDL format? If yes then how to convert PBR to MDL?
PBR textures: albedo, roughness, metallic, etc can all be assigned directly to our OmniPBR and other core materials.
OmniPBR has as inputs:
Albedo Map
Roughness Map
Metallic Map
ORM Map (Occlusion Roughness Metallic)
Emissive Color Map
Opacity Map
Normal Map
