Considering what I can see available for materials, it would be nice to include a material map, akin to standard UE fair.
Current supported maps as per the guide:
- Diffuse ( Albedo + Transparency )
- Normal ( DirectX )
- Height
What things should shift to:
- Diffuse ( Albedo + Transparency )
- Material ( Occlusion + Roughness + Metallic ) Standard UE packing.
OR ( If Emissive Is needed for a model ) - Material ( ORM + Emissive ) To include emissive masking, with a color to select, rather than have it seperate, which would only waste more resources.
- Normal ( DirectX )
- Height removed, this is more expensive than just a normal.
- Tint ( Removes the need for people to upload like a billion color variants of one model )
Additional: Lower Material Count Per Object ( Higher counts increase the time required for a frame to be created ) Geometry count can be higher considering geo can be handled quickly, its material slots and shading which will cause a lower FPS.
I am a tech artist myself, so if you need help implementing this, do let me know, I would be happy to help with the work for this, especially in optimizing it down, material wise.
