Pure PBR assetes
We mark as pure PBR assets which:
- have these material properties
- use only principled shader in cycles
- the inputs of the principled shader are texture images or unplugged
- don't use any procedural textures
- use UV or Cube mapping.
- and their geometry
- has optimized mesh density
- only use these modifiers: Subsurf, Edgesplit, Displace
The advantage of pure PBR assets is their convertability into almost any game or render engine.
Pure PBR isn't a limit, and we expect and understand many assets require overstepping these limits (like our mascot kitten).
