I know it's ironic that I'm going from real time rendering to offline rendering but it's the only way to pass one of my school's courses.
I basically know how to make my materials in UE4 (Base color, Metalness, Roughness, Normals and AO) but I'm sort of confused how to bring that over into Mental Ray, especially for Arch and Design materials. What kind of precautions/differences should I look out for?
