Diffuse/Roughness/Metalness confusion !?

jblake · Nov 2018

Hey guys, I'm relatively new with PBR workflow so that's why I'm asking, please bear with be.

I have a request from somebody to do a 3D model + texturing, using Diffuse/Roughness/Metalness maps. Question is if this is PBR workflow?

I thought it must be something more like Albedo instead of Diffuse. Didn't say anything about Normal maps or AO map also. Is it possible to make a decent model only with the first mentioned maps? Polycount is pretty decent, around 25000 tris.

Thank you

They mean all the channels but using metal/rough rather than spec/gloss

You should read the PBR guide on Allegorithmic site: https://www.allegorithmic.com/pbr-guide

I think EarthQuake's intro is a bit more artist-friendly.

+1 for EarthQuakes articles and the many tutorials at marmoset. When I read the jargon heavy PBR stuff, my eyes cross and I begin to drool. When I read the artist-focused stuff at marmoset, +10 intelligence immediately.

But I really wanted to say to OP, don't just try to read all this stuff and understand it completely. Make art first, and then it becomes much more clear. It sounds way more complex than it usually is (well, for practical applications anyway.)
