if you don't mind a suggestion, I think that first image (cat on left) which has flatter colors might be better than PBR and semi realism just because it will look more artistic and avoid that plastic toy look that PBR always has (unless it's like top end realism). it would probably be faster to make the models too and…
PBR are render guidelines to assure that rendering looks the same across platforms that incorporate PBR workflows. BRDF on the other hand is an algorithm that calculates light. PBR render engines use the BRDF algorithm to calculate light. From PBR's wikipedia: "PBR topics that deal with surfaces often rely on a simplified…
Damn, this is looking great! Can you tell me, where do you get your PBR valuse for albedo/reflectivity, etc ? Im trying to approach into PBR, and Im looking for global chart of PBR values. Where did you get yours ?
Continuing what sltrOlsson said, it doesn't look like you understand the PBR workflow. Check out these posts on Marmoset's website, as well as the reference links they post. http://www.marmoset.co/toolbag/learn/pbr-theory http://www.marmoset.co/toolbag/learn/pbr-practice
