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
Does anyone have examples of a PBR object or scene with and without a GI environment I could point some people to? I can't find the right terminology for Google.
