Here's some more info on the matter: This all material aspect thing depends on the shader used to render the model. If i take you a screen from SBPainter, one from Tennogen and another one from this rendering rig i'm using you're goint to see 3 different materials for everything. The problem is how's the shader written, they all blend materials and masks and they all reflect lights and generate shadows differently depending on how's the shader code written.
The only way for me to make a good material rendering is to make a first pass, put it in the actual game to see how it looks like and then make a second pass to tweak the materials where needed. Of course i'm not allowed to do that, i don't have access to any special DE Evo Engine build and i don't have internal material charts so i'm trying to make the best i can with what i have but you're not going to see a perfect result in my screenshots. As for now this should work good inside the game, i hope i'll have a chance to make that second pass if it's needed once and if this gets accepted.

One thing to be sure of is that i'm not going to be happy with an "almost good" job.
