Thanks visionmaster!
Just wondering if its quite a tough job coming up with these kind of shaders, i remember Maxwell wasn’t for the faint hearted
Hm, for me it’s the other way around. In Fry (and Maxwell) you have 0° and 90° Ref-Color, ND and Roughness. That’s it (mainly). Only the few parameters in Reality exist.
I’m trying to compare it with going to a point from inside or outside.
A biased engine calculates an approximation to what something should look like, while a unbiased engine simulates what something looks like accurately. Or more simple:
biased = what it looks like / unbiased = what it is
So, handling an unbiased engine is pretty easy (in my eyes?) … -
maybe after turning the point of view.
I hope, that was understandable, english is not my native language 









I have tried to use zapplink with a big document size (about 6000x4000) , because I have very good textures and I want keep all details . Now I am planning to make alpha brushes from these hq textures and add all details in brush and then polypaint my model . I ll show you my end result if I will success
