Final Processing

BW Preview

I used Texturingxyz's basecolor.

I used red green and blue channels in zbrush for bump map. And used blue channel for normal map (baked).

I used blue channel for specular map. And I'm making some changes.

I used red channel for roughness map. And I'm making some changes.

I used basecolor map for SSS map. I'm saturating the map a little. And I'm making some changes.

Each color represents a different set.
