Here is my new artwork. Wanted to make him look like a crazy wishing man, ravenous for gold.
based on sketch by Jean-Baptiste Monge . Modeling, sculpting, shading, compose and video editing done in blender, textures done in Substance painter. Render Cycles.
I will duplicate my answer in wip here :
Here is material of skin. Nothing complex.
Color of the sss radius I took from Pixar Radarman wiki, and maybe adjusted it a little bit.
In my experiments the value of sss radius is around 0.12 in blender( for real scene scale ). If you have scale of the character like 5 cm (not 180 cm), value will be different. I did photo of my self with strong light behind my ears, and I do the same in blender with my characters, then I try to much the strength of the sss from photo and render. It will help if your character is different scale from real.
The most important is Albedo texture , I painted it in Substance Painter by hand ( I don’t like projections, painting it by my self is more creative).
Value of roughness is around 0.4 , but it different for different parts and have cavity map on top.
