Hey that actually looks pretty good! Nice job.

Thanks, thats pretty much as far as I can take my simple diffuse/absorption shader.
But in the end, when your light is good, your skin will also look good. And lighting in closed
interiors is still a big challenge for me. I'm trying to get better all the time

Here is a half body render I did. Figured I should probably show how most of the skin looks on the body. I dont know if I like the included roughness maps. They appear to just be lightened black and white diffuse maps with some dark added to certain areas, though I dont know if that's how a roughness map for skin is supposed to be made.

I think most roughness maps are derived from the specular map, sometimes they are just inverted. The problem with spec/roughness maps is that they are made with Iray in mind and need a lot of tweaking to look alright. I try to avoid using them alltogether and break up the specularity through the bump/normal map and micro bumps. The specularity on your model looks pretty nice tho.

Do you use texture maps for the sclera and eyes or just a color? Do you mind sharing the random walk depth settings for these?

I can't exactly recall everything right now I can send you a .duf with the materials when I get home from work.

Thanks, that would be neat, I like comparing my shaders to see how other people go about it.
