Ok, so I often hear people talking about simulating or faking the quite complex qualities of human skin. In this tread I want to uncover as many thoughts and opinions as possible in this area. I am no expert in the field of texturing but I really love learning new techniques. I’m all for sharing, so attach your material, a pic of it in action and a note about how you made it. This isn’t program specific (as in post stuff from any program) so I hope everyone can get something out of this thread.

I’ve been working on a procedural based skin for a few hours here and there, and have come up with the following. It is quite simple and basically uses a strong hi-light for extreme angles (to simulate the oily sheen) and a soft dull one for lower angles. While several fall-off maps bring life into the troublesome areas in the shadows and dark areas in the diffuse, extra lighting and translucency channels. It was created in MAX 4.2 with a raytrace material.

That's a great looking texture colour-wise, but the bump grain is too large :)

Here's a tutorial on human skin shading, it isn't step by step but should help you in some areas.

I love that texture, I had to edit a bit, turn of some of the texture maps becaus I did not understand what they do. I dont think it looks very human but dam cool...

Leigh: Thanks, the bump is something I'll be concentrating on getting right in future attempts :) ...Leigh, are you planning on posting a skin :)

Luddy: I studied that tut about a month ago, I would love to know half as much as Stahlberg does...then I'd be set.

Cheers

Well, I downloaded that thing, slapped it on my HC head mesh, and fiddled with it a bit-- does this look any better? It seems too yellow to me on the left, but if I change it any it looks too dark, or washes out to white. I'm running in circles clueless as to how to improve it. Skin is darn hard!! :scream:
