Hello Blender Nation!
I'm not much of a character guy but someone asked me on my last tutorial if I could make a skin material. I've never tried before but with a little knowledge of procedural texturing I think I came up with a "pretty good" shader. This isn't 100% realistic, but should do a fantastic job of taking your character's skin from a basic "SSS only" material to the next level.
The end result here is a balance between shader complexity, and final result.
Please let me know what you think. I'd love to see someone take this a step further and create procedural moles, scars, and more. The possibilities are endless!
Happy Blending :)
