Here's some work on the Skin shader I've been working on. I didn't do any of the actual art here, just the shader creation. The model and textures were built by Chi Han an artist I"m working with here. I've just finished documenting the shader for graphic programmers to implement. Also trying to get some resources so we can see just how good we can make this shader look with some more final touches on the art.
We haven't used sub surface scattering on this as it sounds like it'll be way too expensive for what we'll be using it for.
The shader though is able to blend between dry and wet skin ( 2 different specular maps). We can also animate facial wrinkles with it by mask blending in another normal map.
