UDK skin shader is a real-time multi-layered skin model implementation in the Unreal 3.x Engine. The shader is based on research from “Efficient Rendering of Human Skin”
, implementing most of the effects described in the paper including the multi-layered diffusion scattering in skin. Along with the multi-layered subsurface scattering the shader implements the physically based specular term to better capture the specularity of skin. This is a great shader for the artist that wants to push there characters to that next level. Also can be quite usefull for those artist using the UDK for pre-vis work.
