DT3D skin shader is an oren nayar based shader with at the moment 54 controllable attributes that control the subsurface scattering and the many specular layers. It has 4 functions contributing to the subsurface scattering all of which no raytracing is needed to work. Its specular layers are comprised of 8 specular calls one including a lafortune specular function with measured skin reflectance data inputed into it, so really thats 10 specular calls. Then the shader is build in a layer fashion mimicing that of real skin, I layered 3 skin layers the subdermal, dermis and epidermis.
