The only material on this version of Sam is the basic cell turbulence displacement, SSS is 2.6, 1.7, 1.12, specularity is controlled by two decals (Spec size and Spec intensity) and all skin color is a decal which comes from a painted Krita image file where the layers can be adjusted or exported individually (each layer painted in 3DPainter, then adjusted in Krita). The backlit image is two back lights, the lit image is the same two back lights with an additional key light (not the best lighting...needs adjustment) and the animation is a single light spun around Sam over two seconds. I still need to add the wrinkles (maybe eyelashes), but I thought it wasn't a bad set of test renders.
