A while back, 3D Coat added the ability to use PBR shaders in the Sculpt Workspace. Although not intended as a replacement for smart materials in 3D Coat, the new Physical Shaders offer a great way to use GGX lighting and physically based rendering on high polling voxel sculpts in 3D Coat.

The new PBR Shaders include a new skin shader that can render true SSS in the render workspace of 3D Coat. The tutorial walks through some of the many shader options in the panel, and shows how you can change default shaders or make your own shaders when working.
