Initial Skin Results

This weekend I got some free time to add subsurface diffusion to the skin shader.

Right now I have both the specular and subsurface diffusion working. The images below show a comparison between a simple lighting shader and the current skin shader. Because the diffusion effect works in image space there’s some issues at UV seams and unnatural darkness at small UV regions with large shadow areas closeby.

The next step is to use a stretch texture to help reduce image-space filtering artifacts.
