Refactored my implementation for Artistic Friendly Marschner to RSL 2.0 format. Still have no free time to accomplish my multiple scattering stuff for hair. Just rendered two samples according the real photo, sorry for my poor artistic creativity. Code is here http://ortholab.codeplex.com/SourceControl/list/changesets.
There is a post in the forum of 3delight, http://www.3delight.com/en/modules/PunBB/viewtopic.php?id=3379, about my shader.
