    This is part two of a two part tutorial that shows in detail how to set up wavelength dependent scatter in a shader network using fast_skin_maya SSS shaders in Maya 2012 and earlier. Newer versions of Maya have this built into the misss_fast_shader2 shader, but it is good to understand how and why this is important. Also shows how to break the Red, Green, and Blue wavelengths of scattered light out to AOV render passes for comping in Nuke. All with Final Gather, Linear Color Workflow, and the great headscan from Lee Perry-Smith at Infinite-Realities.

      This is part one of a two part tutorial that shows in detail how to set up a human skin shader in Maya with Mental Ray. The shader network we build here has wavelength dependent scatter to make human skin red color bleed. By allowing the Red channel of Subsurface Scatter to be much stronger and scatter deeper, the resulting renders have a red edges on the shadow and thin back lit areas. This is for Maya 2012 and earlier because in newer Maya 2013 they have included this feature in misss_fast_shader2 phenomenon as RGB breakouts in front and back radius. Still it is good to know why we tint the radius and how to break SSS out into render passes. Big thanks and all credit to the free headscan from Lee Perry-Smith at Infinite-Realities.
