Do you need help rendering Xgen hair?

 

PxrMarschner Hair

PxrMarschner is a material designed to render realistic hair, fur, and fibers.

This is the same material and design used in many of Pixar's animated features provided to users rendering their own scenes. The controls are minimal and artist friendly. The material is also physically plausible so that artists can begin with a realistic result and refine their options based on art direction.

If you would like to dive into the technical details of the material you can see the Pixar Technical Memo 15-02 "A Data-Driven Light Scattering Model for Hair" by Leonid Pekelis, Christophe Hery, Ryusuke Villemin, Junyi Ling for more information. This document will describe the parameters with examples so that artists can begin creating immediately!

If you would like to follow along, you can download the example Autodesk Maya scene file using Xgen hair. This scene requires Maya 2016 SP5 and above and the latest RenderMan installation. Avoid renaming items as this may cause Xgen to fail to export hair.
