:DESCRIPTION:
Brdf Scatter shader is based on the research paper "A Practical Model for Subsurface Light Transport" by Henrik Wann Jensen. The shader implements a BRDF approximation of a bssrdf as described in the research paper. As the name suggests its a BRDF and not a full BSSRDF shader. Meaning this shader is better suited for opaque surfaces that need some scattering but not a complete and slow BSSRDF. It can handle materials that look more like wax, jade, and porcelain type objects. With the right settings it can also look like other materials but won't look as good like a full BSSRDF. This shader has the same parameters as the BSSRDF, but with the important difference that the amount of diffusely reflected light is computed from the intrinsic material parameters. Use's no form of raytracing so the shader is as fast as a normal lambert depending on the shading network.
