Patch chunks are used to make up high level surfaces. For example, triangle patches can be used to make a mesh.

General information about mdl materials.
A material can be defined as an aggregate of "lobes". Each lobe will be evaluated or sampled, and the results added together. To do this, use the Aggregate material chunk (smAgg) or the Aggregate material chunk with subsurface scattering (slpm) including an arbitrary number (at least one) of the chunks defined below.
The folowing are optional chungs that modify surface appearance in some way.
