The Material LOD is not a processor or tool by itself. In the Simplygon GUI there is a Material LOD section but in the API it is not available as its own entity. The Material LOD is rather a sequence of processors and tools to bake all the scene materials to the LOD.
When a LOD is generated by any of the processors from the Processors section - a Mapping image can be generated along with it. The Mapping image can then be used to bake the original materials to the LOD.
SDK Examples:
•CastingWithTextureBlendExample
The Material LOD consists of:
•Parameterizer - To generate texture coordinates
•Chart aggregator - To generate texture coordinates
•Mapping Image - Generated from a processor to be able to cast materials
•Material Caster - To cast the materials
