The Extended Projected Materials Framework can be used to add additional LOD material objects to the four hard-coded snow and ash LOD material objects in the game engine. See Snow/Ash LOD Shader for more explanations.
DynDOLOD supports the additional LOD material objects that are defined in the *.JSON files for XMPF, so that the generated object LOD meshes *.BTO instructs the game engine to make use of them.
