Shadow Generations Standard Shader Behaviors

The majority of all shadow generations shaders make use of "shader models", which loosely determine how a shader interacts with lighting or more.

Index	Name	Description
0	Clear	Technically, this is the "no shader model" shader model, and so far no shader has been discovered that uses it. It is used to determine where to draw the skybox
1	Unlit	These shaders do no interact with lighting at all, but just render out the emission channel and use that as is. These shaders allow for custom lighting behavior.
2	Standard (PBR)	The "default" shading model, which is used by the majority of all material shaders. It uses the standard physically based rendering lighting model.
3	Subsurface Scattering (PBR)	Identical to the standard PBR model, with added subsurface scattering lighting.
4	Anisotropic Reflections (PBR)	Identical to the standard PBR model, with one exception: Reflections are rendered using with anisotropic distribution. The left model uses standard reflections, while the model one the right uses anisotropic reflections
