Marmoset Toolbag: Shader subroutine fields

Materials are composed of shader blocks, each block has multiple subroutine variants.

Shader blocks:

albedo
diffusion
displacement
emissive
microsurface
occlusion
reflection
reflectivity
secondaryReflection
subdivision
surface
transparency
extra

Example:

mymat = mset.findMaterial("My Existing Material")
if isinstance(mymat, mset.Material):
	# Set a specific variant for a block:
	mymat.setSubroutine("albedo", "Vertex Color")

	# Disable a shader block:
	mymat.setSubroutine("microsurface", "")
