I wrote this script to speed up the process of assigning textures and set the materials in Marmoset according to the project I worked, with just a click.

This script finds the assigned materials and texture-files of a model and creates a materialfile (.tbmat) for each one to use in Marmoset Toolbag. The materials already have all the predefined settings for marmoset we had in our project, so no additional adjustments were necessary.

---

The .tbmat definitions for all kind of different texture/materials for the project are stored in a separated file as string, which are read in and combined into the final .tbmat file.

Here’s a part of how the parameters for different channels with textures are defined:

		ParAlbedo = "
			@Sub SRAlbedo = SRAlbedoMap
				Albedo Map = "+LineAlb +"
				Color = 1 1 1
			@End
			"
		ParNormal = "
			@Sub SRSurface = SRSurfaceNormalMap
				Normal Map = "+LineNrm +"
				Scale & Bias = 1
				Flip X = 0
				Flip Y = 1
				Flip Z = 0
				Object Space = 0
			@End
			"
		ParRough = "
			@Sub SRMicrosurface = SRMicrosurfaceGlossMap
				Gloss Map =  "+LinePar +"
				Channel = 0
				Gloss = 1
				Horizon Smoothing = 0.5
				Invert = 1
			@End
			"
		ParMetal = "
			@Sub SRReflectivity = SRReflectivityMetalnessMap
				Metalness Map = "+LinePar +"
				Channel = 1
				Metalness = 1
				Invert = 0
			@End
			"
	
		ParAO = "	
			@Sub SROcclusion = SROcclusionMap
				Occlusion Map = " +LinePar +"
				Channel;occlusion = 2
				Occlusion = 1
				UV Set = 0
				Vertex Channel = 0
				Cavity Map = nil
				Channel;cavity = 2
				Diffuse Cavity = 1
				Specular Cavity = 1
			@End
