A Marmoset Toolbag plugin showcasing how to design a custom importer for the baker.

custom-baker-importer.py

import mset
 
# Create a new BakerObject
baker = mset.BakerObject()
 
# Import model
myMesh = mset.importModel("E:/MyMesh.fbx")
 
# Traverse myMesh and find objects I want to be "High" or "Low"
bakerDict = {}
 
def traverseMesh(o):
	if isinstance(o, mset.MeshObject):
		if "_low" in o.name:
			key = o.name.replace("_low", "").lower()
			if key in bakerDict:
				bakerDict[key]["low"] = o
			else:
				bakerDict[key] = {"low": o, "high": None}
		if "_high" in o.name:
			key = o.name.replace("_high", "").lower()
			if key in bakerDict:
				bakerDict[key]["high"] = o
			else:
				bakerDict[key] = {"low": None, "high": o}
	for obj in o.getChildren():
		traverseMesh(obj)
 
# Traverse the imported mesh file
traverseMesh(myMesh)
 
# Convert bakerDict to baker scene hierarchy
for key in bakerDict.keys():
	if bakerDict[key]["low"] != None and bakerDict[key]["high"] != None:
		curGroup = None
		for child in baker.getChildren():
			if key in child.name.lower():
				curGroup = child
		if curGroup == None:
			curGroup = baker.addGroup(key)
		for gc in curGroup.getChildren():
			if gc.name == "Low":
				bakerDict[key]["low"].parent = gc
			if gc.name == "High":
				bakerDict[key]["high"].parent = gc
 
# Done adding model, now we can bake
baker.bake()
