shop_materialpath from attribute

[bonassus]

 

I have become aware of an awesome script that generates redshift materials from a shop_materialpath attribute. This makes importing FBX files much more manageable. 

big thanks to kaiserlicht!

 Currently it assigns a random color to the diffuse_color channel. Unfortunately i'm not very sophisticated with my python scripting. I wonder if there is a way to get the color from from the geometries material  and assign it to the diffuse_color channel. Or even better, if it could get the texture paths and assign them to a rs texture. I though I would post this here in hopes that a python genius on here might have the answer to share. 

here is the script

import hou
import random
import re
def main():

	sel = hou.selectedNodes()
	if sel:
		node = hou.selectedNodes()[0]
		if node.type().category() == hou.sopNodeTypeCategory():

			if node.geometry().findPrimAttrib('shop_materialpath'):

				shop_materialpath_atrr = node.geometry().primStringAttribValues('shop_materialpath')
				materials =  list(set(shop_materialpath_atrr))

				# Get the last Part and remove empty Materials
				materials = [x for x in materials if x !=""]

				matnet = node.parent().createNode('matnet',node_name="matnet",run_init_scripts=False)

	 	 	
		 	 	materialNode = node.parent().createNode('material')
		 	 	materialNode.setFirstInput(node)
		 	 	materialNode.setDisplayFlag(True)
				materialNode.setRenderFlag(True)

		 	 	materialNode.moveToGoodPosition()


	 	 		materialNode.parm('num_materials').set(len(materials))
	 	 		for i in xrange(len(materials)):

	 	 			matname = materials[i].rsplit("/", 1)
	 	 			if len(matname)>1:
	 	 				matname = matname[1]
 	 				else:
 	 					matname = matname[0]


 					matname = re.sub('[^a-zA-Z0-9-_*.]', '_', matname)
	 	 			
					# Create and Connect RS Material Builder
				 	redshift_vopnet = matnet.createNode('redshift_vopnet',node_name=matname,run_init_scripts=True)
				 	rsmaterial = redshift_vopnet.createNode('redshift::Material')
				 	rsroot = hou.node(str(redshift_vopnet.path())+"/redshift_material1")
				 	rsroot.setFirstInput(rsmaterial)

	 	 			# add random diffuse value
 	 				color = [0,0,0]

 	 				for j in xrange(len(color)):
 	 					color[j] = random.uniform(0.3,1)
	 	 			rsmaterial.parmTuple('diffuse_color').set(color)



	 	 			redshift_vopnet.moveToGoodPosition()

	 	 			materialNode.parm('group'+str(i+1)).set("@shop_materialpath="+str(materials[i]))

	 	 			materialNode.parm('shop_materialpath'+str(i+1)).set("../"+matnet.name()+"/"+redshift_vopnet.name())



main()
