Python - Add Render Properties

[garf]

Heya,

I want to expose/add this property to my geometry node via python. Anyone know what's needed to do this?

Just simply setting it's value (i.e. "1")  via python doesn't work unless it is exposed.

OK - I've got it thanks.

 

import hou

sel = hou.selectedNodes()

for s in sel:    
    group = s.parmTemplateGroup()
    folder = hou.FolderParmTemplate("folder", "myFolder")
    folder.addParmTemplate(hou.ToggleParmTemplate("vm_volumenormal", "Compute Normals for Volumes", 1))
    group.append(folder)
    s.setParmTemplateGroup(group)
