trying to automatically create a materialbuilder based on primAttrib(name)

[zetavfx]

Hi, let me explain the best way I can.

1.- I have multiple objects in an alembic

2.- They have name attr

3.- I want to create a material (pxrmaterialbuilder) with that name attr and have it assigned to that object with a material node

 

I am trying to do it with a python node written like this (not like this, this does´t work)

node = hou.pwd()
geo = node.geometry()

# Add code to modify contents of geo.
# Use drop down menu to select examples.
import hou
import itertools

# Define geometry node name
geometryName = 'name'

# Get scene root node
sceneRoot = hou.node('/obj/Ship/matnet1/')
# Check if "MY_GEO" exists
if hou.node('/obj/{}'.format(geometryName)) == None:
    # Create empty geometry node in scene root
    geometry = sceneRoot.createNode('pxrmaterialbuilder', run_init_scripts=False)
    # Set geometry node name
    geometry.setName(geometryName)
    # Display creation message
    hou.ui.displayMessage('{} node created!'.format(geometryName))
else:
    # Display fail message
    hou.ui.displayMessage('{} already exists in the scene'.format(geometryName))

 

Here are my questions:

 

1.- How do I pass the attr name to the pxr node?

2.- Is this the way to go?

 

thanks.
