This node is designed to modify the input geometry of KineFX rigs. If you just want to run a script whenever the network cooks, see the Script SOP.
This node lets you modify geometry in a network using a quick ad-hoc script. To create a new, reusable geometry node type using python, see creating a geometry SOP with Python.
See editing geometry using python for information on how to write the script.
The name of the viewer state to use with the node.
Python code should modify the incoming geometry. You can use the kinefx.rigapi Python module to simplify operations on the rig topology.
Pre-compute local transforms on input and ensure the local transforms are converted back to world transforms.
