Python geometry node in Blender Geometry Nodes

Runs a Python snippet to modify the incoming geometry.

This node is designed to modify the input geometry. 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.
