# Getting started
The Houdini plugin consist of a set of SOP nodes which can be used to optimize geometry.
All Simplygon nodes only support triangulated geometry.
You access the Simplygon nodes from the geometry tab menu.
# Reduction
The reduction node removes triangles based on the specified triangle ratio.
# Customization
To customize a node you have full access to the Python implementation via the Operator Type Properties (opens new window).
