This Geometry Nodes setup provides a workflow for simulating Blender's hair curves using proxy meshes and the built-in cloth simulation engine. It includes specific node groups like Follow Proxy, Create Root Group, and Hair Proxy to Tubes, which help link guide curves to proxy geometry. The system ensures that vertex counts and indices align precisely between the curves and the proxy meshes, allowing users to drive hair movement through cloth physics applied to extruded planes or tube-shaped cages.
