HairGen provides a procedural system for generating stylized hair inside Blender. Built entirely as a geometry nodes modifier, it gives users parametric control over the shape and structure of individual hair strands for character grooming.

The tool exposes multiple variables to customize the geometry output directly from the modifiers panel. It also generates and passes attributes that can be accessed within the Shader Editor to drive custom material effects on the stylized hair. Additional features include root snapping to align strands with character meshes and geometry smoothing capabilities.
