Mesh Hair Groom is a Geometry Nodes setup that allows users to create and edit hair shapes using standard 3D modeling workflows in Blender. It integrates with building-in hair groom modifiers and supports cloth simulation for adding dynamic hair motion.

The system includes support for vertex color painting, UV position attributes for applying images, and weight painting to control parameters across node graphs. It provides tools for positioning hair to bake textures when creating custom hair cards, and it outputs full material attributes for hair rendering. The package includes an example scene, utility nodetrees for UV management, a video tutorial, and written documentation.
