This geometry node setup converts grooms created with Blender's hair system into alpha cards or tubes, optimizing them for low-poly game assets or animation workflows. The tool works by snapping unwrapped, premade alpha cards to proxy cards generated from the hair curves, which allows for the use of texture atlases. It includes five distinct node groups for generating card and tube instances, converting curves to proxies, and creating shader masks from vertex groups.

The system requires the premade cards to match the shape, point count, and indices of the proxies to function correctly. Alongside the node groups, the project file includes a stylized hair card material and three basic texture atlases designed for hair and hand-painted feathers.
