Blender geometry nodes - Hair cards from curves

This geometry nodes setup makes the process of creating hair cards for games and realtime rendering a lot easier.

The user inputs the following into the geometry nodes setup:

• A set of hair curves
• A set of hair cards
• A surface (a head)

and the geometry nodes setup creates hair cards that are deformed along the hair curves and align their twist to the surface geometry. A tutorial can be found here:
