Haircard test with 1k maps in Blender v4.3, EEVEE.
Curves with geoNodes-generated unwrapped geometry are placed by hand.
Shading uses fake anisotropy effect based on "Flow" and "Noise" maps. Effect set to emission output + reacts only to view angle, but not light.
Color and Roughness constructed from the rest of the maps.
Destructively, AO baked to second UV map after the hair is finished.
