Fur pelt from strands along a flow field

Generate tileable PBR maps of animal fur: thousands of tapered strands combed along a smooth flow field, gathered into locks, with banded hairs and coat patterns (solid, tabby stripes, spots or rosettes). Use for creature and animal skins, fur trims, rugs, plush toys and stylized characters.

Limits to consider

Fur is painted as flat strands in a height field, so it reads as fur lying flat seen from above; it is not hair geometry, cards or shells, and it has no silhouette fuzz, anisotropic hair shading or translucency. Strands are three straight segments each, so long fur looks combed rather than tangled. Coat patterns are stylized periodic fields (stripes, spots, rings), not species markings. Strands are drawn at least about a pixel wide, so the strand count drops at small sizes. Occlusion is a blurred-height estimate.
