Hair.component

Puts a groom on an entity that draws a mesh: strands grown over that mesh's surface, lit by the engine's fibre highlights.

The fields are the groom — change one and the strands are rebuilt from it, and they persist with the scene. regionMin is the field that turns a whole-body fur coat into hair on a scalp: it is the bottom of the band of the mesh's height strands grow from, 0 at the bottom of its bounds and 1 at the top.

strands and segments are what it costs: a strand is two triangles per segment.
