a hair map i did in blender, worked best when I tried weight painting for density.
Sculpt in blender 2.8
A messy wireframe i did while trying some quick retopo options, it worked, but i wish i had spent more time on that part.
It started out as an exercise in sculpting, but i decided to take it further and try out different ways of generating hair, textures, rendering in eevee etc. Lots of fun, learnt a lot! All in blender and substance :)
