IDK… i think the 3D voronoi is quite interesting for this… so you just need some density control… and if you also use vertex painting for this then you don’t need any UV’s at all…
So according to the paper:
We would not be able to paint this complex detail, given our time
and multi-scale constraints.
So the also don’t have time for proper UV-unwrapping… but some vertex painting for example for the darker parts on the top and the back of the necks… respectivleythe the streaks on the backs…
For the density control maybe this could help:
