trying a project for rendering I came across with 3d head scans.
head shader 2 days.
Fabio for hair(around 4 hrs), eyebrows(3 hrs), and beard (2 hrs) well extra time was spend to implement a couple of new features into Fabio. (now each Fabio has its own mask at render, nice when are several fabios in the scene.)
