Dave: I'm using 4 hair systems on the front, and 2 on the back. There is a low layer of thicker hair, a top layer of finer hair, a finer hair system for the edges, and a fourth hair system for the side burns. Those front hair stop at the head piece and the hair systems for the back start there. Those back hair systems are thicker hairs than the front ones. Doing it this way I used fewer and shorter hairs.
I also only did half the head. There is no hair on the side you can't see hair. Doing it this way is the only way I could render with FG without my computer crashing.
I used one separate scalp for each hair system.
The eyebrows have two hair systems each.
Eye lashes are polys.
I am going to model a simple shirt as well.
Agai, thx for feedback
