I started a thread with my hair tests, so I thought it would be worthwhile to link to it here.
The images are on my friend’s server, and it’s not up at the time of this writing, so check back later.
About lukep’s hair. It looks pretty nice. The parts that would annoy me if it were mine, are the parted areas, and the little frizzy hairs. The parting is something I tried to solve in my tests, but I wasn’t satified with the results.
The skin procedural looks pretty nice, but maybe lighten it up a bit on the circles, it looks kinda fishy.
Very good work overall, congrats.
