Wow. While I agree that blondes are the hardest to get right, that DOES look very promising !

I surely do hope you can replicate that shader in Poser. :-o

Good job. Very good job.

 

BTW, Poser 9/PP 2012 actually have a new hair shader node. It wasn't 100% ready yet, so it's still hidden, but it can be unhidden via a python script.

Let's hope SM finishes it with Poser 10.
