the New Year's party I was at...

Very fine and techie trick! I figure this hair would be very handy for
Blobman models with alopecia problems.

It looks great. It really took 64 patches? I will have to try this
technique out for myself and wish that I had thought of it.

tnx :)
> It really took 64 patches?
yes, but with some tweaking, I think I could do it with less patches... (or
less cloth-simulations, if I use them... or just meshes, or whatever)
Right now I'm rendering a simple model of an old man with white hair, but
it's taking way to long to be useful... 14h 11m 23s and only 23% of the
image is done :(

Actually I'm surprised that this technique is new to you all... I thought
many images done with professional rendertools used a similar technique.

Whoa! That's like a terribly bad hair restoration!
Just thought of where I've seen that hair before. Was at a zoo and it was
on the orangutan. Your photo doesn't resemble the ape at all.... except...
the orangutan had a high hairline too.
