Nurbs Hair

Hello,

Little post to talk about the nurbshairs.

How it's work ?

Simply, you just need to create nurbs cylinders or plan and create a nurbshair procedural, choose the nurbs cylinder in the procedural of the nurbshair and attribute a shader of hair to the nurbshair.

To tweak easyly the hairs, it's better to add a single light, like a spot light.
I have some bugs with distant spot for the specular.
Do not activate the shadow before finishing your tests because the render time is much longer.


At this time, everything works fine !

But, There always have a but, I need more parameters !

I can manage the hairs inside the nurbs surface, but I can not extand the hairs outside the surface like the multi strand in shave.
So I have some lines in the hairs as you can see in my picture.
Finaly that dosn't work very well and this is very hard to have a good continuity of the hair.

I need more parameters for the perturbation, for clumping, tip clumping, tip peturbation etc
The actual values are in 0.00#, so it's really difficult to tweak as we want.
