Hair - how to define parameters with texture?

[srvargas]

Hi everyone.
I have this problem - the hair property page has the option to control various displacement parameters (kink, frizz) with a weight map/texture. I want to use textures but when I try to use the Transfer Map function I simply cannot select any of the textures that I have - either as clips or as textures applied on other objects...What is the correct way of doing this?

i havent done this myself, (still waiting for xsi2.....)
but i imagine it will need to be projected onto the object you are hairafying.......
otherwise a 2d texture is kind of meaningless for a 3d process.

I sort of found a solution - put a texture with a projection to the object (of course without assigning it to a material connection - just parent it to the object) and that puts the texture beneath the hair node in the explorer stack. Now it is possible to select the textures as maps defining hair parameters...
Anyway I didn't have time to see whether the render is affected at all >> If anyone has tried stuff with hair share some thoughts.
Thank You

yes, it works fine. Especially weightmaps. Great for locking frizz or kink or certain areas.

Mike - can you elaborate what works fine?
How exactly do you apply textur maps to control parameters?

paint a map on your poly object. 0 on the map will give you zero effect for what you map it to. 100 on the map will give you the amount you have dialed up on the slider.

use the transfer map button to select your map and them connect it up to the attribute you want.
