help on assign root and tip color of fur when using miExportMaterial on fur

[hshhst]

i am following this tutorial to use override material on maya fur,

http://blog.the3dagency.com/2010/02/...-maya/#more-71

it works smoothly, but i find some difficulties in assign the root and tip color of the fur,
i know that there is a ctrl_scalar shader to make use of scalar state's Barycentric A / Crosswise Hair and
Barycentric B / Lengthwise Hair to color the fur (like XSI)

could some body give me an advice on how to get the scalar state shader to work in maya,
or the source code of ctrl_scalar


i work on Maya 2011 x64, windows7 64bit

I suppose ctrl_scalar works similar to my p_hair_mapping.
In theory, for length mapping you just need connect state->bary[1] (that these shaders return) to your ramp1.vCoord
Also you may use any mix or blend node.

Thanks a lot!
