hair gradient material and 3delight
hello all. I've just focused on 3delight in softimage. rendering hairs with 3delight in softimage is much faster but it seems there is no support for hair gradient material and it's the result when you assign the material:
// ERROR : 3Delight: S2050: cannot find shader 'DefaultLib_Hair_Material_surface', will use 'defaultsurface' and the hair goes gray
i think hair gradient material is very powerful because of its gradient features specially it's cross transparency support. please give me some guides for using this material with 3delighe. thank you so much

Re: hair gradient material and 3delight
hello,
if it's all about cross-transparency, you can get it with standard gradient texture node, plugged into 'transparency tip' or 'root', of standard hair shader. 'Horizontal" gradient is cross - transparency. If this doesn't work for any reason, there are 'scalar state' nodes, barycentric lengthwise or crosswise, you can use them as input of gradient mixer, or something else.

Re: hair gradient material and 3delight
thank you amm for replying. i tested it, gradient and scalar state nodes works fine but i cant set cross and length transparency simultaneously, it's limited to one. do you have any trick for this? thank you for your kind advises :)

Well I've just tried to plug a 'vertical' gradient into color input of 'horizontal" one, and this worked in 3dl. Even it's really not only way. If you are new to Softimage, just don't forget that numbers (color1, color 2 and so in gradient texture ppg) are relative to time of input. That is, if you have two colors and create another one, this is 'color3'. Also, if you use tabbed style ppg, there is a good chance for editing the wrong gradient. Maybe it's good idea to try everything on plane with planar texture projection, first.
