Translation of Procedural Hair

[Groovedog]

On another note, when I go to a new material and try to create a gradient ramp in the opacity channel.
Now add some noise to it.

When I change to VW mapping the noise goes away. Bugger :\

I got it to work here by doing this:

create a plane & put a UVW map on it, change setting to 'UVW to XYZ)

create a gradient ramp material, from black to white to black, tiling 15 times. Make the mapping coordinates 'planar from object XYZ'

Assign a material to the object, in the opacity map place a gradient. Again make the mapping co-ords 'planar from object XYZ'. Set the top & bottom colours to black & drag the previously created gradient ramp material onto the middle map button of the gradient map - choose instance.

That should give you a material of hair strands, the amount defined by the tiling of the instanced gradient ramp material, & the opacity top & bottom defined by the gradient material.

I tried this with a gradient ramp nested inside another gradient ramp, but the result seemed intermittantly buggy :shrug:

You can create the effect using 2 gradient ramps and using a mix material to combine them.

For the hair strands (Map #6) I created a gradient ramp, applied some noise, tiled it, and rotated the map 90 along the W.

For the ends of the hair (map #8) I created another gradient ramp that was placed in the mix channel of the mix map.

Here is the sample scene I created in MAX R4 format. Use it as you like for a training tool, if you make some changes that would be useful to others please post it back to the forum.
