Right.
Trying to sort out what the different nodes are doing. Anisotropic I think I've kinda been playing enough with to know at least how Specular_Value and u and v highlight interact. Which is so cool... done some interesting things with shiny clothing using that and Edge_Blend.
And u_texture_coordinate is just a directional thing. Plugging it into the xScale is a bit weird to me, because the x-axis says side-to-side, not vertical. In the colourMap, the hair strands run vertically. Even the preview image is vertical. But hey, the stripes u_texture_coordinate creates don't do anything appropriate in the y scale or z scale channels - I tried - so x scale it is. I guess we must be talking about:
**Generally on any figure or prop, the U coordinate is chosen to go horizontally around the geometry and the V node goes vertically on the geometry.
**Meaning, the vertical lines are arranged horizontally across the geometry?
Think of it as latitude and longitude, like on a map. The value usually goes from 0 to 1 in both dimensions, but that is not an intrinsic limitation.
The same rules apply as to how to control the characteristics of the stripe. Play with this one for a while. Also try using the V node instead of the U node.
So I did.

Started to run into trouble. It was time to put up a test square, group and assign a material to the group, and try the texture against the group:

s = Surface()
s.Alternate_Diffuse = Blender(
  Spots(WHITE, IColor(0,8,190),.9,0, .25) * IColor(78,78,78),
  IColor(214,0,61),
  .8)
s.Alternate_Specular = Anisotropic(
  Specular_Colour = Fractal_Sum(.000004 * u_texture_coordinate(), 4, 4, 8, .3, .5 .5)
  Specular_Value = 4,
  u_Highlight_Size = .2,
  v_Highlight_Size = .6,
  x-dir_x = 0,
  x-dir_y = 0,
  x-dir_z = 0)

Gets me this:

No idea what is causing that disruption in the texture 3/4 of the way down. Any ideas?
