I've been playing with a new method, one that doesn't require any anti-whatever on the way in.

I used something like this in my AMUCFS shader, but I didn't really understand the math very well at the time, I did it in a more complicated way, and I didn't really explore how imporant it is.

You can try experimenting with this.

Build a shader adding together all the elements of diffuse, specular, reflection, and so on as you'd do for a GC shader, but skip all the incoming anti-GC stuff.

At the end, given your assemblied linear color, c, you use:

s.Alternate_Diffuse = c * (HSV(c, 1, 0, 1) ** -.4)

Wacky, huh?
