I think i've found a way. But it involves using Photoshop to convert an original Kozaburo texture into one that only has details by using the high pass filter. I then built a shader tree to use this high-passed texture as input and produce lots of effects. This picture shows my results.

If you are very familiar with Koz's Long Hair Evolution, you should easily be able to see that the highlights have moved considerably. These renders were done with two lights, one front and high, the other from the left and low.

All the different colors were produced by changing only 3 parameters in an HSV node and occasionally a bias or gain value in my shader tree.

I'd give you the adjusted texture but that's not legal. But I can post how I did it and you can reproduce it yourself. Then you'll need my shader tree. Let me know if anybody wants more info.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
