The clumping seems pretty well simulated just with by using the color map. I mean, maybe it could be done a little better, but I am happy with these results.
I still have some bug preventing me from using vertex painting to change the length – I took a look at the master material and saw that indeed the alpha channel was going to the right place… it is something I will look at a little further in the future, but for now this model is at a good finishing point and I’ve got to move on. But man! I can’t wait to make some more furry critters and put this shader to good use.
Thanks again for the excellent asset and prompt support!
