vray fur - how to make it stripey?
show user profile  mike_renouf
I'm rendering a paint brush, and I've tried a couple of methods for making the bristles. What I'm aiming for is black bristles with light grey tips (just the 3 or 4mm nearest the tip).

This image shows the sort of change of colour to the tips that I'm after:

Firstly I've used Max's hair and fur, with mrprim mode and the standard hair shader settings. This seemed a bit slow and I couldn't immediately see how to alter the colour of the bristle tips, so I switched to using vray fur. This was a little quicker, but I'm still at a bit of a loss as to how to make the colour change.

Any ideas please?

I'm not familiar with vray fur but I know zbrush's fibermesh. It's easy to set up, can just use morph targets to define where you want the bristles, but there's one major advantage: uv mapping for each bristle. It maps each hair to a square uv map. If you don't have zbrush and need me to set it up for you I can do it tonight after work.

You could use a gradient ramp.

Thanks chaps! (And sorry for the delay in replying). I'll post a WIP when I get a moment :)
