Some weeks ago I found a page where someone ported a renderman barnacle shader
(I think it was this one http://accad.osu.edu/~pstuart/ADC/Hw4/hw.html [accad.osu.edu] ) to vex.
Unfortunatly I lost that link. Does anybody know where to get this shader?

Thanks again
Achim

I haven't tested it with the new houdini versions, so I don't know if it still works… Sorry for the late reply!

Peter.

thanks a lot
