Hey guys, I've just posted my first tutorial. Its a Max / Vray grass tutorial, although the tecnique can be used with MR. I've been asked alot how i do my grass, so i thought i'd explain it. I expand some on the technique briefly mentioned by Peter Guthrie and James Shaw of using GroundWiz to paint the grass as vray proxies onto the ground. Hope you find it useful.
