hi all,
just a note to let you know that we have have a new option on our prman export from Shave and a Haircut for Maya that does a space partition. it's a pretty significant thing, because there are no longer any memory constraints on hair counts. This feature also works with our 'instancing' feature set, where you can substitute complex geom such as trees and feathers for hair.
anyway, there's a 15 day demo on the site - worth checking it out.
