From what I've heard the particle emitter is one of the things on the agenda for version 5, though there hasn't been any official announcement of anything. I've used Potentializer, and I find it great for bending and warping effects, and for "imprinting" snow after footsteps. Check out this thread at 3dxtract: http://www.3dxtract.com/cfforum/viewmessages.cfm?Forum=17&Topic=525 Show the hehe potential of potentializer!:) The plugins will be updated for CS4 for free, not sure when though, but akuro did say that they would be. I don't think the CS4 SDK has been officially released, so could be a week or two. Brian
