I'm with HellBorn, Richardnovak77. Particle Illusion rocks big time. Awesome effects, realtime rendering, no "trial, render, readjust, rerender", etc. I just got my copy a couple of weeks ago and don't regret it one bit. This solves ever needing to wait for a particle system for any software that you enjoy using. Even my beloved Lightwave can't render them as quickly as PI, and it's a heck of alot easier. Check it out.
