Thanks for the encouragement, everybody!

arrow1, theoretically, it should work for anything you would normally use a particle system for. Water is best accomplished with fluid simulations, which are different, but you can fake certain things with particles like fountains and waterfalls. I've heard that fluid simulations work better for smoke too, but I think it is very common to use particle systems for smoke. You can apply any material to the particle that you choose to make it look as you wish. In the future, I may choose to allow different geometries for particles too, but for now its just a camera facing triangle that you can apply material to. Note that this includes transparency, so it does not need to look like a triangle, of course.

Here is an old example that I made a couple of years back using my system to produce a rocket engine effect: Rocket Demo for Particle System for Poser
