particleIllusion After Effects Tutorial Part 1 (wondertouch.com)

particleIllusion After Effects Tutorial Part 1 (wondertouch.com): "While particleIllusion is not integrated with After Effects, the 2 programs can function well together, if you know what to do. There are several ways to both output and use pillusion footage in After Effects. This tutorial will cover several of the methods, as well as importing position data from After Effects. This tutorial assumes that you have a basic understanding of both pIllusion and After Effects, and that you can manuver around both programs' user interface. It would greatly help if you've done the first 2 basic particleIllusion tutorials, but it isn't necessary if you already know your way around pIllusion, and are just trying to figure out how to use it with After Effects.

I haven't used this myself. But it looked worth noting. For more information, see http://www.wondertouch.com
