Very soon pIllusionRender will be included with particleIllusion 3.0 -- it will no longer be available separately. If you own 3.0, you'll be able to download pIRender 3.0 for free when released, but here's an updated beta version that will work for 21 days:

Please give this a try ASAP, especially if you've used pIllusionRender before, or have a need to use it! I want to release this within a week, and need some testing on it.
The docs aren't too detailed, but you shouldn't need to know too much to use it. Please check it out (if you think it will be useful) and let me know if there are any problems.
If you have no idea what pIllusionRender is, it's the standalone renderer for pIllusion project files. More info here:
