Right, I am using a couple of PP expressions, a creation to get them to be born at random rorientations and a runtime to get them to spin randomly. I'll ge those up soon. I just don't have them with me right now and I can't remember the exactly off the top of my head.

As for the intersection, I found that for what I'm doing at least, having a non-renderable collision object slightly above the rendered ground plane works well.

Thanks in advance, guys.
