floating particles

[mic3mic4]

Spent the better part of the day changing the shape of the big chamber and the tunnel. I'm using your events and it look so much better! I can't thank you enough. I had the problems you predicted and followed what you said. I did have problem again of the particles getting stuck - just like in real life, so I changed the friction to 0 and so far looks good. I'm not rendering just yet, still many things to do before I set things up. I believe more questions will come up soon enough..
How are you with pheonixFD?
