thank you for the tutorial.

well, now i have other problem. before i used dynamics. but now i'm trying to do same with nDynamics. and it doesn't work. when i create emitter and click on play button, timeline slider steps to frame 2 and nothing happens. after 10 secs or so it jumps to frame 200+ and so on till the end of the timeline. no particles are emitted. that happens only when i'm creating nDynamics emitter in my large scene. in the new empty scene everything is working good.
