select the partical emitter object and the enter the editing room (or just double click the emitter)...you need to set it to emit "objects" and they also must be emitted in the correct direction and at a slow enough speed to be visible. fwiw, I have found several things that you can not do with the particle engine (eg: you cant nest partical emiters..such as emit particle generators from a particle generator which is kinda sad because you could do so much more with it if you didnt have to duplicate an animation/generator that you can create so easily with a single generator...)...but in general, its a kick arse kinda tool. :) BT
