I don't have the time to test right now.

Is it possible to create a view entity (model in front of everything) and attach a particle emitter to it to create a sort of energy flow effect?

I just wasted a whole day making a stupid animation in Photoshop that still looks exactly like what it is...a picture. And I need 3 more with different heights.

Particles are what I'm looking for, but haven't tried to put them on screen.
