Making particles fly by?
This should be pretty simple, but I’m not sure. What I’d like to do is basically make it look like particles are rushing past the camera (although I don’t think I actually need to make a camera for this), kind of like driving through snow or flying through space – I might use words or symbols though. Anyway, how would I achieve this best?
Right now I’m using Particular with a point emitter/direction: outwards/250 velocity/opacity 0-100 over life span so it looks like they’re coming from a distance. However, I’ve seen videos where it looks much better – instead of going outward like this, particles look to really be moving through Z-Space. Do I need a box emitter instead? Any help would be great. It seems like this is a pretty easy thing, I just can’t seem to see where I need to look. Thanks!

Well, using a box with an Emitter Size z – 500, x – 100, y – 100 seems to help a lot. Looks like I want it to mostly, but I’m still wondering if there is a better or more realistic way I’m overlooking.

Add a camera into your comp and keyframe the z position at the beginning, move ahead in the timeline, and move your camera forward on the z axis until you see its position having the particles move past.
For example, at the beginning your z position is at -1867 (I think) if you use the 35mm preset on the camera. Keyframe that position at the beginning of the comp, move forward a couple seconds in the timeline and change the z position to 0. You’ll see you moved forward. Adjust as needed. Good luck!

Drop by the Cycore site and download their particle world demonstration files. You will find exactly what you are asking about, flying through a stream of particles. it’s cool. No, you don’t need a camera but you will manipulate the camera that is in the Particle World system.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”
