well,
whatever works… some put particles on an extra layer and then move the layer.
but there’s also a checkbox which binds the emitted particles to the movement of the emitter, that’s if you move the particle emitter all the emitted particle will do the same move. so, you wouldn’t need an extra layer just for that purpose.
i’m not in front of c* so, i cannot tell you the specific location, nor the exact name of that checkbox, but it’s there 😉
