  • How to use a bezier line as emitter source?

    Posted by Dietmar Jokisch on July 11, 2014 at 10:17 pm

    I would like to create a curvy line, which emits particles. If possible, it should be a closed line (like a wavy rectangle), where the particles move from the outline to the center. Or for another idea: an animated wave (line), where the particles come from and move just upwards.

    After some tries, I gave up and now need some input how to solve this….

    Simply select “Geometry” as the emitter source.

    Thanks! I already tried this, but the behavior irritates me a little bit, aas I come from 3d, my experience is, that an emitter emits particles from a given object or points, no matter where the position of the emitter is. Now in Motion 5 this is not the case and if I want the particles to be “created” from a moving line, I have to group the line and the emitter.

    Here’s a short example movie, where I have set the emitter and the line to Y = 0. But when I move the line down as shown, the particles do not emit from the line anymore but stay at the position of the emitter. For me this is no real “emitting from geometrie”, but I may have missed some behavior tunings….?
