How to turn off an emitter
on Aug 21, 2005 at 11:24:50 pm

Hi Folks,
Really new to this and struggling through the tutorials but I cannot find the answer to one thing. When creating a sequence I want to change from one emitter to another (stop one and start a new one) but cannot find out how to do so. I may be having a mind block here and missing something really basic but would really apreciate forum members help.
Many thanks
Mulhuis

You can set keyframes on an emitter's Active graph to turn it on and off.

Select the emitter in the Hierarchy window (the left side of the screen), find the Active graph (it has a green box beside it), and then click in the Graph window at the point where you want the emitter to be turned off.

If you'd rather fade the emitter out instead of having it dissapear entirely, set some keyframes in the Visibility graph instead.

In some cases you'd rather step the "Number" property down to 0 instead of using "active". Also, turning down the visibility of particles to 0 isn't the most efficient way to get rid of them, because they're still there taking up computation time even though you can't see them.

If you did want to turn the visibility down to zero you could then turn the emitter off too, wouldn't that save on the computation power?
