Keyframing particle emission rate work around.

Here’s a technique I’ve put together to keyframe the amount of particles emitted since those parameters aren’t keyframeable currently. Particle emitter is inside two animated offset collision objects. Particles set to “Die on Hit”
The size of open ‘holes’ in collision objects control how many particles escape.

looks good.

seems silly that you can’t set emission by now, it seems like such a very basic function. Perhaps a dev needs to be contacted.
