Is it possible to change the emission rate of particles over time?
E.g. Start off with an initial burst of particles, then emit at a steady rate.
Here is a (poor) example of what I mean by the emission rate:
Is this possible to do using only one particle system? (This is necessary because the particles are being used to emit smoke)
The gif above was made by manually sliding the End value, but it gives strange and unpredictable results (as can be seen in the gif) as well as not being keyframeable.
