How can I have a particle system emit few particles at first, then more particles, then less particles again?
I am using a particle system for rain that rains a little at first (rain drizzle), then slowly increases to a lot later (rain showers), then slowly stops.
|rain/particle emission distribution
|amount of particles emitted
The linked question "Is it possible to change the emission rate of particles over time?"'s answers are all nearly 10 years old, and does not create acceptable emission rate.
Particle system emissions are in terms of emission over frame range (not emission rate), and is not an animatable property.
