Possible to go from 0-2000 particles (Particular) in under 1 sec?

Hi,

I'm currently learning particular and one thing is really puzzling me. How do I control the exact number of particles I want to be on screen at any specific time?

I'm trying to get particles to go from 0 to 2000 in under one second, but it is taking them 5 seconds for all to appear, no matter how close I put the two keyframes or what settings I change. I can't get anywhere close. At keyframe for 2000, there are but a handful of particles, and after that it seems to be fully up to particular as to when it will show them all.

TIA.

If you have for example 30fps and you want 2000 particles to appear during the first frame: 1 frame = 1/30 sec

you want to generate 2000 particles in 1/30th of a second:
particles/sec = 2000 / (1/30) = 2000*30 = 60000

So on the first frame set Particles/sec to 60000 with a hold keyframe, and on the second frame set 0, also hold.

You also need to check that Size over Life and Opacity over Life curves start at their max (no ramp up).
