Question

How do I pre-prime a particle system so that it looks like it has been running for a while already?

Like this:

var simulate = 1.0;

function Start()
{
    var step = 0.03;
    for (var i=0.0; i<simulate; i+=step)
       particleEmitter.Simulate(step);
}

(I tried to use ParticleEmitter.Simulate a while ago without success, but today it suddenly dawned on me how it needs to be used - basically you need to call it with small time increments, just as it would get from a slow progress of frames; I would argue that the simulator should always have a minimum resolution - like that 0.03 above, and should sub-simulate even when the framerate is low to ensure a reasonably consistent visual result)
