Hello.

I have 4 emitters linked together into one nParticle system. Each emitter emits a different sized and coloured nParticle. nParticles are goaled to four different curves (attached to the CV's of the curve). Now what I need is for each emitter to emit a specific number of nParticles for each curve (curve 1 - 20, curve 2 - 43, etc...). I can get nParticles to every CV point if I set the Max Count value to a high number but it is more than I need and I get an unwanted pulsing effect as nParticles emit on top of each other. Below is what I have so far in terms of expressions. Thank you.

//creation

if (nParticleShape1.emitterId == 0)

{

nParticleShape1.radiusPP = 1.7;

nParticleShape1.rgbPP = <<0,0,0>>;

nParticleShape1.goalWeight0PP = 1;

nParticleShape1.goalWeight1PP = 0;

nParticleShape1.goalWeight2PP = 0;

nParticleShape1.goalWeight3PP = 0;

}

if (nParticleShape1.emitterId == 1)

{

nParticleShape1.radiusPP = 1.2;

nParticleShape1.rgbPP = <<1,1,1>>;

nParticleShape1.goalWeight0PP = 0;

nParticleShape1.goalWeight1PP = 1;

nParticleShape1.goalWeight2PP = 0;

nParticleShape1.goalWeight3PP = 0;

}

if (nParticleShape1.emitterId == 2)

{

nParticleShape1.radiusPP = 1.52;

nParticleShape1.rgbPP = <<1,0,0>>;

nParticleShape1.goalWeight0PP = 0;

nParticleShape1.goalWeight1PP = 0;

nParticleShape1.goalWeight2PP = 1;

nParticleShape1.goalWeight3PP = 0;

}

if (nParticleShape1.emitterId == 3)

{

nParticleShape1.radiusPP = 1.55;

nParticleShape1.rgbPP = <<0,0,1>>;

nParticleShape1.goalWeight0PP = 0;

nParticleShape1.goalWeight1PP = 0;

nParticleShape1.goalWeight2PP = 0;

nParticleShape1.goalWeight3PP = 1;

}
