Creating more of an existing Particle

So I'm making a particle field, specifically an asteroid field. I'm using the particle tool to sketch my particles directly into the perspective viewport, which is working out great. I sketch my particles and render them, but I decide that there aren't enough. So, I grab my particle tool again, but it just wants to create new particles instead of making more of my existing particles.

All I want to know is how to create more particles using the node I've already created. I've tried re-naming the tool to match the old one before I create them, but Maya just adds a "1" at the end or something. If I can't figure this out I'll probably just save my particles as a preset and re-draw them - it's much better than having to re-create them each time.

And I'm using classic particles or what have you rather than nParticles. Thanks!

Hey astu11,

the only thing that came to my mind was the emit mel command. You sketch your particles like you did before. To add the particles from your newly created particles to the old ones type the following:


string $myOldParticles = "nParticle1"; // insert your name old name here
string $myNewParticles = "nParticle2"; // insert your new name here

float $pPos[]= `getParticleAttr -at position -array true $myNewParticles `;
int $count = `getAttr ($myNewParticles + ".count")` * 3;
string $emitCmd = "emit -object " + $myOldParticles;

for ($i = 0; $i < $count; $i+=3){

$emitCmd += " -pos " + $pPos[$i] + " " + $pPos[$i+1] + " " + $pPos[$i+2];


eval $emitCmd;


This should do the trick.
