Hi

I’m trying to emit particles from particles, that’s easy right, but I only wanna emit from certain particles that are colored red as an example, so if I have my first particle stream going from white to red I only wanna emit from the red particles, I think that’s clear :D

thank for the help

You could use an expression like this

$rgb = particleShape1.rgbPP;

$hsv = `rgb_to_hsv($rgb)`;

if (($hsv.x) < 0.1 || ($hsv.x) > 0.9) {
 print "particle is red\n";
 // do something
}
else {
 print "particle is some other color\n";
}

Thanks Michiel
that works great
This is what I did if anyone else needs this
added per-point emision rates then

$rgb = nParticleShape1.rgbPP;

$hsv = `rgb_to_hsv($rgb)`;

if (($hsv.x) < 0.5) {
 //print "particle is red\n";
 //do something
 nParticleShape1.emitter2RatePP = 50;
}
else {
 //print "particle is some other color\n";
 nParticleShape1.emitter2RatePP = 0;
}
