Emit Particles from Particles

#1

Hey all,

I’m trying to emit particles from particles after a certain frame and based on velocity.

Essentially I’m trying this:

$vel = mag(particleShape1.velocity);

if (frame< 40) and ($vel >0.25)
{
particleShape1.emitter1RatePP =10

}
else
{
particleShape1.emitter1RatePP =100;
}

I can easily emit particles from another particles velocity, but how do the procedure above? I’m sure it’s extremely simple, and forgive me - I’m quite new to expressions.

Best,
Colby

if ((frame <100) && ($vel >1))
{
particleShape1.vertexEmitter3RatePP = 10;

}
else if ((frame >45) && ($vel >.25))
{
particleShape1.vertexEmitter3RatePP =50;

}

I guess this worked! I was getting an error before, but I must’ve just typed it wrong.
