Default Emit upon death

Hello all, I'm wondering how to make particles emit other particles when they die? Just can't figure it out, would be very appreciated for any help..

Thanks!

If you can, try to check out the rain tutorial. I think it has something in it that emits particles when the rain hits the ground. But that might just be a particle collision event. Oh well, someone really smart and knows alot will help more than me.

I'm still learning dynamics, but I don't think it can be done. I think alienscience is correct that it would have to be a collision event.

From Maya's help:
You can also make particles split, emit new particles, die, or run a MEL script when they collide with geometry.

Either that or maybe it could be with MEL... but I haven't even dipped my toe in that yet.

if(particleShape1.age >= particleShape1.finalLifespanPP)
{
print("dead particle\n");
//do something here
}

Enter that as a runtime expression on the particleShape and that should do it. You can then use that even as a time to spawn more particles or get the world position of the dead one and spawn from there or whatever.

Thanks, pardon my very limited knowledge of particles here but what's the command to emit (where the particle die in my case)?

Can't find anything about that anywhere..
