Multiple Particle streams from 1 dead particle (Particle Fireworks)

Hi,

I am making a fireworks particle setup and have run into a problem. When the initial particle (the firework arrow) dies I want multiple bursts of new particles to emerge to get more variation in the particles. However in the way I am creating my streams I only get the first burst. (screenshot attached)

Any help would be much appreciated.

Cheers,
Aaron

make sure BURST_PARTICLES has Kill Original Particle OFF
also use second input of POP Replicate, not first, to avoid your source being executed 3 times per timestep instead of 1

Hi Thomas,

Thanks! I got it working now but for the first POP Replicate I do need to use the first input, otherwise I get no bursts at all, so that has me a bit confused. Could you explain how this works or the logic behind it?

Trying to add a third particle stream to make smoke out of those and having the same issue. The two burst streams still works no sign of the third one when I let the simulation run. This is getting quite frustrating since I don't understand why this is happening.

Again, any help is welcome!

the smoke particles are emitted, but unfortunately since POP Color node has default for Alpha 0 instead of 1 all new particles that don't have Alpha set will have Alpha 0 so invisible

just tick Update Alpha on popcolor6

That still doesn't seem to work unfortunately. The weird thing is that the particles do show in the render view but are nowhere to be seen in the viewport.
