That's beautiful - perfect. Thank you!

Sorry, should be good now.

Thank you!

In the image above, the chance was set to 100%. I had tried it at different values and still works the same (except 0% which results in no Reproducing which makes sense).

I'm not sure why some are not adhering to condition. My scene is 600 frames long and the longer the scene plays out - the less Reproducing happens.

I made a scene of firework using:

• a Basic Emitter to emit the initial shot
• a Condition based on Age of the particles shot with Inside Range (Lower: 50F, Upper: 90F)
• a Reproduce Emitter parented to the Condition so when a particle hits that condition it spawns.

All was working fine until I noticed there were many particles that were not triggering the condition. Why would that be happening?

I made another condition to increase the radius after 90F Lifetime to see how many weren't adhering to the condition:

It seems like when I reduce the Reproduce Emitter from 60 down to 10, all works fine - they all explode.
The settings I had on the Reproduce Emitter:
Count: 60 (or higher)
Per Particle
Count Variance: 5
Kill Source: on
Continuous: off

SOLVED: See below

Wow, these options are amazing. I greatly appreciate your assistance. I am currently teaching a Simulations course and the new particle system, which is amazing, has me trying to reconfigure how I was doing things before.

You always deliver! I love the solutions for parv_01 and 02. Really opens up more possibilities. Thank you.

Thank you, I will take a look at the scene.

Hi, One thing that I would do using Thinking Particles and Xpresso is to give a particle a particle random value. For instance, assign each particle a random height between 800 and 2000 and when the particle reaches that random height, it would spawn new particles.

I have not figured out how to do that with the new particle system. I was able to use a Condition to determine whether the particle is Greater Than the height of 800 and then adjust the Chance to add randomness to that. But it is difficult to specifically dial in a range of values. I will still getting a few going higher than 2000 (I wound up just exploding those when they were past 2000).

Thanks, Dan

Is it possible to use the Stick Modifier to stick a particle group to another particle group?

For instance: If Group A is emitting large ball like particles, can it bounce on a platform that has tiny particles from Group B on it, and have the Group B particles stick to the Group A particles? The Particles from group A is using a geometry replacement with a Sphere through a Cloner object.

I tried placing the Stick to the B Group particle group. I made the Sphere a polygonal object and the added the Collider tag to the Cloner object. Strange thing is, the Group B particles will stick to the first Group A particle with the Sphere replacement, but not other Group A particles.

Fantastic, thank you.
