2nd Vellum animation on a Simulated Object (stopped point)

[Matt.b]

Hello everyone,
I'm new to Houdini and the website,
but I need your help because I'm trying to create a Vellum simulation on top of another simulation.

Long story short, my first simulation looks like this:

(Sorry, I don't know how to use an image with a URL)

Then I run it in a for each loop so I can refract each piece while maintaining the animation.

With an exploded view, I have this:

And now, where I'm having trouble:

I want to rerun a Vellum simulation that will make each fragment fly with the popwind. To do this, I've already defined propagation attributes. I simply want the parts to follow the first simulation until the "activate" attribute is equal to 1. Then, each part with attribute 1 becomes independent of the simulated mesh.

I don't know if this is clear, sorry, I've been on this for 4 days with ChatGPT and a tutorial, but I can't figure it out.

I've tried many parameters and a lot of VEX code like this.

This is the simplest test I've done. There are others in the .hip, but I got the closest results. I don't know why these points disappear. But with another configuration, I got simulations like this.

they take too long to cache so i can't show you the 100+ frame,

But yesterday with a setup I managed to make each piece fall according to the activate attribute, but the pieces that did not have activate at 1 therefore stopped at 0, did not follow the movement of my basic simulation,
I hope that someone will have the faith and the time to help me, thank you
