Persistent Point ID on Changing Topology

[ParticleSkull]

Hello guys, I found a lot of topics on this and no one seems to solve the issue but i think it might not be impossible

I have this ripping cloth with and extrude node at the end, so it's changing it's point count and consequentelly every point number is also changing.

Is there a way to add a unique and persistent ID to every point, creating new IDs for the new ones?

Try this in a wrangle:

@id = @ptnum;

Hey Sean, thx but that's the problem. The point numbers changes over time, I need an attribute that "sticks" to the points

EDIT: here's a close look on point numbers at the corner. I need an id attribute that doesn't change

You should add IDs before the topology changes or at the same time the point gets created during a sim. Assigning IDs after the fact is close to impossible. 

Should be straightforward enough with a cloth sim though. Take a look at how POPs does IDs and replicate that.

Thank you very much, Skybar. It's not the 1st time I learn something cool from you

Add the IDs before worked just perfect.

Cheers,
Alvaro
