Hi everyone,
Let's say I have some particles following a motion path. Towards the end of the sim some particles start to be too fast. Since for the scene I'm working on the number of particles has to be constant from first to last frame, how can I delete them from the beginning? It's a big sim so I can't delete the manually.
Thanks!
Remove particles since first frame

you can specify adhoc group by any attribute, like id, so if you have stable id's on your particles it will delete only partiles with specified ids

That's almost what I need. The only problem is that I can't do it manually because I have around 60K particles and they are all mixed. Is there a way to do it with VEX setting a treshold for velocity and delete them based on their ID?
