hello every one.
I want to detect which particle just collide in FLIP sim.
in POP, I just need to create a hitID by collision pop and a attribut node to reset this hitID value to 0.
so that when particle hit it will bake a 1 value and in next frame will return to 0.

but how to create a hitID for FLIP? I already check FLIP solver parameter but there seen has not something like hitID.

could someone give me a help, please. other method is welcome, of course.

thank you!

Hi all,
same here.. Is there something equivalent to the impactAnalysis relative to FLIP fluids ? I need to group the “just hit” FLIPS particles.

Thanks!
