Deleting FLIP particles with POP?


Recommended Posts

Hi Everyone,

I am new to Houdini, I started learning it a couple of weeks ago, and I love it of course!

I bumped into a problem recently and I can't seem to get my head around it unfortunately.

I am trying to delete particles from the FLIP solver on a frame so on the frame after the delete, the sim continues like the deleted particles wouldn't have even been there.

I am isolating the particles to delete by grouping them with a bounding geometry on a certain frame.

I have read that by connecting the pop solver to the flip solver's second imput can do something with deleting particles from it, but I couldn't figure it out how to do it.

I would really appreciate any help and advice. :)

Hi Pazuzu and Dobin,

Thank You for your prompt response! :)

Pazuzu, the scene You made is perfect, it is doing exactly what I was trying to achieve. Thank You so much for your help!

And this has taught me a lot about the sop solver, so thanks for that as well! :)
