GeorgeZ Posted July 31, 2013 Share Posted July 31, 2013 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. Thanks, George Quote Link to comment Share on other sites More sharing options...

dobin Posted July 31, 2013 Share Posted July 31, 2013 try "Sink from Object" tool from the shelf on your bounding geometry Quote Link to comment Share on other sites More sharing options...
GeorgeZ Posted July 31, 2013 Author Share Posted July 31, 2013 (edited) 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! Edited July 31, 2013 by GeorgeZ Quote Link to comment Share on other sites More sharing options...
vinyvince Posted February 25, 2018 Share Posted February 25, 2018 Hi guys Im actually looking myself for a way not to delete, which i manage to do already but with a distance falloff value for smoother transition.. Any suggestion ? Cheers, Quote Link to comment Share on other sites More sharing options...
