[Sidefx-houdini-list] Killing cached sim particles

Hey Andy
 
Its that old procedural problem with not being able to maintain a history of the data. Sounds like a job for the sop solver again which should do that for you. Theres some examples of dynamics transferring colour geometry that maintains its history i.e like attrbute transfer over time.
 
The pop solver method should work tho :¬/ I dont know how you set up your pop solver but im guessing you need to create a group based on the volume that they enter then kill it? I cant say for sure without testing though. Of course you could do it to the actual popnet before you cache it but that defeats the purpose :¬D
 
I think the sop solver may be your best bet.
Cheers
Nick
