Hey, I am simulating a Flip sim on a SOP level with a new solver. I am looking for a solution how to delete older particles with @age attribute but I can not find any settings in the corresponding nodes. Maybe I am missing something but on the other hand this may be done inside the flip solver. Is there any quick solution for this on the SOP level? If not I would appreciate pointing a finger in a right direction in case this has to be done inside the solver with wrangles and vex. Thank you in advance.
