In a flip sim I am using a wrangle to tag flip points that match a certain condition. My goal is to remove the tagged points from the flip object when they meet that condition, but keep them around so they may be extracted from the dopnet into SOPs on every frame.

What is a good way to remove the points from the flip object as soon as they meet their condition but also keep them around so all of the "removed" points on any frame are available in SOPs?

maybe use a SOP solver in DOPs and store the points you don’t want in the FLIP in some sort of inactive group, then in SOPS you can separate active FLIP points from inactive FLIP points.

Also maybe look into particle streams since your also working with particles in FLIP
