Hello there! I have been wondering what could be the cleanest way to have only some specific points on a mesh (say, grouped by attr or something else) to be fed into a particle system, removing the points the particles generated from (basically switching from a point to a moving particle). Of course I know all the standard sourcing pops practices, but my problem lies in the fact that I want to do this in a gradual way over time. For example, frame 1 = all my mesh points are still points, frame 10 = a group is created of 10 points, those 10 pts get deleted and fed into a popsystem, frame 20 = my mesh still is going forward with all its points except the 10 I used to spawn particles, and another group gets created, those points need to be deleted and fed into the same particle system and so on and so forth. In the past I approached this in different ways (manually creating hdd saved geometry for the spawn frames and use those as source, get all my mesh to be a particle system and only affect some based on pop grouping etc) but I haven't still found a more elegant and streamlined way to do it. I have thought about doing a growing group in sopsolver, but the particles that are there would stay in that group, meaning that if that group is my spawner, it will always emit all the points in that group at every frame. Also thought about stepping forward in time by 1 frame, regroup and subtract from the previous group (so I would get only the "newest" particles each frame), but this would mean cache my points to disk before doign this operation which might be too convoluted. Any thoughts/best practices/ suggestions about this? Thanks!
