Delete points by $ID, Flip Fluids

[TheAdmira1]

Hello all,

I feel this is a trivial issue, but I cannot get it working properly so I figured this was the best place to ask.

I have some stray points in my flip sim that id like to remove before rendering. Im not sure of the best way to do this in order to ensure that the points are removed through out the entire range. Selecting the points and hitting delete obviously only gives me the point numbers for that particular frame as the fluid is changing.

My idea was to take the the group created on say frame 40, store the points based on their PT that frame, then transfer the ID of each particle in that group to another group, which can then be used to delete as their ID will not change. Only one problem, I cant figured out which approach is best. Should I code this? Should I do it in a vop? Is it even possible to make said transfer? Or is there a simple "Group by ID" that I am missing? I know I can group by ID, but I would prefer not to manually enter each ID for obvious reasons (laziness is the first to come to mind.)

Again, Im assuming this is a trivial matter, and quite a few people will think I am slow for asking. I just have never had to store particles based on one attribute and then transfer another attribute from that group to another group in order to delete, and would love input from someone who has.

TIA!
