Hello Benjamin.

Apparently I was under the wrong assumption how prev_Frame inside the solver sop works. Your solution worked perfectly. Thank you for your help!

In order to get more and more familiar with Houdini I sometimes just start trying to create an effect that comes to mind and this one has me stumped even though I thought in theory it should be pretty simple.

The premise is that I have a few particles from a popnet simulation. Afterwards I change their color to red over time and offset the color change animation randomly per point. Once the point is fully red I split them off to a different group. Now comes the part I have trouble with. Once they are added to the different group I'd like them to hold the position they have been at and not move any further.

Normally this would be easy with a timeshift node but since the group transition happens in random increments I don't have a specific frame to work with.

Is there any way in vex to tell each point when it enters the new group not to change their current @P value and basically freeze in place?

Any help would be appreciated

Thanks a bunch. I kinda see my mistake now regarding the packed geo. But it seems now the copied objects are not really lining up with the points. They follow the animation but seem to have an offset in their position.
