Hey,

The setup:

1. A line with 20 points
2. I group those points but use the 'Keep by Random Chance' option to limit the amount of points in the group
3. I then expand that group over time
4. This is fed into a copy to points sop, with the target points option pointing to that point group. A sphere goes into the geo part of the node.

This results in a bunch of spheres appearing over time.

How would I go about including those spheres in a vellum sim given that the solver kicks in on frame 1 (which only features one of the 20 eventual spheres)?

Any tips would be appreciated!
