Hi guys,
there is much simpler solution I think, or maybe I do not understand what you want to achieve exactly...
1. scatter some random points
2. point wrangle with this conde
@pscale = distance(@P, point(0, "P", nearpoints(0, @P, 0.5)[1])) * 0.45;
3. sphere copy to points
all you need to do than is just delete all points but those you want
4. second line in the wrangle ( 10 points more every frame )
@ptnum * 0.1 > @Frame ? removepoint(0, @ptnum) : 0;
here the scene saved out with opscript
just copy paste it into Textport
