I wish to create a fractured RBD sim that has objects added to it over time, I tried setting this up but it only added the objects from frame 1. Any help would be great!

its hard to guess from that short question on a wide field, but if creation time is set to 1 it just creates objects on frame 1
If You want a steady stream use $F and link to a sop that provides the geometry needed on that frame. once the geo is released into the sim it keeps there, and must be deleted by sim

That just creates an insane amount of objects.

it just creates as many objects as you want, still not enough info
