It a bit far for me so I will check it when I come back home ;)

I forgot to show the inside of the group 117 (just above the delete). That's in this group that you will chose the primitive that you want for the current iteration. You have to write the following string in the "Base Group" text box : " @name=piece`floor(fit01(rand(detail("../foreach_begin22_metadata1", iteration,0)+1231),1,50))` ". This will create a groupe with the only piece that is called "piece45" for exemple. In my case I set the possible names from "piece1" to "piece50" but that depend on the number of primitive you have left after destroying the outer ones. In my case i have "../foreach_begin22_metadata1". This have to point to your personal metadata in the last foreach loop. So be sure to have the right name. I used the same principle in the transform145 at 0:22 to randomize rotation and scale. Hope it helped solve your problem, have a nice day !
