@6ixpool: No worries, man! You already set a lot of ideas off, and figuring stuff out is fun. 
I have to turn you down on the collaboration for now though - I really want to make and figure out this thing myself, ain’t nothing personal. Feel extremely free to make your own version if you want though, I’d love to see how someone else might tackle this kind of task.
Now, for the Question of the Day, for whoever might have an answer:
I’m trying to spawn additional floors in my buildings, using a ForLoop a randomized amount of times, but I can’t figure out how to increment the position of each floor properly inside said ForLoop - they all move to the exact same position, and I’d really like them to spawn on top of each other, in a stack. It feels like I am missing something trivial here, but I can’t seem to crack it. Like, what I’d ideally want is some kind of node that lets me increment the position per loop. So, like, first floor gets moved 300, next one is moved 300+300, third is moved 300+300+300…you know?
