Hello, I'm new to fortress-craft but i caught on super fast(really love the interface and mechanics/physics). So anyways, i joined this guys world the other day and he had a bunch of invisible beamemitters as-well as large dervish blocks....etc. I Know this function isn't in the game, any ideas on how to replicate it or anything?. If anyone happens to figure this out let me know, because i would really like try it if it doesn't involve doing anything illegal or along the lines of hacking or anything like that. I'm pretty sure its just a glitch, that he some how did by making a custom block out of custom blocks in the workshop from slightly out side of it to make it invisible as a passive effect and figured out how to make it save, but I'm not sure because im having trouble replicating it.
