i think he means, like if someone melee you into a bulding it will get destoryed/break, but any beams and stuff... will not destory it or will if u hit alot of beams into it, maybe try go to breakable then the "flags" tag, and tick Instant Crowbar, i dono if it will work, but its worth a try right? hm if it works, tell me ;p and u can do it to as many as u like, just could get a bit laggy when playing..
