I'm trying to make really big ships (~5mil for armor outline) but when I'm halfway though, I have to wait 5-10 seconds after placing a single room on blueprint mode. It obviously gets even worse when testing ships. How do people make giant ships without needing to make coffee every time they place a room?
Also, how do people fill up so much space in giant ships? I usually fill space in my builds with armor, but that goes as well as you may expect.
