Can I just build my own buildings and then get the colonists to “move in”?.I have a “ /blueprints/clients/” folder, what is that for?.How do I install custom schematics I just downloaded?.You can use the scan tool and scan ANY building or structure you like in singleplayer or multiplayer and then have your Builder build it for you (provided that you give them all the materials needed, of course). Schematics are files containing block and entity information of a certain area a player scanned with the Scan Tool in-game.
