Hey, minimaps aren't really "made," they are created automatically whenever you load your map in a game mode that uses mini maps. You can however change the height of the minimap so that it shows your layout as clear as possible, and not blocked by the ceilings of your map. There is "/minimapheight [value]" to change it, but the easiest way is to float to a spot on your map just underneath a ceiling, and use "/minimaphere". Of course you would need to save map and load it in CTF or something to see if it worked. Hope this helps
