just place in base and run it with /map glitch.
Small glitch I knew existed in the rendering engine. On this map are 7 cubes, in a configuration with one at the center and the other 6 touching it's six sides.All six of them have been "bent" , and the central cube is totally invisible! To prove it exists, I have filled it with MAT_WATER, so when you fall in you can see the water. Hope you enjoy, terlmann.
