Hey guys! I've seen people try to make a sky island kind of map before, and it's pretty good, except below the island, there is land! I'm going to tell you how to make a void world in Minecraft. Incase you were wondering, a void world is a world with absolutely nothing in it. It's just the sky and the void. I will also tell you how to spawn in a block so that you can actually build stuff in the void world. This is how you do it:

Step 1: Go to singleplayer a click "Create New World"

Step 2: Click "More World Options"

Step 3: Click "World Type: Default," then click "Customise"

Step 4: Click "Presets"

Step 5: In the box at the top with the numbers in it, delete everything and type in "00"

Step 6: Click "Use Preset," then click "Done," then click "Create World"

MAKE SURE YOU ARE IN CREATIVE SO THAT YOU CAN FLY!!!

Now, how to get a block in the world to build off of. This is the command: (this will do stone) /setblock ~ ~-1 ~ stone

Thanks for reading! Merry Christmas and remember to diamond! :D
