How to PERMANENTLY delete chunks in Minecraft

Solution 1:

If it is a completely void world you seek, there is just the thing already in the game!

1. Click "Create New World"
2. Click "More World Options"
3. Change the World type from "Deafult" to "Superflat"
4. Click the "Customise" button below it
5. Click the "Presets" button
6. Scroll down the list until you see the preset "The Void"
7. Click on "The Void" preset
8. Then press "Use Preset"
9. Click "Done"
10. Change any other settings you would like
11. Click "Create New World"!

You will spawn on a 32x32 platform made out of stone with random blocks of cobblestone mixed in. The entire world is completely void, no Bedrock, no structures, Nothing.

Hope this helps :)
