How to Create a Superflat World on Your Minecraft Server

Learn how to create a superflat world with custom layers for building, redstone, or creative servers.

A superflat world generates completely flat terrain, making it ideal for building servers, redstone testing, PvP arenas, and creative mode.

Creating a Superflat World

Stop your server

Access the XGamingServer panel and stop your server.

Set the level type to flat

Go to Files, open server.properties, and set:

level-type=minecraft\:flat

Configure custom layers (optional)

To customize the layers of your flat world, set the generator-settings field in server.properties. The format is JSON (1.13+):

generator-settings={"layers":[{"block":"bedrock","height":1},{"block":"stone","height":3},{"block":"dirt","height":3},{"block":"grass_block","height":1}],"biome":"plains","structures":{"stronghold":{}}}

Delete the existing world

Go to Files and delete the world folder to generate a fresh world with the new settings.

⚠️ Warning: This permanently deletes your current world. Create a backup via Backups first.

Start your server

Start the server. A new flat world will generate.

Common Presets

Classic Flat (default):

{"layers":[{"block":"bedrock","height":1},{"block":"dirt","height":2},{"block":"grass_block","height":1}],"biome":"plains"}

Redstone Ready (stone slab surface):

{"layers":[{"block":"bedrock","height":1},{"block":"stone","height":52},{"block":"sandstone","height":3}],"biome":"desert"}

Void World (empty, for custom builds):

{"layers":[{"block":"air","height":1}],"biome":"the_void"}

💡 Tip: The default superflat world is only 4 blocks deep, which means mobs can spawn in caves below. Use a deeper stone layer if you want to avoid this.
