How to Change the World Type on Your Minecraft Server

Switch your Minecraft Java server to flat, large biomes, amplified, or single-biome world generation.

The level-type setting in server.properties controls how Minecraft generates terrain — normal, superflat, amplified, large biomes, or single-biome. Changing the level-type only affects newly generated chunks, so to apply it to your whole world you must delete (or replace) the existing world folder.

World Type Values

ValueDescription
minecraft\:normalStandard world generation (default)
minecraft\:flatSuperflat — single layer of bedrock + grass, no terrain
minecraft\:large_biomesSame biomes as normal, scaled 16× larger
minecraft\:amplifiedExtreme terrain heights (mountains up to Y=256)
minecraft\:single_biome_surfaceEntire world is one biome

Version note: Minecraft 1.19+ uses the minecraft\: namespace prefix. For older versions (1.18 and below), use uppercase values like FLAT, LARGEBIOMES, AMPLIFIED.

Change the World Type

Stop the server

In the XGamingServer Panel, open Console and stop your server.

Back up the existing world

Go to Backups in the sidebar and create a backup before deleting anything. This is your safety net if you change your mind.

Edit server.properties

Click Files in the sidebar and open server.properties in the server root. Find the level-type line and change it:

level-type=minecraft\:flat

Click Save Content.

Delete the world folders

In Files, delete the world/ folder (and world_nether/, world_the_end/ if they exist on Spigot/Paper). The new level-type only takes effect on freshly generated worlds.

Warning: This permanently deletes all builds, structures, and player progress in the world. Make sure your backup from step 2 completed first.

Start the server

Start from Console. The server will generate a new world using the level-type you set.

Superflat Customization

Superflat worlds support custom layer presets. Set generator-settings in server.properties to a preset string — see Create a Superflat World for full preset syntax.

Common Issues

ProblemFix
World still looks the sameThe old world/ folder wasn't deleted — Minecraft loaded the existing one
level-type value ignoredWrong format for your version. Use minecraft\:flat on 1.19+, FLAT on older versions
Amplified world causes lagAmplified terrain is CPU-intensive — pre-generate chunks with Chunky
Single-biome world won't generateRequires generator-settings with the biome ID (e.g., minecraft:plains)

Tips

  • Amplified worlds are stunning but eat CPU during generation. Pre-generate with Chunky overnight before letting players explore.
  • Flat worlds are ideal for creative build servers, minigames, and parkour maps.
  • Large biomes is great for survival servers where players want long expeditions across each biome before reaching the next.
  • The level-type only applies on first generation. Once a chunk exists, its terrain is locked in.
