World preset

This feature is exclusive to Java Edition.

 

World preset is used to determine what dimensions a new world will have, which can be customized by a data pack. When creating a new world, on the "World" tab, it is possible to choose which world preset to use, or not use any world preset.

Usage

When opening the "World" tab for the first time, the "World Type" button is displayed as "Default" which means that at the moment the new world does not use any world preset, but uses three vanilla dimensions by default, and it also tries to read the dimension files from the dimension folder of the data pack. Note that a data pack can modify these three vanilla dimensions or add new dimensions with the dimension files, but cannot delete the vanilla dimensions.

Once the player clicks the "World Type" button, the game will use the world preset to determine the dimensions of the new world, no longer using the dimension folder. Changing the button back to "Default" will use the minecraft:normal world preset, instead of the original default state. However, without the data pack, the default state is exactly the same as the "Default" preset (minecraft:normal).

The game also does not use world presets if custom world settings are imported.

List of world presets

Type	Description	Image
Default	Various landscapes in the Overworld are generated with biomes.
Superflat	This world preset makes the Overworld completely flat. By default, the terrain consists of one layer of bedrock, two layers of dirt and one layer of grass; the surface is therefore at Y=-60. Mobs spawn normally; slimes are prevalent. It can be further customized through the "Superflat World Customization" screen and superflat level generation preset, which allow the player to change terrain layers, spawn trees, and generate larger villages, strongholds, etc.
Amplified	The Overworld dimension generates many large mountains that dwarf even the mountains biomes seen in default world types and often reach the world height limit. Due to extremely steep cliffs and unforgiving terrain, careless players may have difficulty surviving. Certain biomes (i.e. oceans and rivers) may see no obvious change in height. Villages still spawn in this world type regardless of how flat the ground is, causing the buildings to generate in bizarre ways.
Large biomes	The size of the biomes in the Overworld is roughly 4x larger along the X and Z axes, which results in biomes with 16 times as much area.
Single biome	There is only one biome in the Overworld. This biome defaults to Plains and can be selected by the player at the time of world creation.
Debug mode	A world preset containing all of the block states laid out in a grid at layer y=70 for convenient viewing. It can be accessed by holding down the ALT key while cycling through the world types. In this world type, there is a floor on y=60 made of barriers and the player cannot place or destroy blocks.
