Minecraft:Single Biome

File:Wooded Hills Vibrant Visuals.png

A single biome world set to forest or wooded hills generates an endless forest, even in oceans, mountains, or caves.

Single Biome is a Minecraft:world type or a vanilla Minecraft:world preset in which the entire Minecraft:Overworld consists of one Minecraft:biome. It is simple to customize, albeit very limited.

The customization screen for Single Biome

Single Biome uses a single fixed biome source for generating the Minecraft:Overworld with the default noise generator. Similar to the Minecraft:Default world type, this configuration generates a world with a bedrock floor at the Y=-64 lower height limit, and the rest of the terrain is generated on top of it. However, in contrast to the Default world type, the Overworld in a Single Biome world consists of only one biome.

The Nether and the End are unchanged from their Default world type counterpart. The Nether uses the multi-noise biome source and the End uses the Template:Code biome source.

Additionally, players can override any dimension with the same fixed biome source generation like Single Biome using a Minecraft:custom dimension data pack.

Custom biome

Single Biome world type allows players to choose a biome that the world generates in the terrain of the Minecraft:Overworld. Biome choice determines things such as terrain, vegetation, generated structures, and to some extent, mob spawning. Single Biome worlds can be customized to use any one of the available biomes, using only that particular biome for the entire world. The player can choose any of the existing biomes, including the Nether and the End biomes, and custom biomes from Minecraft:data packs.

This customization is available in the "Buffet world customization" menu, accessible by clicking the "Customize" button beside the world type selector in the world creation settings.

Using a biome from the Nether or the End to generate the Overworld results in a world with their structures and characteristics, albeit very incomplete. For example, Minecraft:warped forest does not generate any warped trees, but still generates fogs, particles, and Minecraft:nether fortresses. This is caused by a bug where the biome surface and terrain is different from their own dimension.<ref>Template:Bug</ref>

Server operators can set a Single Biome world type by setting level-type=minecraft:single_biome_surface in Minecraft:server.properties.

Bedrock Edition

Code for the Single Biome world type exists in Bedrock Edition; however, it is inaccessible through the game's GUI. It can only be accessed by editing the world's level.dat file using external programs.<ref>Generate custom flat and single biome worlds on Bedrock!</ref> This code supports every biome in the game, including unused biomes. In general, generation is the same as in Java Edition.

In Bedrock Edition, Single Biome has a few quirks such as:

• Just like in regular worlds, Minecraft:mineshafts, Minecraft:ruined portals, and Minecraft:strongholds generate in every biome.
  • This does mean that it is possible to get wood and enter the Minecraft:End regardless of the chosen biome, unlike Java Edition.
• Single Biome affects the Minecraft:End but not the Minecraft:Nether. World generation in the End is glitched with many Overworld features between the End islands.
• Minecraft:Oceans and Minecraft:rivers when inside of a Nether biome have a checkerboard-like pattern of water and lava.
• Minecraft:Structure generation cuts off at Y-level 256 when in a Nether or End biome.
