The customization screen for Buffet.

Buffet is a world type in which the entire Overworld consists of one biome (Single Biome). It is considered a substitute for the old customized world type. By comparison, the Buffet world type is simple to customize.

World types[]

There is one world type as part of Buffet:

  • Single Biome: Uses the regular generation settings in Overworld: the world generates with a bedrock floor at the Y=-64 lower height limit, and the rest of the terrain is generated on top of it. However, there is only one biome in Overworld, which is selected by the player.

Custom biomes[]

Buffet world types allow the player to choose a biome that the world uses in generating terrain of Overworld. Biome choice determines things such as terrain, vegetation, generated structures (if applicable), and to some extent, mob spawning. Buffet worlds can be customized to use any one of the available biomes and use only that particular biome for the entire world. The player can choose any of the existing biomes, including technical biomes (such as different End island types).

Attempting to use custom biomes from data packs causes a crash.

Trivia[]

  • If the Nether or The End is used as the world generation, then the sky would appear, as if it is a mixture of the Overworld and the dimensions.
