World

Biome Range​

Defines the radius for biome repetition. By default, an area of 8192x8192 will encompass all the biomes in the world. If a biome does not appear within this area, it is excluded from the world. Biomes repeat beyond an invisible border. This feature can be disabled, preventing biome repetition.

warning

A small biome range may prevent certain structures from generating, especially if specific biomes are required. You can mitigate this issue by decreasing the structure modifier.

Island Distance​

Specifies the distance between two islands. If the_nether is selected as the start dimension, this distance is divided by 8.

Offset​

Determines the offset from coordinates (0, 0) for island generation. This can be utilized to generate islands centrally within .mca files.

Sea Height​

Sets the sea level in the world. Note that this does not affect the water height within the world but does influence spawn heights for entities like squids.

Structure Modifier​

Adjusts the spacing and separation of structures through a multiplier. Values for spacing and separation can be defined via a data pack. For more details, refer to the biome_source.structures.structures documentation 🔗.

  • Minimal spacing is set to 1 if the modifier reduces it below this value.
  • Minimal separation is set to 0 if the modifier reduces it below this value.
note

This configuration option requires a full restart if you have already joined a world.

Surface​

Settings for generating the overworld surface blocks. This follows the same format as the flat world generation settings 🔗 but will ignore the biome configuration. This can only be set for the overworld. If the surface generation is disabled, this setting will be ignored.

Single Biome​

Biome​

This specifies the biome for an entire dimension. You can choose the desired dimension, but if left as default, it will use the start dimension.

Allowed values:

  • default
  • overworld
  • the_nether
  • the_end
warning

Some structures require specific biomes to generate (e.g., Mansions require Dark Oak Forest). These structures will not be generated if you have only one biome.
