An example sample of the minecraft:continentalness noise

A noise is a technical Minecraft:JSON file that can be referenced by a Minecraft:density function and Minecraft:surface rule. They are stored within a Minecraft:data pack in the folder Template:Cd.

In addition to being called by density functions and surface rules, there are also some noises with hard-coded usage:

• Template:Code: Affects the surface layer thickness in surface rules.
• Template:Code: Used as the thickness of additional surface layer in surface rules.
• Template:Code: Used to generate badland terracotta bands in Template:Code surface rules.
• Template:Code, Template:Code, Template:Code: Used when generating badland hoodoos in Template:Cd biome.
• Template:Code, Template:Code, Template:Code: Used when generating iceberg Minecraft:terrain feature in Template:Cd and Template:Cd biomes.

JSON format

• Template:Nbt: Root object.
  • Template:Nbt: First octave. If Template:Nbt in the noise settings is true, it must be an integer less than or equal to 1, otherwise the value range is not unlimited.
  • Template:Nbt (optional): A scaling factor to apply to each octave. The number of elements in the list must match Template:Cd. If not specified, it defaults to 1.0.
    • Template:Nbt: A double value for a sub-noise.
  • Template:Nbt: A scale factor to apply to the noise output. It must not be negative.
  • Template:Nbt: The number of octaves to sample. Value between 1 and 32 (inclusive).
  • Template:Nbt: Controls how the output amplitude should be normalized. If Template:Cd, Template:Cd is the expected amplitude of the output (i.e., 99.7% of all samples in Template:Cd). If Template:Cd, the base amplitude is instead the amplitude of the first octave. If Template:Cd, it inherits the same normalization behavior as expressed by the previous format. If not specified, it defaults to Template:Cd.
