'''Noise settings''' are for generating the shape of the terrain and noise caves, and what blocks the terrain is generated with, stored as [[Minecraft:JSON]] files within a [[Minecraft:data pack]] in the path {{cd|data/<namespace>/worldgen/noise_settings}}, and are used with the {{cd|minecraft:noise}} generator in a dimension. Vanilla settings include {{cd|minecraft:overworld}} for normal [[Minecraft:Overworld]] generation, {{cd|minecraft:amplified}} for [[Minecraft:Amplified]] Overworld generation, {{cd|minecraft:nether}} for regular [[Minecraft:The Nether|Nether]] generation, {{cd|minecraft:caves}} for Cave (Nether-like generation but with Overworld [[Minecraft:terrain features]]) generation, {{cd|minecraft:end}} for regular [[Minecraft:The End|End]] generation, and {{cd|minecraft:floating_islands}} for Floating Islands (similar to The End outer islands) generation.

== Noise router ==
{{Main|Noise router}}

The '''noise router''' is a collection of [[Minecraft:density function]]s. Density functions compute a value for each block position. They are used for terrain generation, biome layout, aquifers, ore veins, and more.

== Surface rule ==
{{Main|Surface rule}}

'''Surface rules''' are used to determine the block for each solid position of the terrain. Noise settings contains one root {{nbt|compound|surface_rule}} field that contains all the logic for placing the different surface blocks.

== Defaults ==

These are the default settings for some vanilla presets. For brevity, some fields are summarized or omitted entirely; the vanilla data pack's <code>minecraft/worldgen/noise_settings</code> directory has them in full.

Amplified and large biomes are the same as Overworld generation, but the {{nbt|compound|noise_router}} is adjusted.
