Config

[NBT Compound / JSON Object] config
- [String][NBT Compound / JSON Object] default: One placed feature (an [String] ID, or a new [NBT Compound / JSON Object] placed feature definition) — Used if none of the below features are chosen.
- [NBT List / JSON Array] features: (Required, but can be empty) A list of placed features from which to randomly choose.
  - [NBT Compound / JSON Object]: A feature and its corresponding chance.
    - [String][NBT Compound / JSON Object] feature: One placed feature (an [String] ID, or a new [NBT Compound / JSON Object] placed feature definition)
    - [Float] chance: The chance of this feature being chosen. Value between 0.0 and 1.0 (inclusive).

The defined features can either reference a placed feature directly, or can reference a configured feature by nesting another "feature" node within. For more information, see this page on the two allowed types of feature definitions.
