What it does

Chunk Editor - MCA-Selector adds a chunk editor inside the game, modeled on the MCA-Selector tool. A Chunk Editor button in the World Menu of the world edit screen opens a map of the whole world, where chunks can be selected by hand or by criteria such as playtime, staleness, distance from spawn and whether the game would regenerate them on the next visit. Selected chunks can be deleted, and the mod can delete region entities and points of interest together after making a backup.

The mod renders terrain straight from region files at high speed, using three level-of-detail layers that change with zoom. A max-height slider cuts the view down, which lets a player look under the Nether roof. Overlays and heatmaps show numeric ranges, either set manually or calculated automatically, along with categorical overlays such as biomes in hashed colors, block counts and custom NBT values. Dimensions are saved as well, including custom dimensions.

The mod is open source under the GNU Affero General Public License v3.0 only, and its source code is public. It is published for Fabric, NeoForge and Quilt, with files for 26.1.2 as the latest build. Fabric API, Fabric Language Kotlin and KotlinLangForge are required, and Better Worlds - Map Finder and Chunky are optional.

Key features

  1. Chunk map in game

    A map of the world shows each chunk, so chunks can be inspected without leaving the game.

  2. Criteria-based selection

    Chunks can be selected by hand or by inhabited time, staleness, distance from spawn and other criteria, then deleted or extracted.

  3. Layered terrain rendering

    Terrain is drawn directly from region files with three level-of-detail layers that switch with zoom, and a max-height slider cuts the view down.

  4. Overlays and heatmaps

    Numeric and categorical overlays, including biome tints and custom NBT paths, are drawn over the map with hover information for each region.

What the author says

An MCA-Selector like chunk map, in game. Adds a Chunk Editor button to Minecraft's world edit screen (World Menu -> Edit -> Chunk Editor). View the whole map & select chunks by hand or by criteria (playtime, staleness, distance from spawn), and delete them so the game regenerates them on the next visit.
