🗺️ ️Chunk Editor
An MCA-Selector like chunk map, in game.
Adds a Chunk Editor button to Minecraft's world edit screen. 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.

- Terrain rendering straight off the region files
- Respects data driven properties (biome tint, blocks, ...)
- 3 LoD layers based on zoom
- Every dimension the save has, including custom dimensions
- Deletes
region/,entities/andpoi/together (after backup)

Exporting
A selection & world-clip can be exported, containing all region, POI & entity data stored in vanilla format.
Selections are useful to export for later & repeated use.
Cross-compatible with standalone MCA-Selector tool
World Clips Storage: <instance>/chunkclips/
Selection Storage: <instance>/chunkclips/_selections/
Importing
All exports can be important in any world & any dimension (import may get cropped at Y).
The importer allows every version to be important, as long as it's lower than the target (e.g. 1.18→26.2) and chunks get auto upgraded.
❗ 1 Section = 16 Blocks
| Option | ??? |
|---|---|
| Sections | Range of sections that is imported (blank=all, -4:0=only deepslate layer) |
| Y-Offset | How much the import is shifted up/down (0=keep, -4=shift 4 sections down) |
| Existing Chunks | Keep=Existing chunks stay, Replace=New chunks override, Merge=Blocks merge |
-- Import Examples --
Reminder: A chunk has many 16x16x16 sections from top to bottom, that we can control (not blocks)
| Sections | Y-Offset | Result |
|---|---|---|
| (blank) | 0 | Full copy |
| 0:3 | 0 | Only blocks y 0..63 go in. Everything above & below is untouched (merge) or empty (replace) |
| (blank) | 1 | Full clip 16 blocks shifted up |
| -4:-1 | 4 | Take deepslate layer (y -64..-1) and rise it to stone layer (y 0..63) |
| 19 | 0 | Only the top section (y 304..319) |
