MCA Selector is an external tool for Minecraft Java Edition that lets you visualize, select, export, or delete world chunks and region files.
Common uses: trim large worlds, remove corrupted chunks, and export/import regions.
Key features:
- Top-down map view — visual overview of regions and chunks for quick navigation and selection.
- Customizable overlays — display per-chunk values as color gradients with configurable min/max to visualize world data.
- Dimension switching — open/edit Overworld, Nether, and End (DIM-1/DIM1) region folders.
- Select/edit chunks individually or in groups
- Powerful chained filters — select chunks/regions by data version, last updated time, player inhabited time, coordinates, modification date and more (even scripting custom filters); multiple conditions can be combined for precise queries.
- Chunk Editor — view and edit the full NBT structure of a chunk, including POI and entity data; supports rename, add, delete, and drag‑and‑drop moves.
- Easy chunk import/export — copy chunks from one world to another.
- NBT Changer — modify specific NBT values directly in world files.
- Chunk regeneration (delete to let Minecraft regenerate with new terrain)
Note that you should always back up your world before editing it with MCA Selector.
