About MCA Selector
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:
o Top-down map view -- visual overview of regions and chunks for quick navigation and selection.
o Customizable overlays -- display per-chunk values as color gradients with configurable min/max to visualize world data.
o Dimension switching -- open/edit Overworld, Nether, and End (DIM-1/DIM1) region folders.
o Select/edit chunks individually or in groups
o 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.
o 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.
o Easy chunk import/export -- copy chunks from one world to another.
o NBT Changer -- modify specific NBT values directly in world files.
o 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.

| Release notes | Updates for Minecraft 26.3 and new zoom options! Join our Discord: [](https://discord.gg/h942U8U) Buy me a coffee: [](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=3PV2GDWZL8HCA) Details • Added low detail zoom levels: • Can be configured in the settings. • Improved coordinates rendering (display coordinates on the map edge, or on the map directly, or a mix of both depending on zoom level, all configurable in the menu). • Structure icons are only rendered in high detail zoom levels. • The Settings dialog is now more responsive. • The Render Settings now have a Set default button to make the current render settings persistent. This will apply to any new world that doesn't have custom render settings set yet. • The language selection dropdown is now sorted alphabetically. • The Render Height slider (in the menu bar) is now more responsive. • Both the Compression filter and Compression field now support the unsigned byte value in addition to the internal enum name. • Added RemoveLightingInfo field. This removes the BlockLight and SkyLight data, and sets isLightOn to 0 to force Minecraft to recalculate lighting info. • ReplaceBlocks now removes BlockLight and SkyLight and sets isLightOn to 0. • Updated mappings, rendering and parsing for Minecraft 26.3. • Fixed a bug in the mapping generator to use the first available color as the default color, and added javadoc for its main. |
