About

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.
