# How to Reset Specific Minecraft Chunks with MCA Selector (/docs/minecraft/reset-chunks)



MCA Selector lets you delete specific chunks so they regenerate with fresh terrain. This is perfect for regenerating specific areas after a Minecraft update without losing builds elsewhere.

<div className="fd-steps">
  <div className="fd-step">
    Download your world [#1-download-your-world]

    Access the [XGamingServer panel](https://panel.xgamingserver.com), stop your server, and [download your world](/docs/minecraft/download-world).
  </div>

  <div className="fd-step">
    Open in MCA Selector [#2-open-in-mca-selector]

    Download and open MCA Selector. Go to File → Open and select your world's `region` folder.
  </div>

  <div className="fd-step">
    Select chunks to reset [#3-select-chunks-to-reset]

    You can select chunks by:

    * **Clicking** individual chunks on the map
    * **Drag-selecting** a region
    * **Using filters** (Tools → Filter Chunks) to auto-select by criteria

    Useful filter for regeneration:

    ```
    InhabitedTime < 00:01:00
    ```

    This selects chunks players spent less than 1 minute in.

  <div className="fd-step">
    Delete selected chunks [#4-delete-selected-chunks]

    Go to Selection → Delete Selected Chunks (or press Delete).
  </div>

  <div className="fd-step">
    Re-upload the world [#5-re-upload-the-world]

    Upload the modified world back to your server via `Files`.
  </div>

  <div className="fd-step">
    Start your server [#6-start-your-server]

    Deleted chunks will regenerate with current world generation when players explore them.

    > 💡 **Tip:** Use this after major Minecraft updates to get new biomes and structures in unexplored areas while keeping your builds intact.

    > ⚠️ **Warning:** Deleted chunks lose all blocks, chests, and entities. Double-check your selection before deleting. Create a backup via `Backups` first.

    > 📝 **Note:** Chunk borders between old and new terrain may look unnatural (terrain cliffs). This is normal at the boundary between different world generation versions.
