An advanced in-game Minecraft Map Editor

Currently, only Fabric Singleplayer is supported.

Important! When in Keystone mode, moving the camera with your mouse works differently. In order to look around, either hold down right click and drag, or press right click to toggle mouse look. In addition, the in-game pause menu is disabled while in Keystone mode in order to let certain features work. To switch between normal gameplay and Keystone mode, press the 'Toggle Keystone' button (Default 'K')

Installation

  1. Install Fabric.
  2. Download Fabric API. Be sure to choose the correct file for your Minecraft version.
  3. Download Keystone from this page.
  4. Recommended: Download Starlight. This dramatically decreases lag spikes from lighting changes. This is not required, but is highly recommended.
  5. Put all files into your mods folder. This defaults to .minecraft/mods unless changed.
