uNmINeD is an easy to use and fast Minecraft world viewer and mapper tool. It can read Minecraft Java and Bedrock Edition world files and renders a browseable 2D overview map that you can export as an image or a web page.

It works on Windows, Linux and macOS.

See downloads, or scroll down for more screenshots, news and release notes.

There is a subreddit for posting beautiful map images, and we have a Discord server.

  • Added highlighter
  • Added Replace flowing water option to fix issues caused by random chunks of flowing water found in Bedrock oceans

This first release of the highlighter is pretty simple, but it can do a lot. It can be used to find blocks and biomes, to check block distribution, and to create interesting visualizations. Highlighters are saved with map settings, and can be used with the CLI.


Dripstones, lush caves and villages are highlighted

  • Brighter map
  • Added dark forest biome style
  • Added vanilla biome tints option to render vanilla biomes using in-game tints
  • Flat grass option now flattens out tall grass (to hide elevation shading and shadows cast by grass/flower/sapling/etc. blocks)
  • Moved/renamed configuration files (blockcolors.txt => config/blockstyles.txt)
  • Added support for *.blockstyles.txt config files (to customize block styles)
  • Added support for *.biometints.txt config files (to customize biome tints)
  • Added support for *.blocktags.txt config files (to add modded blocks)
  • Added support for *.colors.txt config files (to change map colors)
  • Added support for biome based coloring in *.blockstyles.txt
  • Added support for biome tints in *.blockstyles.txt
  • Fixed crashes

About the configuration files

uNmINeD loads configuration from the following files in the config folder:

  • Block styles from *.blockstyles.txt
  • Biome tints from *.biometints.txt
  • Color IDs from *.colors.txt
  • Block tags from *.blocktags.txt
  • Block tags from *.blocktags.js
  • Stylesheets from *.stylesheet.js
  • Biome number mappings from *.biomenumbers.java.json (for JE before 1.18)
  • Biome number mappings from *.biomenumbers.bedrock.json (for BE)
  • Block number mappings from *.blocknumbers.java.json (for JE before 1.13)

Good to know:

  • You can edit all these config files, and add your own.
  • uNmINeD looks for configuration files inside all subfolders and ZIP archives.
  • It is recommended to keep config files in subfolders (config/my-awesome-pack/blockstyles.txt), or in ZIP arhives (config/my-awesome-pack.zip), especially if you want to share them.
  • Postfixes “.java” and “.bedrock” can be added to any config file name to load them only for those world types (eg. my.blockstyles.java.txt will be loaded only for Java worlds).
  • Biome number mappings are not used for Java Edition 1.18 and newer versions.
  • Block number mappings are used only for Java Edition 1.13 and older versions.
  • Block numbers are not used for Bedrock Edition.
  • Config files in the default subfolder are loaded first, then the others in alphabetical order. Inside a subfolder or a ZIP archive, file names starting with “default.” are loaded first. If a value is defined in multiple files, the last value loaded will be used.

Other configuration locations:

  • Biome tints can be loaded from data packs in the game folder.
  • Block number mappings are loaded from level.dat in the game folder for Forge worlds before JE 1.13.

  • Added blockcolors.txt file to define custom block colors in an easy way
  • (WEB) Added custom.markers.js file for adding custom map markers

  • Added support for auto loading biome tints from data packs like Terralith
  • Added “Copy as SNBT” to NBT view
  • Slightly changed map colors to make it brighter
