Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Forge only.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This is a client side mod that shows the borders of biomes with the press of a key. Compatible with the new nether biome generation!

Known Issues: On Fabulous! graphics, the borders do not show. Use Fast or Fancy while borders are enabled to see the borders.

Config Options:

View Range (horizontal and vertical)
2 Wall Colors, including transparency (highly recommended), depending on the temperature difference between biomes

Default keybind to toggle the border is 'B'

Here is an old showcase/tutorial of the 1.12.2 version by SuntannedDuck2: https://youtu.be/PyY-BwBDGbk

Do not install this on a server! It is purely client side, and may cause unexpected issues if installed on a server.
