Medium Biomes

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 Data pack only.

Minecraft 1.21.9–26.2Newest
Minecraft 1.19–1.21.8

⬇ Download for 1.21.9–26.2 ⬇ Download for 1.19–1.21.8

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.

Medium biomes

Medium Biomes is a Minecraft datapack that adjusts world generation by introducing a biome scale between default and large biomes.

This creates a more balanced terrain layout, where biomes are neither too small and fragmented nor excessively large and repetitive. The result is a smoother exploration experience with improved biome transitions and more coherent world generation.

Features

Adds a biome scale between default and large biome generation
Creates more cohesive and naturally distributed biomes
Improves exploration by reducing excessive biome fragmentation
Only affects newly generated chunks

Installation

Download the datapack
Move the datapack inside .minecraft/saves/<world>/datapacks (How to find .minecraft?)
Reload the world or run /reload
