Biomes

Biomes let you create a new environment with its own terrain, plants, blocks, structures, creatures, sounds, and atmosphere. They are available for Java and Bedrock Edition.

How to Create a Biome#

1. Open Create Biome.
2. Choose your Minecraft edition and version.
3. Describe the environment and how players encounter it.
4. Add optional reference images, textures, audio, or Studio assets.
5. Generate the biome and test it in a fresh world or unexplored chunks.

Biome creation supports up to five reference images, five texture images, and five audio files. Direct 3D-model attachments are not available in the Biome creator.

What to Describe#

Useful details include:

• Terrain: flat, mountainous, floating, underground, coastal, or filled with islands
• Ground and plants: surface blocks, trees, flowers, grass, fungi, or other foliage
• Atmosphere: colors, fog, particles, ambient sounds, weather, and mood
• Content: mobs, ores, structures, landmarks, resources, and hazards
• Rarity: common, uncommon, rare, or restricted to a particular region
• Gameplay: why players visit and what they can find or accomplish there

Example:

Create a rare moonlit marsh with dark teal water, pale willow trees, glowing ground flowers, heavy blue fog, and quiet insect sounds. Small ruined shrines should appear on islands. Add a shy luminous frog that drops glow gel used to craft lantern blocks.

Testing World Generation#

Minecraft normally generates biomes only when it creates new terrain. For a reliable test:

1. Create a new world, or travel to chunks that have never been loaded.
2. Check that the biome can be found and entered.
3. Test structures, mobs, resources, and sounds separately.
4. Use a Mod Edit if the biome is too common, too rare, or missing an expected feature.

Generation and testing can take longer than a focused item or mob because Minecraft must build new terrain.
