Design Minecraft Bedrock biomes, preview surface materials and export behavior and resource packs.
How to use this tool
- Choose a starting biome and give it a unique namespace.
- Set surface blocks, climate and generation settings; inspect the material preview.
- Review validation messages and export the packs for testing in a new world.
Output: Biome JSON, behavior packs and resource packs.
Use the validation results as a starting point, then test the exported files in your target Minecraft version. Keep a backup before importing packs into an existing world.
