Guides › World
A biome is a region of the world with its own climate, ground and look: deserts, jungles, snowy plains and so on. A custom biome adds a new one, with the blocks, plants, colours and terrain you choose.
The Biome editor in Addon's Studio sets it all with simple choices. Your biome takes over part of a vanilla biome, so it blends into normal world generation.

Step by step
Add a Biome
In your project, tap Add item and choose Biome. Give it a name and an ID.
Pick the climate
Choose a temperature from Frozen to Hot & dry, and how much it rains. Frozen biomes get snow; hot and dry ones never rain.
Choose the ground
Pick the top block, what's under it, what's deep down and the sea floor.
Shape the terrain and add plants
Choose Flat, Gentle, Hills, Mountains or Extreme peaks. Under Plants & decorations, add blocks like flowers or grass and how many appear per chunk.
Set the colours
Pick colours for the sky, fog and water.
Choose where it appears
Pick which vanilla biome it replaces part of, and how much. 0.3 replaces about a third of it.
Tips
- Biomes only appear in newly generated chunks, so explore somewhere new or make a new world.
- Your biome shows up in the biome list of your mobs and structures, so they can spawn in it.
- Try unusual colours, like purple water and pink fog, for a magical biome.
- Mountains or Extreme peaks with a Frozen climate make dramatic snowy scenery.
Questions
Why can't I find my biome?
Biomes only appear in newly generated chunks. Explore somewhere new or make a new world. A higher How much it replaces value also makes it easier to find.
Which Minecraft version do I need?
Custom biomes need a recent version of Bedrock. Add-ons made with Addon's Studio are built for Minecraft Bedrock Edition 1.26.50 or newer.
Can my custom mobs spawn in my biome?
Yes. In your mob's Natural spawning settings, your custom biomes appear in the biome list. Structures work the same way.
