If you want to Build custom biomes in Minecraft then you must follow these instructions given in this post below:

  • Start by creating a new world in Minecraft and selecting the “Customized” option.
  • Using the terrain generator settings, adjust the parameters for the biome you want to create, such as temperature, rainfall, and vegetation.
  • Use the worldpainter tool In your Minecraft APK Download  to shape the terrain, add or remove hills and mountains, and create lakes and rivers.
  • Use the biome brush to paint the area with the desired biome. This will change the appearance of the terrain and the types of trees and plants that will grow there.
  • Add custom structures and mob spawning areas to the biome. You can use mods or resource packs to add new structures and mobs to the game.
  • Test the biome by exploring it and making sure that everything looks and behaves as you intended.
  • Once you are satisfied with the biome, save the world and share it with others or use it in your own Minecraft adventures.

Note: Some of the steps may require additional software or mods to be installed on your computer. It’s also important to keep in mind that building custom biomes can be complex and time-consuming, so be prepared to put in a lot of work.
