What is a BO3 file?

More Information

Minecraft objects consist of blocks that can spawn in your biomes. They can be ores, trees, dungeons, and other structures.

You must place the BO3 file in one of your two custom biome object (BOB) folders. The global folder allows all your TerrainControl worlds use the BO3 file. The local folder only allows one world to use the BO3 file.
