TerraBlender 9minecraft Mod helps custom biome mods work together in the same world. It shares world space between different mods and the base game across the Overworld, the Nether, and the End. New lands blend with existing mountains, rivers, and oceans without overwriting each other. It also manages custom ground blocks so every environment looks right. This library adds no items or mobs on its own, but works in the background when your favorite biome mods require it.
