Vanilla Minecraft offers you a world height of 384. For most people, this limit is enough. But if you want to build large scale structures, this limit may not be enough. 1024 Mod is here to increase the world limit to 1024 blocks. This means, you will be able to build from Y levels – 512 to 512. The mod also replaces bedrock with reinforced deepslate. You will be able to break this deepslate and build under this layer.
Features:
- Increases the world height from 384 to 1024.
- Usable Y-levels from -512 to 512.
- Replaces bedrock layer with reinforced deepslate.
