This project makes the overworld spawn void chunks, good for custom maps and such that you dont want to generate more default chunks

NoWorldGen is a simple Minecraft mod (Fabric, 1.21.11 only) that completely removes natural overworld terrain generation. With NoWorldGen, all newly generated areas in the overworld will be empty void—no terrain or structures will appear.
This makes NoWorldGen ideal for:
- Custom maps where you need the overworld to stay void except for what you build or import
- Premade maps that require strict control over world boundaries
- Servers or creative projects where you don't want any new terrain beyond your provided content
