Tips for Flat Building Worlds

You can also customize what generates on your flat surface. In the Biomes section, choose which biome type you want. In Surface Vegetation, disable trees and tall grass if you prefer a clean slate. If you want specific ores available, adjust the Ore Deposits settings to increase their frequency rather than mining for hours.

Once your world is created, you can continue tweaking generation rules in real time as you play—useful if you discover you want fewer caves or different biome patterns.
