Design a Cave-Heavy World for Mining and Exploration

Maximizing Cave Generation

If you love caving and want a world packed with underground systems, customize cave generation to suit your playstyle.

1. Start a new world and select Custom as the world type

2. Click Edit rules and go to the Caves category

3. Increase cave size parameters to make caverns larger and more expansive

4. Boost cave frequency or density settings so more caves generate throughout the world

5. Adjust underwater cavern settings if you want flooded cave networks

6. Click Generate Preview to inspect the underground layout

7. Create your world

Balancing Resources and Challenge

Larger caves mean more exposed ores, so consider increasing ore deposit values in the Ore Deposits section to avoid running out of resources too quickly. You can also reduce terrain height in the Terrain category so caves are closer to the surface—less digging to find them.

If caves feel too cramped or too open after exploring, you can edit these rules in real time while playing. Simply open the rules editor again and adjust cave parameters; newly generated chunks will reflect your changes immediately.
