How to Adjust Global Ore Spawn Rates and Strip Mining Odds

If hunting for resources exclusively on cave walls feels too punishing—or not challenging enough—you can customize how strictly ores stick to caves and how many spawn overall. Because these options govern terrain generation, any adjustments will only apply to newly generated chunks or fresh worlds.

Changing Global and Non-Cave Rates

1. Open your mod settings menu or locate the mod's configuration file in your game folder.

2. Find the global spawn rate percentage slider. Decrease the percentage if you want a tougher survival challenge with scarce minerals, or leave it higher for a balanced experience.

3. Locate the setting that controls the likelihood of ores generating outside designated cave walls, which defaults to 10%.

4. Raise this value above 10% if you want traditional strip mining through solid rock to yield more resources, or lower it further for a strictly cave-focused playthrough.

5. Save your configuration changes, load your world, and travel into unexplored territory so new chunks generate using your updated ore rates.
