About this project
What does Cave Spelunking add?


- Cave-Focused Ore Generation: Ores only appear next to specific cave blocks (like air, water, and lava), ensuring a more natural placement.
- Customizable Ore Spawn Chance: Adjust the global spawn rate of ores with a simple percentage slider. Decrease for a challenge or keep it balanced.
- Hidden Ore Chance: Control the likelihood of ores generating outside designated cave walls. Default is 10% for a more cave-focused experience.
- Vein Density Modifier: Fine-tune the density of ore veins like iron and copper with a multiplier. From disabling veins entirely to increasing their abundance, the choice is yours.
- Ore Inclusion/Exclusion List: Specify ores to exclude (or include, with inversion) from the cave-only restriction, ensuring compatibility with modded ores.
Requires Cuboard dependency to be installed in newer versions

- Set the chance for ore to spawn outside of caves
- Set which blocks ore is allowed to spawn next to, default is air, liquids and other ore blocks
- Reduce the chance of all ore to spawn globally
- Set the density of ore veins(iron/copper)
- Set which ores are affected/excluded
