- 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.
