About this project
What does Cave Spelunking add?


Cave Spelunking allows you to configure how ore is spawned, you can set the percentage of ore that is allowed to generate outside of caves.
The cave detection works indirectly by preventing ore from spawning when it is not next to specified blocks, by default air/water/lava/other ore.
**Ore veins can be configured seperatedly, allowing you to modify their size.
Additionally you can configure how much ore in total is generated, e.g. you can set it to only generate 70% of normal minecraft ore amounts.
And it allows you to configure Minecraft's hidden ore mechanic, where minecraft actively hides spawned ore inside a wall 1-2 blocks wide, when they are visible from a cave.**
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
