HB’s Ore Clusters and Regen
ATTENTION ensure you are using the most recent version of Balm. Especially on 1.21.1.
HB’s Ore Clusters and Regen is a mod that spawns large clusters of ore in the world without modifying the small vanilla ore veins players are accustomed to. These ore clusters also regenerate (configurable) after several days so the clusters can be harvested again, boosting resource supply and incentivizing the player to set up multiple small bases around the world, and interconnect them.
Why would you want this?
- Finding a cluster of ore is a rewarding discovery that makes exploring caves more fun
- If you think Gregtech Ore Generation style is cool and you also don’t want to lose the traditional vanilla ore veins
- Regenerating clusters incentivize players to create a true secondary mining base, and makes choosing the location of a base more important
Which ores regenerate? How big are the clusters? What if I like normal Minecraft mining?
- This mod does not modify the existing vanilla ore generation at all — it (rarely) chooses an existing ore vein and creates a large cluster of ore out of it.
- Vanilla mining is great and should remain a core part of the game!
- All aspects of the clusters are configurable via a JSON config file. See the section below or view my GitHub page.
Compatibility with other mods
- This mod works with Terralith, Tectonic, Biomes O’ Plenty, and all world generation mods
- It can form clusters for any block naturally generated in the world (including modded ores, beehives, wood etc. but does not necessarily work with block_entities, which may have more detailed configurations)
- The mod can add new ores to world gen on its own — BUT only if the ore is added as a "companion block" to a cluster with a block type that exists in world gen already
- For example, you could configure iron clusters to spawn with a modded "nickel_ore"
