About this Mod

HB’s Ore Clusters and Regen

Short Overview

HB’s Ore Clusters and Regen is a mod that spawns large clusters of ore in the world in addition to the small vanilla ore veins players are used 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 finds an existing ore vein and creates a cluster 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.
  • In its base configuration:
    • Coal and iron generate in large clusters between 12x12x12 and 16x16x16
    • Deepslate diamond ore also spawns in smaller clusters deeper underground, and is more rare than coal and iron

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 — BUT the mod MUST be able to find a block of the specified in the world in order to know where to spawn the cluster. For example: you could create an iron_ore cluster, and add custom_mod:custom_nickel as one of the replaceableEmptyBlocks of the cluster.

Future Updates

Future updates will depend on feedback I receive on my Discord. Between porting to other versions, adding features, and working on other mods, it's important I prioritize based on feedback from active users.

Planned features include:

  • GUI for building configuration
  • Improved performance
  • In-game block “Sacrificial Altar” to reduce regeneration time for clusters
  • Compatibility for modifying concentrations of existing ore veins
  • Support for biome-specific configurations
  • Support for multiple configurations for identical ore types
