Dynamic Ore Veins
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Dynamic Ore Veins is an API that exposes Minecraft's large ore vein generation through JSON! With this mod, you can develop datapacks to:
- Create custom large ore veins
- Give them unique shapes and conditions
- Make biome- and dimension-dependent veins
- Disable vanilla veins
With these tools, you can create as many large vein types as you want! Whether rich in minerals or simply aesthetic, they are at your disposal!
