Dynamic Ore Veins

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!
