Ore Tuner

# Ore Tuner Ever wanted diamonds in huge veins, iron everywhere, or a world with no coal at all — without hunting through config files or writing a datapack? Ore Tuner puts ore generation in your hands, right where you make the world. Click the new Ore Generation button on the Create New World screen and you get a searchable list of every ore in your game — vanilla and modded. For each one you can dial in: 🪨 Vein size — how many blocks each vein contains 🎲 Frequency — how many veins generate per chunk 📏 Height range — the min/max Y the ore spawns at 🔀 Enable / disable — turn any ore's generation off entirely Per-world, not global Your settings are baked into the world you're creating and saved with it. Other worlds are untouched, and your global game files are never modified — so every world can have its own ore balance. Works with modded ores automatically Ore Tuner reads the ores from your game's world-generation data, so it picks up ores from other mods on its own — no per-mod patches or compatibility add-ons needed. How it works When you finish editing, Ore Tuner writes a small per-world datapack describing your changes and applies it before the world generates, so your tweaks take effect from the very first chunk. Everything is done through the game's own data system — no edits to vanilla generation. Requirements: Minecraft 1.21.1 · NeoForge
