Ore Minus
Customize Minecraft ore spawn rates by biome. Easily set multipliers for vanilla and modded ores (e.g., 2x diamonds in deserts, zero coal in ocean). Essential modpack ore distribution tool.
💎 Ore Minus
Control ore spawn rates in specific biomes. Make diamonds spawn 2x in deserts, disable coal in mountains, or customize ore distribution for your world.
🚀 Quick Start
- Install the mod and launch Minecraft
- Load a world to generate
config/ore_minus-template.txt - Copy entries from template to
config/ore_minus-common.toml - Edit multipliers and generate new chunks
⚠️ Important
- Only affects newly generated chunks
- Always configure both regular AND deepslate variants
- Use config/ore_minus-template.txt for all biome/ore IDs
- Works with modded content
- We advise you to stay < 1.5 chance rate
⚙️ Config Format
Edit config/ore_minus-common.toml:
biomeOreModifiers = [
"biome_id|ore_id|multiplier"
]
Example: Disable Diamonds in Oceans
biomeOreModifiers = [
"minecraft:ocean|minecraft:diamond_ore|0.0",
"minecraft:ocean|minecraft:deepslate_diamond_ore|0.0"
]
📈 Multiplier Guide
| Multiplier | Effect | Description |
|---|---|---|
| 0.0 | Completely disabled | No ore generation |
| 0.5 | 50% spawn rate | Rare |
| 1.0 | Default vanilla rate | Normal |
| 1.5 | 150% spawn rate | Very common |
| 3.0 | 300% spawn rate | too many ores |
🔧 How It Works
Controls ore spawn rates by modifying vein generation. Ore clusters stay natural - when you find diamonds, you still get 4-8 together.
