⬇ Download on Modrinth💎 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.
