About this Mod

💎 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

  1. Install the mod and launch Minecraft
  2. Load a world to generate config/ore_minus-template.txt
  3. Copy entries from template to config/ore_minus-common.toml
  4. 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.

Frequently Asked Questions

Ore Minus server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Ore Minus compatible with forge?

Ore Minus officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Ore Minus – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Ore Minus consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
