Info:

Ore Tweaker is a super lightweight utility mod that allows you to customize and tweak the underground generation in Minecraft. The mod can be both installed on a server or a client.

 I strongly recommend using World Stripper to debug and test your ore generation when using this mod


Ore Tweaker

A Wiki for Ore Tweaker 3 is being worked on right now. For more help ask on Discord.

As of May 5, 2021 - Ore Tweaker 2.x.x and 3.x.x is the only supported versions of Ore Tweaker.

Ore Tweaker was rebuilt from the ground up to create a improved user experience, make the mod easier to use and support modern versions of Minecraft.

Due to changes to world generation after Minecraft 1.12 and a huge Forge rewrite I decided to start all over again and develop a sequel from scratch.

The new version of the mod has a ton of new features listed below and non of those features will be backported. The mod also now uses JSON files to configure the world generation.

🔴Server Sided
⚪️JSON file config
🟢Generated templates
🔵Works with most modded ores 
🟤Extensive support for popular mods by request
 

Configuration:

Example of how the OreTweaker data files can be configured:

  • "ore" - The registry name of the block to generate. Can found by pressing F3 + H and hover over in inventory
  • "filler" - What block to replace with the "ore", usually stone or nether rack
  • "minY" - Minimum Y-Level ore can spawn above
  • "maxY" - Maximum Y-Level ore can spawn below
  • "maxVeinSize" - Maximum size of ore vein
  • "spawnRate" - How many attempts at generating the ore per chunk
  • "biomeBlacklist" - List of forbidden biome names where the ore cannot generate [Choose either blacklist or whitelist or none of them]
  • "biomeWhitelist" - List of allowed biome names where the ore can generate [Prioritized above blacklist]
