Info:
Ore Tweaker is a super lightweight utility mod that allows you to customize and tweak the underground generation in Minecraft using JSON files. The mod can be both installed on a server or a client.
Tips:
I strongly recommend using World Stripper to debug and test your ore generation alongside this mod.
