This mod allows the player to decide what ores are generated in their worlds and how they are distributed. In addition to the vanilla “cluster” distribution, it currently offers custom-written “vein” and “cloud” distributions.

CustomOreGen supports mod-added ores, biomes, and dimensions. The default config file includes RedPower ores and ExtraBiomesXL biomes out of the box, and config data for other mods is easily added.
