Generate ores in your world for future use by other mods. Control how they generate, even regenerate ores in your existing world.
The ores this mod adds don't actually do anything on their own. You need other mods to utilize the ores.
This is an Beta release. I am not responsible for lost or corrupt worlds. Be sure to back up any existing worlds before running. Especially if regenerating ores.
