A mod to change the relative size of ore veins, and configure various generation patterns. It uses a block-tree system similar to Factorio modding's Lua prototypes to describe ores and their properties, as well as includes an inheritance system where unspecified properties are automatically inherited from the parent.
It automatically generates a folder in the config folder, and any files ending in .lua, .txt, .ini, .cfg, or .yml (all formatted like the above) will be read and parsed into ore prototypes. Much like with Minetweaker, they can be reloaded at will with the command /reloadoreconfig.
The mod contains a sample file in the jar ("example.lua") to show the general format and various parameters that can be customized.
