MMD OreSpawn Library FAQ
6 questions players actually ask, answered.
What is MMD OreSpawn Library?
It is a library mod that gives you better control over how ores spawn in Minecraft. It works by parsing .json files in the orespawn folder and adding ore generators based on them.
Where does the mod look for its configuration files?
It parses all of the .json files found in the orespawn folder. Each file defines ore generators that get added to the game.
How do I control which dimension an ore spawns in?
Set the "dimension" field in the JSON entry, such as -1 for the Nether. Entries without a dimension field apply to the overworld.
What does the "block" field do in an ore entry?
It specifies the block to generate, using a namespaced ID like "minecraft:quartz_ore". The mod then spawns that block as an ore.
What do min_height and max_height control?
They set the vertical range in which the ore can generate. For example, diamond ore with min_height 0 and max_height 16 only spawns near the bottom of the world.
What is the difference between "size", "variation", and "frequency"?
"size" sets the number of blocks in an ore vein, "variation" adds randomness to that size, and "frequency" controls how often veins are attempted per chunk. Higher frequency means more veins.
