Just Enough Resources Mod (or JER) adds Just Enough Items (JEI) integration for world resources like ores and mob drops. By adding world-gen.json to the JER config folder and toggling the DIY setting ingame you can make your own ore distributions. You can even use /profile [chunk amount] [all] to create a world-gen-scan.json that will get the distributions from a generated world so you don’t have to guess. These features are quite advanced and only recommend for pack makers or experienced players. This mod is the successor of NotEnoughResources.
Features:
- Mob Drops.
- Dungeon Loot.
- Ore Gen.
