This is the successor of NotEnoughResources.

Bleeding edge builds are the ones tagged as alpha

 Features:

• Mob Drops

  
  
  

• Dungeon Loot

  
  
  

• Ore Gen

  
  
  

• Plant Drops

  

• DIY ore graphs

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. It also requires a game restart to start using newly profiled data.
