hmm

Netherending Ores fügt nur die OreBlöcke hinzu, benötigt aber selbst noch eine world-generation mod wie zB. COFH World oder MMD OreSpawn.

Ore Generation
Other mods such as CoFH World will be needed to control the ore spawning. Sample configs are provided for CoFH World, check here. Extract the ore generation configs from the provided zip file to config\cofh\world\ of your modpack instance in order to use them. Nether ore generation is based off config settings from the last release of the Nether Ores mod by skyboy026/powercrystals for MC 1.7.10. There are some minor changes, including adding ores that never existed in that mod. The End uses similar settings to the Nether but reduced size/count as the height range of naturally generated End Stone is far less.
