How do i change how high the ores spawn like diamonds and redstone, to me it's just too easy to get the diamonds when you can see them in a small cave the second i spawn I prefer having to risk my life getting them so i feel like i earned them I just wanna know how to revert it back to normal EDIT: if there is any special reason the ores spawn like that could someone please explain it to me? I dont even really know what all the mods do in hexxit, i just find things see what they do and use them :P
