Remember a few years back when Sethbling made that cool skygrid map? This is the same idea as a world generation option. Why is this better you may ask? It isn't. Sethbling is a beast and cannot be topped. Seriously though, this mod automatically adds world gen from some other mods if those mods are loaded.
The mods integrated into world gen so far are:
Applied Energistics 2
Is your favorite mod not on that list? If it doesn't add any world gen, don't worry about it, I didn't mess with anything other than world gen and they should work just fine. If they only add new ores that everyone uses like copper and tin, they should work just fine as well. If their world gen only happens their own dimension, such as the aether or twilight forest, they will also work fine, but that dimension won't be in skygrid style. If they did add other types of world gen to vanilla dimensions, such as thaumcraft (Now supported!) or IC2, you will be missing vital parts of the mod. Sorry about that.
The license for this mod is zlib/libpng, meaning do whatever you want with it as long as you don't take credit for the mod itself.
