So I have this modpack I made for myself and at first I was unhappy with how the mobs in the over world were spawning, so I got CMS and that has really done the trick. However, it has opened up a new problem: Most of my modded dimensions are all messed up. For example: the Aether is completely empty with no mobs. I really only need Custom Mob Spawner to work in the overworld. I have a feeling i could configure each and every entity, biome, and dimension in the config files, but that could take days. So before I think about that (or just outright removing CMS), I was wondering if anyone knew if it was possible to make it so Custom mob spawner works only in the over world, and allow for vanilla mob spawning to take over in the other dimensions.
