Ok, so I am making a map, and I have put a lot of work into it. But I need a biome mod that changes what the biome you are in is. I want to change a plains biome into a nether-like biome, for my nether-themed castle. I used to have a mod that could do that, but I haven't reinstalled it since the update, and I forgot its name. If you know any mods like that, could you please recommend it?
