Recently I've been interested in creating a mod pack, and my idea for the mod pack includes the need for an all-dirt world with no other block generation what-so-ever except for a layer of bedrock on the bottom. If all else fails I can do a super flat with 64 layers of dirt but I'd really like to use some terrain. I've looked at COFH World and Open Terrain Generator but I'm not sure if I can use either of these to do my world gen. I want absolutely no ores, no foliage, no modded structures, and no water/lava pools with a single biome, preferably plains. Is there a good way to make a world like this? I only need the world once, since I plan on using perfect spawn point mod and hardcore world reset to use the same save over and over. Any help would be appreciated, whether a mod can do this or just a save. Thanks!
