Alternate Terrain Generation Mod for MCPE

Alternate Terrain Generation Mod (ATG) is a complete replacement for the vanilla overworld terrain generator which radically changes the way the world looks, and the way in which you will play.

Rather than picking a biome for a region and then building the terrain for that biome, ATG generates a series of fields for height, temperature, rainfall and more, in order to derive the final biome from these. The result is a smoother variation in the terrain, and biomes which would realistically be found adjacent to one another.
