Terrain Control is an advanced world generator. Through various configuration files it gives the user control over almost every aspect of Minecraft terrain generation, with no knowledge of Java required. It can be used on Bukkit or Forge servers and on singleplayer with Forge. Terrain Control is the successor to the old PhoenixTerrainMod, which was based on the popular BiomeTerrainMod. Terrain Control is maintained by Khoorn (known as Wickth on GitHub).
