About this Mod
Lost Worlds is a companion mod for Lost Cities. It adds a new world preset that you can select during world creation and allows for five different types of worlds:
- Islands: this is a void world with floating islands. In combination with Lost Cities you can populate these islands with cities (use the 'floating' profile for that)
- Caves: this is a world similar to the nether but with regular stone and ores. You can use this in combination with the 'cavern' profile for Lost Cities. Warning! This is very hard. It may be recommended to use a spawn chest to help get started
- Spheres: this is a void world that you can use in combination with the 'space' profile for Lost Cities. This will generate spheres which may contain cities
- Normal: this is a normal style world that can be used in combination with the Lost Cities 'biosphere' profile. This is best used in combination with the 'Wastes' version of the world preset
- Atlantis: this is a normal style world that can be used in combination with the Lost Cities 'atlantis' profile. The sea will be at height 90
