Using the Future Mod "Solar System" map script I was able to substitute in our terrains with theirs and generate 5 different maps in one map. Note this is not multi-maps. Included are Earth, Luna, Mars, Venus, and Europa. Note they do not have all the types of terrains possible. This is also the first time I edited a map script so I am bound to get something wrong. If anyone wants to help make this map better, such as allowing for all types of terrains for Earth, Luna and Mars please make it happen. Like all map script they go in the mod's Private Maps folder. Hopefully this can help us test out other terrains before multi-maps come out. Enjoy!
