Add Alien Biomes to Existing Save
I have a fairly nice base and have been enjoying this mod to its fullest.
The only part of the original setup I regret is not installing Alien Biomes.
As my base grew, it became a little too monotonous. And although the clarity of each section was nice, I would like to have some interesting visuals.
Therefore, how can I add Alien Biomes 9or similar) to an existing save. I tried just adding it and going to unexplored chunks, but none of the 'new' biomes were present. Searching online. There were forum posts about the mod "Regenerate Terrain", and while this "resets" the terrain, it still has no new biomes.
Is there any way to have some nice background visuals while keeping the current safe / resources?
(Pictured is my base, using Mapshot, versus my seed with alien biomes, which looks cooler, I think)
Addendum: I tried with changing the map gen in the editor, and this resulted in empty space at most spots (which is weird without space age, but sure), but no new biomes.)
An alternative is just moving the full base to a new save. But then, I assume, no items or time data will be transferred...
Thanks in advance!
