Downloaded Caprica and have already added the snake temple to the monument map. Caprica being younger than Ragnar does not have as much in the world as Ragnar that it feels right to add. That said I will definitely be porting in the steampunk mecha, Neo-Castle Gasbandia, Shroomshire, and Dirona's tower.
It will be awhile before the monument map is "finished" each area I import has to be first cropped out of it's world map, be imported in to a blank world, have all bedrock removed, then be "sculpted" in to a flying "island" (made easier by the Explosives+ mod). As I do this more my technique improves and I can import and slut faster. For example, old Gasbandia took about four hours of work to get imported and I am still not 100% happy with it. The Snake Temple, however, took about and hour, most of that spent trying to keep my cat from sleeping on my keyboard.
if anyone is interested in my criteria for what I import it is roughly this:
The area/structures imported must be aesthetically pleasing and moderately complex in design.
It must be a "complete" or "complete looking" construction.
It must fit the aesthetic of the map I am building (a quasi-medieval/steampunk skyworld)
It must have a significant portion of it above ground (this is non-negotiable, see below)
I am making some edits so that things fit/transition more smoothly. The most obvious edit being after importing the chunks I am carving them in to be floating islands/continents. I am also removing any pixel art. For example, when I imported the Playa the Nyan cats were toasted. Due to the import process I can not respect the sanctity of underground structures. A good example of this being in the Playa, Dwarftown was destroyed.
Some creative edits may also take place. This is being kept absolutely minimal though, the Playa is the most heavily edited thing I have imported to date. I honestly plan to keep it that way. The big edits are removal of all pixel art/sky letters, separating the lighthouse in to a separate chunk, removing unfinished projects, and all the water and lava being removed.
A good way to summarize the effect I am going for with what I import is Draenor from Burning Crusade in WoW. A fragmented world kinda floating in the ether.
