Not in the new version... I haven't made any large terrain changes there yet. Considering it will be ocean & islands it will probably already have a lot of what I'm trying to accomplish with the java version.
In the java version, I've converted many biomes to Water World types, with extensive islands populated with critters & bandits. I'm currently converting an entire ocean biome into a large broken island ring similar to what you would see in the Marshall Islands, along with smaller islands in the middle (some with structures under them). Long rivers & canals (some underground), mostly bounded by thick vegetation, connect to other widely spaced areas, some taking quite a while to traverse. And then there are the constructions... I don't know if this amounts to 'large scale', but it sure is fun and habit forming.
Thank you again for such an awesome creation!
