I’m trying to figure out how to make a 1000km by 1000km flat map with a world partition and I can’t figure out the fastest way. The only way I know for now is LandscapeMode/Manage/Add but that would take a long time. I know I’m missing something because I haven’t worked in this part of the engine before
That’s pretty much the only choice you’ve got if you’re going for high resolution and large area. Make your initial landscape as large as you can with the memory you have available, load only a small section of it and then add. You can increase the brush size to more than just one component, but it’ll take a bit longer for it to process adding them on each click. If you’re okay with lower resolution (like 5m per heightmap pixel or more), you can just scale up the landscape on X and Y.
The only other thing you can do is make multiple landscape actors and overlap them, but you won’t be able to sculpt or paint where the landscapes overlap, so unless you’re importing heightmaps and layer weights or splat maps generated in another program it’ll be basically impossible to make it seamless (and even if you are importing those, there’ll be some shading artifacts on the overlap).
The OTHER other choice is to generate your desired landscape as static meshes in an external DCC and import them, but then you’ll have to keep going back and forth to the DCC to make changes to the landscape, and you won’t be able to use a Landscape material, or Landscape splines or really any of the other things that Landscape enables, so you’d ultimately be making more work for yourself down the line with that method.

Thank you for the information. Looks like I’ll stick with the way I’ve been. I have an additional question regarding setting up new LandscapeRegions such as these four already existing ones. Can I just copy/paste them?
Yeah, you can duplicate the auto-created ones, or you can drop in a new Location Volume from the actor placement panel and resize it however you want, or you can box select an area in the World Partition map and load it, and then right-click the loaded area and select ‘Convert Selected Regions to Actors’ to create a Location Volume.
