Is there a way to generate world terrain from a heightmap image dynamically through code? (basically, I'd like to have a simple world editor inside my game, so I need to be able to load in a heightmap)

There's a way to do this through EditorInterface but I don't think it works when the game is already running, since you need to connect to the editor. Also there's a way to make a mesh from a heightmap, but then it's not treated as a world, so there's probably no area streaming and such.

(on a sidenote, the search function on the forum is currently broken, here's the error it shows when you try to search: https://imgur.com/a/TT5aJ76)
