Seeking a Blueprint Solution, I’ve come up with a few ideas that could be used along with the standard landscape (warning these will require flushing out):
- Generate a Terrain (Skeletal Mesh) in 3rd Party with Target Morphs arranged in a Grid.
- Generate a modular Tile sets with different Terrains shapes to swap out in-game.
I’m developing a suite of in-game editor applications that use the modular approach. I have other ideas, but, would require greater detail on what you’re aiming to accomplish.
