It would be nice to see the island from a distance as in a rope bridge to a much smaller static mesh floating island, or a waterfall dropping off the edge of the end and possible platforming around the side of it. It’s a shame you can’t shape/delete the landscape in a circle sort of shape. I might use your idea but mask the edges with a few static meshes to simulate the look of a floating island. As far as I can see that might be the best way unless anyone knows anything different.
Thanks for responding
