I found a very weird issue when playing in a standalone game, is that there is a very weird patch of the black shadow that appears on the side of the dune. Initially, I thought that it was something to do with CSM or DFS, however even after disabling them the issue still remains. Force no precomputed lighting is on as well, so it can’t be static lightmaps. The issue disappears when I get close to it. It is not visible in the editor view.
