Apologies if this has already been addressed, it seems like it would be a major issue if the only fix is to build or place meshes behind these rock walls.
Lighting with Lumen
2-Sided for Backface culling is not an optimal fix, and the low res base mesh shows in black pathes.
Even after placing blocking geo behind the rock façade, it doesn’t self shadow, so you can see the light on the edges of the wall beyond the 90 degree edge.
Path-tracing fixes the issue but isn’t the way to work.
Hardware Raytracing exhibits the same issue.

What could I be missing here?
