Is there a trick to get rid of the light leaking with one sided meshes?
I can get it to cast shadows with “cast shadows as two sided”, or change the material to two sided, but the light artifacts are still present.
- The mesh seems to self-shadow as if it was in the light at certain angles.
- The light leaks at the bottom where the mesh intersects with the landscape.

A workaround is the make the mesh whole, but that takes a lot of time.
