I have highlighted the worst areas in the scene with a red circle and the blue arrow shows that Static: Unless you’re very performance constrained you probably don’t want a static directional light, because they won’t cast dynamic shadows (though I think capsule shadows will work) Stationary: Ideal in situations where the sun doesn’t need to move, because they provide both baked indirect lighting and dynamic shadows. Their type and The cause seems to be enabling Dynamic Shadows on the Directional Light, and the problem is most easily seen on landscape or terrain with some slopes on it.
