I do use Corona, yes, but I’m seeing standard render (and standard C4D materials) – I don’t see what’s with the file on a quick examination, the light is a spot light not pointed at EVE so no shadow there, the Sun object is an infinte light and from the Help
“Since a Infinite light is infinite, the light has no actual origin. Thus the exact position of a Infinite light, near or far, has no effect on your scene’s objects. Only the actual direction in which the light is facing is important with this light source.”
and the direction of a light is always along the Z axis of the light (except Omni’s) and the Sun objects Z axis is pointed up into the sky so no shadows….
ok a bit deeper into the file, the only possible shadow is from the Physical Sky and it does show in the Enhanced OpenGL but the city in the sky has a Floor object, that’s the problem. It may look like a square in your scene but that’s just for convenience really it extends infinitely in all directions and it’s blocking your shadows. Turn it off.
