Shadows not working correctly

Hey I’m just having some difficulties with shadows

I have a building, however no sunlight comes through the windows, which means no shadows in the building from the sun.

Here are some screenshots:


Sun

No Light+ Shadows

any ideas?

Ik it sounds stupid, but try ensuring the windows have castshadow off? If that doesnt work try switching between Future and Shadowmap (Realistic and Non-Realistic for new lighting system). Additionally, yoh could try changing the rendering quality on any meshes in the wj dow from automatic/performance to precise.

Another thing i just noticed, your sun is almost exactly horizontal. This might make the sunrays cast on the walls behind you, try messing with time of day.
