Strange "shadows" with Unity 5

Hello everyone,

I’m trying to make a mobile game for Android with Shadows.
But something looks strange with them:

So what can I do?

What exactly are you referring to? The dark squares on the street and sidewalk? This looks like it was baked onto the texture via lightmapping. But just a shot in the dark. Try clearing all lightmapping data and if that wasn’t the problem, maybe do more testing and elaborate on what is happening where exactly.
