Models do not receive any shadow, they can cast a shadow but not receive it, this makes things look unnatural and unrealistic when you have a house the interior receive only lighting and no shadows, this will be fixed by adding shadow receiving support for models as the terrain already have this feature and the shadows on the terrain looks pretty good and realistic and it uses a variation of ray tracing to calculate shadows.
