One more tiny little tip to add to the rest of these good ideas. If you have a light that is a lamp post, or something like it, place at least two point lights inside the light fixture, and offset the point lights a little bit. This will cause your shadows on the nearby buildings or the ground to be significantly softer. (In theory, the softness setting for the lights does this, but mostly, in Vue, it just creates a scatter effect of tiny littlg dark and light grains on the buildings or nearest objects. I didn't like this, so I just thought about what I'd learned of light behavior in high school physics.)
