As I said before, we need some lights to simulate the diffuse light coming from the atmosphere or as a reflection from the different surfaces. Without the usage of GI, we have to do it this way.
Moon Bouncing Lights
As the name suggests, these lights should simulate the indirect light coming from the sky (yes, even at night). Both bouncers are identical in their parameters apart from their position, strength and some variation in color (Fig.27).
Let's get some extra definition onto the facades (Fig.28).
When you study the parameters of all light sources, you will discover that light coming from above has a cool color tone. Light coming from lamps, windows or reflections are generally warmer in hue. Bouncer 4 helps to get more light onto the small structures of the buildings (Fig.29).
