Along with this setting, we have two more settings to control the way the reflection
in a material behaves. If we pick the
Reflection Colorize
setting and start to move
the slider from one extreme to another, it is easy to understand why the word
"colorize" is used to describe the setting. Here, we can control how the material will
reflect the environment and the sources of light present in our scene.
And we can go even further on tweaking the reflection by turning our attention to
the
Reflection Falloff
setting. We could also use the word Fresnel to describe what
this setting does to the reflection.
Fresnel
Fresnel
is the amount of reflection visible on a surface, which depends on the
viewing angle. It may be difficult to see this effect on the following screenshot:
However, try to place the camera at the same angle and start increasing the
Reflection Falloff
setting, and when we look at the surface or when the surface is
close to the camera, we will not see much reflected light. When we have the camera
angle similar to the one shown in the preceding screenshot, we see many more
reflections on the surface. However, we still have a few more settings that need to be
covered. The
Brightness
setting is self-explanatory—a high value creates an extreme
bright material and a low value an extreme dark material. However, what about the
Glossiness
setting?
