•
Blur Amount: This slider controls whether real reflections appear in sharp focus or quite blurry,
depending on the surface quality of the reflecting object.
•
Falloff: This checkbox determines whether the reflection fades with distance from the object,
producing a more realistic result.
No Falloff
With Falloff
When the Falloff checkbox is selected, additional controls become available. Click the
disclosure triangle beside the Falloff checkbox to reveal these controls:
•
Begin Distance: This slider determines the distance (inside the reflection) where the falloff
begins. When the slider is set to 0, falloff starts at the reflection plane.
•
End Distance: This slider determines the distance where the falloff ends, beyond which the
reflection isn’t visible. Adjusting this slider moves the falloff point closer to the reflection
plane, which causes less of the reflected image to appear.
•
Exponent: This slider controls how quickly a reflection gets fainter as the reflected object
gets farther from the reflective surface.
•
Blend Mode: This pop-up menu determines the blend mode used for the reflection. Blend
modes other than “add” are useful for achieving different looks, even if they aren’t physically
intuitive. For more about blend modes, see
on page 229.
Other reflection parameters
•
Casts Reflection: The Properties Inspector of every object also contains a Casts Reflection
pop-up menu (in the Blending section) that controls whether an object is reflective. There are
three options:
•
Yes: The object is reflected in nearby reflective objects.
