Falloff: This checkbox determines whether the reflection fades with distance from the
object, producing a more realistic result. There are additional options in the Falloff section
when this checkbox is enabled:
No Falloff
With Falloff
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 Blend Modes.
