Shadows & Reflections list:
Select or deselect entries to enable or disable a shadow or
reflection. To select a shadow or reflection so that the controls on the right are active, click
anywhere on that row. The active shadow or reflection is highlighted in blue. You should not
load the reflection settings for a shadow, or vice versa.

Increasing this setting causes the shadow or reflection to fade starting at the far end.
