Opacity: This slider controls the apparent opacity of the shadow. Dragging the slider to the left
creates a lighter shadow.
Opacity set to 75%
Opacity set to 25%
•
Softness: This slider determines how blurry a shadow will appear.
Note: The appearance of a shadow depends on the rendering quality of the object casting it.
Because a shadow may be larger than the original object, you may see some jagged edges or
aliasing on the shadow. If you see such artifacts, check how your image looks when the project
is set to best quality, rather than draft or normal. For more about Canvas display quality, see
on page 57.
•
Uniform Softness: This checkbox lets you constrain the results of the softness slider to a
uniform amount of blur on the shadow regardless of distance between the light, the object
casting the shadow, and the object receiving the shadow.
By deselecting the checkbox, you enable nonuniform softness, where the farther the objects
are from each other, the more blur is applied.
Note: Selecting nonuniform softness can impact playback performance.
