The following three parameter groups in the Properties Inspector—Lighting, Shadows,
and Reflection—appear only when the parent group is set to 3D.
Lighting Parameters
Shading: A pop-up menu that sets how a layer responds to lights in the scene. There are
three options:
• Inherited: The layer uses the shading value of its parent.
• On: The layer can be lit.
• Off: The layer ignores scene lights.
Highlights: When this checkbox is selected, lit layers in the scene show highlights. This
parameter has no effect if Shading is set to Off. Click the disclosure triangle to reveal an
additional Shininess parameter.
• Shininess: A slider that sets how strong a layer’s highlights appear. Higher values create
a glossier appearance.
For more information on using lights, see Lighting.
Shadows Parameters
Cast Shadows: A checkbox that sets whether a shadow is cast when a layer lies between
a light source and another layer.
Note: This parameter does not affect drop shadows.
Receive Shadows: Controls whether neighboring layers’ shadows affect the current layer.
When this checkbox is deselected, light affects the layer as if the shadow-casting layer
did not exist.
Shadows Only: A checkbox that, when selected, specifies that a layer blocks light and
casts a shadow, while the layer itself does not appear in the scene.
Note: For more information on using shadows, see Shadows.
Reflection Parameters
Reflectivity: A slider that controls the shininess of the layer’s surface. When set to 0%,
there is no reflectivity. When set to 100%, the layer is totally reflective, like a mirror.
Blur Amount: A slider that controls how blurry the reflection appears, creating the
appearance of soft focus due to the surface quality of the reflecting layer.
Falloff: A checkbox that controls whether the reflection fades with distance from the
layer, producing a more realistic result. Click the disclosure triangle to show additional
controls that adjust the falloff effect: Begin Distance, End Distance, and Exponent. The
Exponent slider adjusts how quickly the reflection becomes fainter as reflected layers
move away from the reflecting layer.
Blend Mode: A pop-up menu that determines the blend mode used for the reflection.
Note: For more information on using reflections and their parameters, see Reflections.
