Shininess: A slider that sets how strong an object’s highlights appear. Higher values create
a glossier appearance. This Shininess parameter is disabled when the Highlights parameter
is deselected.
Disable lighting
Lighting effects can significantly impact playback performance. You can temporarily disable
lighting to improve playback speed while working on other aspects of your project.

Shadows
Shadows overview
Motion scenes that include Point or Spot lights can recreate more natural, realistic effects by
casting shadows. Shadows are created when an opaque or semi-opaque object blocks light from
hitting another object. To see a shadow in Motion, you need at least three things: A shadow-
casting light source, an object to cast a shadow, and another object upon which the shadow
is cast. Multiple lights cast multiple shadows that may or may not be visible depending on the
relative positions and settings of the objects in the scene.
Note: Ambient and Directional lights do not cast shadows.
WARNING: Some changes you make to 3D objects with shadows applied cause shadows to
disappear. This occurs when the change causes rasterization of the 3D object—adjusting the
opacity of a group or turning on the glow attributes for a text object, for example. Flattening
the 3D group allows it to cast shadows again. For more information about disappearing
shadows, see
Shadows and rasterization on page 1052.
In Motion, you can control whether a light source creates shadows and whether each object in
the scene receives shadows and/or casts shadows. You can even have an object cast a shadow
when it is invisible. The strength, sharpness, shape, and position of the shadow depends on the
type and positions of the lights and relative position of all three objects.
