Object Lighting Parameters
All lightable objects have properties that control how they react to lights in a scene. You
can adjust these properties for an object via the Lighting section of the Properties
Inspector.
Shading:
A pop-up menu that enables you to set how an object responds to lights in
the scene. If set to On, the object can be lit. If set to Off, the object ignores scene lights.
If set to Inherited (the default), the object uses the Shading value of its parent.
Note: It is possible to set the Shading parameter of a child of a group (however deep it
is nested) to On. That setting overrides any group settings previously applied to the child
object.
Highlights:
A checkbox that controls whether lit objects show highlights. This parameter
has no effect if Shading is set to Off.
Shininess:
A slider that sets how strong an object’s highlights appear. Higher values
create a glossier appearance. If the Shininess slider is not visible, click the disclosure
triangle next to Highlights to reveal it. This Shininess parameter is disabled when the
Highlights parameter is deselected.
You might need to fine-tune object surface properties and lighting parameters to achieve
a specific result.
