Lighting options

Light 
Defines where the light is. Drag the light to where you want it on the sphere.

Move Light Back button 
Moves the selected light behind the object.

Move Light Front button 
Moves the selected light in front of the object.

New button 
Adds a light. By default, new lights appear in the front center of the sphere.

Delete Light button
Deletes the selected light.
Note: By default, 3D Effects assigns one light to an object. You can add and delete lights, but the object must always have at least one light.

Light Intensity
Changes the selected light’s intensity between 0% and 100%.

Shading Color
Controls the object’s shading color, depending on the command you choose:
None
Adds no color to the shading.

Custom
Lets you choose a custom color. If you choose this option, click the Shade Color box to select a color in the Color Picker. Spot colors are changed to process colors.

Black Overprint
Avoids process colors if you’re using a spot color workflow. The object is shaded by overprinting shades of black on top of the object’s fill color. To view the shading, choose View > Overprint Preview.

Preserve Spot Color
Lets you preserve spot colors in the object. Spot colors can’t be preserved if you chose Custom for the Shading Color option.
