# Modifying Surface Lighting

After you set the parent-to-child relationships between lights and surfaces, you can set specific surface lighting properties. You control a surface's lighting and adjust the surface's specular highlight in the Surface menu. To access the Surface menu, double-click the selected surface in the schematic, or follow the tab population rules for the Object menu (see Populating Menu Tabs of Selected Objects).

The Surface controls that relate to lights are described as follows.

Motion Blur button
  Enable to exclude the selected object from the global motion blur effect. See Blurring a Single Object.
Wireframe button
  You can remove some lighting effects for a selected surface by converting surfaces to a wireframe depiction of the surface. See Converting to Wireframe.
Flip Normals button
  Flips the normals of the surface so that light is applied to the opposite side of the surface. See Flipping a Surface's Normals.
Shine field
  Displays the intensity of the specular highlight. See Adjusting Specular Highlights.
Lighting box
  Applies diffuse or ambient lighting to a surface. See Applying Incidental Light Reflection.
Specular Highlight colour box
  Click the colour pot and use the colour picker to change the specular colour.

The specular highlight is visible only if Shading is enabled and Shine is greater than 0. See Adjusting Specular Highlights.
