TIP To remove the inclusion or exclusion link, while still in Light Link mode, click and drag over the line that
connects the light source to the axis or image.
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 (page 459)).
The Surface settings that relate to lights are described as follows.
Specular Highlights
A specular highlight is a reflection of a light source. The position of the specular highlight depends on the
position and number of light sources surrounding a surface and the angle of the camera.
Use the Shine field to change the intensity of the specular highlight. When the Shine value is set to 0, the
specular highlight is disabled. To change the size of the specular highlight, use the Falloff field in the Light
menu.
This surface is lit using a Falloff of 20 and a Spread of 27.
The surface's Shine is set to 1.
This surface is lit using a Falloff of 30 and a Spread of 27.
The surface's Shine is set to 10.
By default, the specular highlight is the same colour as the light source. You can change the colour of the
specular highlight by changing the specular colour values.
The specular colour is the colour of light that is reflected by the surface. For example, if the specular colour
is red and the light source is white, the specular highlight is red. If the specular colour is yellow and the
light source is red, the highlight is orange.
