eliminate edges that can appear on a surface under certain circumstances.
Default=50.
NOTE Soften Diffuse Edge slightly reduces the intensity of the light. You can
counter this, to some extent, by increasing the Multiplier value.
Diffuse When on, the light affects the diffuse properties of an object's surface.
When off, the light has no effect on the diffuse surface. Default=on.
Specular When on, the light affects the specular properties of an object's
surface. When off, the light has no effect on the specular properties.
Default=on.
For example, by using the Diffuse and Specular check boxes you can have one
light color the specular highlights of an object, while not coloring its diffuse
component, and then have a second light color the diffuse component of the
surface while not creating specular highlights.
