2.4.7.6 Shadowless Lights

Using the shadowless keyword you can stop a light source from casting shadows. These lights are sometimes called "fill lights". They are another way to simulate ambient light however shadowless lights have a definite source. The syntax is:

SHADOWLESS_LIGHT_SOURCE:
    light_source
    {
        <Location>, COLOR shadowless
        [LIGHT_MODIFIERS...]
    }
LIGHT_MODIFIER:
    AREA_LIGHT_ITEMS | GENERAL_LIGHT_MODIFIERS

shadowless may be used with all types of light sources. The only restriction is that shadowless should be before or after all spotlight or cylinder option keywords. Do not mix or you get the message "Keyword 'the one following shadowless' cannot be used with standard light source". Also note that shadowless lights will not cause highlights on the illuminated objects.
