Shadow-Receiving Styles

A model's shadow-receiving style determines whether or not objects in a model receive shadows cast by other objects in the model. The shadow-receiving style is defined by a Boolean value. If a renderer's shadow-receiving style is set to kQ3True , objects in the scene receive shadows. If a renderer's shadow-receiving style is set to kQ3False , objects in the scene do not receive shadows.
