The sole purpose of these options is to animate the corresponding object’s role in the scene. Even if several background objects are present in the scene, Cinema 4D will only calculate the first background object listed in the Object Manager when the scene is rendered. By activating different background objects at different times their effect within the scene can be animated. The same applies to all objects listed above.
