Which statement accurately describes the function of a Culling Mask in Unity cameras?

A Culling Mask in Unity cameras is a fundamental feature that defines which layers in a scene are visible to the camera. When you assign layers to a camera’s Culling Mask, you effectively filter out what the camera should render. This means that any GameObject assigned to a layer not included in the Culling Mask will not be drawn or rendered by that camera, allowing for efficient scene management and optimization.

For instance, if you have multiple layers for different elements in your game, such as a user interface, background objects, or certain characters, the Culling Mask can be adjusted to show only the desired layers. This functionality is particularly useful in complex scenes to reduce rendering overhead and to manage visibility effectively based on various gameplay contexts.

The other options address concepts that do not relate to the specific functionality of the Culling Mask. Controlling animation speed pertains to the Animator component, setting audio output layers relates to audio settings and sounds, while defining lighting settings involves global illumination and specific light configurations in the scene.
