The term "culling layer" pertains specifically to how a camera component determines which game objects are visible during rendering. By assigning game objects to specific culling layers, the camera can selectively include or exclude those objects from being rendered in the scene. This is particularly useful for optimization purposes and ensuring that only relevant objects are processed, which can enhance the performance of the game by reducing the number of objects the rendering engine needs to account for.

Using culling layers allows developers to have a higher degree of control over the visual aspects and performance of their games. For example, if certain objects are not meant to be seen by the player in a particular camera’s view (like behind-the-scenes elements or objects not relevant to the immediate gameplay), those can be placed on a separate culling layer. The camera can then be configured to ignore that layer, thus not rendering those objects at all.

While culling layers can indirectly influence aspects like rendering speed by allowing the system to skip rendering certain objects, they primarily define the visibility of objects to the camera. Therefore, this understanding of culling layers directly aligns with their function, which is to manage what is visible in the camera's perspective.
