### Remarks

For example if a [GameObject](/engine/6000.7/script-reference/unityengine/gameobject.md)'s `layer` is set to 2, and the second bit of the camera's `cullingMask` is set to zero, the GameObject will be invisible to the camera. See [Layers](/engine/6000.7/manual/working-with-gameobjects/layers.md) for more information.
