  13. Description
  14. -----------
  15. **Camera3D** is a special node that displays what is visible from its current location. Cameras register themselves in the nearest :ref:`Viewport<class_Viewport>` node (when ascending the tree). Only one camera can be active per viewport. If no viewport is available ascending the tree, the camera will register in the global viewport. In other words, a camera just provides 3D display capabilities to a :ref:`Viewport<class_Viewport>`, and, without one, a scene registered in that :ref:`Viewport<class_Viewport>` (or higher viewports) can't be displayed.

  165. - :ref:`int<class_int>` **get_cull_mask** **(** **)**
  166. The culling mask that describes which :ref:`VisualInstance3D.layers<class_VisualInstance3D_property_layers>` are rendered by this camera. By default, all 20 user-visible layers are rendered.
  167. \ **Note:** Since the :ref:`cull_mask<class_Camera3D_property_cull_mask>` allows for 32 layers to be stored in total, there are an additional 12 layers that are only used internally by the engine and aren't exposed in the editor. Setting :ref:`cull_mask<class_Camera3D_property_cull_mask>` using a script allows you to toggle those reserved layers, which can be useful for editor plugins.
  168. To adjust :ref:`cull_mask<class_Camera3D_property_cull_mask>` more easily using a script, use :ref:`get_cull_mask_value<class_Camera3D_method_get_cull_mask_value>` and :ref:`set_cull_mask_value<class_Camera3D_method_set_cull_mask_value>`.
  169. \ **Note:** :ref:`VoxelGI<class_VoxelGI>`, SDFGI and :ref:`LightmapGI<class_LightmapGI>` will always take all layers into account to determine what contributes to global illumination. If this is an issue, set :ref:`GeometryInstance3D.gi_mode<class_GeometryInstance3D_property_gi_mode>` to :ref:`GeometryInstance3D.GI_MODE_DISABLED<class_GeometryInstance3D_constant_GI_MODE_DISABLED>` for meshes and :ref:`Light3D.light_bake_mode<class_Light3D_property_light_bake_mode>` to :ref:`Light3D.BAKE_DISABLED<class_Light3D_constant_BAKE_DISABLED>` for lights to exclude them from global illumination.

  178. If ``true``, the ancestor :ref:`Viewport<class_Viewport>` is currently using this camera.
  179. If multiple cameras are in the scene, one will always be made current. For example, if two **Camera3D** nodes are present in the scene and only one is current, setting one camera's :ref:`current<class_Camera3D_property_current>` to ``false`` will cause the other camera to be made current.
