VisualInstance3D
================

**Inherits:** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

**Inherited By:** :ref:`Decal<class_Decal>`, :ref:`FogVolume<class_FogVolume>`, :ref:`GPUParticlesAttractor3D<class_GPUParticlesAttractor3D>`, :ref:`GPUParticlesCollision3D<class_GPUParticlesCollision3D>`, :ref:`GeometryInstance3D<class_GeometryInstance3D>`, :ref:`Light3D<class_Light3D>`, :ref:`LightmapGI<class_LightmapGI>`, :ref:`ReflectionProbe<class_ReflectionProbe>`, :ref:`RootMotionView<class_RootMotionView>`, :ref:`VisibleOnScreenNotifier3D<class_VisibleOnScreenNotifier3D>`, :ref:`VoxelGI<class_VoxelGI>`

Parent of all visual 3D nodes.

Description
-----------

The ``VisualInstance3D`` is used to connect a resource to a visual representation. All visual 3D nodes inherit from the ``VisualInstance3D``. In general, you should not access the ``VisualInstance3D`` properties directly as they are accessed and managed by the nodes that inherit from ``VisualInstance3D``. ``VisualInstance3D`` is the node representation of the :ref:`RenderingServer<class_RenderingServer>` instance.

Property Descriptions
---------------------

.. _class_VisualInstance3D_property_layers:

- :ref:`int<class_int>` **layers**

+-----------+-----------------------+
| *Default* | ``1``                 |
+-----------+-----------------------+
| *Setter*  | set_layer_mask(value) |
+-----------+-----------------------+
| *Getter*  | get_layer_mask()      |
+-----------+-----------------------+

The render layer(s) this ``VisualInstance3D`` is drawn on.

This object will only be visible for :ref:`Camera3D<class_Camera3D>`\ s whose cull mask includes the render object this ``VisualInstance3D`` is set to.

Method Descriptions
-------------------

.. _class_VisualInstance3D_method__get_aabb:

- :ref:`AABB<class_AABB>` **_get_aabb** **(** **)** |virtual| |const|

----

.. _class_VisualInstance3D_method_get_aabb:

- :ref:`AABB<class_AABB>` **get_aabb** **(** **)** |const|

Returns the :ref:`AABB<class_AABB>` (also known as the bounding box) for this ``VisualInstance3D``. See also :ref:`get_transformed_aabb<class_VisualInstance3D_method_get_transformed_aabb>`.

----

.. _class_VisualInstance3D_method_get_base:

- :ref:`RID<class_RID>` **get_base** **(** **)** |const|

Returns the RID of the resource associated with this ``VisualInstance3D``. For example, if the Node is a :ref:`MeshInstance3D<class_MeshInstance3D>`, this will return the RID of the associated :ref:`Mesh<class_Mesh>`.

----

.. _class_VisualInstance3D_method_get_instance:

- :ref:`RID<class_RID>` **get_instance** **(** **)** |const|

Returns the RID of this instance. This RID is the same as the RID returned by :ref:`RenderingServer.instance_create<class_RenderingServer_method_instance_create>`. This RID is needed if you want to call :ref:`RenderingServer<class_RenderingServer>` functions directly on this ``VisualInstance3D``.

----

.. _class_VisualInstance3D_method_get_layer_mask_value:

- :ref:`bool<class_bool>` **get_layer_mask_value** **(** :ref:`int<class_int>` layer_number **)** |const|

Returns whether or not the specified layer of the :ref:`layers<class_VisualInstance3D_property_layers>` is enabled, given a ``layer_number`` between 1 and 20.

----

.. _class_VisualInstance3D_method_get_transformed_aabb:

- :ref:`AABB<class_AABB>` **get_transformed_aabb** **(** **)** |const|

Returns the transformed :ref:`AABB<class_AABB>` (also known as the bounding box) for this ``VisualInstance3D``.

Transformed in this case means the :ref:`AABB<class_AABB>` plus the position, rotation, and scale of the :ref:`Node3D<class_Node3D>`'s :ref:`Transform3D<class_Transform3D>`. See also :ref:`get_aabb<class_VisualInstance3D_method_get_aabb>`.

----

.. _class_VisualInstance3D_method_set_base:

- void **set_base** **(** :ref:`RID<class_RID>` base **)**

Sets the resource that is instantiated by this ``VisualInstance3D``, which changes how the engine handles the ``VisualInstance3D`` under the hood. Equivalent to :ref:`RenderingServer.instance_set_base<class_RenderingServer_method_instance_set_base>`.

----

.. _class_VisualInstance3D_method_set_layer_mask_value:

- void **set_layer_mask_value** **(** :ref:`int<class_int>` layer_number, :ref:`bool<class_bool>` value **)**

Based on ``value``, enables or disables the specified layer in the :ref:`layers<class_VisualInstance3D_property_layers>`, given a ``layer_number`` between 1 and 20.
