Enumerations

.. _enum_GeometryInstance_ShadowCastingSetting:

.. _class_GeometryInstance_constant_SHADOW_CASTING_SETTING_OFF:

.. _class_GeometryInstance_constant_SHADOW_CASTING_SETTING_ON:

.. _class_GeometryInstance_constant_SHADOW_CASTING_SETTING_DOUBLE_SIDED:

.. _class_GeometryInstance_constant_SHADOW_CASTING_SETTING_SHADOWS_ONLY:

enum **ShadowCastingSetting**:

- **SHADOW_CASTING_SETTING_OFF** = **0** --- Will not cast any shadows.

- **SHADOW_CASTING_SETTING_ON** = **1** --- Will cast shadows from all visible faces in the GeometryInstance.

Will take culling into account, so faces not being rendered will not be taken into account when shadow casting.

- **SHADOW_CASTING_SETTING_DOUBLE_SIDED** = **2** --- Will cast shadows from all visible faces in the GeometryInstance.

Will not take culling into account, so all faces will be taken into account when shadow casting.

- **SHADOW_CASTING_SETTING_SHADOWS_ONLY** = **3** --- Will only show the shadows casted from this object.

In other words, the actual mesh will not be visible, only the shadows casted from the mesh will be.

----

.. _enum_GeometryInstance_Flags:

.. _class_GeometryInstance_constant_FLAG_USE_BAKED_LIGHT:

.. _class_GeometryInstance_constant_FLAG_MAX:

enum **Flags**:

- **FLAG_USE_BAKED_LIGHT** = **0** --- Will allow the GeometryInstance to be used when baking lights using a :ref:`GIProbe<class_GIProbe>` or :ref:`BakedLightmap<class_BakedLightmap>`.

- **FLAG_MAX** = **2** --- Represents the size of the :ref:`Flags<enum_GeometryInstance_Flags>` enum.

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

Base node for geometry based visual instances. Shares some common functionality like visibility and custom materials.
