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

**Note:** This class is only compiled in editor builds. Run-time glTF loading and saving is *not* available in exported projects. References to **GLTFLight** within a script will cause an error in an exported project.

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

.. _class_GLTFLight_property_color:

.. rst-class:: classref-property

:ref:`Color<class_Color>` **color** = ``Color( 1, 1, 1, 1 )``

.. rst-class:: classref-property-setget

- void **set_color** **(** :ref:`Color<class_Color>` value **)**
- :ref:`Color<class_Color>` **get_color** **(** **)**

The :ref:`Color<class_Color>` of the light. Defaults to white. A black color causes the light to have no effect.

.. rst-class:: classref-item-separator

----

.. _class_GLTFLight_property_inner_cone_angle:

.. rst-class:: classref-property

:ref:`float<class_float>` **inner_cone_angle** = ``0.0``

.. rst-class:: classref-property-setget

- void **set_inner_cone_angle** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_inner_cone_angle** **(** **)**

The inner angle of the cone in a spotlight. Must be less than or equal to the outer cone angle.

Within this angle, the light is at full brightness. Between the inner and outer cone angles, there is a transition from full brightness to zero brightness. When creating a Godot :ref:`SpotLight<class_SpotLight>`, the ratio between the inner and outer cone angles is used to calculate the attenuation of the light.

.. rst-class:: classref-item-separator

----

.. _class_GLTFLight_property_intensity:

.. rst-class:: classref-property

:ref:`float<class_float>` **intensity** = ``1.0``

.. rst-class:: classref-property-setget

- void **set_intensity** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_intensity** **(** **)**

The intensity of the light. This is expressed in candelas (lumens per steradian) for point and spot lights, and lux (lumens per m²) for directional lights. When creating a Godot light, this value is converted to a unitless multiplier.

.. rst-class:: classref-item-separator

----

.. _class_GLTFLight_property_outer_cone_angle:

.. rst-class:: classref-property

:ref:`float<class_float>` **outer_cone_angle** = ``0.785398``

.. rst-class:: classref-property-setget

- void **set_outer_cone_angle** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_outer_cone_angle** **(** **)**

The outer angle of the cone in a spotlight. Must be greater than or equal to the inner angle.

At this angle, the light drops off to zero brightness. Between the inner and outer cone angles, there is a transition from full brightness to zero brightness. If this angle is a half turn, then the spotlight emits in all directions. When creating a Godot :ref:`SpotLight<class_SpotLight>`, the outer cone angle is used as the angle of the spotlight.

.. rst-class:: classref-item-separator

----

.. _class_GLTFLight_property_range:

.. rst-class:: classref-property

:ref:`float<class_float>` **range** = ``inf``

.. rst-class:: classref-property-setget

- void **set_range** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_range** **(** **)**

The range of the light, beyond which the light has no effect. GLTF lights with no range defined behave like physical lights (which have infinite range). When creating a Godot light, the range is clamped to 4096.

.. rst-class:: classref-item-separator

----

.. _class_GLTFLight_property_type:

.. rst-class:: classref-property

:ref:`String<class_String>` **type** = ``""``

.. rst-class:: classref-property-setget

- void **set_type** **(** :ref:`String<class_String>` value **)**
- :ref:`String<class_String>` **get_type** **(** **)**

The type of the light. The values accepted by Godot are "point", "spot", and "directional", which correspond to Godot's :ref:`OmniLight<class_OmniLight>`, :ref:`SpotLight<class_SpotLight>`, and :ref:`DirectionalLight<class_DirectionalLight>` respectively.
