Enumerations
------------

.. _enum_Sky_RadianceSize:

.. rst-class:: classref-enumeration

enum **RadianceSize**:

.. _class_Sky_constant_RADIANCE_SIZE_32:

.. rst-class:: classref-enumeration-constant

:ref:`RadianceSize<enum_Sky_RadianceSize>` **RADIANCE_SIZE_32** = ``0``

Radiance texture size is 32×32 pixels.

.. _class_Sky_constant_RADIANCE_SIZE_64:

.. rst-class:: classref-enumeration-constant

:ref:`RadianceSize<enum_Sky_RadianceSize>` **RADIANCE_SIZE_64** = ``1``

Radiance texture size is 64×64 pixels.

.. _class_Sky_constant_RADIANCE_SIZE_128:

.. rst-class:: classref-enumeration-constant

:ref:`RadianceSize<enum_Sky_RadianceSize>` **RADIANCE_SIZE_128** = ``2``

Radiance texture size is 128×128 pixels.

.. _class_Sky_constant_RADIANCE_SIZE_256:

.. rst-class:: classref-enumeration-constant

:ref:`RadianceSize<enum_Sky_RadianceSize>` **RADIANCE_SIZE_256** = ``3``

Radiance texture size is 256×256 pixels.

.. _class_Sky_constant_RADIANCE_SIZE_512:

.. rst-class:: classref-enumeration-constant

:ref:`RadianceSize<enum_Sky_RadianceSize>` **RADIANCE_SIZE_512** = ``4``

Radiance texture size is 512×512 pixels.

.. _class_Sky_constant_RADIANCE_SIZE_1024:

.. rst-class:: classref-enumeration-constant

:ref:`RadianceSize<enum_Sky_RadianceSize>` **RADIANCE_SIZE_1024** = ``5``

Radiance texture size is 1024×1024 pixels.

\ **Note:** :ref:`RADIANCE_SIZE_1024<class_Sky_constant_RADIANCE_SIZE_1024>` is not exposed in the inspector as it is known to cause GPU hangs on certain systems.

.. _class_Sky_constant_RADIANCE_SIZE_2048:

.. rst-class:: classref-enumeration-constant

:ref:`RadianceSize<enum_Sky_RadianceSize>` **RADIANCE_SIZE_2048** = ``6``

Radiance texture size is 2048×2048 pixels.

\ **Note:** :ref:`RADIANCE_SIZE_2048<class_Sky_constant_RADIANCE_SIZE_2048>` is not exposed in the inspector as it is known to cause GPU hangs on certain systems.

.. _class_Sky_constant_RADIANCE_SIZE_MAX:

.. rst-class:: classref-enumeration-constant

:ref:`RadianceSize<enum_Sky_RadianceSize>` **RADIANCE_SIZE_MAX** = ``7``

Represents the size of the :ref:`RadianceSize<enum_Sky_RadianceSize>` enum.

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

.. _class_Sky_property_radiance_size:

.. rst-class:: classref-property

:ref:`RadianceSize<enum_Sky_RadianceSize>` **radiance_size** = ``2``

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

- void **set_radiance_size** **(** :ref:`RadianceSize<enum_Sky_RadianceSize>` value **)**
- :ref:`RadianceSize<enum_Sky_RadianceSize>` **get_radiance_size** **(** **)**

The **Sky**'s radiance map size. The higher the radiance map size, the more detailed the lighting from the **Sky** will be.

See :ref:`RadianceSize<enum_Sky_RadianceSize>` constants for values.

\ **Note:** You will only benefit from high radiance sizes if you have perfectly sharp reflective surfaces in your project and are not using :ref:`ReflectionProbe<class_ReflectionProbe>`\ s or :ref:`GIProbe<class_GIProbe>`\ s. For most projects, keeping :ref:`radiance_size<class_Sky_property_radiance_size>` to the default value is the best compromise between visuals and performance. Be careful when using high radiance size values as these can cause crashes on low-end GPUs.
