enum **RadianceSize**:

- **RADIANCE_SIZE_32** = **0** --- Radiance texture size is 32×32 pixels.

- **RADIANCE_SIZE_64** = **1** --- Radiance texture size is 64×64 pixels.

- **RADIANCE_SIZE_128** = **2** --- Radiance texture size is 128×128 pixels.

- **RADIANCE_SIZE_256** = **3** --- Radiance texture size is 256×256 pixels.

- **RADIANCE_SIZE_512** = **4** --- Radiance texture size is 512×512 pixels.

- **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.

- **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.

- **RADIANCE_SIZE_MAX** = **7** --- Represents the size of the :ref:`RadianceSize<enum_Sky_RadianceSize>` enum.

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.
