Description
|
|
-----------
|
|
|
|
A Spotlight is a type of :ref:`Light3D<class_Light3D>` node that emits lights in a specific direction, in the shape of a cone. The light is attenuated through the distance. This attenuation can be configured by changing the energy, radius and attenuation parameters of :ref:`Light3D<class_Light3D>`.

The maximal range that can be reached by the spotlight. Note that the effectively lit area may appear to be smaller depending on the :ref:`spot_attenuation<class_SpotLight3D_property_spot_attenuation>` in use. No matter the :ref:`spot_attenuation<class_SpotLight3D_property_spot_attenuation>` in use, the light will never reach anything outside this range.
