A spotlight, such as a reflector spotlight or a lantern.

Description

A Spotlight is a type of 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 Light3D.

Property Descriptions

• float spot_angle

Default	45.0
Setter	set_param(value)
Getter	get_param()

The spotlight's angle in degrees.

---

• float spot_angle_attenuation

Default	1.0
Setter	set_param(value)
Getter	get_param()

The spotlight's angular attenuation curve.

---

• float spot_attenuation

Default	1.0
Setter	set_param(value)
Getter	get_param()

The spotlight's light energy attenuation curve.

---

• float spot_range

Default	5.0
Setter	set_param(value)
Getter	get_param()

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