Property Descriptions

Color color = Color(1, 1, 1, 1) 🔗

void set_color(value: Color)
Color get_color()

The Color of the light. Defaults to white. A black color causes the light to have no effect.

float inner_cone_angle = 0.0 🔗

void set_inner_cone_angle(value: float)
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 SpotLight3D, the ratio between the inner and outer cone angles is used to calculate the attenuation of the light.

float intensity = 1.0 🔗

void set_intensity(value: float)
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.

String light_type = "" 🔗

void set_light_type(value: String)
String get_light_type()

The type of the light. The values accepted by Godot are “point”, “spot”, and “directional”, which correspond to Godot’s OmniLight3D, SpotLight3D, and DirectionalLight3D respectively.

float outer_cone_angle = 0.785398 🔗

void set_outer_cone_angle(value: float)
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 SpotLight3D, the outer cone angle is used as the angle of the spotlight.

float range = inf 🔗

void set_range(value: float)
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.
