<member name="color" type="Color" setter="set_color" getter="get_color" default="Color(1, 1, 1, 1)" keywords="colour">
The [Color] of the light. Defaults to white. A black color causes the light to have no effect.
</member>
<member name="inner_cone_angle" type="float" setter="set_inner_cone_angle" getter="get_inner_cone_angle" default="0.0">
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.
</member>
<member name="intensity" type="float" setter="set_intensity" getter="get_intensity" default="1.0">
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.
</member>
<member name="light_type" type="String" setter="set_light_type" getter="get_light_type" default="""">
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.
</member>
<member name="outer_cone_angle" type="float" setter="set_outer_cone_angle" getter="get_outer_cone_angle" default="0.785398">
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.
</member>
<member name="range" type="float" setter="set_range" getter="get_range" default="inf">
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.
