Light source component.

Attach to an entity with a transform to illuminate the scene. The transform’s -Z axis defines the light direction (for directional and spot lights).

Fields

light_type: LightType

The type of light (directional, point, spot, or area).

color: Matrix<f32, Const<3>, Const<1>, ArrayStorage<f32, 3, 1>>

Light color as linear RGB.

intensity: f32

Light intensity (lumens for point/spot, lux for directional).

range: f32

Maximum range for point/spot lights (0 = unlimited).

inner_cone_angle: f32

Inner cone angle in radians for spot lights (full intensity).

outer_cone_angle: f32

Outer cone angle in radians for spot lights (zero intensity).

cast_shadows: bool

Whether this light casts shadows.

shadow_bias: f32

Depth bias to reduce shadow acne artifacts.

shadow_resolution: u32

Per-light shadow map resolution. 0 falls back to the renderer default.

shadow_distance: f32

Maximum distance at which this light casts shadows. 0 = unlimited.

cookie_texture: Option<String>

Optional cookie texture path (IES profile or projected mask).

area_shape: AreaLightShape

Emitter shape for LightType::Area. Ignored for other light types.

area_width: f32

Width of a rectangular area light, or length of a tube light.

area_height: f32

Height of a rectangular area light.

area_radius: f32

Radius of a disk, sphere, or tube area light.

area_two_sided: bool

Whether a rectangular or disk area light emits from both faces.

area_emissive_texture: Option<String>

Optional emissive texture projected across a rectangular area light.

shadow_normal_bias: f32

Normal-offset bias in shadow texels, reducing acne on sloped surfaces.

shadow_softness: f32

Shadow penumbra softness (PCSS light-size scale). Larger is softer.

Implementations
