    Properties

    cascadeCount?: number

    Number of cascades for CSM (typically 3 or 4). Defaults to 4.

    cascadeSplitLambda?: number

    Factor weighting linear vs logarithmic cascade splits (value between 0 and 1). Defaults to 0.85.

    castShadow?: boolean

    Enable shadow depth map generation.

    color?: number[] | ColorLike

    Color of emitted light. Can be a Color instance, hex string, or RGB array. Defaults to #ffffff.

    csmMaxDistance?: number

    Maximum distance along camera depth for shadow mapping projection. Defaults to 100.0.

    innerAngle?: number

    Spotlight inner cone angle in degrees.

    intensity?: number

    Scalar multiplier for light emission intensity. Defaults to 1.0.

    outerAngle?: number

    Spotlight outer cone angle in degrees.

    position?: Vec3 | number[]

    Optional initial position of the light node in 3D space.

    radius?: number

    Radial size limit for point light attenuation.

    range?: number

    Spotlight physical distance range limit.

    rotation?: Vec3 | number[]

    Optional initial rotation Euler angles in radians.

    rotationDegrees?: Vec3 | number[]

    Optional initial rotation Euler angles in degrees.

    shadowBias?: number

    Shadow depth bias.

    shadowDepthRange?: number

    Total depth range along the Z axis of the shadow projection frustum. Defaults to 200.0.

    shadowMapSize?: number

    Shadow depth map resolution.

    shadowNear?: number

    Near clipping plane for perspective shadow projection.

    shadowRadius?: number

    World-space boundary half-extent defining the orthographic shadow view box. Defaults to 20.0.

    type?: "point" | "directional" | "spotlight"

    Light emitting style choice. Defaults to "directional".

    useCSM?: boolean

    If true, the directional light will use Cascaded Shadow Maps (CSM) to divide the frustum. Defaults to false.

    usePCF?: boolean

    Enable PCF filtering.
