  }

  • color: UniformNode<"vec3", Vector3>

    Light colour (linear).

  • density: UniformNode<"float", number>

    Procedural coverage.

  • intensity: UniformNode<"float", number>

    Radiance of fully lit areas (0 = off).

  • map: TextureNode<"vec4">

    Lights texture (equirectangular).

  • planetRadius: UniformNode<"float", number>

    Planet radius, metres (sets the size of the sparkle).

  • scale: UniformNode<"float", number>

    Procedural feature scale.

  • twilight: UniformNode<"vec3", Vector3>

    Sun-elevation sines where lights switch on (start, full).

  • useTexture: UniformNode<"float", number>

    1 = use the texture, 0 = procedural.

• bodyDir: any

  Unit direction from the planet centre in the body frame.

• sunDir: any

  Unit direction to the sun in the same frame.
