var lightSize: Float { get set }Discussion
Larger values widen the penumbra and lengthen the transition between fully-shadowed and fully-lit regions, approximating the way an area light of that radius would shade a scene. The default value is 0.1.
This property has no effect when quality is low, which always produces a hard-edged shadow.
