PlanarShadowRenderingProviderCustomShadowLight Property

When CustomShadowLight is set, then it is used as a light that generates the shadow instead of a light from a 3D scene. This way it is possible to generate a shadow from a light that does not illuminate the scene. The only possible types of lights that can be assigned to this property are PointLight and DirectionalLight. It is also possible to use a custom light with overriding the CalculateShadowMatrix method.
