PolySpatial Grounding Shadow

This component provides a hint to the platform to cast a shadow from this object onto surfaces below, as if from a directional light pointing straight downwards. The object must have a MeshRenderer component. The PolySpatial Grounding Shadow component acts as a direct proxy to RealityKit's GroundingShadowComponent on visionOS, and is not available on other platforms, such as in Unity play mode.
