HitTestOptionsOverlayRenderingLayer Property

When OverlayRenderingLayer is specified, then the objects that are assigned to that rendering layer will be considered closer to the camera than objects from other rendering layers. This means that the GetClosestHitObject method will return objects from the specified rendering queue even if in 3D space they are behind objects from other rendering layers. When calling GetAllHitObjects, then this property does not have effect.

public RenderingLayer? OverlayRenderingLayer { get; set; }
