SceneBackgroundRenderingLayer Property

Gets a RenderingLayer that is rendered first. Objects in this layer are not sorted and are rendered in the same order as they are added to the layer. To render the objects in this rendering layer behind all objects from other RenderingLayers, set the ClearDepthStencilBufferAfterRendering to true. This will clear the depth buffer so all objects in the following rendering layers will be rendered on top of the objects in BackgroundRenderingLayer (regardless of their depth).

public RenderingLayer? BackgroundRenderingLayer { get; }
