Disabling background

[iBicha]

currently disabling ARCoreBackgroundRenderer does not disable background rendering for me.
The way to go is to set the ARBackgroundRenderer.mode to ARRenderMode.MaterialAsBackground when we want to enable it, and to ARRenderMode.StandardBackground when we want to disable it. It's a bad idea to do a null check on it every frame anyway, as it is unnecessary.

A piece of code I'm currently using as a hack, in another script on the camera:

private ARBackgroundRenderer m_BackgroundRenderer;
private ARCoreBackgroundRenderer m_ARCoreBackgroundRenderer;
private ARBackgroundRenderer BackgroundRenderer
{
    get
    {
        if(m_BackgroundRenderer == null || m_ARCoreBackgroundRenderer == null)
        {
            m_ARCoreBackgroundRenderer = GetComponent<ARCoreBackgroundRenderer>();
            if (m_ARCoreBackgroundRenderer != null)
            {
                System.Reflection.FieldInfo m_BackgroundRendererField = typeof(ARCoreBackgroundRenderer).GetField("m_BackgroundRenderer", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
                if (m_BackgroundRendererField != null)
                {
                    m_BackgroundRenderer = (ARBackgroundRenderer)m_BackgroundRendererField.GetValue(m_ARCoreBackgroundRenderer);
                }
            }
        }
        return m_BackgroundRenderer;
    }
}

And then:

BackgroundRenderer.mode = enabled ? ARRenderMode.MaterialAsBackground : ARRenderMode.StandardBackground;
