How to use custom shader effect with the background entity?

I need to apply some custom effect for the background entity.

I tried to use SceneDelegateRenderer for draw a PrimitiveQuad, but if I put it on Master (compositor.Master.Renderers.Add(renderer):wink: as last item - it visible only custom effect without another elements of the scene,
and if I put as first item(compositor.Master.Renderers.Insert(0,renderer):wink: it visible only another scene without background.
Please describe a technique how to use custom effect for the background entity. Maybe I did not understand renderer layers.

Or maybe, anybody know where can I read about this?

Hi byrakham,

You should add your custom renderer after the ClearFrameRenderer (probably position 1) or clear the depth buffer before drawing your quad. You may also want to disable the depth writing so that it does not impact later renderers.

Hope it will help
