I have been banging my head trying to get a simple pixellate pass (based on https://github.com/lachlanhurst/SCNTechniqueTest)work with a basic SCNPlane displaying a PNG and rendererd through a SCNRenderer. All I see is a black screen. If I use a SCNView instead of a SCNRenderer everything looks correct.
This is the only forum post that seems to vaguely relate, but since most of my SceneKit problems generate zero messages in the console I'm not really sure if there is a connection.

Has anybody gotten this ******** working?
