This leads me to believe that each composition I have will require its own renderer? However, in QCTV, each patch loaded has a billboard or a sprite, or, in other words, is an 'output' patch. Does each and every composition, regardless of whether it is a final output (destination patch?) require its own QCRenderer? If I have a QC patch with has a valueForOutputKey of Type:"QTImage", , perhaps a patch with a CIKernal, etc, or a patch with a Render to Image, does it require its own QCRenderer?
You are correct, each part requires its own QCRenderer. Your original question was asking if there was a procedural way to connect patches within compositions, which isn't possible with the public API. The closest supported approximation is thus connecting the outputs of QCRenderers to the inputs of other QCRenderers.
