The sky does not go into the color buffer and that is not what he said to do.
Draw the color buffer without the sky, combine all the buffers, then add the sky afterwards.
Hey! Sorry, I seem to be lacking a little attention to detail today. Haha, anyways, I believe I've now done what he has said.
void NXRTDeferredShading::Finalize(const NXStopwatch& gameTime)
RenderTargets.Clear(0, 0, 0, 0);
After setting to render to my fourth target (putting final image in separate buffer for post process purposes; I'd like to the skybox to affected by motion blur as well), I render my quad with my combine shader, and I render outside objects (my skybox). As a result, I only see my skybox. I've tried setting a blend state and rendering, and only saw the slightly transparent lit face of the cube but the skybox was still rendered correctly. I've updated the dropbox.
