Back to Oren-Nayar for diffuse...

Going to have to make a special screenshot capture task/job for HMD now as Linux fullscreen on DK2 flips W/H.  I had to jump out of fullscreen mode and take the HMD off to take these quick shots.  UI is fully working with navigation controller now at least.  Next stop is improved movement controls for walking around the scene, and of course move grasping and scene interaction using physics.  Also I fixed billboards ( eg particle fire ) to face HMD per eye, but they look horrible close up.   :)
