      I rendered what may have been the first multi camera derived
      fulldome animations in 1998, and I still find that method far faster
      than trying to render a 4K fisheye view. This method is far from
      extinct, at least in my workshop.

        I tried to set up the fisheye shader in my system (windows xp, Maya
        8.0) and I can't get it to render properly (I get a black frame)...
        with both the atom and the ott versions...

        so I'm assuming either it doesn't work with Maya 8 or (more likely) I
        have misunderstood something in the directions for set up...

        anybody here using either atom or ott fisheye with Maya 8, and willing
        to help me troubleshoot?

          FinalRender, fisheye 180-200. If it was a dream of going back to 5
          cameras and stitching, I'd wake up in a cold sweat. It was ok for 1k
          and useable for 2k. But 4k would add so much time to the process I
          fear to think. With the 5 camera setup it was useful to have an extra
          45 degree tilt to play with. Then again, if you know what you want or
          you don't plan to adjust tilt for every dome, that extra rendering
          time is very wasteful.

            One little trick for all you out there rendering separate cameras and
            stitching is (assuming you do not want the bottom half of the lower
            cameras for tilt options) is to place a black plane near the cameras
            blocking out the lower half of the scene. Depending on what software
            you're using, applying a "simple" shader to that surface (one that
            has no shading qualities and renders quick) will save a lot of render
            time.
