        360 >>> 0
        359.9 >>> 359.9
        360.1 >>> 0.1
        If you rotate something 360 degrees it's the same as rotating it by 0 degrees...

          Hi,
          Tig you're right but you just specify it in the manuals or
          when I write 360° the program automatically reads 359.9999°.

          Thanks
          David

            I'd say that is a bug in vray?
            A hfov of 360 is pretty standard for a spherical, and with CGI you shouldn't really be limited by such rules/limits?
            Like with this photo-spherical that was rendered using Lightwaves advanced camera set at 360x520 degrees: http://worldwidepanorama.org/worldwidepanorama/wwp609/html/BjornKareNilssen-5626.html
            Set at hfov 720 degrees it would repeat the entire image twice horizontally.

              I see there's another problem. The more the number closer to 360° the more the picture is brighter. Does anyone know why?

                    PROBLEM SOLVED.
                    But first, the problem description: black output from v-ray for sketchup v1.491 when using a spherical camera with a 360 FOV and increased brightness towards this value. After searching wide and far, this was the only forum the problem was plainly defined by others, so, after tinkering with the vray options for a good while, here is the solution:
                    For reference, I had reseted options before applying the following:

                    CAMERA > SETTINGS CAMERA > Type=Spherical, Override FOV=360, ON
                    CAMERA > CameraPhysical > OFF (turn off the 'on' check box)

                    • this will solve the black image, but still increased brightness
                      OUTPUT > Image aspect=2.0, width=2 x height, use any values (like 800x400)
                      ENVIRONMENT > GI Color=0.0, checked ON
                      ENVIRONMENT > BG Color=1.0, checked ON
                    • this will solve the brightness problem

                    Cheers.
                    And BTW, 360 ain't 0, nor this is a bug, just a bad documented feature.

                      No, we actually do treat it as 0 for the physical camera. There are cameras out there that can do a 360 degree image or video, but they employ the use of multiple cameras and then stitch the images/video together. A physically accurate camera can't capture true 360 degrees with one lens.

                      absolutely not, you are correct

                      You again, are absolutely correct

                        I stand corrected.
