       blender - a 3D modelling and rendering package

       blender [args ...] [file] [args ...]

       blender is a 3D modelling and rendering package. It is the in-house
       software of a high quality animation studio, Blender has proven to be an
       extremely fast and versatile design instrument. The software has a
       personal touch, offering a unique approach to the world of Three

       Use Blender to create TV commercials, to make technical visualizations,
       business graphics, to do some morphing, or design user interfaces. You
       can easy build and manage complex environments. The renderer is versatile
       and extremely fast. All basic animation principles (curves & keys) are
       well implemented.

       Blender 2.66 Usage: blender [args ...] [file] [args ...]

   Render Options:
       -b or --background <file>
              Load <file> in background (often used for UI-less rendering)

       -a or --render-anim
              Render frames from start to end (inclusive)

       -S or --scene <name>
              Set the active scene <name> for rendering

       -f or --render-frame <frame>
              Render frame <frame> and save it.
              +<frame> start frame relative, -<frame> end frame relative.

       -s or --frame-start <frame>
              Set start to frame <frame> (use before the -a argument)

       -e or --frame-end <frame>
              Set end to frame <frame> (use before the -a argument)

       -j or --frame-jump <frames>
              Set number of frames to step forward after each rendered frame

       -o or --render-output <path>
              Set the render path and file name.
              Use // at the start of the path to
                  render relative to the blend file.
              The # characters are replaced by the frame number, and used to
              define zero padding.
                  ani_##_test.png becomes ani_01_test.png
                  test-######.png becomes test-000001.png
                  When the filename does not contain #, The suffix #### is added
              to the filename
              The frame number will be added at the end of the filename.
                  eg: blender -b foobar.blend -o //render_ -F PNG -x 1 -a
                  //render_ becomes //render_####, writing frames as

   Argument Parsing:
           arguments must be separated by white space. eg
               "blender -ba test.blend"
           ...will ignore the 'a'
               "blender -b test.blend -f8"
           ...will ignore 8 because there is no space between the -f and the
       frame value

   Argument Order:
       Arguments are executed in the order they are given. eg
               "blender --background test.blend --render-frame 1 --render-output
           ...will not render to /tmp because '--render-frame 1' renders before
       the output path is set
               "blender --background --render-output /tmp test.blend
       --render-frame 1"
           ...will not render to /tmp because loading the blend file overwrites
       the render output that was set
               "blender --background test.blend --render-output /tmp
       --render-frame 1" works as expected.

         BLENDER_USER_SCRIPTS Directory for user scripts.
         BLENDER_SYSTEM_SCRIPTS Directory for system wide scripts.
         Directory for user data files (icons, translations, ..).
