Blender 2.79 (sub 6)"


NAME
       blender - a 3D modelling and rendering package

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

DESCRIPTION
       blender is a 3D modelling and rendering package. Originating as 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
       Dimensions.

       Use Blender to create TV commercials, to make technical visualizations,
       business graphics, to create content for games, 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.

       Color management: using fallback mode for management Blender 2.79 (sub 6)
       Usage: blender [args ...] [file] [args ...]

   Render Options:
       -b or --background
              Run 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.
              * A comma separated list of frames can also be used (no spaces).
              * A range of frames can be expressed using '..' separator between
              the first and last frames (inclusive).


       -s or --frame-start <frame>
              Set start to frame <frame>, supports +/- for relative frames too.


       -e or --frame-end <frame>
              Set end to frame <frame>, supports +/- for relative frames too.


       -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


       -E or --engine <engine>
              Specify the render engine.
              Use -E help to list available engines.


       -t or --threads <threads>
              Use amount of <threads> for rendering and other operations
              [1-1024], 0 for systems processor count.

   Animation Playback Options:

              so '--log "wm.*"' logs every kind of window-manager message.
              Use "^" prefix to ignore, so '--log "*,^wm.operator.*"' logs all
              except for 'wm.operators.*'
              Use "*" to log everything.


       --log-level <level>

   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
       '/tmp'
         ...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.
