NAME
       blender - a full-featured 3D application

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

DESCRIPTION
       blender is a full-featured 3D application. It supports the entirety of
       the 3D pipeline - modeling, rigging, animation, simulation, rendering,
       compositing, motion tracking, and video editing.

       Use Blender to create 3D images and animations, films and commercials,
       content for games, architectural and industrial visualizatons, and
       scientific visualizations.

       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.


              * 'animation_##_test.png' becomes 'animation_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 animation.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.


   Format Options:
       -F or --render-format <format>
              Set the render format.
              Valid options are:

              systems:

   Animation Playback Options:
       -a <options> <file(s)>
              Instead of showing Blender's user interface, this runs Blender as
              an animation player,
              to view movies and image sequences rendered in Blender (ignored if
              '-b' is set).

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

   Argument Parsing:
        Arguments must be separated by white space, eg:
         # blender -ba test.blend
         ...will exit since '-ba' is an unknown argument.

   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.
