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 visualizations, and scientific visualizations.

OPTIONS

       Color management: using fallback mode for management Color  management:  Error  could  not
       find role data role.  Blender 3.0.1 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.

              * '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:

   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).

              Playback Arguments:

              -f <fps> <fps-base>
                Specify FPS to start with.
              -j <frame>
                Set frame step to <frame>.

   Other Options:
       --debug-freestyle
              Enable debug messages for Freestyle.

   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.
