Tehtävän asetukset

-b, --background

Run in background (often used for UI-less rendering).

-a, --render-anim

Render frames from start to end (inclusive).

-S, --scene <name>

Set the active scene <name> for rendering.

-f, --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, --frame-start <frame>

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

-e, --frame-end <frame>

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

-j, --frame-jump <frames>

Set number of frames to step forward after each rendered frame.

-o, --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

//render_ becomes //render_####, writing frames as //render_0001.png

-E, --engine <engine>

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

-x, --use-extension <bool>

Set option to add the file extension to the end of the file.

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).

--addons <addon(s)>

Comma separated list (no spaces) of add-ons to enable in addition to any default add-ons.

Logging Options

--log <match>

Enable logging categories, taking a single comma separated argument. Multiple categories can be matched using a .* suffix, so --log "wm.*" logs every kind of window-manager message. Sub-string can be matched using a * prefix and suffix, so --log "*undo*" logs every kind of undo-related message. Use ”^” prefix to ignore, so --log "*,^wm.operator.*" logs all except for wm.operators.* Use ”*” to log everything.

--log-level <level>

Set the logging verbosity level (higher for more details) defaults to 1, use -1 to log all levels.

--log-show-basename

-v, --version

--

End option processing, following arguments passed unchanged. Access via Python’s sys.argv.

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.
