blender - a full-featured 3D application

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

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.

Color management: using fallback mode for management Color management: Error could not find role data role. Blender 2.80 (sub 75) Usage: blender [args ...] [file] [args ...]

-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.

-F or --render-format <format>

Set the render format.
Valid options are:

Formats that can be compiled into Blender, not available on all systems:

-x or --use-extension <bool>

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

-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:

-p <sx> <sy> Open with lower left corner at <sx>, <sy>.
-m Read from disk (Do not buffer).
-f <fps> <fps-base> Specify FPS to start with.
-j <frame> Set frame step to <frame>.
-s <frame> Play from <frame>.
-e <frame> Play until <frame>.

-w or --window-border

Force opening with borders.

-W or --window-fullscreen

Force opening in fullscreen mode.

-p or --window-geometry <sx> <sy> <w> <h>

Open with lower left corner at <sx>, <sy> and width and height as <w>, <h>.

-M or --window-maximized

Force opening maximized.

-con or --start-console

Start with the console window open (ignored if '-b' is set), (Windows only).

--no-native-pixels

Do not use native pixel size, for high resolution displays (MacBook 'Retina').

--no-window-focus

Open behind other windows and without taking focus.

-y or --enable-autoexec

Enable automatic Python script execution.

-Y or --disable-autoexec

Disable automatic Python script execution (pydrivers & startup scripts), (compiled as non-standard default).

-P or --python <filename>

Run the given Python script file.

--python-text <name>

Run the given Python script text block.

--python-expr <expression>

Run the given expression as a Python script.

--python-console

Run Blender with an interactive console.

--python-exit-code <code>

Set the exit-code in [0..255] to exit if a Python exception is raised
(only for scripts executed from the command line), zero disables.

--addons <addon(s)>

Comma separated list of add-ons (no spaces).

--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.
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

Only show file name in output (not the leading path).

--log-show-backtrace

Show a back trace for each log message (debug builds only).

--log-show-timestamp

Show a timestamp for each log message in seconds since start.

--log-file <filename>

Set a file to output the log to.

-d or --debug

Turn debugging on.

* Enables memory error detection
* Disables mouse grab (to interact with a debugger in some cases)
* Keeps Python's 'sys.stdin' rather than setting it to None

--debug-value <value>

/?

Print this help text and exit (windows only).

--debug-freestyle

Enable debug messages for Freestyle.

--verbose <verbose>

Set logging verbosity level for debug messages which supports it.

# blender -ba test.blend ...will exit since '-ba' is an unknown argument.

# 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.
