blender - a 3D modelling and rendering package

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

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 7) 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.

* '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.

-F or --render-format <format>

Set the render format.
Valid options are 'TGA' 'RAWTGA' 'JPEG' 'IRIS' 'IRIZ' 'AVIRAW' 'AVIJPEG' 'PNG' 'BMP'

Formats that can be compiled into Blender, not available on all systems: 'HDR' 'TIFF' 'EXR' 'MULTILAYER'

-x or --use-extension <bool>

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

-a <options> <file(s)>

Playback <file(s)>, only operates this way when not running in background.

-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>.

-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.

-g Game Engine specific options

Run on 50 hertz without dropping frames.
Use Vertex Arrays for rendering (usually faster).
No Texture Mipmapping.
Linear Texture Mipmapping instead of Nearest (default).

-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-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

-r

Silently register blend-file extension, then exit (Windows only).

# 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.

# 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.
