BLENDER(1)BLENDER(1)NAMEblender - a 3D modelling and rendering package
SYNOPSISblender [args ...] [file] [args ...]
DESCRIPTIONblender is a 3D modelling and rendering package. It is 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 Dimen‐
sions.
Use Blender to create TV commercials, to make technical visualizations,
business graphics, to do some morphing, or design user interfaces. You
can easy build and manage complex environments. The renderer is versa‐
tile and extremely fast. All basic animation principles (curves & keys)
are well implemented.

OPTIONS
Blender 2.66 Usage: blender [args ...] [file] [args ...]
Render Options:
-b or --background <file>
Load <file> 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.
-s or --frame-start <frame>
Set start to frame <frame> (use before the -a argument)
-e or --frame-end <frame>
Set end to frame <frame> (use before the -a argument)
-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
//render_ becomes //render_####, writing frames as //ren‐
der_0001.png//
-E or --engine <engine>
Specify the render engine
use -E help to list available engines
Format Options:
-F or --render-format <format>
Set the render format, Valid options are...
TGA IRIS JPEG MOVIE IRIZ RAWTGA
AVIRAW AVIJPEG PNG BMP FRAMESERVER
(formats that can be compiled into blender, not available on all
systems)
HDR TIFF EXR MULTILAYER MPEG AVICODEC QUICKTIME CINEON DPX
DDS
-x or --use-extension <bool>
Set option to add the file extension to the end of the file
-t or --threads <threads>
Use amount of <threads> for rendering in background
[1-64], 0 for systems processor count.
Animation Playback Options:
-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 (Don't 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>
Window Options:
-w or --window-border
Force opening with borders (default)
-W or --window-borderless
Force opening without borders
-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)
Game Engine Specific Options:
-g Game Engine specific options
-g fixedtime Run on 50 hertz without dropping frames
-g vertexarrays Use Vertex Arrays for rendering (usually faster)
-g nomipmap No Texture Mipmapping
-g linearmipmap Linear Texture Mipmapping instead of Nearest
(default)
Misc Options:
-d or --debug
Turn debugging on
* Prints every operator call and their arguments
* Disables mouse grab (to interact with a debugger in some
cases)
* Keeps python sys.stdin rather than setting it to None
--debug-fpe
Enable floating point exceptions
--disable-crash-handler
Disable the crash handler
--factory-startup
Skip reading the "startup.blend" in the users home directory
--env-system-datafiles
Set the BLENDER_SYSTEM_DATAFILES environment variable
--env-system-scripts
Set the BLENDER_SYSTEM_SCRIPTS environment variable
--env-system-python
Set the BLENDER_SYSTEM_PYTHON environment variable
-nojoystick
Disable joystick support
-noglsl
Disable GLSL shading
-noaudio
Force sound system to None
-setaudio
Force sound system to a specific device
NULL SDL OPENAL JACK
-h or --help
Print this help text and exit
-y or --enable-autoexec
Enable automatic python script execution, (default)
-Y or --disable-autoexec
Disable automatic python script execution (pydrivers & startup
scripts)
-P or --python <filename>
Run the given Python script file
--python-text <name>
Run the given Python script text block
--python-console
Run blender with an interactive console
--addons
Comma separated list of addons (no spaces)
-v or --version
Print Blender version and exit
--
Ends option processing, following arguments passed unchanged.
Access via python's sys.argv
Other Options:
/?
Print this help text and exit (windows only)
--debug-python
Enable debug messages for python
--debug-events
Enable debug messages for the event system
--debug-handlers
Enable debug messages for event handling
--debug-wm
Enable debug messages for the window manager
--debug-all
Enable all debug messages (excludes libmv)
--debug-value <value>
Set debug value of <value> on startup
--debug-jobs
Enable time profiling for background jobs.
--verbose <verbose>
Set logging verbosity level.
-R
Register .blend extension, then exit (Windows only)
-r
Silently register .blend extension, then exit (Windows only)
--no-native-pixels
Do not use native pixel size, for high resolution displays (Mac‐
Book 'Retina')
Argument Parsing:
arguments must be separated by white space. eg
"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
Argument Order:
Arguments are executed in the order they are given. eg
"blender --background test.blend --render-frame 1 --render-out‐
put /tmp"
...will not render to /tmp because '--render-frame 1' renders
before the output path is set
"blender --background --render-output /tmp test.blend --ren‐
der-frame 1"
...will not render to /tmp because loading the blend file over‐
writes the render output that was set
"blender --background test.blend --render-output /tmp --ren‐
der-frame 1" works as expected.
