NAME

blender - a 3D modelling and rendering package

SYNOPSIS

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

DESCRIPTION

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.

OPTIONS

Color management: using fallback mode for management Blender 2.76 (sub 0) 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.

-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

-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
[1-64], 0 for systems processor count.

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

Animation Playback Options:
-a or --render-anim
Render frames from start to end (inclusive)

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), (Windows only)

--no-native-pixels
Do not use native pixel size, for high resolution displays (MacBook 'Retina')

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)

Python Options:
-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

--addons
Comma separated list of addons (no spaces)

Debug Options:
-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>
Set debug value of <value> on startup

--debug-events
Enable debug messages for the event system

--debug-ffmpeg
Enable debug messages from FFmpeg library

--debug-jobs
Enable time profiling for background jobs.

--debug-python

--debug-depsgraph
Enable debug messages from dependency graph

--debug-depsgraph-no-threads
Switch dependency graph to a single threaded evaluation

--debug-gpumem
Enable GPU memory stats in status bar

--debug-wm
Enable debug messages for the window manager, also prints every operator call

--debug-all
Enable all debug messages (excludes libmv)

--debug-fpe

--
Ends option processing, following arguments passed unchanged. Access via Python's

-R
Register .blend extension, then exit (Windows only)

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

Experimental features:
--enable-new-depsgraph
Use new dependency graph

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-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.
