NAME¶

blender - a 3D modelling and rendering package

SYNOPSIS¶

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

DESCRIPTION¶

blender 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 Dimensions. 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 versatile and extremely fast. All basic animation principles (curves & keys) are well implemented. http://www.blender.org

OPTIONS¶

Blender 2.63 (sub 0) 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 //render_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>

 

 

 

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

--env-system-scripts

 

Set the BLENDER_SYSTEM_SCRIPTS environment variable

 

 

--env-system-plugins

-R

 

Register .blend extension, then exit (Windows only)

 

 

-r

 

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

 

 

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.
