blender

a 3D modelling and rendering package

Blender 2.79 (sub 0)"

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 0) Usage: blender [args ...] [file] [args ...]


Run in background (often used for UI-less rendering).


Render frames from start to end (inclusive).


Set the active scene <name> for rendering.


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 '..' seperator between the first and last frames (inclusive).


Set start to frame <frame>, supports +/- for relative frames too.


Set end to frame <frame>, supports +/- for relative frames too.


Set number of frames to step forward after each rendered frame.


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


Specify the render engine.
Use -E help to list available engines.


Use amount of <threads> for rendering and other operations
[1-1024], 0 for systems processor count.


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'


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


Render frames from start to end (inclusive).


Force opening with borders.


Force opening without borders.


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


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


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


Run on 50 hertz without dropping frames.

Use Vertex Arrays for rendering (usually faster).

No Texture Mipmapping.

Linear Texture Mipmapping instead of Nearest (default).


Enable automatic Python script execution.


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


Run the given Python script file.


Run the given Python script text block.


Run the given expression as a Python script.


Run Blender with an interactive console.


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.


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


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


Set debug value of <value> on startup.


Enable debug messages for the event system.


Enable debug messages from FFmpeg library.


Enable debug messages for event handling.


Enable debug messages from libmv library.


Enable debug messages from Cycles.


Enable fully guarded memory allocation and debugging.


Enable time profiling for background jobs.


Enable debug messages for Python.


Enable debug messages from dependency graph.


Switch dependency graph to a single threaded evaluation.


Enable GPU memory stats in status bar.


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


Enable all debug messages.


Enable debug messages for I/O (collada, ...).


Enable floating point exceptions.


Disable the crash handler.


Skip reading the BLENDER_STARTUP_FILE in the users home directory.


Set the BLENDER_SYSTEM_DATAFILES environment variable.


Set the BLENDER_SYSTEM_SCRIPTS environment variable.


Set the BLENDER_SYSTEM_PYTHON environment variable.


Disable joystick support.


Disable GLSL shading.


Force sound system to None.


Force sound system to a specific device.


Print this help text and exit.


Print Blender version and exit.

--

End option processing, following arguments passed unchanged. Access via Python's 'sys.argv'.


Use new dependency graph.


Use new GLSL basic shader.

/?

Print this help text and exit (windows only).


Disable the abort handler.


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>.


Enable debug messages for FreeStyle.


Enable gpu debug context and information for OpenGL 4.3+.


Set logging verbosity level.


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


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.
