Argumentos de la línea de comandos#

Blender |VERSIÓN_DE_BLENDER|

Uso: blender [args ...] [archivo] [args ...]

Opciones de procesamiento#

-b, --background

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

-a, --render-anim

Render frames from start to end (inclusive).

-S, --scene <nombre>

Define la escena activa <nombre> para que sea procesada.

-f, --render-frame <fotograma>

Procesará el fotograma <fotograma> y lo guardará.

+<fotograma> fotograma de inicio relativo, -<fotograma> fotograma de fin relativo.
También será posible usar una lista de fotogramas separados por comas (sin espacios).
Se podrá definir un rango de fotogramas usando el separador .. entre el primer y último fotograma (que estará incluido).

-s, --frame-start <fotograma>

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

-e, --frame-end <fotograma>

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

-j, --frame-jump <fotogramas>

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

-o, --render-output <ruta>

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.

prueba_##_animación.png se transformará en prueba_01_animación.png
prueba-######.png se transformará en prueba-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 animation.blend -o //render_ -F PNG -x 1 -a

//anim_ se transformará en //anim_####, guardando fotogramas como //anim_0001.png

-E, --engine <motor>

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

-t, --threads <hilos>

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

Opciones de procesamiento con Cycles#

Cycles add-on options must be specified following a double dash.

--cycles-device <dispositivo>

Establece el dispositivo usado para el procesamiento. Las opciones válidas son: CPU CUDA OPTIX HIP ONEAPI METAL.

Anexar +CPU a un dispositivo GPU para procesar tanto en CPU como en GPU.

-x, --use-extension <booleana>

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

Opciones de reproducción de animación#

-a <opciones> <archivo(s)>

Instead of showing Blender’s user interface, this runs Blender as an animation player, to view movies and image sequences rendered in Blender (ignored if -b is set).

Argumentos de reproducción:

--python-use-system-env: Allow Python to use system environment variables such as PYTHONPATH and the user site-packages directory.
--addons <complemento(s)>: Comma separated list (no spaces) of add-ons to enable in addition to any default add-ons.

Opciones de registro#

--log <coincidencia>: 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. Sub-string can be matched using a * prefix and suffix, so --log "*undo*" logs every kind of undo-related message. Use «^» prefix to ignore, so --log "*,^wm.operator.*" logs all except for wm.operators.* Use «*» to log everything.
--log-level <nivel>: 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).

Procesamiento de los argumentos#

Los argumentos deberá estar separados por espacios en blanco, p.ej:

blender -ba test.blend

…will exit since -ba is an unknown argument.

Orden de los argumentos#

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.
