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.

Disallow internet access, overriding the preference.

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.

-v, --version

Print Blender version and exit.


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

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.
