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

Параметры рендера

-b, --background

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

The audio device is disabled in background-mode by default and can be re-enabled by passing in -setaudio Default afterwards.

-a, --render-anim

Render frames from start to end (inclusive).

-S, --scene <name>

Установите <имя> активной сцены для рендера.

-f, --render-frame <frame>

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 .. separator between the first and last frames (inclusive).

-s, --frame-start <frame>

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

-e, --frame-end <frame>

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

-j, --frame-jump <frames>

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

-o, --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.

• animation_##_test.png becomes animation_01_test.png

• test-######.png becomes test-000001.png

When the filename does not contain #, the suffix #### is added to the filename.

Номер кадра будет добавлен в конце имени файла, например:

blender -b animation.blend -o //render_ -F PNG -x 1 -a

//render_ becomes //render_####, writing frames as //render_0001.png

-E, --engine <engine>

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

-t, --threads <threads>

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

Other Options

--disable-depsgraph-on-file-load

Backround mode: Do not systematically build and evaluate ViewLayers“ dependency graphs when loading a blendfile in background mode (-b or -c options).

Scripts requiring evaluated data then need to explicitly ensure that an evaluated depsgraph is available (e.g. by calling depsgraph = context.evaluated_depsgraph_get()).

NOTE: this is a temporary option, in the future depsgraph will never be automatically generated on file load in background mode.

--disable-liboverride-auto-resync

Do not perform library override automatic resync when loading a new blendfile.

NOTE: this is an alternative way to get the same effect as when setting the No Override Auto Resync User Preferences Debug option.

Argument Parsing

Arguments must be separated by white space, eg:

blender -ba test.blend

…will exit since -ba is an unknown argument.

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.
