Những Đối Số Dòng Lệnh (Command Line Arguments)¶

Blender 4.4

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

Tùy Chọn Kết Xuất (Render Options)¶

-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 -setaudo Default afterwards.

-a, "--render-anim"

Render frames from start to end (inclusive).

-S, "--scene" "<name>"

Set the active scene <name> for rendering.

-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.

The frame number will be added at the end of the filename, eg:

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.

Append +CPU to a GPU device to render on both CPU and GPU.

Example:

blender -b file.blend -f 20 -- --cycles-device OPTIX

Use "^" prefix to ignore, so --log "*,^wm.operator.*" logs all except for wm.operators.* Use "*" to log everything.

...will exit since -ba is an unknown argument.

Trật Tự của Đối Số (Argument Order)¶

Arguments are executed in the order they are given. eg:

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
