Những Đối Số Dòng Lệnh (Command Line Arguments)

Blender 3.6 Usage: blender [args ...] [file] [args ...]

Tùy Chọn Kết Xuất (Render Options)

-b, "--background"

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

-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.

  • 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

Phân Tích Đối Số (Argument Parsing)

Arguments must be separated by white space, eg:

blender -ba test.blend

...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 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

...hoạt động như mong muốn.
