-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>"

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.

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
