NAME

blender - a 3D modelling and rendering package

SYNOPSIS

blender [args ...] [file] [args ...]
 

DESCRIPTION

blender is a 3D modelling and rendering package. Originating as the in-house software of a high quality animation studio, Blender has proven to be an extremely fast and versatile design instrument. The software has a personal touch, offering a unique approach to the world of Three Dimensions.
 
Use Blender to create TV commercials, to make technical visualizations, business graphics, to create content for games, or design user interfaces. You can easy build and manage complex environments. The renderer is versatile and extremely fast. All basic animation principles (curves & keys) are well implemented.

OPTIONS

Color management: using fallback mode for management Blender 2.79 (sub 0) Usage: blender [args ...] [file] [args ...]
 

Render Options:

-b or --background
 
Run in background (often used for UI-less rendering)
 
 
-a or --render-anim
 
Render frames from start to end (inclusive)
 
 
-S or --scene <name>
 
Set the active scene <name> for rendering
 
 
-f or --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 '..' seperator between the first and last frames (inclusive).
 
 
 
-s or --frame-start <frame>
 
Set start to frame <frame>, supports +/- for relative frames too.

-o or --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.
 
 
* 'ani_##_test.png' becomes 'ani_01_test.png'
 
* 'test-######.png' becomes 'test-000001.png'
 
 
When the filename does not contain '#', The suffix '####' is added to the filename.

Argument Parsing:

Arguments must be separated by white space, eg:


# blender -ba test.blend
...will ignore the 'a'
# blender -b test.blend -f8
...will ignore '8' because there is no space between the '-f' and the frame value
 

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.
