blender

Command-line interface to the Blender 3D computer graphics application. Arguments are executed in the order they are given. More information: https://docs.blender.org/manual/en/latest/advanced/command_line/arguments.html.

Render all frames of an animation in the background, without loading the UI (output is saved to /tmp):

blender --background {{path/to/file}}.blend --render-anim

Render an animation using a specific image naming pattern, in a path relative (//) to the .blend file:

blender --background {{path/to/file}}.blend --render-output //{{render/frame_###.png}} --render-anim

Render the 10th frame of an animation as a single image, saved to an existing directory (absolute path):

blender --background {{path/to/file}}.blend --render-output {{/path/to/output_directory}} --render-frame {{10}}

Render the second last frame in an animation as a JPEG image, saved to an existing directory (relative path):

blender --background {{path/to/file}}.blend --render-output //{{output_directory}} --render-frame {{JPEG}} --render-frame {{-2}}

Render the animation of a specific scene, starting at frame 10 and ending at frame 500:

blender --background {{path/to/file}}.blend --scene {{scene_name}} --frame-start {{10}} -e {{500}} --render-anim

Render an animation at a specific resolution, by passing a Python expression:

blender --background {{path/to/file}}.blend --python-expr '{{import bpy; bpy.data.scenes[0].render.resolution_percentage = 25}}' --render-anim

Start an interactive Blender session in the terminal with a python console (do import bpy after starting):

blender --background --python-console
