blender

Command-line interface to the Blender 3D computer graphics application.

Arguments are executed in the order they are given.

More information.

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

blender --background {filename}.blend --render-anim

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

blender --background {filename}.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 {filename}.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 {filename}.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 {filename}.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 {filename}.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
