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 --frame-end 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
