Blender's story tools combine Grease Pencil and the Video Sequence Editor to let story artists sketch 2D drawings over 3D environments, block out camera movements, and assemble sequences in one place.
This integrated workflow eliminates switching between separate drawing, 3D, and editing applications, allowing artists to rapidly iterate on shot composition and timing while staying entirely within Blender.
Currently available: Introduction and 2D Storyboarding sections. The 2.5D Storyboarding section is coming soon.
