2D Animation Once the animatic has been approved, it and the storyboards are sent to the design departments. Character designers prepare model sheets for all important characters and props in the film; these are used to help standardize appearance, poses, and gestures. These model sheets will show how a character or object looks from a variety of angles with a variety of poses and expressions so that all artists working on the project can deliver consistent work. Sometimes, small statues known as maquettes may be produced, so that an animator can see what a character looks like in three dimensions. At the same time, the background stylists will do similar work for the settings and locations in the project, and the art directors and color stylists will determine the art style and color schemes to be used. While design is going on, the timing director (who in many cases will be the main director) takes the animatic and analyzes exactly what poses, drawings, and lip movements will be needed on what frames. An exposure sheet (or X-sheet for short) is created; this is a printed table that breaks down the action, dialogue, and sound frame-by-frame as a guide for the animators. If a film is based more strongly in music, a bar sheet may be prepared in addition to or instead of an X-sheet.[1] Bar sheets show the relationship between the on-screen action, the dialogue, and the actual musical notation used in the score.
