Drawings made in the development of character and mecha designs for animation, comics, and other artistic works where the same character or device needs to be drawn repeatedly. Used to finalize a character design, and provide a set-in-stone standard for reference by entire teams of animators and storyboard artists. Despite the name, there is usually more than one sheet involved. Sometimes called control art. It's based off the last revision of the Concept Art. There's a set done for every costume and hairstyle used for every character in a series, with varying levels of detail. The cost associated with this is a big reason for an Economy Cast who appears in a Limited Wardrobe. If the artists wander away from it, they have gone "Off-Model".
A set of these will also exist as a guide for the model maker in a 3D CGI production.
Some typical drawings found in model sheets:
- Turnarounds: Drawings of a character from multiple angles in the same pose, usually face on, three-quarters to both sides, profiles, and rear.
- Details on particular parts of the costume or face that might be confusing on the main overviews.
- An expression chart.
- A phoneme chart, showing the ten mouth shapes needed to convey realistic dialogue and lip sync (The Preston-Blair set).
- A height comparison and scale chart. This is typically a reproduction of the front views from the turnaround for each character, with characters arranged side by side like a police lineup: common ground line, with parallel lines at the apex of each head. Typically, the main character is reproduced on each page as a yardstick. Needed to prevent wonky scale.
- Character proportions, such as a chart illustrating characters' proportions, to ensure that proportions remain consistent throughout the work.
