How to Build Expression Sheets with Copilot
Build expression sheets with Copilot and ToolRouter. Generate a complete set of character emotions for animation, visual novels, and game dialogue.
Tool
Generate a complete set of facial expressions for any character for animation, visual novels, and dialogue systems. Copilot is effective when expression sheet creation is part of a larger character production workflow that needs assets documented and filed immediately.

Steps
Once connected (see setup above), use the Character Sheet Maker tool:
- Upload the character design and specify the emotion states and output format required.
- Run `expression_sheet` through `character-sheet-maker` to generate the expression set.
- Ask Copilot to document the sheet — emotion labels, usage context, and file naming — for the asset library.
- File the expression set with documentation for use by the animation and writing teams.
Example Prompt
Try this with Copilot using the Character Sheet Maker tool
Use character-sheet-maker to create an expression sheet for this character with 6 core emotions. Return each expression as a separate file with the naming format character-name-emotion and document the intended use context for each in a short reference note.
Tips
- Name files with the character name and emotion label — it prevents confusion when multiple characters share a similar expression.
- Ask Copilot to confirm the file dimensions match the engine or platform requirements before filing.
- Keep the base character design in the same folder as the expression sheet for easy version tracking.
