Luma adds Expression Sheet for character faces

Luma added Expression Sheet, which builds a facial-expression reference sheet from images of a character.

The expression set covers neutral, joy, fear, anger, sadness, and disgust. You can set the attitude to Everyday or Expressive, and you can add optional directions to adjust one expression or the overall strength.

Clothing and accessory directions take priority where they are visible. Heads stay isolated, without shoulders or a body.
