higgsfield-facs

Controls facial expressions in Seedance 2.0 with FACS (Facial Action Coding System) Action Unit codes — muscle-level direction (AU12 = lip-corner puller, AU6 = cheek raiser) instead of emotion labels. Use whenever the user wants precise facial acting, a forced/uncanny/mixed expression, micro-performance in a close-up, monologue or dialogue facial beats, a 'which AU code for anger/fear/disgust' answer, or to generate a FACS reference sheet for a character. Pairs with higgsfield-soul Micro-Expressions (named expressions), higgsfield-audio (dialogue + lip-sync), and higgsfield-gpt-image-2 (the reference-sheet image).

# Higgsfield FACS Director

Direct a face the way an animator does — by **muscle**, not by mood. FACS (the
Facial Action Coding System) names each facial movement as an **Action Unit**:
`AU12` is the lip-corner puller (smile), `AU6` is the cheek raiser, `AU4` is the
brow lowerer. Put those codes in a Seedance 2.0 prompt and the model renders the
corresponding action. It is the highest-resolution facial control available on
the platform, and it is where forced smiles, uncanny faces, mixed emotions, and
honest micro-performance in close-up dialogue come from.
