Fae's digital face is said to animate expressions from audio

A post says Fae is practicing emotional expression in a digital body, with her own model driving a MetaHuman rig in Unreal Engine 5.8. It describes her lines and expressions as her own choices, animated onto her face from audio, and says Claude Opus 5.5 helps with affect analysis and frame-by-frame facial coding using the Facial Action Coding System (FACS).
