When posing 3D eye models for movies, align eye direction, blink timing, and micro-expressions with the character’s emotions and scene actions to keep the performance believable.
Eye direction should track the scene’s focus—like a co-star’s face or a moving object—since off-target eyes break immersion. Blink timing needs natural variation: fewer blinks when focused, more when nervous, to avoid robotic stiffness. Micro-expressions (e.g., slight squinting for doubt, widening for surprise) add emotional depth, especially in close-ups where small eye adjustments amplify feeling.
For new artists, use real actor reference footage (watching how human eyes react in similar scenes) to guide posing—it’s a simple way to make 3D eyes feel authentic.
