A tiny interruption makes a face feel alive
A game character can have a carefully modeled face and still seem strangely lifeless if nothing ever changes. Real faces are never quite still: eyes shift, muscles move, and eyelids briefly close. A blink adds one of those small, familiar interruptions without requiring a character to speak or change expression.
In the setup described here, a hidden timer waits a few seconds, then briefly switches the eyes to a closed state for one frame—the single image the game displays before moving on. The game then returns the face to its open-eyed state. Because the timer is randomized, the blink does not arrive at the exact same interval every time.
Why the timing matters
A perfectly regular blink can look like a mechanical loop: once players notice the pattern, the face seems to be following a clock. Random timing makes the action less predictable, closer to the uneven rhythm of an ordinary person. It also lets the character remain visually still most of the time, so the blink is a subtle cue rather than a constant distraction.
The trick is small, but it changes how a static model reads. A face that occasionally closes its eyes feels less like a fixed picture and more like a body briefly interrupting its own stillness. The game does not need a complex facial performance to suggest that someone is there.
