Keeping the same person across clips

Set up a run so a campaign reads as one person, and know where identity still drifts.

What holds the person steady

Two things keep a campaign looking like one human. The face comes from a single reference-pack Person image, rebuilt into a character model sheet that seeds every clip. And each clip is one continuous take, so the face cannot morph halfway through. Pin the Person once and every render in the run casts from the same source.

The honest limit

This is a guard, not a promise. Identity can still drift across longer clips, and more visibly from one run to the next. The video model rebuilds the face from your reference every single time; it is not replaying a saved actor. Picture asking a skilled sketch artist to draw the same person from memory twice. The two drawings come out close, not identical. A fifteen-second clip holds better than a thirty-second one, and two runs on different days can come back as slightly different people.

How to work with it

When a tight match matters, keep clips shorter. Render everything for one campaign in the same sitting rather than weeks apart. Reuse the exact same Person image instead of a fresh photo of the same person, because a different source photo is a different starting point for the model. If one clip in a set drifts, re-run that one clip, not the whole batch.

If a render comes back looking like someone else, that is the drift limit showing, not a mistake you made. Treat the reference pack as your anchor and leave it alone.
