How to stop the same character appearing twice in a generated scene
Tell Vizard Agent exactly how large the cast is and that no character may appear twice. It reviews the film for duplicates, opens the frames where they are most likely, generates clean replacement artwork in the same design rather than cropping the extra copy away, and counts the cast again on every replacement.
What do you type into Vizard Agent?
Put the count in the sentence you send. A generated scene with six characters will quietly render seven, because "a group of animals helping" is a description, not a headcount. A duplicate isn't a matter of taste: it's a frame with one more of something than it should have, and Vizard Agent can check a number.
Prompt
What does Vizard Agent actually do?
The frames are inspected before anything is regenerated, so a scene is only rebuilt when it's genuinely wrong. The repair is new artwork matched to the established design, because a cropped or covered duplicate looks like what it is. An accessory that keeps drifting is composited onto the located face, where it can't change. In the session behind this article it:
- Reviewed the render of an animated story whose cast had multiplied across several scenes, then opened the late story images and original stills where duplicates were most likely.
- Generated clean replacement artwork in the established design and inspected each replacement for hidden duplicates as well as obvious ones.
- Mapped the original scene timings so replacements landed where the old frames were, and rebuilt the picture track with narration-matched scene boundaries.
- Confirmed the count of one monster and six unique animals, then replaced one last duplicated frame found in the final pass.
- Located a new character's face precisely and overlaid their spectacles as a graphic rather than regenerating them, then verified the accessory and the cast count in both scenes it appeared in.
When does this not work well?
Counting only helps where a correct number exists. Crowd scenes, background figures and stylised repetition are all cases where "one of each" is either meaningless or actively wrong, so the instruction has to be scoped to the characters that matter. Two characters with similar designs can also confuse the count.
Common questions
Will cropping the extra one out do? It changes the composition. Vizard Agent replaces the frame instead.
Can it keep an accessory in place? Yes. Vizard Agent overlays it on the located face rather than regenerating it.
Does the whole film get rebuilt? No. Vizard Agent replaces only the scenes that failed the count.
