Multi-character AI consistency without face or wardrobe swaps

Treat each person as a separate identity system

Multi-character prompts fail when identity descriptions are blended into one paragraph. Assign a stable label, reference, wardrobe logic, and screen position to every person. The model needs to know which face, clothing, and action belong together.

• Character A: reference, fixed traits, wardrobe, left-side position.
• Character B: reference, fixed traits, wardrobe, right-side position.
• Shared scene: environment, camera, interaction, and lighting.

Prove the pair before adding complexity

Start with a simple medium shot where both faces and outfits are readable. Once the pairing is reliable, use that accepted frame as the reference for wider locations, movement, and editorial lighting. Complex choreography should come after identity has been proven.

Repair the swapped element only

If one face or outfit drifts, preserve the accepted composition and correct the specific character. Regenerating the whole scene often fixes one person while damaging the other. Narrow edits protect the parts that already work.

• Restate the affected character label and reference.
• Name the exact feature or garment to restore.
• Explicitly preserve the other character and current framing.
