Step 2: Generate Character Sheets of your favourite characters.

I took Lucia and Jason from GTA6, took the images from the official screenshots and fed it to ChatGPT with the given prompt to generate Character Sheets.

Create a professional character reference sheet based strictly on the attached reference image(s). Preserve the subject’s exact identity and defining traits across every panel: face shape, apparent age, skin tone and texture, hairstyle and color, body proportions, clothing, accessories, footwear, and any visible distinguishing features. Do not redesign, beautify, age-shift, gender-swap, or change the character.

Use a pure deep neutral-grey (#3a3a3c) seamless studio background. Create a clean editorial layout in a horizontal landscape composition, arranged left to right in three vertical sections. Keep lighting, lens look, color grading, styling, and character identity perfectly consistent in every panel.

— COLUMN 1 (largest, left): chest-up front portrait. Frame the head and upper chest; eyes in sharp focus with soft natural catchlights. Neutral, calm expression matching the reference.

— COLUMN 2 (center): full-body front view. Neutral relaxed A-pose, arms slightly away from the body, balanced stance, full figure visible from head to toe with even margins.

— COLUMN 3 (right): full-body back view. Same stance seen from behind, clearly showing hairstyle, back posture, garment fit, accessories, and footwear.

Lighting and render: soft, even studio lighting with a large diffused key and gentle fill; realistic natural shadows; true-to-reference skin tones; neutral white balance; polished modern model-sheet aesthetic; full-frame 85mm lens look; crisp, controlled detail; high dynamic range; high resolution.

No text, labels, logos, props, extra people, cropped limbs, duplicate body parts, pose changes, background scenery, or inconsistent facial features.

These are the results:

Step 3

Head over to Higgsfield Genjutsu, upload the base video and these character sheets, and ask it to swap the characters as shown

Prompt:

Replace the man on the left with @[Image 1](image_1) and the man on the right with @[Image 2](image_2). Keep the hairstyle same as in the images (Character Sheets) ... No logo in the bottom left, no speaker or box, keep the background (and stage) plain and going.
