Build a character sheet and keep it consistent across scenes

Design one original character, derive a turnaround, an expression sheet and an outfit sheet from her, then place her in new scenes and next to a second character without her face, hair or clothes drifting.

About this use case

One original character, built once and reused everywhere. Part 1 makes an approved hero image and three sheets (turnaround, expressions, outfits). Part 2 attaches those sheets to put her in four different scenes with no drift in face, hair or clothes. Part 3 adds a second character and stages both together without their identities mixing. Anyone who will later ask a model for "the same character again" attaches this pack to every scene, pose and mesh. The models and settings in this use case are as of October 2026.

  • One approved hero and three sheets (turnaround, expressions, outfits) fix an original character's identity; the same pack then puts her in new scenes and next to a second character.
  • Generate every sheet and scene from the approved hero as a reference with a named role, paste one keep-list verbatim, and change only the scene.
  • With two characters, label each reference with a name, repeat each keep-list under it, and write who stands where.
Step by step with an agent, through the Scenario MCP (7 steps)Hide the steps
  1. Connect the Scenario MCP

    Connect your agent to the Scenario MCP and sign in once at mcp.scenario.com. Then tell it which Scenario team and project to use for the session, so every output lands there.

  2. Give the agent the files

    Nothing to upload to start: the character is written in the brief. From the second step on, the agent passes the approved images by their asset IDs, always as an array in referenceImages, even for one image; a bare value is ignored and you get a new character instead.

  3. Brief the agent: the hero

    Describe her once, in full, and get two takes to choose from. Then fix the text, not the image: both takes in the run put the chevron on her right sleeve, so the keep-list says "right sleeve" from here on.

    Prompt
    Use GPT Image 2.5 Sunburst (model_openai-gpt-image-2-5-sunburst): width 1024, height 1536, quality high, numOutputs 2. No reference. Quote the cost with a dry run first and wait for my go.
    
    Prompt, word for word:
    Original game character concept, full body, standing in a relaxed A-pose, three-quarter front view, feet fully visible, centered on a plain light warm-grey background. Character: Zuri Vex, a 22-year-old roller-blade sprinter hero. Warm brown skin, confident grin, long box braids tied high with glowing cyan tips, small silver hoop earrings. Cropped magenta bomber jacket with cyan piping and a white chevron on the left shoulder, black athletic top, fingerless black gloves. Charcoal tech leggings, white knee guards, inline roller blades with four glowing cyan wheels each. Two compact white-and-black pulse blasters holstered on her thighs. Empty hands, arms slightly away from the body. Style: stylized 3D game art at the standard of the best free-to-play hero shooters, bold readable silhouette, appealing face, stylized PBR materials, soft key light with a cool rim. No text, no logo.
    
    Show me both takes. Check each for the white chevron (which side, and how many), the glowing cyan braid tips, the silver hoops, the white knee guards, both blasters and the glowing wheels. Then wait for me to pick one.
  4. Make the three sheets from the approved hero

    The approved hero is the only reference for each sheet: adding the turnaround to the expression sheet turned every head three-quarter in the run. Give each reference one job.

    Prompt
    Keep take [A or B]. From now on it is the identity. Make three sheets with GPT Image 2.5 Sunburst (model_openai-gpt-image-2-5-sunburst), quality high, one image each, with referenceImages set to an array holding only the approved hero. Launch them with wait: false and collect them with one jobs_wait. Quote the cost with a dry run first and wait for my go.
    
    Sheet 1, the turnaround: width 2048, height 1152. Prompt, word for word:
    Character turnaround sheet of the character in the reference image. The reference image is the identity: keep her face, warm brown skin, long box braids tied high with glowing cyan tips, silver hoop earrings, cropped magenta bomber jacket with cyan piping and the white chevron on her right sleeve (viewer's left in the front view), black athletic top, fingerless gloves, charcoal tech leggings, white knee guards, roller blades with glowing cyan wheels and the two white pulse blasters holstered on her thighs exactly as shown. Four full-body views side by side in one row, same height, same scale, wheels on one shared ground line, evenly spaced, neutral A-pose with empty hands: front view, three-quarter view, left side profile, back view. Plain light warm-grey background, even studio light, no cast shadows, no text, no labels, no frames. Same stylized 3D game art rendering as the reference.
    
    Sheet 2, the expressions: width 1536, height 1024. Prompt, word for word:
    Expression sheet of the character in the reference image. Keep her face shape, warm brown skin, dark eyes, long box braids tied high with glowing cyan tips, silver hoop earrings and the collar of her magenta jacket. Six head-and-shoulders portraits in a 3 by 2 grid, every head turned straight to the viewer at the same size: neutral, big open smile, determined frown, surprised with raised eyebrows, worried, laughing with both eyes closed. Plain light warm-grey background, even light, generous space between portraits, no text, no numbers, no borders.
    
    Sheet 3, the outfits: width 1536, height 1024. Prompt, word for word:
    Outfit sheet of the character in the reference image. The reference image is the identity: keep her face, warm brown skin, long box braids tied high with glowing cyan tips, silver hoop earrings, body proportions and height exactly as shown. Three full-body front views side by side, same scale, feet on one shared ground line, neutral A-pose with empty hands. Left: her standard outfit exactly as in the reference, roller blades included. Middle: winter skin, a long padded teal parka with a fur-lined hood down, magenta knit gloves, white snow-camo leggings, the same roller blades with glowing cyan wheels. Right: off-duty skin, an oversized white hoodie with a magenta chevron, black joggers and white high-top sneakers instead of roller blades. Plain light warm-grey background, even light, no text, no labels. Same stylized 3D game art rendering as the reference.
    
    Check every sheet before you show it: every view shows the whole keep-list (chevron on the right sleeve, braid tips, earrings, knee guards, both blasters, glowing wheels); all figures in a sheet share one height and one ground line; the rendering matches the hero; every cell is what the prompt asked, head angle included. Redo a sheet once if it fails, and tell me what failed.
  5. Put her in scenes

    Hero first, turnaround second, in that order every time: the prompt calls them by number. Keep the first paragraph and swap only the scene paragraph for each new scene. For a scene in another outfit, swap the turnaround for the outfit sheet and name the outfit by its position.

    Prompt
    Make a scene with GPT Image 2.5 Sunburst (model_openai-gpt-image-2-5-sunburst): width 1536, height 1024, quality high, referenceImages [hero, turnaround] in that order. Quote the cost with a dry run first and wait for my go.
    
    Prompt, word for word:
    Reference 1 is the character's identity. Reference 2 is her approved turnaround sheet: use it for angles and for parts the first image does not show. Keep exactly: her face, warm brown skin, dark eyes, long box braids tied high with glowing cyan tips, silver hoop earrings, cropped magenta bomber jacket with cyan piping and the white chevron on her right sleeve, black athletic top, fingerless black gloves, charcoal tech leggings, white knee guards, two white pulse blasters holstered on her thighs, inline roller blades with glowing cyan wheels. Same stylized 3D game art rendering as reference 1.
    
    Scene: a busy salvage bazaar on a floating island at sunrise, stalls built from old hull plates under patched canvas awnings, crates of glowing batteries, a sea of clouds beyond the railing. She skates toward the camera down the middle aisle, holding a paper cup of noodles in her left hand, grinning. Medium-wide shot, full figure visible, camera at hip height, warm low sun from the right. No text, no signs with letters.
    
    Reject and tell me if the chevron flips sides, the face rounds or ages, the jacket changes color, an item is added or lost, or the style drifts toward photoreal or flat vector.
  6. Add a second character and stage them together

    Make the second hero with the first one as a style-only reference, then attach the cast in a fixed order and label every reference in the prompt. Changing the order silently changes what "Reference 3" means.

    Prompt
    Step 1. Make a second hero with GPT Image 2.5 Sunburst (model_openai-gpt-image-2-5-sunburst): width 1024, height 1536, quality high, numOutputs 2, referenceImages [Zuri's hero]. Prompt, word for word:
    Reference 1 is for STYLE ONLY: copy its stylized 3D game art rendering, stylized PBR materials, soft key light with a cool rim, plain light warm-grey background and full-body A-pose framing. Do not copy the person in it.
    
    New original character, full body, standing in a relaxed A-pose, three-quarter front view, feet fully visible, centered: Marlow Dune, a 50-year-old desert sniper hero. Tall and lean, a head taller than an average adult, weathered tanned skin, short grey stubble beard, calm half-smile, crow's feet. Wide-brimmed sand-colored hat with brass sun goggles pushed up on the brim, faded red bandana around the neck. Long patched sand-colored duster coat with patched pockets, worn to the knees, over a dark brown vest and a cream shirt, two crossed leather belts with ammo pouches, olive cargo trousers, scuffed brown lace-up boots. A long rail rifle with a cyan energy coil slung diagonally across his back, barrel up over his right shoulder. Empty hands, arms slightly away from the body. No text, no logo.
    
    Show me both takes and wait for me to pick one.
    
    Step 2. Make the two-character scene: width 1536, height 1024, quality high, referenceImages [Zuri's hero, Zuri's turnaround, Marlow's hero] in that order. Prompt, word for word:
    Two characters in one scene. References 1 and 2 are ZURI (identity and turnaround): 22, slim, warm brown skin, long box braids tied high with glowing cyan tips, silver hoop earrings, cropped magenta bomber jacket with cyan piping and a white chevron on her right sleeve, black athletic top, fingerless black gloves, charcoal tech leggings, white knee guards, two white pulse blasters holstered on her thighs, roller blades with glowing cyan wheels. Reference 3 is MARLOW: 50, tall and lean, a head taller than Zuri, weathered tanned skin, short grey stubble beard, wide-brimmed sand hat with brass goggles on the brim, faded red bandana, long patched sand duster over a dark brown vest and cream shirt, leather bandolier and belts, olive cargo trousers, brown lace-up boots, a rail rifle with a cyan coil slung on his back. Do not mix their features or clothes. Render both in the stylized 3D game art style of reference 1.
    
    Scene: the rusted edge of a floating salvage island at sunset, a sea of clouds and distant floating islands behind them. Marlow, on the left, hands Zuri a small glowing cyan power cell; Zuri, on the right, reaches for it with both hands, grinning. Both full body, medium-wide shot, camera at chest height, warm sunset light from behind with a soft cool rim light. No text.
    
    Accept only if each character carries only his or her own items, Marlow is about a head taller, left and right match the prompt and both are full body. Quote the cost with a dry run first and wait for my go.
  7. File the identity pack and report

    The collection is the identity pack every later scene attaches.

    Prompt
    Create a collection called "Zuri Vex" and add the approved hero and the three sheets to it; put the identity paragraph in its description. Create a collection called "Marlow Dune" with his approved hero, and add the kept scenes to both. Report the model, every asset ID with what it is, and the total cost spent.
