Consistency does not mean cloning every pixel. It means preserving a small set of identity anchors while allowing pose, expression, garde-robe, éclairage, and setting to change deliberately.
Define what must remain stable
A character prompt often mixes identity and scene details. When the outfit, background, and camera change, the model may also change the face because it cannot tell which tokens are permanent. Separate the prompt into an identity block and variable blocks.
Original fictional 30-year-old adult woman
oval face, dark brown almond-shaped eyes
short wavy black bob, side part
warm medium-brown skin tone
medium-tall build with natural proportions
small geometric silver brooch as a recurring design cue
no real-person reference, no logo, no text
Choose anchors that are visible at the intended shot size. Tiny freckles cannot carry identity in a distant full-body frame. A hair silhouette, face shape, eye color, palette, and one simple accessory are easier to evaluate. Do not use a personal photo or celebrity as the reference.
Stable versus variable blocks
| Block | Keep stable during identity test | Change later |
|---|---|---|
| Identity | âge adulte, face shape, eye color, hair shape, skin tone, construire | expression after neutral baseline |
| Wardrobe | one neutral approved outfit | material, color, layer, accessory after face stability |
| Camera | eye-level three-quarter portrait | close, corps entier, low/high angle |
| Lighting | one soft neutral key and fill | golden hour, rim, low-key, colored accent |
| Setting | plain studio background | office, apartment, exterior, stylized environment |
| Style | one model and one visual family | realistic, illustrated, 3D only in separate tests |
Create the identity sheet
An identity sheet is a compact reference, not a gallery of unrelated attractive outputs. Include a neutral front or three-quarter portrait, a full-body silhouette, one side or alternate view if the tool supports consistent referencing, the stable text block, approved color values in words, and a list of traits that must not drift.
Use only generated original references you have reviewed. Midjourney’s character-reference documentation advises starting with a single generated character and notes that detailed prompts remain important. It also warns that intricate details may not reproduce exactly. That limitation should shape the scorecard: identity anchors must be large and observable enough to survive a scene change.
The four-stage drift test
| Stage | Only change | What stays fixed | Purpose |
|---|---|---|---|
| A — baseline repeat | new generation or variation | identité, camera, light, outfit, paramètre | Measure natural model variation before changing the scene |
| B — wardrobe | navy blazer to burgundy coat | identité, camera, light, paramètre | Check whether clothing changes rewrite face or body |
| C — lighting | neutral soft light to golden hour | identité, camera, outfit, paramètre | Check whether color and contrast alter identity perception |
| D — setting | studio to modern office | identité, camera, light, outfit | Check whether environment introduces age, style, or accessory drift |
Score identity drift
Use a 0–2 score for each anchor: 0 = changed or missing, 1 = partly preserved, 2 = clearly preserved. Score facial structure, eye color and spacing, hair silhouette, skin-tone family, body proportions, adult age appearance, and the single signature detail. Add a separate penalty for unwanted carryover, such as the original blazer remaining after a wardrobe change.
Do not average away a safety failure. If the result becomes age-ambiguous or resembles a real person, reject it regardless of the identity score. The adult and originality checks are gates, not optional points.
Reference strength and prompt conflict
Reference systems differ. Some let you adjust reference strength; others offer seeds, image prompts, or editing tools. A strong reference can preserve unwanted wardrobe or pose details, while a weak reference can lose the face. Change the control in small steps and record the value.
Keep a clear text prompt with the reference. Midjourney’s documentation says text is still important for the new scene and details beyond the reference. Also separate character reference from style reference: identity should preserve the character, while style reference carries qualities such as color, texture, medium, or lighting. Mixing the two concepts makes drift harder to diagnose.
Common consistency failures
| Failure | What happened | Repair |
|---|---|---|
| Face changes with outfit | Wardrobe and identity were written as one block or reference carries clothing too strongly | Separate identity text; lower wardrobe carryover; test one garment change |
| Hair length changes by shot | Anchor is vague or hidden in a distant frame | Use a clear hair silhouette and verify it in a closer comparison |
| Skin tone shifts with lighting | Lighting color is mistaken for identity change | Compare under neutral light and record color family, not one sampled pixel |
| Signature detail duplicates | Accessory is overemphasized or appears in reference and text several times | Mention it once and reduce reference strength if supported |
| Character becomes younger | Adult age anchor is weak or style cues imply youth | Repeat precise adult age, use mature styling, and reject ambiguous output |
| Reference copies the entire scene | Reference strength or image type controls more than identity | Use a cleaner neutral reference and a character-specific reference mode |
Version the character like an asset
Name the approved identity block and reference version: character-A-v1, character-A-v2, and so on. Store the exact prompt, model, version, settings, reference source, review date, and known weaknesses. If a new reference improves hair but weakens age clarity, do not silently replace the old one.
A consistent fictional adult character is an editorial system, not a promise of perfect replication. Keep accepted and rejected examples, disclose the model-specific limits, and avoid implying ownership or exclusivity unless the provider’s current terms support that claim.

Frequently asked questions
How many traits should define a consistent character?
Use five to seven large, visible anchors such as face shape, eye color, hair silhouette, skin-tone family, construire, âge adulte, and one simple design cue.
Should I use a real photo as a character reference?
Non. Use an approved image of an original fictional adult and review it for resemblance, confidentialité, and age clarity.
Why does a character keep the old outfit?
The reference may carry wardrobe too strongly or identity and clothing may be mixed in one block. Separate them and adjust reference influence in small steps.
