How to keep a character consistent across AI images

To keep a character recognizable across AI images, define a small set of stable visual traits, approve a clear reference and reuse it as a reference image in Deepnia Image. Change the scene without casually rewriting the character. Compare every result with the approved reference.

To produce the whole series at once, choose Seedream v5.0 Lite Sequential in Deepnia Image: it generates 1 to 15 consistent images.

A useful series needs more than a similar face. Hair, clothing, proportions and illustration style also affect whether readers perceive the same character. The example below follows a fictional illustrator through three scenes to show how to plan those decisions before generating a full sequence.

Define what must stay consistent

Separate identity from scene-specific details. Identity includes the features that make the character recognizable: face shape, hairstyle, overall build and distinctive accessories. Scene details include the action, location, pose and props. Clothing may belong in either category depending on the story.

For a campaign happening on one afternoon, the same jacket may be a continuity requirement. For a story spanning several days, clothing changes can be intentional. Decide which rule applies instead of treating every variation as a mistake or accepting every difference without review.

Also define the visual treatment. A character rendered as a flat drawing in one scene and a photographic portrait in another may feel inconsistent even if the hairstyle matches. Keep the medium, palette and level of detail stable unless a deliberate style change serves the project.

Build a short character sheet

Create a written description that is specific enough to inspect but short enough to reuse. Avoid dozens of minor details that will be difficult to maintain and irrelevant at the final display size. Prioritize a few recognizable features over decorative complexity.

Here is an original fictional character sheet for a planning exercise:

• Character: an adult illustrator with a rounded face and short curly dark hair.
• Clothing: a mustard overshirt over a plain cream top, with dark trousers.
• Distinctive item: round dark-framed glasses.
• Treatment: warm editorial illustration with simple shapes and soft texture.
• Stable palette: mustard, cream, dark blue and warm brown.
• Flexible details: pose, expression, workspace and handheld objects.

The purpose is not to encode a person perfectly in text. It is to make your intentions explicit and give you a checklist. If the glasses or overshirt matter to recognition, you will know to inspect them in every scene.

Approve a reference before producing the series

Start with a clear view of the character in a simple setting. Avoid a reference where the face is hidden, the clothing is obscured or dramatic lighting changes the apparent colors. You need something that communicates the traits you want to preserve.

Inspect this reference before treating it as approved. Fix unwanted anatomy, clothing details or accessories at this stage. Otherwise, you may spend the rest of the series trying to preserve a design that was never right in the first place. Once approved, this reference can anchor a whole series in Seedream v5.0 Lite Sequential, which accepts up to 10 reference images.

Keep the approved file separate from experiments. If additional views are necessary, compare them with the same design rather than assuming they automatically match. A collection of inconsistent reference images can introduce ambiguity instead of solving it. For your own face, Face Studio creates consistent portraits from a selfie.

Use reference images in Deepnia Image

Open Deepnia Image and add your approved reference; you can also edit an existing image instead of starting over.

A style reference and a character reference are not the same requirement. One concerns visual treatment; the other concerns the recurring subject. When you add several inputs, explain their roles clearly.

Start with one controlled scene

Before generating a complete story, test one scene in Deepnia Image using your approved reference and character sheet. A small consistency test is more informative than generating many scenes before discovering that a key feature keeps changing.

Keep the character brief stable while changing the scene

Split the prompt into two parts: the recurring character and the current action. Reuse the stable description, then add only the scene-specific instructions. This makes it easier to identify whether a mismatch came from the reference, the character description or an ambitious new composition.

Example prompt for the illustrator’s first scene:

Use the supplied approved character reference. Keep the rounded face, short curly dark hair, round dark-framed glasses and mustard overshirt over a cream top. Maintain the warm editorial illustration treatment. Show the character seated at a simple desk, arranging three blank paper cards. Use a medium view with the face clearly visible. Do not add lettering or new accessories.

For scene two, replace the action with “standing beside a noticeboard and pointing to a blank card.” For scene three, use “reviewing an open sketchbook at the same desk.” Keep the identity and style instructions unchanged unless the story genuinely calls for a change.

Review the images together, not only individually

A single picture can look convincing while failing as part of a sequence. Place the scenes side by side at a similar size. First ask whether you immediately recognize the same character without relying only on the clothing color.

Then check the face shape, hair silhouette, glasses and body proportions. Examine the overshirt’s basic design and the relationship between the cream top and jacket. Look for changes in sleeve length, collar shape or accessories that were not part of the brief.

Finally, compare the visual treatment. One scene may have much stronger texture, sharper shadows or a different palette. These differences can make the series feel assembled from unrelated projects. Keep a short note for each scene: identity accepted, clothing correction needed, style too different, or ready for layout.

Correct drift without changing the whole scene

Suppose the noticeboard scene works but the glasses have become rectangular. In Deepnia Image, edit that scene and ask only for that correction while preserving the accepted pose, layout and treatment. If the face has changed substantially, return to the approved reference rather than treating the drifting output as the new standard.

Avoid using each new scene as the only reference for the next. Small differences can accumulate through a chain of revisions. Keep comparing to the original approved design and track intentional changes separately from accidental ones.

Some compositions will be harder to maintain than others. A distant full-body view, an extreme angle or a partially hidden face may make the character less recognizable. If the exact composition is not essential, choose a clearer view rather than spending repeated attempts on an unnecessary difficulty.

Organize the accepted sequence

Save the reference, character sheet and approved scene files together. Use filenames that identify the scene and version, such as “illustrator-noticeboard-approved.” Keep rejected experiments separate so a later collaborator does not accidentally use a mismatched image.

Review the sequence in the actual final layout. The same character may look consistent at full size but become hard to identify in small cards. Crop carefully and preserve the features that carry recognition. If one scene needs a closer crop, check that it still fits the story.

Frequently asked questions

Is repeating the same name enough?

No. A fictional name does not necessarily communicate a stable appearance to the model. Reuse a clear visual description and add your approved reference image in Deepnia Image, or generate the series at once with Seedream v5.0 Lite Sequential.

Can the character change clothes?

Yes, when that is intentional, but define which identity traits must remain stable. Review the result without relying on the old outfit to establish recognition. Keep costume changes documented so they are not confused with errors.

How do I generate several images of the same character at once?

Use Seedream v5.0 Lite Sequential: it generates a series of 1–15 consistent images from one request.

Build the series from an approved design

Start with a character sheet and one accepted reference, then open Deepnia Image and test a simple scene. Use the prompt-writing guide to separate stable traits from scene instructions, and the targeted correction guide when only one detail needs attention. To animate the series, open Deepnia Video with Gemini Omni, or follow the guide to turn a short story into an AI video.
