AI scene generation for interactive stories

A useful scene image helps the player read a place, a character, or a change in mood. Before generating variations, decide which details must stay the same across the story and which details should change in this particular scene.

A reference brief gives you something concrete to check against. It improves direction, but it does not guarantee that every generated image will match; review recurring details in the actual story preview.

1. Separate fixed details from scene changes

For a recurring character, record a short set of recognizable traits: silhouette, hair, clothing, and a distinctive accessory. Keep personality and speaking style in the story brief. For a location, record its layout, a few landmarks, and the normal lighting. Then describe the expression, pose, or time of day that changes in the current scene.

• Fixed character details: Mina, an adult archivist; short black hair, round glasses, navy cardigan, brass key on a cord.
• Fixed location details: narrow archive aisle; green reading lamp on the left, tall oak shelves, a window at the far end.
• Scene change: Mina has just recognized the handwriting. Her expression is restrained surprise; it is still before dawn.

These are invented example details, not a required style. Replace them with details that matter to your own story.

2. Write one visual brief you can reuse

“Use a softly shaded illustration style with muted blue and warm amber light. Keep Mina's short black hair, round glasses, navy cardigan, and brass key visible where the framing allows. The archive has tall oak shelves and a green reading lamp. In this scene, Mina studies a sealed letter with restrained surprise. Leave a quiet area in the lower part of the frame so the dialogue remains easy to read.”

The brief asks for a visual target; it is not a promise of exact placement or text-safe composition. Check the result with the story's dialogue box on screen and adjust the framing if needed.

3. Check the image in context

Review a recurring character across adjacent scenes instead of approving each image in isolation. A good standalone image may still confuse the story if a coat changes color, a room reverses its layout, or the mood becomes cheerful during a tense exchange.

• Can the player recognize the same character at a glance?
• Do clothing, props, and lighting match the point in the story?
• Does the pose or expression support the current line of dialogue?
• Is the important part of the image visible behind the interface?
• Is the image readable at a phone's screen size?

4. Revise one problem at a time

Prefer “Keep the outfit and lighting; make the expression less cheerful” to “Make it better.” Change the brief when the direction is wrong; revise the image when the direction is right but a detail is off. Keep a usable version before trying a variation, and review the new result before replacing other scenes.

Generate extra expressions or location variants only when a scene needs them. Fewer well-chosen assets make continuity easier to check and reduce unnecessary generation. Once the route and dialogue work, polish the visuals that carry the most important moments.
