Refine a Panel Without Redrawing the Page

TL;DR. Open Refine on a panel that already has an image. Describe the change — a night background, a surprised face, heavier rain, a shorter line. Submit. The new image joins that panel’s history, and you can restore the previous take.

Start from an existing imageRefine needs the current panel picture. If the frame is still empty, generate or upload one first.

Write one changeThe instruction is plain language: make the background night, push the expression to surprise, strengthen the rain, adjust the pose. The first-run coachmark points at the three usual jobs: line, expression, pose or framing.

Generate the revisionSubmit queues a refine job that uses the current image as reference. Wait for it to finish. A failure toast means the job did not land; the previous image is still current.

Keep or restoreThe new picture becomes current and the old one stays in history, marked as a refine. Restore history if the instruction overshot. Restoring does not charge again.

When refine is the right tool

Use refine when the panel is almost the page you wanted. The face is close, the staging is close, and one instruction can move it. Use a full regenerate when the prompt itself was wrong. Use Sketch when the layout of the page is wrong. Use Infinite Canvas when one region of a still — a hand, a sign, the eyes — should change and the rest of the pixels should stay.

Instructions that tend to land

Name the change and the thing that must stay: “night sky, same coat, same two people.”
One emotion or one pose is easier than a new plot beat.
If the line of dialogue is baked into the image, say what the new line should read.
If refine keeps drifting the face, go back to the character reference and regenerate the panel from the prompt instead.

Refine spends a generation. The exact credit cost follows the painting model in use. History is free to restore.
