Region fix: change one part, keep the rest

Region fix regenerates only the part of your book cover art you brush over (or describe) — the rest of the scene stays untouched.

Most AI covers fail in one square inch, not everywhere: a hand with six fingers, a lighthouse window in the wrong place, a smear that looks like lettering. Re-rolling the whole prompt throws away the ninety percent that worked. Region fix asks the model to repaint one area and leaves the rest of the pixels exactly as they were.

Your title never enters this operation. Typography in Veritas stays live vector type on a layer above the art, so a region fix can never blur, warp or re-spell your book title.

How to use it

1. Put the art on the canvas
   Open the studio with art already on the canvas — generated from a brief, dropped in from your own file, or restored from an earlier session. Region fix always works on what is currently on the canvas.
2. Open the Region fix scene
   In the AI hub, choose Region fix from the left rail. The current cover art loads into the INPUT column as the source image.
3. Mark the area
   Brush over the part you want regenerated, or skip the brush and describe the area in words — a bad hand, the sky above the horizon, the sign on the door. The masked area is the only region the model is allowed to change.
4. Describe the replacement
   Write what should be there instead, in plain language: "a closed wooden door, no handle", "clean night sky, no birds". Keep the sentence about the region, not about the whole cover.
5. Run it and place the result
   The operation costs one credit and returns a proof in the RESULT column. Compare it against the original, then place it on the canvas — your typography layer is untouched and still editable.

What it solves

A hand that came out wrong on a romantasy cover

Character-led romantasy art is the classic case: the composition, the dress, the light are all right, and one hand has an extra finger. Brush the hand, describe it plainly ("a relaxed hand resting on the railing, five fingers"), and the rest of the illustration — including the face you liked — stays byte-for-byte the same.

Ghost lettering the model invented

Image models paint letter-shaped noise because almost every cover they trained on carried a title. If a fake word appears on a spine, a sign or a banner, brush it and ask for the surface without text. This is usually faster and cleaner than a re-roll, because the surrounding texture is preserved rather than reinvented.

A thriller cover with too much noise near the title zone

Your title needs a quiet third. If the top of the frame is busy, brush that band and ask for empty sky, fog or a flat wall. You are not moving the title — you are clearing the area under it, so the vector type stays crisp at Amazon thumbnail size.

Frequently asked questions

Do I have to brush the area, or can I just describe it?

Either works. A brushed mask is exact and best for small repairs like hands or logos; a written description is faster for large obvious regions such as "the sky" or "the background wall". When both are given, the brushed mask wins and the description tells the model what to paint inside it.

Will region fix change my title or author name?

No. Titles and author names are live vector type on a layer above the art, and AI operations only ever touch the art layer. That is why your text stays razor-sharp in print while the artwork underneath can be edited freely.

How is this different from re-running the brief?

A new brief is a new image: new composition, new light, new everything. Region fix keeps the image you already approved and repaints one area. Rule of thumb — fix at the edges and in details, regenerate when the whole idea is wrong.
