Refine

Fix one part of a version with the brush

Refine fixes one part of a version without starting over. You paint over what came out wrong, say what it should be, and only the painted part is regenerated; the rest of the result stays as it was.

What it does

Most versions are nearly right. A lamp lands in the wrong place, a baseboard comes back the wrong color, a reflection in the window doesn't make sense. Refine is for exactly that: you brush over the part you want redone instead of generating the whole room again and losing the parts you liked.

The brush works like a highlighter over the result. Paint the area, adjust the brush size for tight corners, erase if you went too far, and write what the painted part should be. Everything you didn't paint stays as it was.

Refining a version doesn't replace it. The new one joins your history beside it, so you can go back to the one you started from at any time.

The drawing at the top of this page is the brush at work: the painted band is the part that gets redone, the ring is the brush's size, and everything outside it stays as it was.

How to use it

  1. Open the version you want to fix

    Refine works on a result, not on the original photo. Open the version from your history first.

  2. Paint over the part that's wrong

    Switch to the Refine brush and paint. Make the brush smaller for a tight corner, larger for a whole wall, and erase anything you overshot.

  3. Say what it should be

    Write the note for the painted part the way you would for an area: the color, the material or the piece you expected to see there.

  4. Generate the fix

    Only the painted part is regenerated. The new version joins your history next to the one it came from.

What it can't do

Worth knowing before you spend a credit on it.

  • Refine redoes what you painted. It can't move something from one side of the room to the other.
  • A painted area that is too small gives the model very little to work with. Cover the whole object, plus a little of what surrounds it.
  • Each Refine is a new version, and costs what any version costs. There's no free fixing.
  • Repeated Refines of the same spot can soften it. If three attempts haven't worked, change the note rather than the brush.

Questions about Refine

What's the difference between Refine and marking an area?

Marking works on your original photo and starts a new change. Refine works on a version you already have and redoes only the part you paint, keeping the rest of that result.

Does Refine change the whole image quality?

No. The painted part is regenerated and blended into the version you started from; everything outside it stays as it was.

Can I refine a refined version?

Yes. Each version can be refined again, and each one is kept, so you can always go back to the version before the fix.

What if I paint too much?

Erase it. The eraser takes paint off before you generate, and nothing is charged until you do.
