What is Inpainting?
Regenerating only a masked (brushed) region of an image while everything outside the mask stays pixel-identical. Used to remove cars or people, swap a sofa, or change one wall finish without redoing the whole render.

Inpainting is selective regeneration. You brush over a region of an image, describe what should appear there, and the model redraws only that area. Everything outside the mask is left identical, so the rest of an approved image does not change.
Why it matters
Renders rarely come out perfect in every corner. A parked car ruins an entrance, a chair is the wrong style, or one wall needs a different finish. Rerunning the entire image risks losing the parts that already work. Inpainting fixes one thing at a time and keeps the approved result stable.
Example
In a living-room render, the designer brushes over the sofa and asks for "green velvet sofa". Only the sofa changes; the windows, floor, lighting and camera stay exactly as they were. The same method removes cars, signs or people from an exterior photo.
Common mistake
Painting a mask that is too tight. Leave a small margin around the object so shadows and reflections can update with it. Another mistake is changing too much at once; do small edits one after another for cleaner results.
Practical tips
Work in small steps: one mask, one change, then check. Describe only what should appear inside the mask, such as "pale oak dining table", rather than repeating the whole scene. For object removal, ask for the surface that should be there, for example "clean paving" or "plain wall". If an edit looks pasted on, enlarge the mask slightly so the surrounding light can blend.
