Change the [target, e.g. front door of the blue house in the center] to [new state, e.g. a glossy door painted #C0392B with a brass knocker]. Keep the house, windows, plants, lighting and camera angle exactly the same.

Replace everything in [square brackets] with your own details.

Settings & parameters

• Model: FLUX 3 Image with one image in images
• Use box rows (0–1000 grid) when several similar objects match, or to move/resize/remove one element

Variations

• Replace: "Replace the coffee cup on the right with a glass of orange juice."
• Text: "Change the sign text to 'OPEN DAILY', same font and color."
• Remove: "Remove the scooter by the curb and fill the street naturally."

Tips

• Pick the target so only one thing matches (position, color, neighbor).
• Name the detail to preserve when it matters ("keep her pose").
