Questions before the first photograph is edited
What a single room redesign keeps, and when a second photograph is worth adding.
Can I redesign from a single photograph?+
Yes. The first photograph is the room that changes. Add a hall or a bedroom only when you want to see whether the same wood, cloth, and metal still read as one interior.
Do the rooms have to match piece for piece?+
No. A bedroom does not have to inherit the living room sofa. It does have to be able to show the same wood, the same cloth, and the same metal if you named them.
What if the hall is tile and the living room is oak?+
Lock the floor on the view that must keep it, or name the change as part of the direction. An extra stone that neither photograph asked for does not belong.
Will the windows move to make the rooms match?+
No. Each photograph keeps its own openings and its own camera. Likeness comes from the materials, not from redrawing the shell.
How many photographs are useful?+
One is enough to redesign a room. Two can test a direction: the room you care about, and the space you pass through to reach it. A third, often a bedroom, makes a false material obvious.
What does a generated view keep?+
Walls, windows, doors, and the camera stay. Floor, furniture, built-ins, and clutter stay only when you lock them. The first photograph is the view that is edited.
