What photo does Roadster AI accept?
One photo, and it has to show the whole subject. A car, a truck, or another vehicle is the closest match, because the source body is a car. Another object is allowed. For a sofa, sculpture, or product, the instruction asks to retain its own form without adding headlights, wheels, or a grille. Inspect the output to confirm that this instruction was followed. It still has to read as itself while it follows a car path, so that result needs a stricter look. Show the silhouette, the color, and one detail you can still recognize when the subject is small, such as a roof rack or a contrasting roof. A badge crop leaves the body to be invented. Two vehicles in one frame make the subject ambiguous. A person standing beside the object can be read as part of it, so frame the object on its own. The page has one subject slot. A different subject means a new photo in that slot.
