Choose one connected space
Start with a single room or an open area you can photograph continuously. Do not combine a hotel bedroom, lobby and garden into one source set. The model needs enough shared features to relate the views.
Roam accepts 1–20 photos, but the maximum is not a target. Four to eight useful, overlapping views are a practical starting point. More unrelated photos can create more ambiguity rather than more detail.
Photograph around the room
Stand inside the space and capture adjacent views with visible overlap. Keep corners, windows or furniture in successive photos so their relationship is clear. Include a view back toward your starting point.
Use steady, sharp images. Keep the phone roughly level, use consistent lighting and avoid heavy filters. Do not move furniture between shots. A panorama can also give a broad account of the room; our Big Little Boxes example includes the original panorama for comparison.
Use a genuine 360° panorama on its own
A true equirectangular panorama is exactly twice as wide as it is tall and includes the complete view around, above and below the camera. Its left and right edges should join. A 360 camera or an existing authorized spherical capture is a useful starting point.
Upload one panorama by itself. Do not mix it with regular photos, other panoramas or video. A phone’s narrow panoramic strip lacks full vertical coverage; stretching or cropping it to 2:1 does not supply the missing scene. A better reference reduces guessing but does not guarantee an exact reconstruction.
Check the files before uploading
Upload photos or one video, not a mixture in the same generation. Export unsupported phone formats as JPEG before upload. For a video, use a continuous walkthrough no longer than 60 seconds and keep the movement slow enough for details to remain visible.
- Remove blurry frames and near-duplicate photos.
- Exclude unrelated rooms or photographs from other locations.
- Check for faces, private screens and personal paperwork.
- Keep the originals so you can compare them with the result.
Use the draft as a decision point
Compare the generated room with your source material. Look at the number and position of doors and windows, the main furniture and the path through the room. AI can invent details, including text and objects it cannot see clearly.
If the draft gets the room wrong, try a more coherent source set. HD is a new generation at a different quality tier; it is not a guarantee that an incorrect layout will become accurate. Approve the result before putting it in front of customers.
