- In the editor, switch to “Toutes les options” (all options), “Relier les espaces” step (link the spaces), and choose the space.
- In the space’s settings, open “Retoucher la photo” (edit the photo), then “Redresser l’horizon” (straighten the horizon). A grid appears on the photo.
- “Face à vous” (in front of you): drag (or tap − and +) until the walls and doors follow the lines of the grid.
- “Sur le côté” (to the side): the view turns a quarter turn; adjust the same way.
- “Enregistrer la photo redressée” (save the straightened photo). The arrows and the arrival view follow; the public sees the straight photo after “Mettre à jour la visite” (update the tour).
Right after saving, “Annuler” (undo) brings back the original photo: it is never deleted.
