My project contains one or more images without any recognizable detail and its impossible to place control points. How can I stitch my panorama?
Sometimes one or more images in a panorama don’t show any suitable objects to place control points on, for example when an image contains only blue sky or a plain white wall. Since the exact alignment of a plain colored image is usually not critical, you can align it by hand: First make sure that the rest of the panorama is set up properly (usually just pressing Align Images is enough). Then go to the Panorama Editor window by pressing Ctrl+E (Windows) or Command+E (Mac). Switch the panorama editor to ‘Edit Individual Images’ mode using the toolbar, the menu or by pressing Ctrl+Shift+I (Windows) or Command+Shift+I (Mac). In this mode you can move individual images around. Use the left mouse button to move an image, or use the right mouse button to rotate it. Single button Mac users can use Ctrl+Mouse button to rotate. For more information see the Help page for the panorama editor pressing F1 (Windows) or Fn+F1 (Mac). When done, go back to the main window, click on Optimize and proceed
