Yes View seems like it would be also covered by the position if using the same > camera for all images.

Note also that you are assembling your images into a plane, so you need to set the output projection to rectilinear, not equirectangular. -- Bruno -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
