Hi, and thank you for your reply: I'm afraid I have to say I already use rectilinear pictures... the example i posted before uses 32 images (actually 96 images, 3 exposures for each position) 3x10+zenith+nadir, and they are near perfect Manual placement at this point is not a deal breaker for me: it's just that i would like to reflect changes in the positions of images into the Hugin project, or the modifications to my workflow would be too heavy: that's why simply aligning in GIMP is not ok for me :(
