Hi,

Sorry not to mention the input images. Its about 26 overlapping 16MP images, no HDR or stacking involved. This was shot with a decent flat field 300mm prime, so they have very little distortion for Hug in to undo. For the overlapping control points, the fit is great, about 1 pixel delta. Seams look great on the rendered image. About 30% overlap between shots. Very few vertical / horizontal lines were detected. I tried to improve matters by adding a 2 or 3 per image. On checking each of them, they all look perfect. This had the effect of changing the shearing from vertical to horizontal.

OK. If your input images and process is pretty much the same as for your other successful projects, it is difficult to guess at what might be going wrong. Have you tried correcting/stitching a few at a time, save in equirectangular, then stitch the resulting tiles? It is a more drawn out process, but may also allow you to see where the problem is occurring. You could also get all your control points, added horiz and verticals, and then try adding one image at a time to the optimization, to see if that isolates the problem.

Cheers,
