      Did you by chance resize the image in photoshop while it was still
      layered? This would be the culprit. First flatten your image, then
      resize. Ah, and did you check it is exactly 2:1 ratio? Not f.e. 8000x3999?

      Another cause once happened to me and cost me three days of work: If you
      shift-drag images in photoshop and you release the shift key too soon,
      the layer will not be placed exactly...

      Try changing the initial view when the panorama opens and see if that will make it go away. I ran into that same problem with QTVRs and it solved the problem

        Thanks, everybody, for the suggestions... I didn t resize the image at any point- I set the output from PTGui to 6000 X3000, and kept it that size throughout.

          I didn't resize the image at any point- I set the output from PTGui to 6000 X3000, and kept it that size throughout. I don't think I saved to .tifs or .jpgs with layers- PS warns you that the file size will be bigger if you do that, so I always go back and flatten- but I might have missed that.

          Picking up on Ned's suggestion, I found a workaround. Since the line was at the point where the image wrapped, I went back to CC and changed the initial view, then generated new cube faces. The line appeared in the bottom, back and top faces, so I cloned it out in each face, and reassembled the equirectangular image.

          Now that the WWP submission is in, I'm going to go back and start from scratch and see if I can fine out what happened- I'll post the results here.

          Again, thanks for the help.

          Jpegs don t have layers, so you won t get that warning. Autoblending can also cause the line. Sacha Griffin Southern Digital Solutions LLC

              I had the same experience as Erik. I have also had a noticeable difference at the seam that is created when the two ends of the equirect join in the final product. That time the problem was caused by filter use on one of the layers. If you utilize the offset filter in PS, you can see if there will be a problem with the seams before you convert into flash, java or qtvr file.

              Apart from the other suggestions, I ve had this occur in the past when sharpening a cubic (using Ultra-sharpen pro) before converting to the final equilateral.

                  Hi,

                  The best stage to sharpen panos is the initial fisheye images, before they are stitched.

                  Actually, sharpening cube faces is the next best option.

                  The worst option is to sharpen the final equirect. when you do, you'll get some weird stuff at the zenith / nadir. I know it's the easiest way (and i've sharpened many panos at this stage) but it is not the optimum time to do your sharpening of panos.

                  If you must sharpen the final equirect, you could consider not sharpening the zenith/nadir portions of the image.
