Comment 2 for bug 843742

Hi Martin
Thank you very much for this report. However, this bug is a duplicate of bug #720556 (https://bugs.launchpad.net/hugin/+bug/720556).
It is caused by two identical images (at least hugin/enblend thinks so). In such a case, enblend aborts (rightly) with the error message
enblend: warning: failed to detect any seam
enblend: mask is entirely black, but white image was not identified as redundant
If the images actually are identical, you can remove it from your project.
However, in most cases one of the images does not have any control point assigned and therefore gets the same position as the anchor image. So please check if all images actually have several control points in your projects.

Regards

Stefan Peter
