Title:
Include mask and MOST of 2nd image black
Status in Enblend:
New
Bug description:
I have a 2-image pano that has a car in the overlapping section of the
left image, and none in the overlapping section of the right one.
I want the car to be there.
Despite the car being there in the preview, it is missing in the final pano.
Thinking that Hugin is automatically preferring the right over the left, I "cleverly" flipped both
images so that the car was in the right image, and ran Hugin again. Car still missing...
I researched the problem, and came upon the concept of Masks, and how
to make an include mask.
I drew a polygon around the car, selected "Include Region", and then "Stitch!" (or possibly
"3. Create panorama").
The area of the mask is completely black on the left part of the final image.
The right part of the image is also completely black, except for a thin horizontal strip along
the top, which blends into the black.
In searching for others who might have reported this bug, I came upon:
https://answers.launchpad.net/hugin/+question/675074
which suggests: "- add switch --primary-seam-generator=nft to the enblend options on the stitcher tab"
Indeed, this solves the problem.
However, the bug has not been fixed, even though it must have existed
before "2018-10-11", as the very first comment contained the above
suggestion.
The same comment said: "Either the remapping stage has a bug or the blending program has problems in finding the correct seams for complex masks."
There are only two images, and one mask, in my image - not "complex", then...
Is there no way for Hugin/enblend to recognize the problem, and apply
the solution automatically?
Perhaps if an include mask is present, that should be enough to
trigger it...

I will attach the .pto file, and the final image.
If you want the original .jpg s let me know.
[I have checked the "copy logfile to clipboard" preference, but I get nothing
upon "pasting" into my text editor - maybe because of Wayland (but I normally
have no problem with ctrl-c/ctrl-v cutting and pasting) ... ]
