I use 2022. I've rarely gotten it. It only seems to happen when I'm messing 
around with complex masks, or it turns out that alignment is really off.

"Me too".  This seems to be happening more frequently.  Until recently
I was using the 2018 version, then 2022, and with 2022 things became
worse.

I'm still investigating, and so far I don't have any further
information, but at least I wanted to say that you're not alone.
Hopefully I'll come up with more information.

The FreeBSD port has been updated to this version.  Update your source
tree and build /usr/ports/graphics/hugin.  It will take a little
longer for the package to become available.

Re: [hugin-ptx] Stitch Panorama Without Blending Exposure?

2023-11-12 Thread Alexander Drecun
Those are all good suggestions! I've edited the control points quite a bit
to get the goldilocks level of mismatching - not too much, not too little -
to the point where I'm very happy with the result, but I'm still not having
any luck getting a stitch in the manner I'm after. I'll try the remapped
image option next. Is there no way to turn off enblend/enfuse?
