Lightroom Classic: Panorama Stiching - Photo Merge Error, unable to merge the photos

Hello,

after a couple of years away from photo editing, I am back and discovering the latest version of Lightroom classic, the 9.1. Last version I used was version 6.

I am bumping into an issue with Lightroom classic 9.1 and don't understand what is happening and how to solve the issue.

Basically whenever in a new catalog I am trying to merge a few pictures together as a panorama, Lightroom will be able to render the preview, but then it will drop me an error message after a while when I carry on to merging the panorama.




It doesn't depend on the number of pictures. it gave me the error with 2 pictures as well as with 16...

I was able to flawlessly stich 16 vertical pics panoramas in Lightroom 6...

I opened one of my old Lightroom 6 catalogs and was able to successfully merge several 10+ RAW files panoramas. It seems like the issue is only in new Catalogs that I create.

I shared the RAW files that are failing with other people, and they were able to successfully merge the panoramas where I am failing.

I completely uninstalled LR 9.1, didn't keep the settings, deleted all the Lightroom related folders from the system, and re-installed LR Classic version 9.1. Issue is persisting...

Here are some infos from my LR config :

Me,

Try resetting your preference file:

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

Reset Procedure:
1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.Does the behavior continue after resetting the preferences?

Is there a way I could back up my preferences before doing this ? Like I said in my post, I am pretty sure I already reset my preferences when uninstalling Lightroom and deleting all the Lightroom folders in program files\adobe and in Appdata\roaming and local.
I spent some time setting everything back again, so I'd like to back settings up before doing what you suggested, just in case :)

Thanks in advance

Yes, the manual option here will work: How do I reset Lightroom’s Preferences?

Hi Rikk, Hi Victoria,
I renamed my "Lightroom Classic CC 7 Preferences.agprefs" preference file instead of getting it deleted, it rebuild a new one and sadly the behavior is still there.
Tried to create a new catalog and import new RAW files I recently shot, and the result is still the same :(
"unable to merge the photos" exactly as in the screenshot of my 1st post.

Heeeeeelp, this is a brand new computer with a fresh install of windows and lightroom...

I actually just tried to stitch a panorama with horizontal photos instead of vertical ones, and it worked. Looks like the issue occurs with panoramas based on vertical frames ?

Will have to experiment a bit more to confirm this 100%

Hello, are you trying to stitch vertical images (shot in portrait mode) into a horizontal or a vertical image?

I'm getting the same problem. So frustrating. 
Even photoshop is unable to stitch. The preview generated on Lightroom is perfect - exactly what I need but when I click merge, it comes "Unable to Merge" after a minute or so. Please help.

Hey ok so i just resolved the issue. What I did was, I went to Preferences and just clicked on "Purge Cache" under the "Performance" tab - and it seemed to do the trick. Apparently there wasn't enough space on my C drive for this operation to happen - if that's what it requires. 

Hope it helps whoever requires it.

I'm having a similar problem. It affects all my attempts to merge either panoramas or HDR. I was getting the same error message, but then it just started locking my computer completely so I have to reboot. I just tried clearing my cache as suggested and it made no difference. This is driving me mad!

Had the same problem and Adobe Chat support identified the issue as an older graphics card that was not compatible with the most recent LR update. Odd, considering that my computer is less than 18 mths old. The recommended solution was to reinstall the older version of LR via Creative Cloud. I'll try that.
