Every Sunday morning at approximately 11.00am I take an HDR Pano of our back garden (yard in US terminology) from the balcony of our bedroom. I usually take about 60 shots 3x20 HDR. I Process these in Lightroom to give a large panorama. I started in January 2014 and can check the way the garden has changed due to human effort and the way the the various plants grow, flower and then wither through the seasons. Yesterday I took the photos and imported them into Lightroom. My usual strategy is to then highlight them all and click on HDR Pano, then go go and grab a coffee whilst Lightroom works is magic. However yesterday it would not accept anymore than 6 (2x3). I tried all the usual strategies we adopt when a computer misbehaves, restarted the app, restarted the computer to no avail. Lightroom is up-to-date, I have the monthly subscription. Has anyone else met this problem? Can it be reproduced on other machines. By the way I am using Windows 10 on a modern powerful computer.

Your images are too large to be processed by Lightroom. How much RAM does your modern computer have?

I have seen this with Nikon D850 panorama component images, where there are 8 individual shots and the combined size is > 3 Gb. My solution was to merge in Photoshop which is better at handling memory intensive tasks.

Honestly I can't help with your issue, but I think your project is great!
FIVE years of consistency is amazing, I think you could (and should :) ) work on making a nice timelapse with them

Best guess since it has been working for you it might be scratch space. Where is it and how big? Go to edit > preferences and poke around. I since my SSI drive was too small I had to move my scratch space and enlarge it on my external drive.

Good morning and my I salute your commitment!!

Yes, just Sunday, the pano function of my LR took over an hour to put together a 7 shot pano. The initial review went quickly, but rendering was the problem. Did all the same moves, no help. Stopped it the first time when I noticed it was stuck about 40% of the way through, no help.

I haven't contacted adobe yet, but clearly a problem.

Doug,

Your response triggered me to my problem, “ not enough scratch space”. How did you move to your external drive? I have a windows lap top, and 1TB external hard drive?

I too have had a similar problem also solved by using Photoshop for around 30+ images.

I did that many years ago. I had watched a series of videos on LR before I did the installation. I wanted to understand the data base piece. I was also shown an alternate way for a directory structure naming convention. The default is dates and what I did on some date was of zero value me. Others may be better at recalling by date. I use something like year 2019 and the directory names under are where and when. Zoo 12-1-19. I can find most of my stuff just looking in the left pane. If not I can always use the search.

I keep my catalog on my local disk and I have 2 terabyte external for my photos and a second for a backup. I would look to youtube for guidance but remember it was not hard.

I run into the 4gb max in PS when stacking or doing panos. Adobe tells me it is scratch disk but increasing the scratch disk size did not help.
Using only jpegs helps keep files small but bypasses the benefits of raw files.
I have cropped the image in LR then sync up all images with the crop and other adjustments. Keeps the file size down but can be more labor intensive and does not always come out with useable images. Still working on this issue.
MacBook Pro 2019, 32 gb RAM, 1 tb SSD internal, 2 8 tb and one 2 tb platters, 2 2tb and one 1 tb SSDs. Plenty of backup.

Consider these areas before you call Adobe because it sure sounds like a system issue:

What is your system's RAM capacity?
Did you check the Task Manager performance tab to see what % of CPU and RAM were being used?
What is your Lightroom swap file size and % of RAM it will use before swapping to your HD?
In Lightroom/Edit/Preferences are you using your system GPU? Try turning LR's use of the GPU off.
How full is your system drive? Have you ever done, from File Explorer, right-click on the system drive and choose Properties/Disk Cleanup? You'd be amazed how much crap Windows saves all over the place.

I have had pano merging eat up 99% of CPU capacity as well as 80% of system RAM, and I have 64 Gb mainboard.

To your Last point. many applications will take advantage of all the ram available to speed things up. It does not necessarily mean it demands that much space. Don't want the OP to think he will need 64 to survive but it is good reason to have lots of ram in general.
