Merge to HDR not Working in LR Classic

[David Eichler]

This just started happening. The HDR merge dialog opens and it seems to go through the entire process, but the merged image does not appear in LR, although the merged files are being created and appear in the same folder as the source images. I am using the current version of LR Classic and this feature was working fine until a couple of days ago. I have not made any recent changes to my system. Tried resetting preferences. I have tried this with several different sets of images. When I try to import the HDR files from the folder in which they reside, LR won't import them.

I've seen this behaviour once or twice but I found that for no reason the DNG is showing up at the beginning of the filmstrip, not next to the source files.  I've never changed the ordering in the library, so no idea why.  I reset the order and all is OK.  To verify that the files were being generated I temporarily re-order by file type and check my DNGs.

That is not what is happening for me. The HDR file is not appearing in Lightroom at all, anywhere. And the last time I tried to do a merge to HDR, I even got an error message telling me that this would happen, which I was not seeing before.

What's the error message?

Perhaps a catalog issue if you can't import the missing file(s) and they are not pulled automatically.  What happens if you make a new empty catalog and import some files and try an HDR?

It is even weirder than I thought. Many (but not all) of the HDR files, and an occasional image edited in Photoshop, are showing up in the LR Library in completely separate folders, outside of any master folders. The actual files are going to their correct folders on the hard drive, however.

I am going to take a wild guess that this is some bug having to do with LR's new catalog system. However, I updated to LR Classic 10 shortly after it became available and only started experiencing this problem a few days ago.

The catalogue system has not changed for years.

In your first post "When I try to import the HDR files from the folder in which they reside, LR won't import them." Any error message or are they just dimmed out? The latter would be consistent with "Many (but not all) of the HDR files, and an occasional image edited in Photoshop, are showing up in the LR Library in completely separate folders, outside of any master folders."

Physically, where are the originals? Are we talking Mac or Windows, internal or external drives or network or whatever?

Turns out it is a known bug. Didn't notice before, but LR is showing a duplicate external drive, and this where the folder/images mentioned above are appearing.
