P: Creating XMPs after import but before edits.

On MacOS 14.2.1, with Canon R3 and CR3 RAW files.

I don't use catalogs at all, just drag and drop raw files into Library, then edit in Develop. Just loading a directory of RAW files in this version just automatically generates XMP files for no reason, an old bug I haven't seen for many many versons.

As usual, XMP files should only be created when there are changes done to the RAW file, not just upon loading them in lightroom. It's a good system so I can edit galleries as needed, and then I can look in the directory and see if there are any photos I might have accidentally skipped over deleting by seeing there is no XMP associated with it.

It could actually be a bug with Adobe Camera RAW with your testing. Because if you have the latest Camera RAW instaled and still downgrade your Lightroom, it's still interacting with that new version. This would account for older versions still having this issue when you tested them, when they didn't have the issue as the versions came out with their corresponding Camera RAW versions.

Oh, and please review:

One of the bit of confusion here, is LrC behavior towards writing xmp files. The behavior is different outside of the Develop Module as opposed to during mods in the develop module. If that catalog setting to Automatically write changes to XMP is on, then they are written at all stages, except for a change in the "when" in the Develop Module.

Ah damn I think this could be it then, it says:

"Starting from the Lightroom Classic 13.0 release, we have changed the XMP writing frequency for the Develop module when Automatically Write Changes Into XMP is enabled."

Only thing is this did not happen in Lightroom 13.0 so it could be a separate bug. Testing it out, it imports the files in Library then automatically generates XMP files for every single file before any of the listed above occurs. So no changes in active image, no changing module, and not backgrounding or quitting the lightroom app.

Sort of correct. thing is the XMP creation is still going on at Import if you have that catalog option on. Change is only frequency of LATER changes to XMP files during Develop.

So, I am clearly confused.

You want xmp files or you do not want xmp files?

I want XMP files but the bug is that Lightroom Classic is generating them upon loading the RAW file.

The way it has always worked with generating XMP files is that it doesn't get created until you start editing the RAW file. So an unedited RAW file does not have a XMP file while an edited one does.

Double check your catalog settings, make sure the xmp box shown below as checked is not checked

and dang, an old catalog of mine, I need to undo that.

I don't understand, it's supposed to be checked, the bug is that it happens with it enabled. If I uncheck it then XMP is disabled.

If that's on, Lightroom creates an XMP. It's not on by default and it's not needed as everything is stored in the catalog. Unless you have specific reason for having it on, don't. Examples include sharing the files with others for editing, using with Bridge or for precuation in the very rare case of catalog corruption.
