I keep getting alert to "Regenerate previews for HDR edited images to render HDR in Library Views"

[robgendreau]

As stated, in Classic I periodically get a yellow alert message with ""Regenerate previews for HDR edited images to render HDR in Library Views" and a "Regenerate" button. If I click it, it can take hours to complete. The progress bar shows "Refining Previews for HDR." So far I've been too cautious to quit LrC while it's running. So it's a big annoyance. And note it has done this numerous times, so it must be "refining" images I've already imported unless it's very very very slow with new imports.

I am using 14.1.1. Everything else works fine. I make extensive use of the HDR feature, and so quite a number of images are now imported with that setting in Develop enabled. I do it by default now.

I want to  know why it's happening and how to prevent it. And if I can dismiss the alert without consequences. And if I can quit LrC while it's running. 

Thanks, Rob

Hey @robgendreau,

When are these previews regenerating? Is it after you perform an action, or do they happen randomly? How often does this occur?

One thing we can try is making sure the option to "Replace embedded previews with standard previews during idle time" in preferences is unchecked so that previews are not generated as often.



Also, in the import window, check what option you have for building previews. "Embedded & Sidecar" is recommended, but you could try changing it to "Minimal" to see if it helps.

Let me know how it goes!

Thanks, Alek
