Every time I open Detail or Clarity, all the Preset previews get created again, every time. I can’t find an option to save them. Is this default behavior?
You need to explain what product … e.g. Studio Detail, Detail plugin etc.
Also what you mean by recreating preset previews because they will need to be created otherwise you won’t get previews of the current image.
@edgework this is behavior displayed in the previous versions of Detail and Clarity. Only Detail 3 and Clarity 1 have this behavior. The update to Detail in Studio and Clarity in Studio have corrected this problem. Please see the update articles here for more information on all the changes we’ve been making to Topaz plugin products recently:
The preset preview generation is quite slow in previous versions, which is why we fixed it in the updates
