This is something that might not be the fault of Topaz - I get the feeling Lightroom is causing this intermittent problem. I want to see if anyone else experiences these two problems:
When calling Denoise AI or Sharpen AI in LR, at times the TIF returned to LR does not have the changes made by the AI program. If I try to remake those changes in that same picture (in my case always a RAW file) it still does not work. I need to close LR, open it up again and then I can make the needed changes in that picture.
I have LR set up to include Sharpen AI as an available plug in. After some number of days Sharpen AI is lost as a plugin option where Denoise AI is listed in its place in addition to its status as working within LR. So I have to go into Edit>Preferences in LR and reset Sharpen AI as a plugin again.
Note that no software updates in AI or LR were made during this time - you can’t predict when either will happen - you just keep on the look out for it.
