DMap intermediate output - ZS
We are all familiar with the need to set DMap Contrast threshold manually about 50% through the process. Rarely (OK, occasionally) I pick the wrong value and the final image looks like crap. Is there a way to go back to the 'set contrast threshold' slider without having to start the stacking process over again? I'm using ZS Pro. Maybe I'm missing something simple.

Re: DMap intermediate output - ZS
Caching of DMap intermediate results was recently added to the beta, has not yet propagated to the full release.
From https://zerenesystems.com/cms/stacker/softwaredownloads/currentbeta :
Then run Zerene Stacker, go to Options > Preferences > DMap Settings, and either place a checkmark on "Cache DMap pass 1 info for faster work with multiple thresholds", or confirm that there's already a checkmark there. It's a Pro-only feature, so non-Pro licenses can use it for 30 days but have to acknowledge starting that trial.
With that box checked, the first time you run DMap with a particular set of images and all the associated settings, the results of pass 1 will be saved for potential reuse. Any subsequent DMap that specifies exactly the same set of images, in the same order, with the same radii settings, same alignment settings, same preprocessing settings, etc, will find the cached results of pass1 and will just read those into memory instead of recomputing them. The effect is that you do the Stack > Align & Stack All (DMap) the same as first time, but on the second and subsequent DMaps with all same everything, only a few seconds pass and then the threshold slider appears.
In case of any difficulties, please email support@zerenesystems.com since that may get my attention faster.
