struggling to stack tiffs

[simonun]

Hello everyone.
I love helicon, but recently started to export my raw files to tiff after doing retouching inside phocus hasselblad software.
Before i used to stack raws directly and never had much issue.
I am now noticing that tiff (which as exactly the same as raw files) give me way more errors (blurred plain surfaces) than dng.
I've tried all 3 methods, no luck.
Is there something i should do to avoid errors? Thanks!

Attaching a portion of the stack.

Hello,

That sounds like the images themselves are not identical. Are you sure the problem doesn't exist on the source images and only appears in the final result? Are you able to fix it with retouching?
Which version of Helicon Focus are you using, 8 or 9?

I am using the 8.3.6 version.
I can do a comparison as soon as i have some time but it's kinda weird - stacking raws works fine but if i export the raws to tiffs and stack those i have issues as the images

Did you compare the images themselves side by side, the original raw and the tiff you exported from that same raw file?
