Just purchased Remask 5 a week ago and discovered a lot of problems when extracting the backgrounds of 20 TIFF's.
1* In the standalone version there appears no image name when you open an image.
2* Save Trimap/mask doesn't remember the folder location so you have to browse to the particular folder every time you save a mask (starting at "your computer").
3* Every time you save your end-result/export, you are faced with a panel asking you to fill in all the settings for export and this for every single image you do.
4* After opening a saved Trimap/mask it seems that all refinements of the mask and adjustment settings that are made are gone and you can start all over again.
5* Exported PNG's in this case contain artifacts/spots that are taken away before (with refining the mask) and are not visible anymore in the mask view or other views at 400% zoom and cost a lot of extra work later on in your photo editor. This is also in a realtime situation and not only with a previous saved mask and image.
*6 The background panel at the bottom never comes back when you reload an image and Trimap.
*7 The plugin works well in Photoshop, but not in Affinity Photo (layer mask doesn't appear!).
The application feels like a beta version and I wonder are there more people with these problems and more important how did you solve them?
Oh yes I stayed in RGB from the beginning till the end.
