PS Alpha Channel Masks Prevent Display Of Thumbnails
« on: May 24, 2021, 07:02:44 AM »
If my layered Photoshop TIFFs contain a layer mask from an alpha channel, the thumb/preview won't display properly in PM+. If I disable the layer mask and resave the TIFF, thumbs/previews display just fine.

[UPDATE] Actually, it's not the layer mask causing the problem. It's the Alpha Channel.

Known issue.  It will be addressed in the next build of Photo Mechanic 6 and Photo Mechanic Plus.
