I remember there was a trick to get the Object map (the one that resembles an edge mask) alongside the depth map in older versions... but Im not sure how to get it anymore
Its really quite a pleasant image and Id love to be able to export it but theres no obvious way to do it and its always deleted after the stack is finished...
If anyone knows a way to get it Id really appreciate it
If you save the result as a project (menu - File - Save project) and navigate to the project folder there will be a file opacity_map.tiff which could be what you want.
