Hi there!
I am trying to recreate a scan that was tested on set with an older version of PhotoScan, but I get vastly different results with newer versions of the software.
With seemingly the same basic settings they got a decent headscan from a set of photos using version 1.1.6 Build 2038, while I can only align half of the images with version 1.4.0. Playing with different settings yields similar results, matching only one side of the face and not aligning the other half of the images.
Are there any basic settings I'm overlooking, that could help with that?
