I would ask you to check the image assignment for the orthophotos again.
The optimal photo of the surface is not assigned, as can easily be seen from the attached example. Example 1 is the automatic Ortophoto, example 2 the post-processed version.
In this example, all photos had to be exchanged to get an acceptable surface.
I have often pointed out this problem without any change on the part of agisoft. I like to work with Agisoft a lot, but I have to exchange hundreds of photos for every project, which in the long run becomes too much for me and is unproductive for our office.
I am happy to help and offer my support.
