Hello,
I'm experiencing the same texturing issue (see attached image) in V 1.74 and have already shared this with Agisoft support.
Interestingly, in my case, the blurry patches only appear on the depth maps based mesh but not on the dense cloud based meshes.
Agisoft support suggested to use V 1.73 for texturing for the moment - in my specific case the texture turned out fine with that version.
best regards, Andreas
