https://forums.autodesk.com/t5/remake-forum/new-and-final-windows-beta-pre-release-build-of-memento/m-p/6319515#M2137 Hello, I meant Photo Validation. I updated the Nvidia Driver and reinstalled Memento. Now the photo validation works and apparently also the local reconstruction (I`ll know better tomorrow). Thank you for your help!
