Just for clarification, what do you mean by: “alignment does not reach 100% and when we are trying to export the “.rcalign”, we do not receive the file”? That the alignment is not finished or that not all of the images are aligned?
What is happening, when you are trying to export .rcalign file? How are you exporting that?
I suppose you asked something similar before (to select some images and not use them). Unfortunately, this is not doable in RealityCapture, it uses all imported images.
Looking at your picture, it seems that all images were aligned into one component (as all of them are green).
