Hi Pablo,
the capturing is relevant here, as it depends for RC how the images were captured. Also, what is the overlap and image orientation.
I understand that other app was able to create a model from the data, but those data were captured by that application. As I wrote before, there can be used some information which are not able to use in RC.
Also, it would be nice to see the images and test them (if I remember there were some restrictions for it).
All needed metadata should be readable from image files. Which metadata do you want to use? Aren’t the information loaded in RC?
