Is there an order to enter photos or groups of photos in RealityScan ?

I sometimes do a scan in several times. In fact, I have to take photos from a different angle on large subjects. When I start the scan calculation, I enter the groups of photos (photos A) (photos B) one after the other. Sometimes the software is unable to reconstruct a single scan but calculates 2 different objects. If I reverse the order of the photos (photos B photos A) in the import, will the program calculate differently? The algorithm calculates the remarkable points between each photo and the next and the next (+1, etc…). But, conversely, is there “reverse engineering” when the algorithm arrives at the last photo?
