Adding images and losing mesh?

I have started a project by uploading around 45 images, which gave a reasonably good initial result.  I tried to add some images (around another 45) to provide some addition coverage in few areas.  On resubmitting the project, I found that a decent mesh was created in the vicinity of the new photos, but  much of the original mesh had completely disappeared.  The original photos are still there and when I look at each photo, they are all still correctly stitched.  In another attempt, I renamed all 90 photos and resubmitted as a new project. I found that the result was an even more abstract mesh with only a small portion properly created.

 

I seem to be adding images, but losing mesh as I add them.  Ideally, I would like to "lock in" the original or acceptable parts of the mesh and have the software add to it, rather than try to recreate.  I have only created the model as a preview at this stage - would this make any difference?  I have also had the smart cropping feature enabled - should this be turned off maybe?  Am I missing something in my workflow?

It depends on the photographs. If there is high amount of overlap between 85-95% you should be getting good results with the service.

This particular article might help in answering some best practices techniques.

 

Smart crop is mainly used for objects, sculptures... that don't extend beyond the picture frame. So smart crop will try to leave your model of focus and eliminate the noise in the background. If you are trying to reconstruct urban area with images taken from UAV or some interior space, then smart crop is not recommended.

 

I really like the idea of keeping different versions of the model. Feel free to submit the suggestion directly to the ReCap's development team for future consideration in this IdeaStation.
