You have an area (a city, or just a construction site) photographed and 3MX model completed.
Take photos of the new area of interestEnsure the new dataset includes enough photos to generate a good 3D model of the area that has changed.
Create a new block (in the same Project as the major area) with the new photos
Note:Using this method there are likely to be texture discrepancies at the tile limit (due to the capturing being done at different times).
