Hello yoli,
In Standard edition you can try to manually reproduce the script workflow:
- align images in the original chunk,
- resize region to the area of interest (may be also handy to do that in Orthographic view mode in the Model view using one of the predefined views) or disable certain set of cameras in the chunk,
- build dense cloud,
- duplicate chunk,
- resize the reconstruction region to another area or enable another group of cameras,
- build dense cloud in the chunk copy,
- repeat several times if necessary,
then if you need to merge the chunks back, use Camera based chunk alignment option. Also it may be handy to move all the cameras to the folders in the Workspace pane before the first chunk duplication - it would help to remove the camera duplicates after merging the chunks back.
