Hello,

I have a command line batch file, that takes a point cloud, and slices it up into 1.5m cubes. Then exports it.
For some reason it has been really slow with larger, spatially, point clouds. For example, manually going through the process in the application, takes about 25 minutes total, and generates roughly 10,000 files. The command line version after an hour, had only generated 10 files, all with less than 5 points in them. Most of the files were generated within the last 10 minutes, of the hour.

Is there something wrong with my batch file? It is almost like it is processing all the empty cubes between everything?

Do you have large coordinates maybe? In this case you have to explicitly tell CC how to handle them in command line mode (with -GLOBAL_SHIFT).
