Hello cojeffj,
I think that the split-in-chunks script should be completely re-written, if it should properly support network processing functionality.
It may be not that straightforward, if the custom workflow parts of script should be also executed as a network task.
It might be easier, to create the pack of sub-tasks for multiple chunks (like dense cloud or mesh generation) and send them as network task to the server, but the script should be then monitoring, when the task is over on the server, then re-open the project and proceed with the further steps, which would require re-assignment of the variables.
