Hi Mason,
there is no format for that, you just write the path to the line, like:
and it is possible to set multiple folders, which you need to separate using semicolon.
Real-time assistance was mostly created for ENT license, so I suppose the issues using PIN are because of that. But I tested this using PPI and for me it worked. Do you have created a BAT file or are you adding the command to the console view?
What do you mean by getProjectCommand? There is no such CLI command for RealityCapture.
