Ok your above direction on the path, worked. I figured it was the command I had wrong. I also moved it to my downloads directory. It's process photos now. I think the example I the command tool is just not clear on that format. ./HelloPhotogrammetry ./folder-name output.usdz

open HelloPhotogrammetry  /Users/myuser/Documents/shoe  shoesimple.usdz It keeps asking for the input folder, I know the directions said it will work on an intell so its not that. I'm wondering is my command wrong? metry ; exit; Error: Missing expected argument ''
