So I followed the tutorial and I love how it turned out. I put it on Sketchfab, and clicked the "don't render" button for the cockpit rivet path that the tutorial described. In Sketchfab, the path appears, but not the rivets.
The same will happen if you render within blender. The rivets won't show up unless showing the rivet_02_path during render. So, have to turn on show during render for the path. I guess because the rivets are parented to the path.
