It seems only the arms are loaded from the collection in the source files, but I can see the Hidden 11 and Rivet_EDIT armature in the outliner but they're grayed out.
Hey Colby,
The Rivet_EDIT is just the arms. It is the version I used to swap out the geo for the arms to drop off in the example.
That file has not been updated to work with 2.8+ so just use the normal Rivet version. (That has the full body)
Hope that helps
Thanks, I found the full character. Awesome rig by the way!
