I’ve noticed with the 4.8 update / latest dropbox files for ART that I can’t actually open the mannequin character, either the export file or the rig file. I get this error when I try via the “Edit Existing Character” menu:
I’m using Maya 2013, and haven’t changed anything with my setup since 4.6 - only updated ART’s maya tools path and my userSetup.py. It seems like the tool works fine aside from that.
