Animation and Rigging Tools: FAQ, Known Issues and Feature Roadmap

I’m not quite sure if it’s me who does things in the wrong order or if there is an error, but after loading one of my character with ‘Edit Character’, I get this error message when I try to press Skeleton Placement. (Maya 2015)

# Error: TypeError: file …/MayaTools/General/Scripts\ART_skeletonBuilder_UI.py line 10831: ‘NoneType’ object is not iterable
