I’m having the same issue as Odysseus. It may be related to a serious issue i’m having regarding editing rigs. If i build a simple rig with just one extra joint, say a leaf joint for a jaw, i can’t go back to editing the skeleton placement for that rig after it is built. I get a popup saying that if significant changes are made to the rig it may mess up the skin weighting, I click continue, then the operation errors out. Here is the error:
# Error: ValueError: file C:/Users/Michael/Desktop/MayaTools/General/Scripts\ART_skeletonBuilder_UI.py line 10989: invalid literal for int() with base 10: 'Nothing counted : no polygonal object is selected.' #
I saw someone earlier in the thread have the same error, but that was a while ago, and it seems unresolved, or broken again for maya 2015 maybe?
edit: figured out that my problem lied in misunderstanding the difference between export file and rig file.
