I'm encountering a problem with my ACS4 created rig. If I update my model and then swap out the old with the new (they have different names) then the expressions on the spinecontrol, root, and root dir are broken and have to be manually updated with the new object name. Am I doing something wrong? I was thinking of just naming the new object the same name every time and backing up the old one as a work around. I do have several scenes though that the animator already worked on that I will have to update. Any ideas?
