This is the first time I've been able to export from Blender and Unity accepts the number of bones my rig uses so that's progress but now I'm getting a very strange error I haven't seen on the forum before. In the scene view everything appears to be just perfect. Inside the Avatar/Rig setup there is a bit of bone misplacement that I'd love to solve but that's not the main problem (unless that is the source of both problems). In play mode is where things really get weird. Everything is setup correctly under the Mapping section of the Avatar, so there are no problems with incorrect bones being assigned. Below I have attached a picture of the three views I mentioned before. If any more information is needed to resolve this I will provide whatever you need. Thanks a bunch in advance!
