I'm also having this same issue, I just attempted porting over the judge from BO2 and I was able to get each animation perfect. However after trying the raygun mkII, everything but ads fire works great. When I attempt to put the tanim on for ads fire it seems to be off centered to the right. I went back to my conversion rig for the judge and retried ads fire on that animation as well, and it's now showing off centered to the right. Would this happen to be a maya setting that somehow I changed with a keybinding?
