I was under the impression that only one FIFA 14 head model's neck had to be fixed to serve as the base for every other conversion, but maybe I misunderstood. But hopefully @tokke001 can figure out a permanent fix for this neck issue.
@Lagwagon93 we need your expertise bro. I'm not back at full Blender understanding just yet. You literally just have to edit one FIFA 14 head model to serve as the template. We need you to step up and make this penalty lol
