I notice whenever I make a model and rig it that whenever I try to rotate the head. Which is the very first bone I make, it rotates the whole model instead of just the head. I went through all the weight paint and made sure it was only the head painted but this did not fix it. Does anyone have an idea of what it is?
Could use more info. And if you can, can you share the .blend file? Or just delete the armature and copy this guy: https://www.youtube.com/watch?v=cGvalWG8HBU
