I want to only make the arms of my armature move so I added an armature and parent the mesh to the armature using automatic weight. However when I rotate the armature the whole mesh moved, not just the arms. (Mesh arm is already at a 90 degree angle, I want to bring it to the mouth)
Is it because i only have one armature? Do I have to do the whole body? Do anyone know how to fix this? I've inserted my blend file below
