So I am watching a course on rigging and most characters are human like with a normal spine and face is separated with their neck.
However, my character has it's face on the body. Here's an example
Is it necessary to include multiple bones for the spine or should I just use one giant bone?
Because they used a completely different face rig to do expressions, but I don't know how I would implement that if my spine is literally the face as well?
Also, if I want to make my character knod yes or no, is that possible to only using one bone? or would I need to create it like my image above then add loop cuts in the areas of my character where he would bend to knod his head up or down?
