This is a pretty simple problem that is driving me crazy, so I’ll be concise: How to create a root bone with rigify?
I’m animating a semi-human character using a modified version of the default human rigify armature (no legs, less fingers in each hand, and more) and, well, once I merge the armature with the model, it uses the only spine bone as root bone—my armature only has one spine bone—and therefore I can’t animate the spine, which, as you know, is a pretty important bone.
Another feasible alternative would be to use the make-it-yourself option of rigify; in that case, I would appreciate if you could tell me what the root bone is called. Each bone has an intuitive name, but I can’t seem to find the one I’m looking for. Then again, in this case, I didn’t look too hard to due time constraints. I just had to wish it would work out. It didn’t.
