Does it *have* to be like this? Or is it just left like this cos the rotation remains along the X and that's all the matters?
Hi Charles,
The bones 'can' be oriented any way - but the most logical way is to have one of the axes line up with the world. That way at least the X rotation matches.
Having the Z facing backwards is ok too - but it does mean that the X rotation will be reversed (so the other way is better)
I can see you have a question in another thread so I will elaborate over there.
