I’m rigging a character with the new armature system and I was using the limit local axis option for a finger. But the bone axes are not lined up and down with the finger after I had recalculated the bone roll angles. Originally I was just going to limit the z-axis so the finger would not hyper-extend. But the bones aren’t lined up to do that.
My question is: what does recalculating the bone roll angles actually mean? What does it do? Is it necessary, or can I rotate the bones manually in edit mode so that their axes line up the way I want them to line up?
