I’m working on understanding rigging at a very basic level and while working through a tutorial on foot/leg rigging, I came across something weird. The logic is… let’s say, unusual.
If anyone can explain how and why this makes sense, please do.
In the top armature, the Z axis of the selected bone points down; in the bottom armature, the Z axis points up. Yet both bones have a Roll of zero (0).
What’s really interesting to me is that rotating bones doesn’t seem to have any affect on the roll. Rotate a bone 180 degrees around the X axis and the Z axis still points in the same direction as before you started.
Seriously, if anyone can explain this, please do.
