Is it possible to set bones as the X-axis mirror of each other other than with the .L and .R suffixes?
For example, is there some option where I could manually convince Blender that "Left_Thigh" and "Right_Thigh" are a pair (and thus mirror any edits on one to the other)?
I have to export to an engine that doesn't like periods/full-stops in bone names, and I'd really rather not have to keep swapping the names back-and-forth every time I export for testing.
Any answer is appreciated, even if it's "No". (At least it'll save me time barking up the wrong tree).
