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).

  • $\begingroup$ It also works with L. and R. prefixes and Left. and Right. prefixes work too and also Left_ and Right_ prefixes too :D $\endgroup$ – Faceb Faceb Dec 21 '16 at 20:34

Yes bones are mirrored if you enable x-axis mirror and as long as everything in the name is the same except 'Left' and 'Right' and can even be directly next to a letter if you use it as suffix. If you use 'Left' and 'Right' as prefix, then separate with '.' (period) or '_' (underscore)

But if you use 'L' and 'R' it cannot be next to a letter, but has to be separated with '.' (period) or '_' (underscore)

For example prefixes:

  • L.Bone and R.Bone
  • Left.Bone and Right.Bone
  • L_Bone and R_Bone
  • Left_Bone and Right_Bone

or suffixes:

  • Bone.L and Bone.R
  • Bone.Left and Bone.Right
  • Bone_L and Bone_R
  • Bone_Left and Bone_Right
  • BoneLeft and BoneRight

enter image description here

  • $\begingroup$ Ah - maybe that's why it's not working. I somewhat oversimplified my example - I'm currently rigging a spider daemon (which means some fairly complex bone naming, particularly as I want things to alphabetise in a certain order), and I'd previously been told that the regexes were able to work in the middle of a bone name. I'll get back to you on that one. $\endgroup$ – RagnarokEOTW Dec 21 '16 at 21:12
