Hello!

I think i found a quite anoying bug for animators, if you select two bones, with individual origins and move them with gymbal orientation on a single axis, when you go to the curves, you can check that all the three axis (Z,X,Y) are moved around. Only one should be moved since you're using individual origins + gymbal orientation.

Exact steps for others to reproduce the error

  • I tested the problem in different computers, with different versions of 2.8 using Spring rig and using Boris rig in 2.79 and 2.8. In all of them the problem occurs
  • Open blender 2.8 with spring rig (for example)
  • Divide the screen in two parts, one with the viewport view and the other one with the graph editor
  • Select both eyebrow general controllers
  • Put the pivot point in Individual origins
  • Use gymbal orientation
  • Move both eyebrows in Z location (check that it sais "along gymbal Z)
  • Check the graph editor, you'll see that at least two axis are moved around.

    OBSERVATION: sometimes it DOESN'T happen, but if you do it several times, at some point it happens (just do it fast 5-6 times and it should happen)

Can you attach a minimal example file?

Yes, of course! https://imgur.com/a/KVapWs7 here you have the images with step by step. Maybe it's normal but I think it should just move around one axis, am I wrong? Anyway, if you know how can i attach the .blend file I'll upload it.

If you click on the "cloud" icon just about the comment input field, you will get a file dialog that you can use to upload the .blend file.

I think i've done it alright, but im not sure

@campbell any input on this? It seems to work better when using local transformation mode.

@Josep (Velorth) please give us a minimal example file, this file is far too big to dive into.
