Constraint data on linked Armature Data (as in Shift+F1
Link from another .blend) is incorrectly linked to the
armature instead of the action.
Basically what this means is you can't edit the
constraints inside a linked Armature, for example use
the same armature but turn on/off or add an IK solver
depending on the scene.
1) Create an Armature and save the file.
2) Create a new file and link the just-saved Armature
Object (as in Library.blend > Objects > Armature) into
4) Create a NEW Armature
5) Link the new Armature to the Armature Data of the
6) try to add a constraint to the new armature! =)
All versions starting with 2.30 will stop you saying
"ERROR: Can't edit library data", whereas any version
up to 2.28 allows it.
Funny thing is, you can add and animate a constraint on
a linked Armature in 2.28, open it up in 2.3+ and be
able to move the keyframes for it in the Action window.
You can't actually edit the constraint's IPO in 2.3+
however, but if the IPO was pinned back in 2.28, it can
be edited just like any other IPO.
I've uploaded a zip with blend files of the above
steps. Please place the blend files in c:\blender so
the library can be accessed correctly.
