Copy drivers from one Armature to another of the same kind

Question

I have a mesh/armature combo, which I developed in a good amount of steps. The first iteration has drivers for bones which drive other bones of the armature. While developing the neither the armature nor the mesh where topology-wise changed. In the current last iteration I noticed (too late) that those drivers got lost somewhere. The first iteration and the current iteration are in two different files.

How can I copy/transfer those drivers from the first iteration of that armature/mesh to the current last one?

PS: I cannot provide a *.blend file. It is not my decision.

Answer 1

• File append from the menus allows the Blender User to move an armature from one file to the other.

• Now the two armatures are in the same file.
• Now you can copy and paste Python Scripts or drivers from one armature to the other. This can be done manually or from another script. For small amounts of copies I suggest the task be done manually, otherwise via Script.

• Of course you may be able to just copy and paste the text of the driver from while file to the other. Two Blender files can be open at once.

• This proposed answer is intended to be a high level guide to complete your task. This is not a tutorial.

• We have not discussed the particulars of a simple copy of a driver from one object to the other. The detail required to do so was not given in the original question.
