Yes, this is possible if the characters all have the same proportions (if the length of their limbs, the distance between the joints are all the same).

No in all other cases, sorry. This being said, it’s quite quick to create a bunch of bones and run the Auto-Rig, not much longer than having to reposition existing bones (it may even be faster due to performance issues with rigged characters).

We could implement a tool to reposition already rigged bones, that’d be a great new feature in Duik, but it’s too complicated for now and all the other great new features we have to add first.

We need more funds to correctly work on Duik and improve it: you can donate or join us and get a membership with exclusive perks.
