Error when attempting to Retarget Mesh Drivers

[Zack Johnson]

I use Retarget Mesh Drivers to apply existing JCMs to newly imported clothes on a character that I’ve already imported and Rigify’d with your Importer addon. For some reason I’m getting an error when I try to do it on this character… Any idea what’s going on?

Error: Python: Traceback (most recent call last):

I hadn’t used that tool for ages, and had actually forgotten about it. It doesn’t work with the new morph system so I removed it. There is a better way to add new clothes to an existing character: Change Armature + Transfer Shapekeys, cf https://diffeomorphic.blogspot.com/2021/07/changing-outfits.html. Since you rigified the body armature, you need to do the same thing with the clothes armatures before changing armature.
