Animation and Rigging Tools: FAQ, Known Issues and Feature Roadmap

Heya! I think you’re pretty much right on the nose with what you need to do. The only thing missing is to unlock the channels of your mesh (they get locked when a skinCluster gets added), and scale the same amount. If the pivot of the mesh/meshes isn’t at 0,0,0, I recommend grouping your geometry and scaling the group. I tend to scale both the master control for the joint mover and that group at the same time so I know they’re lining up exactly right.
Hope that helps!
