I had to find the "VRCFury Gesture" controller and make 2 new Avatar Masks; one for each individual hands' muscles, and assign them to the left and right hand layers. I then assigned the "Mask for VF32 Base Mask" to the [VF32] Base Mask layer in the "VRCFury Gesture" controller, found the "VRCFury Additive" controller, and assigned it to the identically-named layer there too.

Then I made one last mask called "vrc_HandsOnly" assigned to both hands' muscles, clicked the avatar in the Hierarchy to open its controller (not sure how else to find it), and assigned it to the "[VF103] Defaults" layer.

As for Gogo, I fixed it by removing the prefab and dropping a reimported prefab onto the avatar in the hierarchy, then setting the Base, Action and Sitting controllers in the Playable Layers section in the Inspector to ProxyBase, ProxyAction and ProxySitting respectively.

Both hands now work, and so does gogo!

Thanks so much for the rip @yukix !

While the costume toggles work, the hand gestures are both mapped to her left (our right) hand. Any fixes?
