I have match all the bones with the riggify addon. Clicking on the generate button the generated rig is not on the mesh target.

hand rig.blend (2.1 MB)

How to generate the rig on the target. I have set the pivot point and check rotation and scaling everything looks ok. May i know where im going wrong and how can i make the rig on the target to control. Any suggestion or help. Thanks

Make sure your mesh location is 0,0,0. That is where rigify generates the rig.

Thanks Yeah i got it . But after target and bind with the mesh its not rig naturally or folding of the hand not working.
