After working on it for some time, I'm making available my "hand rig with three fingers" for free! Just enter $0 amount and download (be aware that the free version doesn't include any animation and only comes with very basic shaders).
The hand rig features:
* IK/FK toggle and snapping for the fingers
* Layered controls
* No shapekeys (actually a feature)
* Useful for both newbies and experienced animators
No add-ons required! All required scripts are included within the .blend and will auto-run when opening the file.
For a small amount you can also have the animated file, improved shaders, studio lights/background, and the GAME-READY rig version (you'd probably need to apply the subdivision surface modifier if you need that).
The rig is free to use, provided that the you respect the CC-BY license and include the credit: Hand Rig by Andy Cuccaro
