As stated in the post, the hand models can be incorporated into your projects if you are using Unity.
The "....Controller Sandbox in Unity’s Hierarchy view. This spawns the virtual hands using our HandController script. From here, you can choose whichever virtual hand model you like. The “separate left/right” property of this script allows you to define the graphics and physics models you’re using for the left and right hand, respectively. Meaning you could give your character a bionic arm with just a few clicks.
If you’d like to peek under the hood at Hand Viewer’s source code, take a look inside our V2 skeletal asset package. Here’s what you’ll find, and where:
