A First Look at the Hand Model
First, import a hand model into your scene, such as the provided GleechiRig in ThirdParty/VirtualGrasp/Resources/GleechiHands.
Next, link it into its place under Sensors → Avatars → Skeletal Mesh, by dragging and dropping its SkinnedMeshRenderer (which you can find directly under GleechiRig in the Hierarchy) into this slot.
Conditions for Avatars
In Pro-versions of VG, you can replace this model by any other skinned mesh renderer that you import into the scene, but there are certain conditions on which kind of skeletal meshes are supported.
As a rule of thumb, the rigging / model hierarchy should be same as the model in the project:
- 1 avatar should include 2 hands (its SkeletalMesh structure),
- 1 hand should include 5 fingers (no extra bones), and
- 1 finger should include 3-4 bones (with or without fingertip). If a fingertip is missing, VirtualGrasp will estimate its position, but it is recommended, and also very easy in Unity to add missing fingertip bones manually.
