Hello,
I had read documentations about hand tracking in HTC Developers and VIVE Hand Tracking SDK(Vive Hand Tracking SDK Guide — Vive Hand Tracking SDK 1.0.0 documentation), but I have no idea hot to solve this problem.
There is a Unity sample scene in VIVE Hand Tracking SDK called "UISample".
Hand tracking status is "Running" on Unity Editor, but I builed a apk and install it on Vive XR Elite is "Error".
There are some images about my unity project. (Unity 2021.3.11f)
