So i made a scene with a CAD model and few object.
Using a guide from YouTube i changed the controller bindings and it works great.
In fact, all i good when i PLAY the game/scene.
BUT!!
When i Build the game, then the controllers revert to default.
The same thing with another scene i have made.
I found the solution, in case someone else have the same problem
Unitiy Editor → Window → Steam VR Input → “Open Binding UI” opens the “Developer Binding for Vive Controller …” (as you already did)
Do your settings
Press: “Replace dafault binding”: this replaces the according *.json files (bindings_vive_controller.json) in your unity game development storage location
Build your game exe
The bindings are now correctly exported to your game exe location and are saved in bindings_vive_controller.json
start your game exe → the controller should work properly now
