I'm trying to Import unity package
There is many Error
1.Assets/ViveSR_Experience/Scripts/DartGenerator/ViveSR_Experience_Dart.cs(2,7): error CS0246: The type or namespace name `Valve' could not be found. Are you missing an assembly reference?
I can run SKworks Demo
Where I lost?
Which example are you trying to run? The experience demo requires the SteamVR plugin right now - but I can help provide working examples here using the Vive Input Utility (VIU) Unity plugin (on asset store).
