Hi @Sean Lu Thank you for quick response.
Here is how I am calling the vibration . Inside the UniversalControllerActions.cs I am calling
WVR_HVR.WVR_TriggerVibration_HVR(WVR_DeviceType.WVR_DeviceType_Controller_Left, WVR_InputId.WVR_InputId_16, 10000000,300,WVR_Intensity.WVR_Intensity_Normal);
Also ,I am always trying on the device with no luck.
