Hello ! 

I'm encountering 2 errors ​related to Virtual Button​ when i press Play​ in Unity editor (tried in 2017.3.1p1 and 2017.3.1f1).

I have already tried to

• Close and reopen the project Unity
• Download the latest version of Unity
• Open a brand new project on Unity 
• Download Official Vuforia Asset sample from Unity Asset Store ( even in this project the errors appear)
• Trying different settings of the Virtual Button 
• Change the Image Target by another 5 stars one.
• Change the position of the Virtual Button

Here are the full errors messages :



1/ "Failed to update virtual button VirtualButton at startup

UnityEngine.Debug:LogError(Object)

Vuforia.ImageTargetBehaviour:AssociateExistingVirtualButtonBehaviour(VirtualButtonBehaviour)

Vuforia.StateManager:AssociateVirtualButtonBehaviours(VirtualButtonBehaviour[], DataSet)

Vuforia.StateManager:AssociateTrackableBehavioursForDataSet(DataSet)

Vuforia.DataSet:Load(String, StorageType)

Vuforia.DataSet:Load(String)

Vuforia.DatabaseLoadARController:LoadDatasets()

Vuforia.VuforiaARController:Start()

System.Delegate:DynamicInvoke(Object[])

Vuforia.DelegateHelper:InvokeDelegate(Delegate, Object[])

Vuforia.DelegateHelper:InvokeWithExceptionHandling(Action)

Vuforia.VuforiaBehaviour:Start()"

2/ "Virtual Button area rectangle could not be set.

UnityEngine.Debug:LogError(Object)

Vuforia.VirtualButton:SetArea(RectangleData)

Vuforia.VirtualButtonBehaviour:UpdateAreaRectangle()

Vuforia.ImageTargetBehaviour:AssociateExistingVirtualButtonBehaviour(VirtualButtonBehaviour)

Vuforia.StateManager:AssociateVirtualButtonBehaviours(VirtualButtonBehaviour[], DataSet)

Vuforia.VuforiaARController:Start()

System.Delegate:DynamicInvoke(Object[])

Vuforia.DelegateHelper:InvokeDelegate(Delegate, Object[])

Vuforia.DelegateHelper:InvokeWithExceptionHandling(Action)

Vuforia.VuforiaBehaviour:Start()"

​Even if those errors appear, the Virtual Button seems to work, just I feel like it is hard to click.

If somebody knows how to fix those errors I would be grateful.

Please find attach to this discussion few pictures that highlight the issue.



Thank you,
