    i am trying to great vuforia model target, but i got this error when i setup more one target in the same scene.

    The error:


    Exception in callback: Failed to activate observer for behaviour 'nomad_creo'
    UnityEngine.Debug:LogErrorFormat (string,object[])
    Vuforia.Internal.Utility.UnityLogger:LogError (string,object[])
    Vuforia.Internal.Utility.Log:Error (string,object[])
    Vuforia.Utility.ExtensionMethods.DelegateHelper:InvokeDelegate (System.Delegate,object[])
    Vuforia.Utility.ExtensionMethods.DelegateHelper:InvokeWithExceptionHandling (System.Action)
    Vuforia.Internal.Core.Engine:OnStart ()
    Vuforia.Internal.Core.Engine:Start (System.Action)
    Vuforia.Internal.Core.Engine:Start ()
    Vuforia.VuforiaBehaviour:VuforiaInitialized (Vuforia.VuforiaInitError)
    System.Delegate:DynamicInvoke (object[])
    Vuforia.Utility.ExtensionMethods.DelegateHelper:InvokeDelegate (System.Delegate,object[])
    Vuforia.Utility.ExtensionMethods.DelegateHelper:InvokeWithExceptionHandling<Vuforia.VuforiaInitError> (System.Action`1<Vuforia.VuforiaInitError>,Vuforia.VuforiaInitError)
    Vuforia.Internal.Core.Engine:add_OnAfterVuforiaInitializedPublic (System.Action`1<Vuforia.VuforiaInitError>)
    Vuforia.VuforiaBehaviour:Awake ()



    Someone can help me?

    Thank you

    The model target that is giving me this error I have tried by separately in a scene that alone and has not given me this error. Sorry for my English that is not very good, but I hope you understand my problem
