I'm trying to use a billboard symbol from style gallery in globecontrol using IFeatureLayer
but I have a problem, the symbol is showed like a rectangle and not show lik billboard

In attachments the image of my result

I can manage style gallery symbols using IFeatureLayer ? How I can do ?


This is my code:

Private m_objGlobeControl As AxGlobeControl
Private m_FeatureLayer As IFeatureLayer

Public Sub AddFeature(ByVal stDati() As st_DataTarget_3d)
End Sub

Private Sub Create_Layer()

        Dim pFeatureClass As IFeatureClass
        pFeatureClass = CreateFeatureClass(esriGeometryType.esriGeometryPoint)

        Dim pFLy As IFeatureLayer
        pFLy = New FeatureLayer

        With pFLy
            .FeatureClass = pFeatureClass
            .Name = m_NameLayer
            .Cached = True
            .Selectable = True
        End With

        Dim pSymbol As ISymbol = LoadStyleSymbol()

        Dim pColor As IColor = New RgbColor
        pColor.RGB = RGB(0, 255, 0)
        pColor.Transparency = 255

        Dim markerSymbol As IMarkerSymbol = TryCast(pSymbol, IMarkerSymbol)
        markerSymbol.Color = pColor
        markerSymbol.Size = 15

        Dim pRend As IFeatureRenderer
        Dim pSimpleRend As ISimpleRenderer
        Dim pGeoFL As IGeoFeatureLayer

        If Not IsNothing(pSymbol) Then
            pRend = New SimpleRenderer
            pSimpleRend = pRend
            pSimpleRend.Symbol = markerSymbol
            pGeoFL = pFLy
            pGeoFL.Renderer = pRend
        End If

        m_objGlobeControl.Globe.AddLayerType(pFLy, esriGlobeLayerType.esriGlobeLayerTypeDraped, True)

        m_FeatureLayer = pFLy

End Sub

Private Sub AddingFeature(ByVal stDati() As st_DataTarget_3d)

        Dim pFeatureClass As IFeatureClass = Nothing
        Dim pFeature As IFeature = Nothing
        Dim pPoint As IPoint

        pFeatureClass = m_FeatureLayer.FeatureClass

        pFeature = New Feature

        For iConta As Integer = 0 To (stDati.Length - 1)

            If Not IsDBNull(stDati(iConta).Latitudine) And Not IsDBNull(stDati(iConta).Longitudine) Then

                pFeature = pFeatureClass.CreateFeature
                pPoint = New Point
                pPoint.PutCoords(stDati(iConta).Longitudine, stDati(iConta).Latitudine)

                Dim za As IZAware = TryCast(pPoint, IZAware)
                za.ZAware = True
                pPoint.Z = 25

                With pFeature
                    .Shape = pPoint
