Hello,

I often use actor-\>GetProperty()-\>SetOpacity(opacity); with the standard vtkActor.  
However, I notice that whenever I try to call the same method to set the opacity of vtkActor2D’s,  
it turns out that there is no effect.  
Is there anything else I need to do in order to get it working with vtkActor2D?  
Have any of you ever encountered this issue?

Thank you
