SetOpacity on Actor2D

(Marcel Santos) #1

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
