AFAIK this is not possible. When you pipeline your vtkPolyData through a
vtkPolyDataMapper and finally a vtkActor, there is just one
vtkProperties associated with the actor where you can set the opacity.
We too have a dataset with windows in it (actually it is a building) and
we will put walls and windows in different actors. If you find an other
way please let me know.
