[vtkusers] vtkAssembly and visibility

[Jean-Baptiste Estival]

Hi all,

I have a strange behaviour with vtkAssembly.

My app has some assemblies containing actors. I need to hide a whole 
assembly. But vtkAssembly::SetVisibility(0) or VisibilityOff()
does not work. The renderer seems to use the visibility of each actor. 
Is there a way to hide all actors in an assembly with vtkAssembly ?

Tanks

best regards
