I’d like to be able to toggle a labelmap volume in the slicer viewer. I thought it would work the same like with a segmentation.  
`laNode = slicer.util.getNodesByClass("vtkMRMLLabelMapVolumeNode")[0] laNode.GetDisplayNode().SetVisibility(False)`

However the display still shows the labelmap volume although laNode.GetDisplayNode().GetVisibility() does return 0. Am I doing something wrong here?

Volume layers work differently. You can use this method instead:
