Have you tried substituting a different render for the VolPro to see if this
goes away. I understood there were some limitations intermixing volumes and
surfaces with the VolPro...if you have a test script I would be happy to test it
on my machine. I'm running both vtk3.2 and a fairly recent nightly both with
VolPro installed on WinNT...regards, john

I have multiple vtkActors and vtkVolumes set as inputs to a single
vtkRenderer. I'm using volumepro 500 hardware with the vtkVolumeProMapper
for my volumes and vtkPolyDataMapper for the actors. My problem is that my
actors have transparency (opacity of 0.2), which works fine until I
introduce a volume into the scene. As soon as the volume is placed in the
scene, all of my actors become fully opaque - the volume on the other hand
maintains the correct opacity characteristics.
Has anybody else seen this? Any insights?
