Hi David,

I've now had a chance to look at this problem and have been able to
reproduce on a series of dicom files I have here.  This osgvolume
feature used to work before the transition to osgVolume, and relied
upon the update traversal triggering an update of the ImageSequence.
I've briefly looked into why osgVolume isn't calling the image
sequence updating and it looks down to the decoupled way that the
internal volume scene graph is managed - because it's decoupled from
the main scene graph it doesn't recieve an update traversal like a
normal scene graph.

I have to head out right now, but by on my return I'll fix
osgVolume::VolumeTile so that it passes on updates to the ImageLayer
which contains the ImageSequence.  I'll will fix this prior to the
OSG-2.8.0 release.

Robert.
