Hi John,
Sorry for the late reply. I was unable to reproduce the problem that you
are having. The pfVolume node was tested to work fine in a multi-pipe
environment using perfly. Can you please give more details as to how you
are using the node??
The callbacks not being invoked should imply that the node is probably
being culled out for the current channel. Check if the bounding sphere
being set for the node is correct (in pfVolume::loadFile()) with respect
to your scene. Currently it is set to a default value during the
initialization.
Cheers,
Praveen
