Could somebody please help me?
I've constructed a visual database in Performer and I am rendering it on a RE2 (2cpu).
The problem is this:- When I update the vertices in a Geoset the bounding volume in the Geode
 doesn't appear to be updating properly. I try to force Performer to update by setting the Geodes
bounding volume to NULL with pfNodeBSphere( Geode, NULL, PFN_BNODE_DYNAMIC ) but
 it still maintains the original bounding volume. I've also tried replacing the Geosets with themselves
 in the hope this would force the bounding volume to be re-computed in the Geode (But still the same
 result). I've also tried removing parents and inserting them back in the hierarchy but with still the
 effect (bounding volume wasn't updated). Can anybody shed any light on this problem?
                 
        Thanks
