Has anyone encountered problems using pfNode::isect to test intersection with
geosets under a pfSwitch node?

I am able to correctly retreive intersection points with other geosets in the
scene but not with those under a pfSwitch node. I have included PFTRAV_SW_ALL
in setting the mode of the pfSegSet but still no intersection:
    segset.activeMask = 1;
    segset.isectMask = 0xFFFF;
    segset.discFunc = NULL;
    segset.bound = NULL;
    segset.mode =
        (PFTRAV_IS_PRIM|PFTRAV_IS_NORM|PFTRAV_IS_CULL_BACK|PFTRAV_SW_ALL);
    segset.segs[0].dir.set(0.0f, 0.0f, -1.0f); // down
    segset.segs[0].length = 50000.0f;

My development environment is IRIX 5.3, Performer 2.0, and C++ on a Maximum
IMPACT.

I would appreciate any help on how to correctly test for intersection with
geosets under a pfSwitch?
