Hi there:

I'm having some CULL problems. I have created a simple terrain
using triangle mesh. The terrain is tiled with each tile belonging
to a different geometry node. As the view is traveling across the terrain,
tiles in the viewing frustum will be culled and not displayed. I've added
post cull callbacks to the pfGeode. In the callback, pfGetCullResult()
returns zero, pfGetNodeTravData() returns all 1's for CULL and DRAW mask, and
the sphere returned by pfGetNodeBSphere() is set up properly.
I can get the tile's to "pop" in and out just by modifying the view heading.

I've run out of ideals to debug what is going on. Any help would be
appreciated.
