Hi,

I have 2 pfGeodes under a group and wish to use
pfGetCullResult to determine which are culled.
I am getting the following behaviour:

- pfGetCullResult gives the correct result when
called in a pre-cull callback on the 1st geode

- pfGetCullResult gives an incorrect result when
called on the 1st geode in a post-cull callback.
It always returns (PFIS_MAYBE | PFIS_TRUE | PFIS_ALL_IN)
ie. it claims the node is entirely inside the viewing
frustum, even when the node is not visible

- pfGetCullResult gives an incorrect result when
called in a pre-cull callback on the 2nd geode.
It always returns PFIS_FALSE ie. it claims the node is
entirely outside the viewing frustum, even when the
node is visible

- pfGetCullResult gives an incorrect result when
called in a post-cull callback on the 2nd geode.
It always returns (PFIS_MAYBE | PFIS_TRUE | PFIS_ALL_IN)
ie. it claims the node is entirely inside the viewing
frustum, even when the node is not visible

Does anyone know what may be causing this?

cheers
steve
