This is supported for explicitly specifying 3D tex coords, but you do
not have the individual attribute support in the geoset. You must
instead use:

PFGS_PACKED_ATTRS

Look at the man page and you will see the following 3D texture packed
formats are supported:

PFGS_PA_C4UBN3ST3FV3F, PFGS_PA_C4UBN3ST3F, PFGS_PA_C4UBT3F

Cheers,Angus.
