Checking it out, the scene loader is basically perfly.C with some bits added
to add my own data to each object, the call
if(PackedAttrFormat)
{
        pfuTravCreatePackedAttrs(scene, PackedAttrFormat, 0x0);
}
is pretty definately not made, assuming that is, that this is the bit which
would pack the arrays.
The object files are Inventor files,
the only other thing I do is add a node above each object to move them around.
Copies I make of the objects while they're moving, show the distortion I
would have expected, but are again static.
