Hi,

The callbacks are only performed if it's assigned action is performed and the 
visitor visits the node where your callback si registered(In your case: the 
update traversal).

But updating a node means not neccesarily that this node must be included in 
the scenegraph.

If you register your update function not your anaimation node, but  on any 
scenegraph node (for exampe the camera) your callback will be invoked and your 
node be updated, even if it is outside the scenegraph.


Cheers,
Torben
