Hi,
The update callback is done to be updated each frame in the traverse()
method.
Rewriting it is necessary to update it.
So add a callback on the decorator and update it in traverse() method.

Vincent

Hi all,
I'm trying to make "blinking" a part of my scene by adding a
"decorator" node (a group node with a shader) like this:
Original graph
root
|
_ _
| |
node1 node2
"decorated" graph
root
|
_ _ _
| | |
deco | node2
\ |
node1
So I add a deco node to the graph and add the node1 as child of deco
node.
Everything seems ok, my node1 is colored as needed by when I try to
animate the decorator (add an update callback to the uniform , to the
stateset or to the group node with a color change) nothing is updated,
the callback isn't called.
So, is there some restrictions on the update callback call ? A way to
force the update ? Currently, I've found a workaround by rewriting
the traverse function in my decorator node, but I am not very happy
with this solution.
