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.

Hi Vincent,
I've already rewrited the traverse function of my decorator to allow the
updating of my shader but I don't understand why the update callback
isn't called automatically.
If the "node1" has only one parent, the "decorator" node, the update
callback works but if the node1 has two parents, the root and the
decorator nodes, the update callback isn't called. Why ?

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.
