Hi Sergey,
without example I can only guess what might go wrong,
maybe you need
or some of the nodes have a name, nodemask or userdata or stateset.
all of those could prevent the optimizer from removing the transform.
I also had some trouble getting the optimizer to remove the top node of a
graph, so adding a simple Group on top might also help.
Regards, Laurens.
