Hi Art,
Sorry. Yes, I simply add an empty shader on the proxy node containing
the cow and it works.
Like Robert says it is a clue to figure out where the problem come from.
I will investigate more deeper in this way and post a submission if I
find the origin of the problem.

Have you tried, what I have proposed before?

Hi David,
I turn off the optimizer in osgviewer and the problem stays
the same.
Thanks for your help.

Stephane,
Have you tried running with no optimizer? A while ago
I dimly remember
encountering something similar with the optimiser
doing funny things
with empty nodes that had state changes...
Dave
