Hi,
In my scene graph I have root node and I am doing deletion/addition of nodes
in scenegraph at run time from a different thread than main thread. These nodes
are simple textured quads and are having dynamic textures. Data variance of
root node as well as these child nodes is set to DYNAMIC.
My Osg::Viewer threading model is set to SingleThreaded.
What I found from previous posts is that multi-threading should not be the
issue as long as we are setting data variance to DYNAMIC.
I was trying to reproduce this crash after setting osg::NotifyLevel to INFO. I
will post more details as oon as i get some log.
meanwhile the call stack i am getting is as follows
