Thanks for the quick response...

Did this:
   render->getSceneView(0)->setCullVisitor(cv);
   render->getSceneView(1)->setCullVisitor(cv);

and now I'm getting:
Warning:createOrReuseRenderLeaf() skipping multiply refrenced entry.
Warning:createOrReuseRenderLeaf() skipping multiply refrenced entry.
Warning:createOrReuseRenderLeaf() skipping multiply refrenced entry.
Warning:createOrReuseRenderLeaf() skipping multiply refrenced entry.

Subject: Re: [osg-users] Setting CullVisitor

Hi Paul,

> Why do I have multiple SceneViews? 

There are always two SceneViews if you're using multithreading - they're used 
on alternating frames as you've seen. Just set your CullVisitor for both, or a 
separate instance of your CullVisitor for each instance.

Whenever I've had to change something on SceneView instances, I had to do it on 
both instances. I expect if your CullVisitor has some local state, you'd have 
to use two separate instances, one for each SceneView, so that threading works 
correctly and doesn't try to modify data that's being read in another thread.

You could just override the traverse() method of your node type, that's how I 
normally do it. It keeps changes local to the overridden node class instead of 
propagating changes to other parts of the app.

  void traverse(osg::NodeVisitor& nv)
  {
      if (nv.getVisitorType() == osg::NodeVisitor::CULL_VISITOR)
      {
          osgUtil::CullVisitor* cv =
              dynamic_cast<osgUtil::CullVisitor*>(&nv);

          // ...
      }
      osg::Node::traverse(nv);  // call base class version.
      // (replace Node by whatever the base class of your overridden
      //  node type is)
  }

Hope this helps,

J-S
