Thanks for the reply. I tried your suggestions:
// Cleaning scene
while (scene->getNChildren()>0)
{
OSG::beginEditCP( scene );
scene->subChild(0);
OSG::endEditCP( scene );
}
after it I add a node in the scene. My goal is to clean up the scene and
then add a single node alone... but when I use the code chunk you have
suggested, it crashes just at the rendering of the scene (
scenemanager->redraw() ). When I take the chunk off, it works perfectly,
only of course, with many nodes within the scene.... Any one has an ideia of
what is going on?
