i´m afraid i answered the mail too fast
after setting the ---->>>>
viewer.getUpdateVisitor()->setTraversalMode(osg::NodeVisitor::TRAVERSE_ACTIVE_CHILDREN);
now the problem is that it´s always calling the update callback of the LOD´s
first child, none of the others, even when i know for sure that other LOD child
is being the active one cause i see the LOD changing in the rendered scene.
well, i´ve searched for an error in my code for more than an hour and i´ve
found nothing. i guess is my fault and i have a bug somewhere and i´ll keep on
searching but, just for being sure i have to ask.
According to theory, only the LOD´s visible children update call back should be
called, isn´t it????
