You could help yourself if you just add the correct depth attribute to the parent of your node which should be faded out. For example: A is to fade out. P is parent of A, then you do: A->stateattribute->(new osg::Depth(0,1,false)) // or whatever you had before P->addChild(A) P->stateattribute(new osg::Depth()) // or whatever are correct values for proper depth handling. I think this helps. Try it out.
