Internally osg::State maintains a global_default_attribute for each of these stacks and calls this when the stack is newly emptied when the last stateattribute of that type of popped and the current state applied, the method osg::State::applyGlobalDefaultAttribute(AtrtributeStack&) does the actual work so go have a look it it's implementation. The mode stacks also have a similar global_default_value member variable that tracks what to apply when all the modes of given type of popped. What is missing for you is a convenience method that gets all these defaults, or applies these. You could write one and submit it for inclusion in the OSG, or look to create your won StateSet based on these global defaults embedded in osg::State. Alternatively just apply the StateSet to make sure the modes and attributes you care about are set to a value that your OpenGL code requires - this is normally what one does in this instance. Robert.
