Hi Carl, It sounds like you are most of the way there, osg::State maintains the list of current state that has been applied so you just need to get the current uniform set from the osg::State object. The stumbling block is that is presently any accessors for the internal data structers and these data structurs are all defined in the protected scope of osg::State - this is dileberate as the internal implementations details of a complex class like osg::State is best kept protected so that any changes in internal API/data strucutres won't effect the build of 3rd party applicatons.
What you could do is add public accessesors to get the get current uniform state, these methods could worry about the internal implementation details so the internal structures won't need to be moved into the public scope.
