Thanks Robert, I was thinking to do something like this (but will look in your pointed direction as well).
osg::State & state = *renderInfo.getState(); osg::ref_ptr< osg::StateSet > stateSet = new osg::StateSet(); state.captureCurrentState( *stateSet ); state.disableAllVertexArrays(); state.dirtyAllVertexArrays(); GL Drawing state.apply(); The GL code usee glew and some (really few) calls for reseting some states, but my intension was not to include glew in the project and have it all osg clean.
