Hi, Peter There are some similarities with osg in that regard, osg caches current state to avoid redundant state changes and if you make gl calls yourself you should tell osg state that you changed something, look into osg::State docs about that. Most gl changes in osg done through statesets with setMode(...) which set opengl modes like in glEnable(...)\glDisable(...) and stateattributes. If you need some functionality that not implemented you can create new stateattribute if can fit functionality needed. In case of primitive restart i believe you can enable that with setMode call, and you will need to either write your drawable (or state attribute or drawable draw callback) to be able to set restart index.
