If it's rendered with both orientations then wouldn't you just disable the face culling? > The only thing one could do would be to duplicate the geometry... > which is not really an optimization. It all depends upon how much geometry you have to duplicate. What we a talking about here is a very specialist requirement, and you are proposing a solution that require intrusive changes to a number of classes and introduces inconsistencies with how OSG state is a managed. For me it's way too intrusive and lacking in general benefits for me to consider as inclusion in the core OSG. I would still like to see the problem you are trying to address resolved, but it'll have to be something that you can do separately from the core OSG.
