Hi, Thanks for clear things up for me, it does help alot.

My scene are contains numbers of models which consist of multiple parts. Although each part will always be in the same position relative to each others, I can't really merge them to one osg::Geometry. Because they need to be able to change colour independently on run time. I just changed my code to share stateset, and it does help quit a bit. Now I am thinking about to create one huge static vertices array which will be used by all the geometry in the scene with correct indexing. Do you think this approach will help? or it might make the matter worse? Thanks again for your help!
