Hi Matt,
SharedStateManager is what you want. I didn't have luck improving performance with it, but you can check it out. I believe the DatabasePager shares the states when data is paged in if the SharedStateManager exists. (I don't think it is initialized by default). You have to call: osgDB::Registry::instance()->getOrCreateSharedStateManager(); to create it, and then it should run from then on. Look inside the osgDB::DatabasePager code for sharedState. Also, osgDB::SharedStateManager.cpp I think it is pretty time consuming, though, so it may not work for you. I think you'll get a decrease in memory usage, but also a decrease in performance. Its easy enough to try though. (Just add the one line above before you load any models). _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Franklin Sent: Sunday, September 16, 2007 4:25 AM To: [email protected] Subject: [osg-users] Sharing statesets across files Is there a way of including a proxy stateset node or referencing a stateset stored in another file? I am trying to split up a single model into smaller pagable chunks. However, my original model makes significant use of shared statesets to maximise reuse of textures. When I break up my model each leaf node includes its own copy of the shared stateset. The total disk space used by the resulting fragments is a factor of ten larger than the original file. This in itself is not a problem but the resulting texture memory usage is also a factor of ten larger as a result of the lack of reuse. Thanks in advance, Matt
