Hi Robert, unfortunately i have to use older version of osg because currenty i am fixing bugs of one our simulators which is developed in 2007and 2008. we implemented this simulator in delta3D 1.4 which uses the older version of osg. i want to upgrade this system to the newer versions but i am afraid of getting many errors. there are many changes between versions like producer.
that's why i am trying to find some backward compatible solution...
