Hi Bob, All you need to do is call dirty on the osg::Image attached to the Texture and the OSG will automatically do the subloading for you, you don't need to do anything. Performance is typically very good. With a non power of two texture take care to use a TextureRectangle of use Non Power of Two Texture support in Texture2D - to do this you'll need to disable the resize non power of two texture hint in osg::Texture.
