Hi Linh, FYI, osgProducer is still available, its up on the openscenegraph.org server:
http://www.openscenegraph.org/projects/Producer As for support for 1.2, Paul Martz and Bob Kuehne have professional support in place for users who need to work with 1.2, myself I'm focused on developing and supporting 2.x. Personally I'd recommend moving to OSG-2.4, including migrating to osgViewer - first up lots and lots and lots of bugs have been fixed, second it's has plenty of useful features over 1.2, including a far more capable VirtualPlanetBuilder project, third you support is far cheaper for all concerned, including you. Rather than keeping putting off upgrading please remember the scene graph API in 2.x is fundamentally the same as in 1.x, just tweaks and additions to improve things, porting scene graph code across should be straight forward and this is generally what users fine. Porting osgProducer::Viewer based apps to osgViewer::Viewer based one is a little more taxing but generally pretty straight forward. If your code has lots of Producer code in it then this will take long to refactor. Robert.
