Hi Lilinx, Have a osg::ref_ptr<osg::Object> Registry::getRefFromObjectCache(std::sring&) method is a reasonable request, now added and checked into svn/trunk. I also added a getRefFromArchiveCache() as well.
For older versions of the OSG you can simply use a ref_ptr<Object> in your own code rather than a C pointer. This still leaves potential for an object to go out of scope while being passed back, but this condition will be a very small window that is unlikely to trip apps up too readily. Robert.
