Hi Boto, Have you looked to osgDB::Registry::setReadFileCallback ? Another way to achieve what you want can be to make a plugin for your packed file and use encoded strings as files names to know wich file to get from your pack, ie : cow.osg|mypack.pack With such a file name, your plugin will know that it needs the pack "mypack.pack", and that it needs to load the cow.osg file from it. This way you can even pass to the OSG plugin a custom std::stream which can read into your pack system.
Hopes this helps !
