Re: [osg-users] Add ancillary data file to an archive
I see. That's an alternative. The only thing is if I have more than one I have to serialize my collection class as well. The way I did it so far, by making my data items as osg::Nodes, I could add all of them to the root group and I didn't need to serialize the collection. But I'll think about the alternative. Thanks, much helpful!
