Hi Dan, I'm not at a point where I can easily switch over to thinking about OSG code written by others so rather than jump it right now I'll ask a simple question that might help point you in a direction worthy of investigation.
FYI, I'm not the author of the OpenFlight plugin so am in the same boat as yourself when it comes to working out what it does, what is intended, what might be a bug etc. Each time I'm called in to fix something in this plugin I learn a bit more... but still lots more to learn. I don't personally recall working with a flt::Registry::instance() local cache so it's a new bit of OpenFlight plugin to me. I'm a bit surprised it's there as osgDB has it's own object cache, so I'd wonder what the motivation was behind the local cache and whether it's really necessary. Could it be rewritten to use the osgDB's object cache? Robert.
