When running with my proposed changes, I see some interesting warning messages,
leading me to suspect why they were originally set to INFO level.
However that seems to be masking a problem. Once we have loaded the model, we
try to drop it back out to an osg file, which results in several failures to
load dynamic libraries. These are caused because the filename does not match
the dll name correctly.
The problem comes about because of
Code:
// first try the standard nodekit library.
std::string nodeKitLibraryName =
createLibraryNameForNodeKit(libraryName);
if (loadLibrary(nodeKitLibraryName)==LOADED) return writeObject(obj,fw);
// otherwise try the osgdb_ plugin library.
std::string pluginLibraryName =
createLibraryNameForExtension(libraryName);
if (loadLibrary(pluginLibraryName)==LOADED) return writeObject(obj,fw);
which gets called once for every node we want to output? The library isn't
loaded multiple times, but we try to load it multiple times which seems very
inefficient. I'm trying to think of some way we could short circuit the call
earlier and detect it is already loaded but so far I haven't got a solution.
The Log messages I get are:

This is for a rather small model too.

For the moment, how about we don't make the change and I'll try to come up with
something better.
