I imagine you had tried http://projects.blender.org/projects/osgexport/
I tested it with blender 2.4.1 and was able to export the fiat Stilo
model found at http://puudeli.zoo-gate.fi/~haba/3d/
with her texture.
I' ve tried your stopsign, but it does not show textures in blender and
as well the texture did not came out in .osg
hope it helps

Here is a follow-up on my quest to find a art path that works with OSG, most
recently with Blender.
Although my previous conclusion that OBJ is the only format which produces
correct geometry, my excitement was dimmed when i found out that Blender's
OBJ export flattens all transforms, effectively mashing a whole complex
scene into a single rigid object. (In fact, i believe it has no choice,
because OBJ can't represent an object's position). Furthermore, there is
the classic axis problem: Blender has Z up, it writes an OBJ with Z up, OSG
is Z up, yet, the model is not right-side up because OSG thinks OBJ is Y up.
Blender's COLLADA export does not flatten transforms (hooray!) but then i
found additional trouble with the exporter, including missing materials and
strange normals behavior causing missing faces. I'm assuming the exporter
is at fault on the normals, although it could be some interaction of the
exporter and importer.
I've updated http://vterrain.org/Implementation/ArtPath/blender-osg.html
To summarize: I'm back to concluding there's no sufficiently functional way
(yet) to get models from Blender to OSG. After giving up on 3DSMAX/OSGExp
for reasons described before, this is really depressing. I'm at a situation
of no art path.

Subject: [osg-users] Blender to OSG (was COLLADA plugin for
OSG onSourceForge)
I spent this evening building the OSG COLLADA plugin and
starting to test it. [..]
My reason for doing this is... A bit of a long story :)
Basically, 3DSMAX has just been too much grief over the
years. It's terribly expensive, cracked versions are
unreliable, OSGExp is hard to build and not well supported,
and materials rarely look the same in MAX and OSG.
Hence, i'm evaluating the 'Blender' free modeller.
(http://www.blender.org/)
My first impression is that Blender is great! Besides the
goodness of being cross-platform and open-source, it's a
downright pleasant and easy modelling tool. So, the
challenge becomes, how does one get models from Blender to OSG?
My initial testing results are here:
http://vterrain.org/Implementation/ArtPath/blender-osg.html
Executive summary: COLLADA looks promising, but not quite
there yet. Good old Wavefront OBJ worked the best of all
possible formats.
