Hey Roger,
I really have no clue why your model isn't showing up. It's got
something to do with the 2D woman you added to the Arc de Trioumphe
scene. If you download the arc and run it through kmzcleanup it will
load and render just fine. But the test.dae document you sent has the
little woman in it and it doesn't load.

I noticed something weird when loading this in Google Earth (which it
does load fine in Earth). When loading the arc by itself the bounding
box GE calculates is snug against the geometry, which is to be expected.
When loading the test scene with the girl and the arc the bounds are
HUGE compared to the arc and girl. Maybe there are some stray vertices
causing that to happen. I really don't know. And I don't know why it's
not showing in osgviewer, it may be related, maybe not. But its
definatly got something to do with the added 2D woman figure.
