Are display lists active in your scene? if so, maybe a dirtyDisplayList() call might be required on the affected drawables.
drawable->dirtyDisplayList() As far as I know display lists are still the default in OSG, unless you explicitly disable them on geometry objects (and possibly enable vertex buffer objects instead, for performance reasons) the corresponding API calls on drawables would be drawable->setUseDisplayList( false ) drawable->setUseVertexBufferObjects( true ) you could use a visitor right after loading the scene to switch off display lists and enabling vertex buffer objects instead.
