Feature with ModelSymbol not displayed

[sebalaig]

Hello,

I'm trying to display an OSG geode (in an osg file "arrow.osg") in my map using the Feature and ModelSymbol tools, but this is not working: nothing is visible. I'm missing something but I cannot figure out what's wrong..

Here is my code:

        osgEarth::Style style;
        ModelSymbol* modelSymbol = style.getOrCreate<ModelSymbol>();
        auto* tmp= osgDB::readFile<osg::Geode>("arrow.osg");
        modelSymbol->setModel(tmp);
        modelSymbol->heading() = 50;
        modelSymbol->scale()   = 2;
        modelSymbol->placement() = InstanceSymbol::PLACEMENT_VERTEX;
        modelSymbol->autoScale() = true;

        osg::ref_ptr<osgEarth::PointSet> point = new osgEarth::PointSet(1);
        point->push_back(2.35, 48.85, 50);

        osg::ref_ptr<Feature> feature = new Feature(point, geoSRS, style);
        osg::ref_ptr<FeatureNode> featureNode = new FeatureNode(feature);
        featureNode->setMapNode(mapNode);
        
        mapNode->addChild(featureNode);

That code was ok using previous osgearth version (2.7) but fails with v3.3.

I tested by using osg::Transform to rotate/scale and GeoTransform to set the model position => it ok.

But in my context, I'm in an overload of FeatureSource::createFeatureCursorImplementation, so I have to build features, and it would be easier/cleaner to use osgearth API instead of OSG one's IMHO.

Thank you in advance for your help.

Notice: writing this is ok:

            modelSymbol->url()->setLiteral("arrow.osg");

Any idea/suggestion ? Is the in-memory not supported anymore ? I have many geometries to display, so writing them to disk is not an option :/
Thank you in advance for you help.

It looks like a bug fixed in osgearth 3.4, a duplicate of #2299. I will update to v3.4 and recheck that.

The patch of #2299 is not relevant on FeatureSource (#2312 (comment))
