I'm using RTTPicker for picking nodes, and it's working fine with most featurenodes, except ones with modelsymbol (and no other polygon/linesymbol). For example i have area filled with trees, and i can't pick it. If i set some linesymbol/polygonsymbol to my style, i can pick it if i click on polygon/line, but not model.
Also some observersion: if i use this features/styles within FeatureModelLayer instead of making them FeatureNode, i can pick them. Maybe i need to set some property to featurenode?
From code. Yes, i know about tagNode. If I didn’t do that, I wouldn’t be able to pick other featurenodes (or same nodes with added polygon/linesymbol). But my point is the problem only with featurenodes with modelsymbol and without line/polygon symbols.
So assume i have style with altitudesymbol and modelsymbol and feature with polygon geometry, so this models would fill my polygon (or just single point for single model). In this case, i can't pick (by clicking on model) featurenodes created with this style/feature. If i add a polygon/line symbol, i can pick it (by clicking on polygon/line, not model). Also, in this case, basic shader for "picked" indication (like in osgearth_pick application) only works for polygon/lines and not for models.
