My application uses various extruded versions of CircleNode, RectangleNode, etc. In the migration from 2.8 to 3.0 the outlines that were normally drawn for these shapes have disappeared. I haven't changed the outline setting in the PolygonSymbol portion of the style. Any ideas as to why this is happening?
The extruded ellipse and extruded line shapes defined in the annotations.earth file appear to have outlines when I run the example on my machine. I will take a closer look at the parsing of that file and the resulting geometry creation in the osgEarth source to be sure my code matches whatever that is doing.
