I'm using the ArcGIS API for JavaScript 4.20. I'm adding point graphics and text graphics to a 3D scene view, using GraphicsLayer and TextSymbol. It's working well. But the text graphics are always billboarded, even if I use the on-the-ground mode for the graphics layer. Point graphics honor the mode, displaying draped if the mode is on-the-ground and billboarded if the mode is relative-to-scene.
Is there a way to get text graphics to drape on the 3D scene instead of billboarding?
