I am trying to generate a 3D scene with a ball (either a 3D sphere or a 3D particle) moving above a plane. However, the plane often obstructs the view of the ball. Is there a trick to force the ball to always be drawn last? (The ball is the last item in the 3d drawing panel in the view, and the ball is clearly above the plane in the model.) I have attached an example. Thanks!
