Papervision vs. CS4 3D

Hi! I’m trying to build a spinning cube with the built-in cs4 AS3 3D features, and facing a simple z-sorting problem without getting any answer. So I’m thinking it’s not so simple.

So, in the end, what do you think about new features? Provided that I only do simple things, not 3D modeling at all, from an AS3 point of view, or perspective (yes, I’m playing wiith words :grin:) should I continue using Papervision? Isn’t it a little smarter? What is better?
