thank you for your reply,Jeff.
I watched your video,and found that using vray maybe the real solution.I wonder whether this feature is fixed in the later version,as I noticed you were using max 2009.
For I'm a maya user,I got a further test in maya 2012 and found some interesting:a reverse reasult with 3dmax.
I posted a test here,and looking forward to your reply.
