I just started learn papervision. I am trying to do a reflection map on the plane.  
The result is i can only see the model on stage, but i can’t see any reflection map on it.  
Is there anyone who can help?

The following is my codes

}

I downloaded the PlaneReflection.as class file at [http://blog.zupko.info/?p=156](http://blog.zupko.info/?p=156).
