[Papervision3D] Can't seem to figure out Cameras

[Javier España | javierespana.com]

Yeah, when I go to the 3dsmax file the object is in 0,0,0

I've used camera.target, and it locks on the object, but the object is above
the center of the camera, it isn't at the same level to put it someway...

Why can this happen? I can manually move the camera on the y axis to focus
better on the object, but that's a manual way to do it, any other way?

I'll print this :D thanks
