Fwd: [PD] perspective in gem

[vade]

I think youd have to set your gemheads to render sequentially, and  
using their triggered output to reposition the camera accordingly,

ie: gemhead 1 position camera, render cube, , gemhead 2, reposition  
camera, render cube2, etc

I thought you could change your  lens angle, but I cant seem to find  
the functionality...
