Hi,

I'm a new user on povray and i am looking for using mirror.
In fact, i would like to use an object like a mirror, and for that, i've 
used the declaration "Mirror" from the include "finish.inc" bundled with 
povray.

My problem is that the light don't reflect on the mirror. I can see 
reflected objects in the mirror, but with a spotlight in the direction 
of the mirror, the light cone is not reflected :


light source
     V  |
      \ |
       \|
       /|
      / |
     /  |
    V   | <= mirror
------------------------<= ground
    ^
    |
    not light on the ground.

Is it possible to do that ?

Thank you in advance.
Nicolas.

Yes, you need to use photons. Section 3.5.3 of the documentation should
make everything clear.
