Hello There,

I am trying to render a scene, whrere a laser beam is refracted by some objects,
but it just does not work. I found a similar question here

web.487989b0797036a91a8107a20@news.povray.org

and the scene mentioned there actually works. Mine still won't, so what is wrong
with it? Thank you in advance for your help!
