Hi,i made this simple scene: a red light source through a projector(a small
prism) , a large box to define an interior and a media, and finally a mirror
(define by points of spline) and a cylinder for test the reflection. I have also
2 camera, by the ortographic camera, as you can see rendering the scene, are
visible the correct rays of light of a source light (thanks to interior inside
box) but i don't understand why i dont' see the rays of light reflected by the
mirror. While if i active the 'camera behind' you can see that the photons
reflacted on a cylinder correctly!
How can i do to show the rays of light reflected by the mirror like the rays
that hits the mirror?
I posted a code of scene.
