Hi, I'm still struggling to correctly draw simple scenes using fresnel
reflection and photons (code below). Any idea why this code doesnt show the box?
with ior = 5 I expected to see the box being about 0.44 intensity

thanks
Stu


#default {finish {ambient 0 diffuse 0}}

global_settings{assumed_gamma 1 max_trace_level 50 photons{spacing 0.001}}
camera{orthographic location <0,0,1> look_at <0,0,0> angle 90}
light_source{<0,0,2>,1 parallel point_at 0}
box{<-.5,-.5,0.1> <.5,.5,0> pigment{rgb 1} finish{reflection{0,1 fresnel}
conserve_energy} interior{ior 5.0} photons{target reflection on refraction on}}
