[Radiance-general] Trans material

[Greg Ward]

Hi Martin,

Any trans materials will be ignored if you use the -i rendering option.  If you didn't use -i+, then you shouldn't see through a trans with Ts=0.

Between layers of trans materials with both diffuse reflection and transmission, many interreflected rays will be traced.

However, I am simulating a model with three layers of Trans material and I would expect that your view from inside and outwards even when considering illuminance levels would be diffused (being filtered through three layers) ? Maybe I am missing something?
