[Radiance-general] trans

[Greg Ward]

Hi Martin,

I'm not sure I understand your question.  Could you restate it more  
clearly?

Are you speaking of the rpict/rtrace -i+ rendering option?  In this  
case, trans materials will be ignored, treated as if they were not  
there at all, regardless of the real arguments.  The same is true for  
dielectric and glass materials.  This is designed to avoid the  
confusing situation where you see the irradiance arriving at a window  
rather than the irradiance on the objects visible through it.
