RadTrandMaterial Info

I am trying to model RadTrandMaterial for textile shading for a skylight. I am trying to understand the input requirements for this component. It seems "http://radiance-online.org/community/workshops/2010-freiburg/PDF/DavidMead.pdf’ could help to understand the requirements better but I could not find the document. Any pointers/insight would be appreciated in this direction.​

thank you,


Somehow, I am finally able to get a copy of the PDF.
