[Radiance-general] gloss specifications to roughness/specularity

[Gregory J. Ward]

Hi Jack,

I don't want to discourage you from reading this paper, because it's  
really nice, but I don't think it will help in getting meaningful  
values from gloss measurements.  I almost mentioned it myself in my  
reply, but was too rushed to go look up the reference.

As for material type, you are better off using "metal" if the  
metallic paint has a strong color to it, as they usually do.  If you  
want to see the clear coat as well, you can try a mixfunc between  
metal and plastic.

-Greg
