optics2rad

Hi folks,

I'm having trouble with an optics2rad conversion. When I run the conversion
script, it simply spits back the glass description instead of nice cleaned
up BRTDfunc. It works fine with other glass assemblies, so I think it's
specific to this description (copied below).

If the front and back reflectance values are close, as in this example,
does optics2rad simply say "don't worry about it, the RGB glass default is
close enough"?

Thanks for any insights - here's the export from Optics 6:

Law of the universe - once you decide to email the list, you'll figure it
out, and it will likely be a rookie mistake.

The outside pane of glass was flipped in Optics, and the low-e coating was
on surface 1. optics2rad didn't like that, and thankfully refused to make a
bad material description.
