Yes I did. To find out how "complicated" it is to get good glass :)

Indeed, it isn't. 

Probably I have to hack BB's material converter to make it simpler. Problem is, this part is heavy complicated programed. Will see what I can do today.

For the moment, find any occurence of Poser converted glas material.

After the line:
MakeNamedMaterial ""

insert:
 "string type" ["glass"]

 "float index" [1.52]

If you have a single-sided glass model, insert a third line:
 "bool architectural" ["true"]

For best results use double-sided glas. Or you have to use "glass2" and to play with "volumes". But this is another complicated Lux-story ;)
