    Hello Alain:

      First of all thanks. I mean "Glasses", specific, architectural or
furniture glasses.


As I said to Christian and JR, I want to get a good material for a tempered
glass dining table. I tested with different types of F_Glass, and do not get the
result I want. I tried to include the variation of Interior glass, but can not
get to run the file.

This is an example of how the material I have currently, is the closest thing
I've gotten what I need, but are, for my taste, too much reflection. Could you
give me some advice?.




#declare Cristal_Mesa = texture {

    pigment { color rgbf <0.05,0.05,0.05,0.40>}

    finish { F_Glass5 }

}


Thank you again.

Good Day
