Yes You did but I don't give up easy. It was exciting challange to force 1.7.1 to do this. As I said wizard "common" glass was teribble so I play a little with bump and anizotropy on roughness 0 (zero) to achieve this picture.
I think "my" glass is not so bad, but I am not so "pro" to tell where is mistake in light propagation. I just like it "as it is".

NOO WAY !! I have to examine that, because I don't know why it works like that.

GREAT! thanks in advance!

Just got it. I misunderstood before. I thought second layer is just for reflection (opaque in additive mode). It is perfect clear now! Thanks again.
I think You have to write manual Tom, with at least 50 pages of how to do materials. Then gallery on this forum would be 20 times bigger than now.
