I must say it looks great!
But i still miss a little refraction. Maybe just try so set it REALY low, like 1.01?
It might give you the right effect.
I don't know where you've got that information, but 1.07 is way too low. 1.5 is a good for ordinary glass.
>> I got that from one of my older posts, but I also think even 1.07 gives to much refraction.
Especially in round glass objects.
