Clear plastic jar one inside the other

[Veronica]

Hi,
i have a big problem with clear plastic transparency. I have to render 3 jars one inside the other but the material of smaller ones it is not clear, as you can see in the image attached.
I also tried with an advanced material and the glass one but it still doesn't work!
Please help me

Under the lighting tab change the setting from Basic to Product, and then also increase the number of ray bounces.

Mmmm I don't find the lighting tab 
It can be for the different version of Keyshot? I have Keyshot 5.0 pro..

Turn on Global Illumination and turn up the Ray bounces to around 10.
