Vray refraction with flat geometry (windows) - Can't be correct, or?

[rogersandberg]

Hey.

 

I just did a correction to an old interior image where the client wanted a new window design with a 3-glass-window. So I have a window with 3 solid glass pieces that are like 5mm thick and they are distorting the refraction alot so everything outside my window has moved. This can not be physically correct?

I know I can turn down the IOR to 1.0 to get rid of this problem, but glass should be somewhere close to 1,5 right?

It's a bit hard to explain, but take a look at the attachment and you will understand what I'm thinking about.

So my question is, this can not be correct right? If you look thrue a window you dont see any distortion? You just see right thrue it?

 

Would be nice to understand this

Looks right to me. Apologies for the crude drawing. The farther you get from perpendicular, the more the distortion will become apparent.
