Weird Glass Distortion with Perpendicular Glass Panels

[martini2]

I have a very weird scenario that i have not encountered before.



Why is the image behind 2 panes of perpendicular glass so shifted?
I tried upping the refraction trace from 5 to 10 on the glass material and the global settings, and it had 0 effect.
Refraction IOR is 1.51.
This is not a natural shift. It happens to some degree from any viewing angle.

Any ideas?

You should make the glass object with a thickness (say 10mm or similar imperial measurement). The glass is thinking that it is very thick right now (distance between railing and facade glass) so the distortion is also big.

User error on my part. I always have thickness in any glass that i make. Usually 1/2" (about 10mm). HOWEVER, when i made the glass door assemblies, i used no thickness panes on each side of a weather strip. That caused the problem. Since they had no thickness, I guess it was calculating the 1/2" thick railing glass as the front of the first pane in the facade glass. Dumb error on my part. Even though i know that glass always needs thickness, thank you very much for helping me to double check myself and my process on this one.
