Material Refracting back on itself?

[BhMbOb]

Hello, I understand similar questions have been asked before, but I cannot seem to find an answer to this issue (If it’s an actual issue).

The glass material in the image seems to refract back around the corners/through the material when refraction is enabled.
It’s using the typical setup for refraction (lerp between 1/IOR with a fresnel) so I’m unsure what I am doing incorrectly.

Although I’m using a scene capture cube to fake the reflections, using any of the different lighting modes seem to have the same issue.

Any help would be great.

Thanks, Bob

Take a look at this page: Refraction Using Pixel Normal Offset in Unreal Engine | Unreal Engine 5.1 Documentation

Awesome, exactly what I was looking for!
Didn’t even know the existence of Pixel Normal Offset refraction.

Thank you

In Engine 4.15.2 I have same problem with Pixel Normal Offset enabled! The problem was in this option:

It was enabled first (my project had mobile version) and I got strange squeezed results at the middle and far distance from glass:

Of course it should look (and it does with option disabled) like this:
