I want to render thin bumpy glass with refraction. But it offsets too much(look at the black frame of the glass). Looks thick.

How to do thin glass refraction properly? Or is it possible to exclude object(e.g. the black frame) from refraction?

I would look into the Refraction Depth Bias parameter of the material you are using. It is mentioned in the Unreal Engine documentation.
