Duplicate the mesh that you want to have distortion, go to that NiTriShape > BSShaderPPLightingProperty, put Refraction flag under shader flag, put some number under refraction strength (I usually put 0.05), leave only normal map for that shape and you can also remove alpha, specular, etc, because it's not needed.
You can't have diffuse map and refraction on the same mesh so you have to use separate mesh for refraction.
Oh, that looks so cool! Incredible stuff. Looks like real glass!
Is it possible to make shapes on it, so to speak? I've always had a thing for ribbed glass after I saw some in Half-Life 2. Do you think an effect like this could be achieved?

It would be cool to make the space helmets in Boom to the Moon have this effect as well

(it's a bit too aggresive here)

I didn't discovered it. I first saw it used by XRE author. I just did some tweaks and removed unecessary stuff.
