I know how to create blurred-reflections by averaging
a texture which has same pigment/finish, but randomly
different normals to get more "samples" for the normal-
based-reflection.
Now, is there a possibility to do so with refractions as well?
Aside from giving the surface a normal I mean.

What's wrong with giving the surface a normal to get blurred
refractions?

The specular highlights and reflections will get blurred as well,
don't they?
I want just blurred refractions, but with the possibility for
"normal" reflection...

this is not too photorealistic, but maybe use layer textures ? one without
blur for reflection and second with no reflecion, with normal - fo
refraction

Hmm... Why didn't I think of that? I'll try it. Thanks
