Hello. I’m developing a game and I want to make a shelter. This shelter is 40% translucent. I want it some blurry like in the picture. Like an icy glass. How can I do it in Material Editor or Blueprint?
You could do something similar in a material. No need for Blueprints here.
This thread has a good starting point: Frosted Glass ? - Rendering - Epic Developer Community Forums
With my own tests I’ve been able to get good results as well using that.
This could be extended further using more material work for a more desired work.
The one thing that you will notice with this though is that there is a aliasing/blur effect that can happen with the objects behind the material. This is just a limitation of this kind of setup and anti-aliasing.
There may be other ways to get a smoother result, but this is a good starting point none-the-less. 
Thanks!

Yes , but I don’t want distortion on the vision. Just blur effect. Can it be possible?
saw this but does not help much as there is no node setup (at end of topic) So Blurred glass material is impossible in Unreal Engine 4? - Rendering - Unreal Engine Forums
Yes, in my replies to the same thread I posted a node version that uses scene texture to do the blur. It is fairly expensive though so fair warning. Try to use the least steps as possible.
