That requires render to texture. Its when you render the view's output into a texture so you can manipulate it, etc. You cannot manipulate (blur, etc) a view directly.

If you do not want to use render to texture, AFAIK the effect is not possible.

But I don't actually want a refraction method at all, I want something that blurs what was already drawn (sorted like how transparent entities are sorted since you can see through it), kind of like how on vista the stuff behind title bars are blurred, only it jiggles a little.


If you want heat haze like this:

you will need a refraction shader. You simply use a normal map which simulates refraction of the image behind it (you render it to a texture so the shader knows what is behind it).

If you even want to blur something, you still need render to texture ;\)
