Blur only the top and bottom of the screen

I need to simulate an effect similar to what creates. As a small step towards accomplishing it i need to say only the top and bottom 40% of the screen will be blurred, while keeping the center 20% crystal clear.

I thought maybe i could have a plane that blurs whats behind it, but i couldnt find out how to do that either, so any help at all with this issue would be great :slight_smile:

Do you have Unity Pro? This could be done fairly easily with Pro, see these two unityAnswers posts for more info, and this Unity documentation about blurring images.
