i have 4 buttons on screen that right now are just white transparent circles like this ![alt text][1]
i would like to have them blurred like the blurring in ios7. ive tried multiple shaders and have also tried the image effects that come with unity pro but none of them work.
this needs to work on mobile so it needs to be done well but also efficiently. any ideas?
