    Hello,
    Im searching for a way to implement a special Blur shader.
    I want a sharp image around a variable XY-Point on the screen and it gets unsharp when you move away from this point.
    (I dont want to implement depth of field or a radial blur shader)

    How would you do that?

    It should look like this:

    Your best bet is probably to perform the blur, and then use a mask to blend between the blurred result and the original. You won't get the perfect transition apparent in your pictures, but that's about the best you can do without things getting really expensive or really fancy.

    Try looking for how to do a full screen bokeh effect, the DOF in the Unity Pro package is capable of achieving this effect so if you have access or haven't burned your trial yet, have a look , this is pretty much what you are trying to implement. God speed.
