How do I shift the Bulge effect?

So I want to create a sort of background effect that "bends" near the player. My first idea was to use the Bulge effect with a small radius and a negative scale, but then I found out I cannot set the position of the Bulge.

Is there any way to do this or recreate the effect, maybe using meshes or something?

Here is an example screenshot of what I want to achieve.

See my comment in this post:
