I am trying to use the pp_lens.fx effect. It works, but it seems too strong for what I want. Is it possible to make the effect slightly less strong? The only parameters offered are the x and y coordinates for the effect, I don't see anything about the strength of the effect.

Oops, I think I found it.



This seems to determine the strength. Changing 0.1 to a lower value, like 0.05 makes the effect less obvious.
