I seem to have contracted chronic Radial Blur

[Bennick]

Okay so, I have a function where looking at something causes some sanity damage, and in true Amnesia style, I want it to be accompanied by the Radial Blur effect and a sound effect. When I try to do it though, it stays on my screen and won't go away until I make it to the next map. How do I fade it in and then fade it out?

The two commands were in the function something like this:

FadeRadialBlurTo(1.0f, 0.5f);
FadeIn(1.0f);

What should I do for this to work? is this some kind of timer function?
