Change ambient Intensity on Trigger Enter

Hi everyone,

I'm trying to build a scene where ambient Intensity is '0' at first - to have everything kind of Black and white. After a while - the player picks an object that should set the intensity to 1.

Something like this basically (its not the entire code, but the jest of it..):

void Awake(){

RenderSettings.ambientIntensity = 0;

}

void OnTriggerEnter(Collider other)

{ RenderSettings.ambientIntensity = 1;

}

Now when I start - the intensity is indeed 0. But when the trigger is on - the intensity doesn't revert back to 1. (though through - "Debug.Log("ambientIntensity") - I can see its 1..)

Any ideas? might be that ambientIntensity can't be modified in game, only once at game start?

Thanks!
