how to enable/disable a postprocess at certain time ?

Hi everybody
i wanna disable/enable an image effect like blur at certain time .
how it can be done ?

Well if your image effect is a component attached to your camera… do something like this…

Camera.mainCamera.GetComponent<Blur>().enabled = false;

Where ‘Blur’ is the name of your image effect attached to the camera.

i get this error:
The type or namespace name `Blur’ could not be found. Are you missing an assembly reference?
