Post Process - how to change saturation via blueprints

I’m making a game where I need the character’s proximity to a fire to increase the saturation and cap at 1 (meaning normal vision). The saturation will then decrease slowly the further the character is away from the fire.

What I’ve come up with so far: https://puu.sh/is8kt/a2645544b2.jpg

The “Left Shift” was created for debugging purposes.

The TriggerVolume1 is currently taking place of a fire particle system i’ll make in a bit once this is done.

The “PostProcessVolume” is the volume in my level

So to recap, the problem is I’m not sure how I can use the Post Process Component with an integer value…

Any solutions could you please explain them as basically as possible, images would be great :slight_smile:

I have managed to do that in my player pawn by using this, hope it helps (This actually fades the screen to grey).
