UE3 - UDK Post process settings wont override.

[macattackk]

Hey, so im trying to change the post process settings based on the player's movement speed. This function is called in a tick and changes smoothly and gradually as the player is attacked.

Specifically im trying to desaturate the scene as the player is slowed down. I have a log in there to check the desaturation and it works perfectly. As the player is slowed down, the desaturation value gradually goes from 0 to 1. It just doesnt actually desaturate the scene. I suppose its something wrong with LocalPlayer(PlayerController(Target.Controller).Pl ayer).OverridePostProcessSettings(NewPPSettings); but ive used this before and it worked.

Anyone know whats going on? Am I not referencing the player's post process desaturation value correctly? how do i log the player's post process desaturation value instead of just my new settings version of it?

function SlowDownPlayer()
    {
        local PostProcessSettings NewPPSettings;

        NewPPSettings = LocalPlayer(PlayerController(Target.Controller).Player).CurrentPPInfo.LastSettings;

        NewPPSettings.bEnableSceneEffect = true;

        if(Target.GroundSpeed > 0)
        {
            Target.GroundSpeed -= 1;
            
            //Set scene desaturation to the Player's movement speed percentage.
            NewPPSettings.Scene_Desaturation = 1 - (Target.GroundSpeed/Target.default.GroundSpeed);

            //Override the Player's post process settings with the augmented one.
            LocalPlayer(PlayerController(Target.Controller).Player).OverridePostProcessSettings(NewPPSettings);

            `log(NewPPSettings.Scene_Desaturation);
        }
    }

Really just guessing but could that be something to do with the PostProcess interpolation duration maybe?

hey nelson thanks for the reply. The problem I had was I was using custom post process chains and it didnt want to override their settings. it only works on a default post process chain i guess. what i did instead was create an uberpostprocesseffect in the chain i was using, then referred to it and modified the desaturation. Overriding post process settings happens slowly anyway. it takes a second for it to load which is what i think you are talking about.

here is the code:

function SlowDownPlayer()
    {
        local PostProcessChain CurrentPPChain;
        local UberPostProcessEffect DieingDesaturation;

        CurrentPPChain = LocalPlayer(PlayerController(Target.Controller).Player).GetPostProcessChain(0);
        DieingDesaturation = UberPostProcessEffect(CurrentPPChain.FindPostProcessEffect('Desaturate'));

        if(Target.GroundSpeed > 0)
        {
            Target.GroundSpeed -= 1;

            //Set scene desaturation to the Player's movement speed percentage.
            DieingDesaturation.SceneDesaturation = 1 - (Target.GroundSpeed/Target.default.GroundSpeed);
        }
