Changing post processing with code in unity doesn't fully work

Question

I want to change all properties of the lens distortion in my post process profile but can't. I can change the intensity and scale but not the center and multiplier values. This is my code:


using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Rendering.PostProcessing;

public class Mastergame : MonoBehaviour
{
    public PostProcessVolume volume;
    LensDistortion lensdistortion;

    void Start()
    {
        lensdistortion = ScriptableObject.CreateInstance<LensDistortion>();
        lensdistortion.enabled.Override(true);
        lensdistortion.intensity.Override(1f);
        volume = PostProcessManager.instance.QuickVolume(gameObject.layer, 100f, lensdistortion);

    }

    void Update()
    {

        lensdistortion.intensity.value = Mathf.Sin(Time.realtimeSinceStartup) * 90f;
        lensdistortion.center.value = new Vector2(5f, 5f);
        lensdistortion.xMultiplier.value = 5f;
    }
}

I have also tried the UnityEngine.Rendering.Universal library quickly but it didn't work either.

These are my errors:

Assets\Mastergame.cs(23,24): error CS1061: 'LensDistortion' does not contain a definition for 'center' and no accessible extension method 'center' accepting a first argument of type 'LensDistortion' could be found (are you missing a using directive or an assembly reference?)

and Assets\Mastergame.cs(24,24): error CS1061: 'LensDistortion' does not contain a definition for 'xMultiplier' and no accessible extension method 'xMultiplier' accepting a first argument of type 'LensDistortion' could be found (are you missing a using directive or an assembly reference?)

From what I see in the LensDistortion API documentation, I think you need the following:

lensdistortion.centerX.value = 5f;
lensdistortion.centerY.value = 5f;
lensdistortion.intensityX.value = 5f;

The fact that some of the property changes were working as expected, but some of them were giving what effectively looked like syntax errors was a very useful clue. That suggested to me that there was an API supporting at least some of this, but that it was likely either incomplete or inconsistent with regards how the Inspector refers to Lens Distortion. Most of the documentation I found was for the Inspector; searching specifically for the API lead me to the solution.
