Changing Materials dynamically isn't working

Unity Engine
1

I have a prefab for my main character that has the player character as a child. The player character as the biped skeleton and a skinnedmesh renderer object as children.

The SkinnedMesh object has 4 materials attached.
One the highest parent I have added a ClothesManager Class that manages when this changes that looks like this:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class MageClothesManager : MonoBehaviour {


    public GameObject WizardObject;

    [Header("Body Parts Colours")]
    public GameManager.Colours HatColour;
    public GameManager.Colours CapeColour;
    public GameManager.Colours LeftHandColour;
    public GameManager.Colours RightHandColour;

    [Header("Body Parts")]
    public GameManager.BodyParts FocusedBodyPart;

    [Header("Material References")]
    public Material GreenHatMat;
    public Material RedHatMat;
    public Material BlueHatMat;
    public Material YellowHatMat;
    public Material GreenBodyMat;
    public Material RedBodyMat;
    public Material BlueBodyMat;
    public Material YellowBodyMat;
    public Material GreenLeftHandMat;
    public Material RedLeftHandMat;
    public Material BlueLeftHandMat;
    public Material YellowLeftHandMat;
    public Material GreenRightHandMat;
    public Material RedRightHandMat;
    public Material BlueRightHandMat;
    public Material YellowRightHandMat;


    void OnEnable()
    {
        EventManager.HatChange += ChangeHat;
        EventManager.CapeChange += ChangeCape;
        EventManager.LeftHandChange += ChangeLeftHand;
        EventManager.RightHandChange += ChangeRightHand;
        EventManager.FocusBodyPartChange += changeFocus;
    }
   
    void OnDisable()
    {
        EventManager.HatChange -= ChangeHat;
        EventManager.CapeChange -= ChangeCape;
        EventManager.LeftHandChange -= ChangeLeftHand;
        EventManager.RightHandChange -= ChangeRightHand;
        EventManager.FocusBodyPartChange -= changeFocus;
    }

    public void ChangeHat(GameManager.Colours C)
    {
        HatColour = C;
        switch (C)
        {
            case GameManager.Colours.Blue:
                WizardObject.GetComponent<SkinnedMeshRenderer>().materials[3] = BlueBodyMat;
                break;
            case GameManager.Colours.Red:
                WizardObject.GetComponent<SkinnedMeshRenderer>().materials[3] = RedBodyMat;
                break;
            case GameManager.Colours.Green:
                WizardObject.GetComponent<SkinnedMeshRenderer>().materials[3] = GreenBodyMat;
                break;
            case GameManager.Colours.Yellow:
                WizardObject.GetComponent<SkinnedMeshRenderer>().materials[3] = YellowBodyMat;
                break;
        }
    }
    public void ChangeCape(GameManager.Colours C)
    {
        CapeColour = C;
        switch (C)
        {
            case GameManager.Colours.Blue:
                 WizardObject.GetComponent<SkinnedMeshRenderer>().materials[0] = BlueBodyMat;
                break;
            case GameManager.Colours.Red:
                WizardObject.GetComponent<SkinnedMeshRenderer>().materials[0] = RedBodyMat;
                break;
            case GameManager.Colours.Green:
                WizardObject.GetComponent<SkinnedMeshRenderer>().materials[0] = GreenBodyMat;
                break;
            case GameManager.Colours.Yellow:
                WizardObject.GetComponent<SkinnedMeshRenderer>().materials[0] = YellowBodyMat;
                break;
        }
    }
    public void ChangeLeftHand(GameManager.Colours C)
    {
        LeftHandColour = C;
    }
    public void ChangeRightHand(GameManager.Colours C)
    {
        RightHandColour = C;
    }

    public void changeFocus(GameManager.BodyParts newFocus)
    {
        FocusedBodyPart = newFocus;
    }
}

I have an EventManager that works and tells this when a change is made and what colour to change to.
The GameManager defines an enum for Colours, I know the areas are being called as the variable in the inspector (for the enum) changes to match.

When I removed the “s” from materials that can change the first entry though I need to change the others as well.

var materialsArray = GetComponent<SkinnedMeshRenderer>().materials;
materials[0] = myMaterial;
GetComponent<SkinnedMeshRenderer>().materials = materialsArray;

Thank you for that though I seem to be getting some other issue. In the inspector the skinned mesh shows 4 materials but the array only gets 3.
