Changing material on SkinnedMeshRenderer changes on other objects too

I have written a script that you can attach to a GameObject and it will allow you to hover over it and change the material to one with a different shader.

Here it is:

    public Material normal;
    public Material highLight;

    private new SkinnedMeshRenderer renderer;

    private void Start() {
        renderer = transform.GetComponentInChildren<SkinnedMeshRenderer>();
    }

    private void Update() {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;

        if (Physics.Raycast(ray, out hit, 100)) {
            if (hit.transform.gameObject.tag == transform.gameObject.tag) {
                renderer.material = normal;
            }

            if (hit.transform.gameObject.tag != transform.gameObject.tag) {
                renderer.material = highLight;
            }
        }
    }

I’m using this to highlight when a player hover over an enemy and these two enemies share a similar mesh. So, when I hover over one the other enemy is also highlighted.

How do Is stop this from happening?

Hover over… If by saying this you mean the mouse, then it’s simple: use OnMouseEnter() and OnMouseExit().

 void Start ()
 {
      GetComponent<Renderer>().material = normal;
 }

 void OnMouseEnter ()
 {
      GetComponent<Renderer>().material = highLight;
 }

 void OnMouseExit ()
 {
      GetComponent<Renderer>().material = normal;
 }
