如何销毁游戏对象的材质并使用编辑器脚本向其中添加新材质？

Question

var newmat = AssetDatabase.LoadAssetAtPath("Assets/Materials/Univeral Render Pipeline Lit.mat", typeof(Material));

        var allgameobjects = FindObjectsOfType<GameObject>();

        foreach(GameObject go in allgameobjects)
        {
            if (go.GetComponent<Renderer>() != null)
            {
                if (go.GetComponent<Renderer>().sharedMaterial.name.StartsWith("Default"))
                {
                    DestroyImmediate(go.GetComponent<Renderer>().sharedMaterial);

                    // Add here the newmat material to the gameobject
                }
            }
        }

这将破坏从游戏对象中删除当前材质我如何向其中添加新材质？我想给它添加新垫子。

也许换材料就不用销毁了？

var newmat = AssetDatabase.LoadAssetAtPath("Assets/Materials/Univeral Render Pipeline Lit.mat", typeof(Material));

        var allgameobjects = FindObjectsOfType<GameObject>();

        foreach(GameObject go in allgameobjects)
        {
            if (go.GetComponent<Renderer>() != null)
            {
                if (go.GetComponent<Renderer>().sharedMaterial.name.StartsWith("Default"))
                {
                    DestroyImmediate(go.GetComponent<Renderer>().sharedMaterial);

                    //Add material
                    go.GetComponent<Renderer>().sharedMaterial = newmat;
                }
            }
        }

但我认为你也可以改变材料

var newmat = AssetDatabase.LoadAssetAtPath("Assets/Materials/Univeral Render Pipeline Lit.mat", typeof(Material));

        var allgameobjects = FindObjectsOfType<GameObject>();

        foreach(GameObject go in allgameobjects)
        {
            if (go.GetComponent<Renderer>() != null)
            {
                if (go.GetComponent<Renderer>().sharedMaterial.name.StartsWith("Default"))
                {
                    go.GetComponent<Renderer>().sharedMaterial = newmat;
                }
            }
        }

地形为terrain.materialTemplate
