当我更改 material 时，Unity 发射没有更新

Question

到目前为止，发射在我的游戏中有效 (see here)。我试图让我的车每 1-5 秒闪烁一种颜色，出于某种原因，当我将我的 material 更改为发射 material 时，发射不起作用。

Glow material

Normal material

这是我的代码，

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

public class Menu : MonoBehaviour {

    public Material glow_mat;
    public Material normal_mat;
    public float spin_speed;
    public SkinnedMeshRenderer renderer;
    public bool changing;
    public bool glow_change;
    public float change_amount;

    // Start is called before the first frame update
    void OnEnable() {
        StartCoroutine(changeColorStart());
    }

    IEnumerator changeColorStart() {
        yield return new WaitForSeconds(Random.Range(1, 5));
        glow_change = true;
        changing = true;
    }

    // Update is called once per frame
    void Update() {
        transform.Rotate(0, spin_speed * Time.deltaTime, 0);
        if (changing) {
            change_amount += Time.deltaTime * 2;//0.2s per 1
            if (change_amount > 1) {
                change_amount = 1;
            }
            renderer.materials[0].Lerp(glow_change ? normal_mat : glow_mat, glow_change ?  glow_mat : normal_mat, change_amount);
            if (change_amount == 1) {
                change_amount = 0;
                if (glow_change) {
                    glow_change = false;
                } else {
                    changing = false;
                    StartCoroutine(changeColorStart());
                }
            }
        }
    }
}

我已经开始工作了，如果您想知道需要在 material 更改后放置此代码，

mat.SetColor("_EmissionColor", targetColor);//Or whatever material change you have.
mat.EnableKeyword("_EMISSION");//This is a bug in unity

我在统一文档中找到了答案，here。
