Unity (role view) RTT renders the model onto the UI

Recently, I was thinking about whether the character selection interface uses a model to be placed directly or a texture. Then I thought of using the texture rendered by the camera to attach it to Kangkang. I couldn’t think of another way like this: Specific steps: Take a RenderTexture
. Just assign it to the camera-rendering dedicated for model rendering, and then assign it to the rawImage of ui:
the code is quite simple:

	public Camera camera;
    public RawImage rwimg;
    public GameObject player;

    RenderTexture rentex;
    // Start is called before the first frame update
    void Start()
    {
        //创建一张纹理
        rentex = new RenderTexture(Screen.width, Screen.height, 0);
        //清除背景颜色
        camera.clearFlags = CameraClearFlags.SolidColor;
        //将临时纹理赋给渲染模型的摄像机
        camera.targetTexture = rentex;
        //渲染纹理
        camera.Render();
        //将纹理赋值给rawimage，(ui)
        rwimg.texture = rentex;

    }
    private float mox;
    private void Update()
    {
        if (Input.GetMouseButton(0))
        {
            mox -= Input.GetAxis("Mouse X");
            player.transform.rotation = Quaternion.AngleAxis(mox * 10, player.transform.up);
        }
    }

UI related:
I took an image for backgrounding, and the above one is Rawmage:

The effect obtained:

Finally, if you can, please like it (every time I see someone like it, I feel physically and mentally happy + a sense of accomplishment)
ps: Add an appearance Problem:
There will be a problem with the model rendering depth on the mobile phone: resulting in:

the RenderTexture depth needs to be modified: (Thanks to the boss for clarifying the confusion)

 rentex.depth = 16;//或者24
