如何停止将摄像头渲染到RenderTexture？

using UnityEngine;

public class CameraRenderTextureExample : MonoBehaviour
{
    public Camera camera;
    public RenderTexture renderTexture;

    private void Start()
    {
        // 开始将摄像头渲染到RenderTexture
        camera.targetTexture = renderTexture;
        camera.enabled = true;
    }

    private void StopRenderingToRenderTexture()
    {
        // 停止将摄像头渲染到RenderTexture
        camera.enabled = false;
        camera.targetTexture = null;
    }
}
