UnityEngine.PostProcessing.MinAttribute引用错误

报错提示：

修改方法：

找到MinDrawer.cs，修改如下三处代码（红色字体）：

namespace UnityEditor.PostProcessing
{
    [CustomPropertyDrawer(typeof(UnityEngine.PostProcessing.MinAttribute))]
    sealed class MinDrawer : PropertyDrawer
    {
        public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
        {
            UnityEngine.PostProcessing.MinAttribute attribute = (UnityEngine.PostProcessing.MinAttribute)base.attribute;

完整代码如下：

using UnityEngine;
using UnityEngine.PostProcessing;

namespace UnityEditor.PostProcessing
{
    [CustomPropertyD
