前言

Mesh Renderer和Skinned Mesh Renderer组件默认不显示Order，找了个工具显示一下。

源码

下面两个代码放入Editor文件夹中

MeshRendererInspector

MeshRendererInspector.cs

SkinnedMeshRendererInspector

SkinnedMeshRendererInspector.cs

using UnityEngine;

using UnityEditorInternal;[CustomEditor(typeof(SkinnedMeshRenderer)), CanEditMultipleObjects]
public class SkinnedMeshRendererInspector : Editor

}
