Unity 编辑器开发实战【Model Importer】- 如何多选设置模型导入设置中的Material Location

模型的Import Settings中Materials部分是不支持多选进行编辑的，如图所示，如果我们选中多个模型，编辑器中会提示Material Editing is not supported on multiple selection.

假如我们往工程中导入了大量模型，其默认的Location设置为Use Embedded Materials，而我们想要将其设为Use External Materials(Legacy)，就需要依次选中模型、设置Location，比较耗时耗力。

本文实现的工具可以支持多选模型进行Material Location设置，如图所示：

代码如下：

  

   

    

     

    
    

     

      using UnityEngine;
     
    
   

    

     

    
    

     

      using UnityEditor;
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      namespace SK.Framework
     
    
   

    

     

    
    

     

      {
     
    
   

    

     

    
    

     
    public class ModelImportSettings : EditorWindow
     
    
   

    

     

    
    

     

          {
     
    
   

    

     

    
    

     
        private ModelImporterMaterialLocation location;
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

              [MenuItem("SKFramework/Tools/Model Import Settings")]
     
    
   

    

     

    
    

     
        private static void Open()
     
    
   

    

     

    
    

     

              {
     
    
   

    

     

    
    

     

                  GetWindow<ModelImportSettings>("Model Import Settings").Show();
     
    
   

    

     

    
    

     

              }
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     
        private void OnGUI()
     
    
   

    

     

    
    

     

              {
     
    
   

    

     

    
    

     

                  GUILayout.BeginHorizontal();
     
    
   

    

     

    
    

     

                  {

                      location = (ModelImporterMaterialLocation)EditorGUILayout.EnumPopup(location);
     
    
   

    

     

    
    

     

                  }
     
    
   

    

     

    
    

     

                  GUILayout.EndHorizontal();
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     
            if (Selection.gameObjects.Length == 0) return;
