Untiy动态批量替换材质的Shader

有时我们需要批量替换材质球的Shader, 下面我写了个工具

using UnityEditor;
using UnityEngine;

public class MaterialShaderModifier : EditorWindow
{
    
    
    private string folderPath = "Assets";
    private string ShaderName = "";
    private Shader newShader;

    [MenuItem("Tools/Material Shader Modifier")]
    private static void ShowWindow()
    {
    
    
        GetWindow<MaterialShaderModifier>("Material Shader Modifier");
    }

    private void OnGUI()
    {
    
    
        GUILayout.Label("Folder Path", EditorStyles.boldLabel);
        folderPath = EditorGUILayout.TextField(folderPath);

        GUILayout.Space(10);

        GUILayout.Label("Property Name", EditorStyles.boldLabel);
        ShaderName = EditorGUILayout.TextField(ShaderName);

        GUILayout.Space(10);

        GUILayout.Label("New Shader", EditorStyles.boldLabel);
        newShader = EditorGUILayout.ObjectField(newShader, typeof(Shader), true) as Shader;

        GUILayout.Space(10);

        if (GUILayout.Button("Modify Shaders"))
        {
    
    
            ModifyShaders();
        }
    }

    private void ModifyShaders()
    {
    
    
        string[] materialPaths = AssetDatabase.FindAssets("t:Material", new[] {
    
     folderPath });

        foreach (string materialPath in materialPaths)
        {
    
    
            Material material = AssetDatabase.LoadAssetAtPath<Material>(AssetDatabase.GUIDToAssetPath(materialPath));
            Undo.RecordObject(material, "Modified Shader");

            if(material.shader.name== ShaderName)
            {
    
    
                material.shader = newShader;

            }
            
        }

        AssetDatabase.SaveAssets();
        AssetDatabase.Refresh();
    }
}

菜单栏–Tools–MaterialShaderModifier 打开工具面板

FolderPath:文件夹路径，
PropertyName:当前材质球的shader名字
NewShader；要替换的shader
ModifyShaders；确认替换按钮
