Unity材质球自动遍历所需贴图

Unity材质球自动遍历所需贴图

---

---

一、原理

例如一个材质球名为：Decal_Text_Cranes_01_Mat ，
然后从全局遍历出：Decal_Text_Cranes_01_Albedo赋值给材质球的BaseMap,
全局遍历出Decal_Text_Cranes_01_MAODS 赋值给材质球MetallicMap通道，
全局遍历出Decal_Text_Cranes_01_Normal 给材质球NormalMap通道，
**规律：**材质球名字：Decal_Text_Cranes_01_Mat 把后面Mat换成通道名称，就是该材质球的通道贴图

二、用法

1.代码：

using UnityEngine;
using System.Collections.Generic;
using System.IO;
using UnityEditor;public class AutoAssignTextureMaps : MonoBehaviour
{public List<Material> targetMaterials; // 在Inspector中指定目标材质列表private Dictionary<string, string> textureMapNames = new Dictionary<string, string>{{ "Albedo", "_BaseMap" },   // Base Color{ "MAODS", "_MetallicGlossMap" }, // Metallic and Smoothness{ "Normal", "_BumpMap" }     // Normal Map};[ContextMenu("_AlphaMat后缀自动补全")]void AssignTextures1( ){foreach (Material material in targetMaterials){string baseName = material.name.Replace("_AlphaMat", "");foreach (var pair in textureMapNames){string textureName = baseName + "_" + pair.Key;Texture2D texture = FindTexture(textureName);if (texture != null){material.SetTexture(pair.Value, texture);Debug.Log($"Assigned {textureName} to {pair.Value} for material {material.name}");}else{Debug.LogError($"Could not find texture {textureName} for material {material.name}");}}}}[ContextMenu("_Mat后缀自动补全")]void AssignTextures2( ){foreach (Material material in targetMaterials){string baseName = material.name.Replace("_Mat", "");foreach (var pair in textureMapNames){string textureName = baseName + "_" + pair.Key;Texture2D texture = FindTexture(textureName);if (texture != null){material.SetTexture(pair.Value, texture);Debug.Log($"Assigned {textureName} to {pair.Value} for material {material.name}");}else{Debug.LogError($"Could not find texture {textureName} for material {material.name}");}}}}Texture2D FindTexture(string textureName){string[] guids = AssetDatabase.FindAssets(textureName);if (guids.Length > 0){string assetPath = AssetDatabase.GUIDToAssetPath(guids[0]);return AssetDatabase.LoadAssetAtPath<Texture2D>(assetPath);}return null;}
}

2.使用方法

1.将脚本挂载到一个空物体：
2.把所需的材质球添加到集合列表中。
3.点右上角三个点，进行调用脚本中的方法。
