Unity材质球自动遍历所需贴图

Unity材质球自动遍历所需贴图

文章目录

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：

usingUnityEngine;usingSystem.Collections.Generic;usingSystem.IO;usingUnityEditor;publicclassAutoAssignTextureMaps:MonoBehaviour{publicList<Material> targetMaterials;// 在Inspector中指定目标材质列表privateDictionary<string,string> textureMapNames =newDictionary<string,string>{{"Albedo","_BaseMap"},// Base Color{"MAODS","_MetallicGlossMap"},// Metallic and Smoothness{"Normal","_BumpMap"}// Normal Map};[ContextMenu("_AlphaMat后缀自动补全")]voidAssignTextures1(){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")]voidAssignTextures2(){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}");}}}}Texture2DFindTexture(string textureName){string[] guids = AssetDatabase.FindAssets(textureName);if(guids.Length >0){string assetPath = AssetDatabase.GUIDToAssetPath(guids[0]);return AssetDatabase.LoadAssetAtPath<Texture2D>(assetPath);}returnnull;}}

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。
