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：
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。
