不可能的工作：在FBX模型導入腳本中生成模型的預置體

#if UNITY_EDITOR using System.Collections; using System.Collections.Generic; using System.IO; using System.Text; using UnityEditor; using UnityEngine;public class AnimImport : AssetPostprocessor {StringBuilder sb = new StringBuilder();//fbx動畫導入前的處理，對動畫集進行分段設置，劃分為各個子集void OnPreprocessAnimation(){var fpath = Path.GetDirectoryName(assetImporter.assetPath) + "/times.txt";if (!File.Exists(fpath)){//EditorUtility.DisplayDialog("缺少時間配置文件", assetImporter.assetPath + "的動畫分段文件time.txt不存在，動畫子集無法劃分", "ok");return;}var sr = new StreamReader(File.OpenRead(fpath), Encoding.ASCII);var longStr = sr.ReadToEnd();var dats = longStr.Split('\"');var anims = new List<ModelImporterClipAnimation>();for (var i = 0; i < dats.Length; ++i){if (dats[i] == "" || dats[i] == "\r\n")continue;var anim = new ModelImporterClipAnimation();var subdat = dats[i].Split(' ');anim.name = subdat[0];anim.firstFrame = float.Parse(subdat[1].TrimEnd('f'));anim.lastFrame = float.Parse(subdat[2].TrimEnd('f'));anims.Add(anim);}var modelImporter = assetImporter as ModelImporter;modelImporter.clipAnimations = anims.ToArray();}void OnPreprocessModel(){var modelImporter = assetImporter as ModelImporter;modelImporter.globalScale = 0.6f;modelImporter.importMaterials = true;modelImporter.materialName = ModelImporterMaterialName.BasedOnTextureName;}void OnPostprocessModel(GameObject go){var modelImporter = assetImporter as ModelImporter;//1，找到Materials文件夾下所有的材質文件，替換它的shadervar dir = Path.GetDirectoryName(modelImporter.assetPath) + "/Materials";var files = Directory.GetFiles(dir, "*.mat");foreach (var fs in files){var mat = AssetDatabase.LoadAssetAtPath(fs.Replace('\\', '/'), typeof(Material)) as Material;mat.shader = Shader.Find("Qx/Unity/Mobile/Mobile-Diffuse");}AssetDatabase.SaveAssets();//2，創建prefab到assets/res/prefabs/char/下//經試驗，查找文檔，發現在此方法（OnPostprocessModel）中創建prefab是不可能的，其它方法更不可能//方式一，這種方式加載出來的fbx是空的//var fbx = AssetDatabase.LoadAssetAtPath(assetImporter.assetPath, typeof(GameObject)) as GameObject;//方式二，這種方式雖然能成功創建預置體，但創建出的預置體上mesh引用為空（原因見U3D文檔）//var fbx = go;//PrefabUtility.CreatePrefab(Path.GetDirectoryName(modelImporter.assetPath) + "/testfbx.prefab", go); }} #endif
