unity editor 读取FBX下的animtion clip文件

使用ModelImporter可以读取FBX下数据:

   ModelImporter modelImporter = (ModelImporter)AssetImporter.GetAtPath(modelAssetPath);
                                if (modelImporter && modelImporter.clipAnimations.Length > 0)
                                {
                                    //可能有animClip在fbx文件下面,表明是anim的规则判断
                                    regexString = string.Format(ctrInfo.animation_regex, assetFullNameRegex);
                                    fileType = "anim";
                                }
                                else
                                {
                                    regexString = string.Format(ctrInfo.model_regex, assetFullNameRegex);
                                    fileType = "model";
                                }
