## AnimSequence生成逻辑
```c++
//创建UAnimSequence
FString ParentPath = FString::Printf(TEXT("%s/%s"), *FPackageName::GetLongPackagePath(*Outer->GetName()), *SequenceName);
UObject* ParentPackage = CreatePackage( *ParentPath);
UObject* Object = LoadObject<UObject>(ParentPackage, *SequenceName, NULL, (LOAD_Quiet | LOAD_NoWarn), NULL);
UAnimSequence * DestSeq = Cast<UAnimSequence>(Object);
//设置骨骼
DestSeq->SetSkeleton(Skeleton);
//设置文件帧率率与重采样率
DestSeq->ImportFileFramerate = GetOriginalFbxFramerate();
DestSeq->ImportResampleFramerate = ResampleRate;
```
