首先需要在**本项目**中cook内容，内容放在content文件夹下，cooked文件在[ProjectName]\Saved\Cooked\WindowsNoEditor\[ProjectName]\Content\[CookedFolder]

然后用引擎自带的unrealpak打包成一个pak文件 unrealpak D:\MyDesktop\Apple.pak -create=[ProjectName]\Saved\Cooked\WindowsNoEditor\[ProjectName]\Content\[CookedFolder] -compressed

最后在运行时加载：

void AMyActor::BeginPlay()
{
    Super::BeginPlay();

    OldPlatform = MakeShareable(&FPlatformFileManager::Get().GetPlatformFile());
    PakPlatformFile = MakeShareable(new FPakPlatformFile());
    PakPlatformFile->Initialize(OldPlatform.Get(), TEXT(""));

    TestLoadPak(TEXT("D:\\MyDesktop\\Apple.pak"));
}

void AMyActor::TestLoadPak(FString InFullPath)
{
    FPlatformFileManager::Get().SetPlatformFile(*PakPlatformFile);

    FString PakFileFullPath = InFullPath;

    FPakFile* TmpPak = new FPakFile(PakPlatform
