C++ 在虚幻中创建地形时，使用ALandscape:：Improt API导入，图层信息设置失败

当使用ALandscape:：Improt API时，我想将层信息设置为之前保存的层，但设置失败，下面是我的代码

void FImpotLandModule::CreatLandScape(FString heightMapPath)
{

    UWorld* world = GEditor->GetEditorWorldContext().World();
    FVector location(0.0f, 0.0f, 0.0f);
    FRotator rotator(0.0f, 0.0f, 0.0f);
    FActorSpawnParameters SpawnInfo;
    ALandscape* landscape = world->SpawnActor<ALandscape>(location, rotator);
    ALandscapeProxy* proxy = Cast<ALandscapeProxy>(landscape);
    int section_size = 63;
    int section_per_component = 2;
    int component_x = 4;
    int component_y = 4;
    int quads_per_component = section_per_component * section_size;
    int size_x = component_x * quads_per_component + 1;
    int size_y = component_y * quads_per_component + 1;
    TArray<uint16> ImportLandscape_Data;
    ILandscapeEditorModule& editorModule = FModuleManager::GetModuleChecked<ILandscapeEditorModule>("LandscapeEditor");
    const ILandscapeHeightmapFileFormat* heightmapFormat = editorModule.GetHeightmapFormatByExtension(*FPaths::GetExtension(heightMapPath,true));
    if (heightmapFormat)
    {
        FLandscapeHeightmapImportData HeightmapImportData = heightmapFormat->Import(*heightMapPath, { 505,505 });
        ImportLandscape_Data = MoveTemp(HeightmapImportData.Data);
    }
    
    TMap<FGuid,TArray<uint16>> heightmapDataPerLayers;
    heightmapDataPerLayers.Add(FGuid(), ImportLandscape_Data);
    TMap<FGuid,TArray<FLandscapeImportLayerInfo>> landscapeLayersInfo;
    TArray<FLandscapeImportLayerInfo> importLandInfo;
    UMaterialInterface* landscapeMaterial = LoadObject<UMaterialInterface>(nullptr,TEXT("/Game/mapmaterial"));
    proxy->LandscapeMaterial = landscapeMaterial;

    if (landscapeMaterial != nullptr)
    {
        TArray<FName> layerNames = ALandscapeProxy::GetLayersFromMaterial(landscapeMaterial);
        importLandInfo.Reserve(layerNames.Num());
        for (int32 i = 0; i < layerNames.Num() - 1; ++i)
        {
            FLandscapeImportLayerInfo ILayerInfo = FLandscapeImportLayerInfo(layerNames[i]);
            ULandscapeLayerInfoObject* newLayerInfo = NewObject<ULandscapeLayerInfoObject>(proxy);
            FString layerInfoPath = "/Game/0" + FString::FromInt(i + 1) + "_LayerInfo";
            newLayerInfo = LoadObject<ULandscapeLayerInfoObject>(NULL, *layerInfoPath);
            ILayerInfo.LayerInfo = newLayerInfo;
            ILayerInfo.SourceFilePath = "d:/0" + FString::FromInt(i + 1) + ".png";
            importLandInfo.Add(MoveTemp(ILayerInfo));
        }
    }
    landscapeLayersInfo.Add(FGuid(), importLandInfo);
    proxy->Import(FGuid::NewGuid(),0,0,size_x - 1,size_y - 1,section_per_component,section_size,heightmapDataPerLayers,TEXT("MapHeightMap"),landscapeLayersInfo,ELandscapeImportAlphamapType::Additive);
}
