UE5的RumtimeFBXImport插件其实只能加载本机的fbx文件，要加载服务器上的fbx文件的话，需要先将该fbx文件下载到本地，然后再使用RumtimeFBXImport插件加载。
示例文件如下：
#include "Loader/WebLoader.h"
#include "Misc/FileHelper.h"
#include "Misc/Paths.h"
#include "HttpModule.h"
#include "Http.h"
#include "FBXImportManager.h"AWebLoader::AWebLoader(){}void AWebLoader::BeginPlay()
{Super::BeginPlay();if (WebFbxPath.Len() > 0){LoadFileFromServer(WebFbxPath);}
}void AWebLoader::LoadFileFromServer(const FString& URL)
{TSharedRef<IHttpRequest, ESPMode::ThreadSafe> HttpRequest = FHttpModule::Get().CreateRequest();HttpRequest->SetURL(URL);HttpRequest->SetVerb("GET");HttpRequest->OnProcessRequestComplete().BindUObject(this, &AWebLoader::OnFileDownloadComplete);HttpRequest->ProcessRequest();
}void AWebLoader::OnFileDownloadComplete(FHttpRequestPtr Request, FHttpResponsePtr Response, bool bWasSuccessful)
{if (bWasSuccessful && Response.IsValid() && Response->GetResponseCode() == EHttpResponseCodes::Ok){FString ProjectRoot = FPaths::Combine(FPaths::ProjectDir(), LocalRelatedPath);FString FileName = FPaths::GetCleanFilename(WebFbxPath);FString LocalFullPath = FPaths::Combine(ProjectRoot, FileName);if (!FFileHelper::SaveArrayToFile(Response->GetContent(), *LocalFullPath)){UE_LOG(LogTemp, Error, TEXT("File downloaded failed!"));return;}//LoadLocalFBX(LocalFullPath);}else{UE_LOG(LogTemp, Error, TEXT("File download failed."));}
}void AWebLoader::LoadLocalFBX(FString LocalFullPath)
{if (!FBXImportManager){FBXImportManager = GetWorld()->SpawnActor<AFBXImportManager>();}FBXImportManager->InitializeFBXLoad();FBXImportManager->ImportFBXFile(LocalFullPath, FVector::UpVector, BaseMaterial, EFBXCollisionType::MeshCollision);
}
)
