Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Map from pak file missing materials and meshes

Hi everyone!

I've been working on this for a few days and I finally have it to a place where I think I'm close to it working. I'm trying to build a system which allows a user to download a .pak file from a server (this part is working) and launch a level from it in the game. Each .pak file is essentially a packaged level. Everything is working and I finally made it so that i can open console and type open minimal_default and it will load the level. (I have created a pak file from a blank project with starter content following these instructions)

The level loads, but none of the meshes or materials load, it's just an empty map. When I check the logs, I get this message repeated for each asset.

 LogStreaming: Error: Couldn't find file for package /Game/StarterContent/Props/SM_TableRound requested by async loading code. NameToLoad: /Game/StarterContent/Props/SM_TableRound
 LogStreaming: Error: Found 1 dependent packages...
 LogStreaming: Error:   /Engine/LevelTest/Content/StarterContent/Maps/Minimal_Default

My Code: This is the code I'm using the mount the pak file.

 UE_LOG(LogTemp, Log, TEXT("MountPak(%s)"), *FullFilePath);

 // get mod UID
 FString PathPart, FilePart, ExtPart;
 FPaths::Split(FullFilePath, PathPart, FilePart, ExtPart);
 FString PathPart2, ModUID, ExtPart2;
 FPaths::Split(PathPart, PathPart2, ModUID, ExtPart2);
 UE_LOG(LogTemp, Log, TEXT("ModUID=%s"), *ModUID);

 IPlatformFile& PlatformFile = FPlatformFileManager::Get().GetPlatformFile();
 FPakPlatformFile* PakPlatform = new FPakPlatformFile();
 PakPlatform->Initialize(&PlatformFile, TEXT(""));

 if (PakPlatform->Mount(*FullFilePath, 0, *(FPaths::EngineContentDir()))) {
     UE_LOG(LogTemp, Log, TEXT("Successfully mounted %s at %s"), *FullFilePath, *FPaths::EngineContentDir());
     UE_LOG(LogTemp, Warning, TEXT("Failed to mount %s"), *FullFilePath);

Product Version: UE 4.17
