packaging

[winged moss]

the bootstrap launcher just checks dependencies are installed and then runs the real exe in Binaries/Win64

[torpid hull]

so in my case I'm wondering if I can have both test and development in the same folder - so I have UE4Client.exe and UE4Client-Win64-Test.exe down in the Binaries/Win64

[winged moss]

uh so this is a BP only project?

[torpid hull]

so then I wonder how this bootstrap can even know which one to launch - since I only have one bootstrap launcher (ElementalDemo.exe) up higher

It's elemental, so yes

(I think so)(

[winged moss]

the exe name is a bit of a giveaway, with a code project you can just compile the test/dev exes and use it against the same cooked content if you wish (if you're using the "test" config for the paks you might miss some content). with a BP project, I think you have to specify the uproject path as an argument with those exes

[torpid hull]

ok thanks - good to know that could work - I'll give it a try - thanks again

Hey everyone,

Is there new packaging settings in 5.2? I tested my project with both preview 1 and 2, and my package size increased from 3.0 GB to 7.33 GB!

[alpine plank]

The problem has been resolved on my packaging. It turns out that 8.0 GB of RAM was barely enough for UE 5.1.1 to package a whole project. But now, my laptop has four times the memory and it packages at a much faster speed.

[winged moss]

8GB is barely enough for development, let alone a CPU intensive job like packaging

[mystic atlas]

8GB is barely enough just to run windows comfortably.

[mortal ridge]

I swear I didn't change my packaging settings at all, but now every build I try to make is corrupted apparently?

ERROR: System.ComponentModel.Win32Exception (1392): An error occurred trying to start process 'C:\Users\[redacted]\Documents\Unreal Projects\Gravedigger\Saved\StagedBuilds\Windows\Gravedigger\Binaries\Win64\Gravedigger.exe' with working directory 'C:\Users\[redacted]\Documents\Unreal Projects\Gravedigger\Saved\StagedBuilds\Windows\Gravedigger\Binaries\Win64'. The file or directory is corrupted and unreadable.

I've deleted everything in that StagedBuilds folder and restarted my computer, but no dice

[mortal ridge]

Okay I tried packaging on another computer, which sucks because it's WAY slower, but it WORKED. So somehow the setup of unreal on my primary packaging machine is fucked

[winged moss]

did you try deleting Intermediate?

[lunar heron]

i repost this, cause trying to have an answer since month now.

Is there a way to have symbol with game packaged ? to catch error when the player crash.

[winged moss]

generally you should not distribute the PDBs to end-users, unless you want to open the floodgates to reverse engineering

[lunar heron]

yeah it's just for internal testing.

not external.

[winged moss]

okay then use the packaging setting for it and your PDBs should be alongside the game exe

(the one in Project/Binaries/Win64)

[lunar heron]

Hum... is there a setting for this ?

[winged moss]

but for actual production use, you should consider something like BugSplat or one of the many alternatives, or even roll your own if you have the resources

[lunar heron]

Sorry to re-ask, i'm maybe dumb, but do you have the name of the setting ? i can't found it.

[winged moss]

is it a lot to ask to type "symbols" into project settings?

actually it might be "include debug files"

[lunar heron]

this is presiely why i'm asking, cause

and include debug files in shipping builds does not bring PDB

i remember in UE4 this was a setting

but in UE5, i can't find it.

[winged moss]

and are you checking inside ProjectName/Binaries/Win64? The bootstrap exe won't have them

but whatever is building your game be a it a dev machine or build server, it should exist on the file system

[lunar heron]

There is the PDB in binary yup.

[mortal ridge]

Which folder specifically? This could definitely be the problem.

Hello everyone, when releasing an UE game through Steam, how do you handle the different .ini files throughout the life of the project? Let's say you update, how do you handle the new updates without overwriting an user settings?

I was considering not providing an .ini file with the Steam version and have the game build them on first start but I'm wondering if there's a canonical way to do it that might be different.

(I don't mean just UE default inis, I'm using some custom files)

[winged moss]

What? The inis from ProjectName/Config are coalesced and packaged with the game

And I don't know how "custom files" is relevant here when you just distribute the defaults and user settings get applied on top of the defaults

If you need to change major things with user configs then implement versioning

[velvet grotto]

if I distribute the default as part of the default package, whenever there's an update steam will overwrite the users' ini with the new defaults

[winged moss]

Distributing an update will distribute the updated defaults. It will not overwrite the user's configs

[velvet grotto]

The inis are not generated by UE, they are custom inis that I make myself. They ARE overwritten.

[winged moss]

Then why are you asking here if it's a completely custom implementation?

And I mentioned versioning. That's what I did before. When the version is incremented and the config has an old version, you can clear it or execute an upgrade path

[velvet grotto]

If you hate helping people you are not obligated to.

[winged moss]

Huh? I reiterated a solution I mentioned earlier

But yeah this is #packaging and this relates to a project specific config system

[velvet grotto]

I'm asking for a "best practice", it goes without saying that I'm not familiar with the best way to do things. Talking to me as if I'm dumb for asking advice when I'm not following the canonical way is not going to bring any help

Is there a better channel for this question?

[winged moss]

The general channels, #programmer-hangout maybe, since this is best practices. But having config versions is the easiest and most viable way to do it

#cpp if it's implementation details

[velvet grotto]

Thanks for taking the time.

Hi, does anyone know way of passing arguments to UAT from editor? I have game with 2 build targets and since moving to UE5 it complains about not specyfying 'Target' argument for UAT during build.

Anyone else have issues with the metahuman hair when trying to 'Cook Content' for Windows?

There are a lot of errors, but I assume that the root of the issue is that texture file.

When trying to edit the texture and save it, I get this error.

I'm not too sure how I would recreate this one file since Metahuman textures are imported by importing an entire metahuman. Do I need to delete the metahuman folder and reimport all of them?

[hardy hatch]

Hey there.
I have an Object following a Spline.
Setting it up it's just how you'd expect it to be. Playing in Editor, everything is fine. But once I build it, the Start Point of the Spline [in the packaged Project] gets moved to 0/0/0.
We suspect that it has something to do with World Partition since the Objects following the Spline are Instances and as such may struggle with World Partitioning.
Either way, is there some way to fix this?

this is where it used to start

btw it only happens to instanced objects specifically

[crude relic]

Hey y'all, I'm running into an issue after packaging my game, and I'm not quite sure what is going on (no errors).

This is for UE 5.1.

I have my build configuration set to shipping, I have each of my maps included in "List of maps to include in a packaged build".

When I package the game and try to test it, I can get from my main menu to my first level fine, but when I try to go from my first level to my second level, it sends me back to the main menu.

Everything works fine in the editor, I've checked several times that everything is spelled correctly for opening the next level.

This is using blueprints only (but doing this here since it seems to be a packaging issue as far as I can tell).

I'm not sure if there is another packaging option that I'm completely missing or if any of y'all have encountered this before and might know what is going on.

I've done a search through the unreal engine forums and didn't see a solution there, so figured I'd ask y'all in here.

Additionally, this is a game that I've made and that runs fine in UE4.27. I made a copy in 5.1 to update the game to 5.1 and cleaned up a lot of the back end, but none of the levels or menus were adjusted for this process.

So I know, functionally, the game can run, this just seems to be a weird quirk.

Since "List of maps to include in a packaged build" seems to be new (at the very least, I didn't need to specify them in ue4.27), I'm not sure if something else is affecting the packaging process.

[winged moss]

that feature is not new. I would suggest: seeing the log from the packaged game, checking the PAK files to see if the map ended up in the build, combing the packaging log for any references to the level and see if any warnings are emitted

how you're changing the level may also matter. there are specific nodes for map travel (in case you're running the "open" console command via BP)

[heavy fulcrum]

yes

;-;

[errant badger]

Any idea why this error is happening?

[naive ridge]

Usually it is some dependency modules in your project has not been added in the build list. Just check <projectname>.build.cs

[errant badger]

Well shouldn't that be an error at building then?

But it's a packaging error..

[naive ridge]

Is it a win64 pack or other platforms?

[errant badger]

win64

[naive ridge]

Checked online and are you sure any plugin using are right version for Unreal?

[errant badger]

they're all using 5.1

[errant badger]

and online didnt find anything particular regarding this

[naive ridge]

Do you have any precompiled plugin or are they compatible with 5.1?

[naive ridge]

OK, one suggestion is delete all binaries and intermediate folders and try a full rebuild.

Anyone knows what's up with that? I'm making windows Shipping build: UATHelper: Packaging (Windows): Missing precompiled manifest for 'MessageLog', 'C:\Program Files\Epic Games\UE_5.1\Engine\Intermediate\Build\Win64\UnrealGame\Shipping\MessageLog\MessageLog.precompiled'. This module was most likely not flagged for being included in a precompiled build - set 'PrecompileForTargets = PrecompileTargetsType.Any;' in MessageLog.build.cs to override. If part of a plugin, also check if its 'Type' is correct.

[winged moss]

And what is MessageLog? I don't see a Build.cs for that in vanilla UE

Is this a plugin acquired from a location other than marketplace and you installed it to the engine rather than the project?

[mystic atlas]

I have a build.cs for it right here in vanilla ue!

Though, it does this if (Target.bCompileAgainstEngine && Target.Configuration != UnrealTargetConfiguration.Shipping) { PrecompileForTargets = PrecompileTargetsType.Any; }

So it's not gonna be in the precompiled stuff for shipping builds.

[winged moss]

oh I don't know why it didn't show up, must've been a typo

when you see that error in the binary engine you might be SOL if it's an engine module

though since this module is logging related, and the binary engine forces you to disable logging for shipping builds, then you might want to remove this module from shipping builds

[unique merlin]

That's unfortunate indeed. Do you know how to remove it from shipping build?

[winged moss]

in Build.cs, you can make it condition on Target.Configuration != UnrealTargetConfiguration.Shipping

you will need a preprocessor define to gate any calls to the MessageLog module

[unique merlin]

that looks like pain in the ass, isn't a better solution? like editing .uproject? and turn it off completely

[winged moss]

when using the binary engine you don't really get the choice

unless it actually does something bad, I wouldn't really worry about it, ie. it's related to the actual error you saw earlier in the log

Fair enough, it's just that i couldn't find any information on it on the internet either, so its a big mystery to me what the error means. It could be a potential performance hit that i dont know about

well if you were worried about performance, then you'd package your game on the command line instead

I'm sorry that not really familiar with Android metadata, but you must get something from google like token, crypto key or something like store product ID then it goes to a metadata file generated from the store dev account (I guess).

For most console platforms, it is like that.

Hi all! After packaging a shipping version and uploaded it to the Epic Games Launcher, there's an issue when a user has downloaded the game. Install and download via launcher works fine, but when starting the game there's a dialog saying "Microsoft Visual c++ runtime" is needed to run this game. Not that strange really, but is there a way of including this in the build/install? Or will this always be something the user need to download separately?

There was a way 🙂 Including the installer as prerequisite with BuildPatchTool!

So I'm implementing Steamworks support following the method in the below video, and I was wondering if there's a way to get the steam_api64.dll file to automatically get copied into the resulting Binaries/Win64 folder as part of the packaging process?

Instead of excluding by default and adding map/asset folders individually, you can include all by default and exclude folders manually as necessary:

At last every video say that build not successful

Can you suggest me which i should follow

[random glen]

If the package is too big and you can't delete project files to make it smaller, you will have to upload to Steamworks via the SDK. Uploading through the SDK is the normal way of doing things anyway, and has a lot of features, so it is worth figuring out.

[gilded drift]

hey so im trying to package my game and i got this error almost instantly after starting to package
i can share my logs if necessary

[tiny birch]

Got a bit of an odd one, posting here just in case someone's come across it.

Using an EOS plugin which seems pretty stable, but I've been having issues with it in packaging for other platforms. Fresh cloned UE from source, set up platform SDK's and a new project and tried to package - ran into an issue where a header file is duplicated in my uhtmanifest.

Internal Compiler Error: System.ArgumentException - An item with the same key has already been added. Key: EOSSubsystem.h

As you can see in the image, PublicHeaders contains four of the same header file which I'm pretty sure is the cause of this error 😅

If anyone has pointers it would be massively appreciated

[tiny birch]

Is there a reason you need it to be 2GB? I'd suggest using SteamCMD, no limits on that AFAIK

[primal thorn]

hello i'm making a shipping linux dedicated server and it's creating a ProjectName-Linux-Shipping.debug file that takes a lot of space, how do i prevent it from being created since i don't want to debug it?

i have that disabled

[uneven drift]

Hey guys, I'm looking for some advice regarding disabling features for builds. Can you recommend any good practices, programming patterns, Unreal features or tools I can employ to make it easy to quickly disable (and re-enable afterwards) certain functionality (dev/debug tools but also features that should not go into the next build) before packaging?

[hearty niche]

Yes thank you - I didn’t realize there was another way so I’ll start looking into that.

[sweet quiver]

Hi there I bang my head against the packaging. I haven't done it in a while and last time I build my game to send it to some friends most sounds where missing, some are working and also niagara effects are missing. I have not really an idea what is happening. Does anyone have a hint for me where I could start investigating?

[twilit yacht]

Bit of a silly question perhaps - I'm wondering if anyone has resources for how to do dedicated server build/packaging using GitHub actions or some other CI/CD setup? As I understand it, the only way to build a Dedicated Server target is via a source build of UE4/5, which would mean my CI/CD build agent needs the same source build of the editor that was used to create my project? Has anyone run into this scenario?

[flat violet]

Hi, I created .pak files for updating the game at runtime and when I update the game and click play it gives me this error, after restarting the game everything works and the map has updates

[flat violet]

Hi, how did you fix this?

[zinc terrace]

How do I change the path for save files in the game? Because when they are saved to the game folder, when you update the game on Steam, they all get lost. In Unreal 4, this was not the case, a folder was created in Appdata. How can I fix this in unreal 5.1?

[random glen]

I don't believe this has changed. In UE5.1, FPaths::ProjectSavedDir() should result in a directory within %appdata% for Shipping packaged builds. Development packaged builds probably still point to within the game folder.

[zinc terrace]

I put up for shipping

[random glen]

Are you using FPaths::ProjectSavedDir() to get the directory? It's definitely working for me.

Anyway I gotta go, hope you can figure it out.

[zinc terrace]

bleuprints does not have a node with a path 🧕

[scenic marlin]

Hey. Anyone knows how to set some default command line arguments when packaging a game? I tried Project Launcher's "Additional Command Line Parameters", and the hint says exactly what I want to hear, but it does nothing. (Should've posted this here, not in General)

[worthy wigeon]

Is there any guide or tips that people can give for taking a build that typically packages in 3 hours to something more like 15-45 minutes. In my last studio our build system was screaming fast but I never looked into how they were achieving that. I don't think they just threw hardware at the problem, although that could be possible.

For packaging for steam we have a large engine compile that I feel like it should skip since it should have engine binaries that are up to date. Additionally when it goes to make UGS builds it also takes a while after the steam builds. It's almost like the two are fighting over a cache that gets wiped out on each build?

Perhaps there is a way to tell unreal that if the build configuration is different to then use a different cache? We use jenkins but if I just get the unreal details I am sure I can figure out a way to utilize them in jenkins.

[keen moss]

Hey folks. Any packaging error experts in here? I have no clue what I'm looking at here to be able to sort out why my build is failing:

[random glen]

If you are looking for a blueprint node, BlueprintPathsLibrary has the "ProjectSavedDir" function, which is exposed as a blueprint node. The contents just return FPaths::ProjectSavedDir() as a String. So I'm not sure how you're doing it currently, but if you use that node to get the save directory it should work in a Shipping packaged build.

[zinc terrace]

This node only shows, it cannot be changed.

[random glen]

It returns a path (as a string) you can use to specify where to save your game data. It should function correctly, solving your problem (as you explained it), so I don't know why you would need to change the node.

If you want to create a custom directory somewhere else for save data, you will probably have to implement your own solution.

[zinc terrace]

It returns a path. But this does not allow us to change it.

[random glen]

It returns a path as a String. This String is a text representation of the Saved directory path (which should direct to somewhere in the %appdata% folder in Shipping builds). You can modify Strings, or make your own as necessary. If you don't like the path the node gives you, you will need to make your own String representing the path you want, either through Blueprints, or in C++ code. I hope this helps.

If you need more help, this is the sort of question that ChatGPT can probably assist you with if you do some Q&A with it.

[zinc terrace]

Now it is clear where you get these incomprehensible answers. I also asked this question to ChatGPT and he turned out to be a complete clown, coming up with random answers with non-existent nodes and solutions. Thanks for the "help"

[grand shadow]

Greetings everyone 👋
I would like to preview 😊 a level on an Android tablet but keep running into shader compiling errors in the debug log.

For previewing on an Android device (before packaging), what are the ideal steps to take to neutralize the shader compilation errors? 🤔

All settings are set to build, display, and render on the lowest quality available.

Thank you for considering my inquiry 🙏

[light junco]

To be fair, the answers aren't incomprehensible. They simply assumed and asked if you are using that Node (which does exist), because it should still point to the appdata folder.

If you are using the SaveGame system of UE, for Blueprints for example, and you aren't actively specifying a path anywhere, then it would ultimately call this:

FString FIOSSaveGameSystem::GetSaveGamePath(const TCHAR* Name)
{
    return FString::Printf(TEXT("%s""SaveGames/%s.sav"), *FPaths::ProjectSavedDir(), Name);
}

Which means it falls back to the ProjectSavedDir:

const FString& FPaths::ProjectSavedDir()
{
    FStaticData& StaticData = TLazySingleton<FStaticData>::Get();
    if (!StaticData.bGameSavedDirInitialized)
    {
        StaticData.GameSavedDir = UE4Paths_Private::GameSavedDir();
        StaticData.bGameSavedDirInitialized = true;
    }
    return StaticData.GameSavedDir;
}

That UE4Paths_Private::GameSavedDir() should ultimately point to the appdata folder.

This does ultimately go down the rabbithole of calling return FPaths::Combine(FPlatformProcess::UserSettingsDir(), FApp::GetProjectName()) + TEXT("/");

Where FPlatformProcess::UserSettingsDir() should be, again the appdata folder

There are some ways to override this, but since you want it to just work the way it did in UE4, there shouldn't be anything for you to do.

Although it can totally be that if you upload Dev builds instead of Shipping, that you might run into saving into the projects folder instead of the appdata one.

This is where it controls if it should save to project or user settings:

if (ShouldSaveToUserDir())
    {
        // if defined, this will override both saveddirsuffix and enginesaveddirsuffix
#ifdef UE_SAVED_DIR_OVERRIDE
        return FPaths::Combine(FPlatformProcess::UserSettingsDir(), TEXT(PREPROCESSOR_TO_STRING(UE_SAVED_DIR_OVERRIDE))) + TEXT("/");
#else
        return FPaths::Combine(FPlatformProcess::UserSettingsDir(), FApp::GetProjectName()) + TEXT("/");
#endif
    }
    else
    {
        return FPaths::ProjectDir();
    }

bool FPaths::ShouldSaveToUserDir()
{
    static bool bShouldSaveToUserDir =
        FApp::IsInstalled()
        || FParse::Param(FCommandLine::Get(), TEXT("SaveToUserDir"))
        || FPlatformProcess::ShouldSaveToUserDir()
        || !CustomUserDirArgument().IsEmpty();
        
    return bShouldSaveToUserDir;
}

[zinc terrace]

I use only Blueprint, the Shipping version, and have tried other build types. It still saves to the game folder.

[light junco]

It should return true for FApp::IsInstalled though

So it should save to the correct folder

You could try passing SaveToUserDir as command line arg

And see if that forces it

#if UE_BUILD_SHIPPING && PLATFORM_DESKTOP && !UE_SERVER
        bool bIsInstalled = true;

Relatively sure this auto defaults to installed if you are using shipping on a PC

[zinc terrace]

I don't use C++, I don't know what to do with it.

I don't understand why they broke it in 5.1. I didn't do anything out of the ordinary, it was just like on 4.

And now, because of this, the saves in my game go to the grave every time it is updated on Steam.

[light junco]

I'm just posting you proof for how it's working

There is no need to use C++ for this. Again, if it isn't working try the command line argument when starting it

And see if that forces the correct saved file path

[zinc terrace]

What exactly should I write in the command line?

[light junco]

I assume -SaveToUserDir

[zinc terrace]

I entered it, but there is no such command in the lists.

[light junco]

Command line

That is part of you starting your .exe game

Not part of the Editor

[zinc terrace]

?

[light junco]

no

Again, command line arguments are specified as part of you starting your packaged .exe game

Not in the Editor

You either use cmd or whatever command line software of your chose to navigate to the file location and execute the .exe with -SaveToUserDir

Or you create a shortcut to your exe, open its properties and append the -SaveToUserDir to the path

This is mainly for debugging anyway. It shouldn't be needed, but worth testing

[zinc terrace]

I entered this into the launch options in Steam and it worked, wow!

Thank you!

[light junco]

No worries. You should still question why that is needed, because it might be something else that is actually wrong here.

--

Is it actually possible to make arbitrary Target files to simply create different packages for the same platforms?
Does that involve more than just creating the Target.cs file or are those limited to predefined words (similar to the Server one)?

The main idea here would be setting some different config variables for different builds.

[zinc terrace]

I entered this into the Steamworks arguments and it works, for my game, I don't need more than that.

[light junco]

You say that, but your game apparently thinks that it's not properly installed

That's something to keep in mind :P

[zinc terrace]

She doesn't think anything, she does what I tell her.

There is a high probability that this is a problem 5.1

As well as disconnecting cables, but these are just the ones I've encountered.

[shut remnant]

Hey, I have a slight problem in understanding how exactly does packaging work for my cpp/bp project. As I want to integrate automation into it I naturally started to search how to package the project from console. I Tried to follow this article https://github.com/botman99/ue4-unreal-automation-tool but found myself even more confused. Let's say i have latest changes from the repository and no binaries/intermediate files etc.

As I understand, after using this command

RunUAT.bat BuildCookRun -project="D:\Repos\AutomationTestProject\AutomationTestProject.uproject" -noP4 -platform=Win64 -configuration=Development -clean -build -cook -allmaps -stage

the UAT will build, cook and stage my whole project that can be launched and played without any additional steps required?

I also encountered BuildGame and BuildEditor commands. What are they for? Just for building? 🤔 Do they function the same as launching Engine\build\batchfiles\build.bat with appropriate args?

for example does calling

RunUAT.bat BuildEditor -project="D:\Repos\AutomationTestProject\AutomationTestProject.uproject" 
RunUAT.bat BuildCookRun -project="D:\Repos\AutomationTestProject\AutomationTestProject.uproject" -noP4 -platform=Win64 -configuration=Development -nocompileeditor -clean -build -cook -allmaps -stage

result in the same thing as above? If not, what's the difference? 🤔

[keen moss]

Is there a good method for narrowing down which errors in a log are causing a packaging/cook failure? I'm just not sure what the best practices are for reading logs and deciphering what's going on.

[winged moss]

there's FPaths::Combine

oh damn

Paying whoever can fix my problem with packaging a multiplayer session test game

when i package game i get this error
LogInit: Display: LogBlueprint: Error: [AssetLog] D:\Games\Igra\MenuSystem\Content\ThirdPerson\Blueprints\BP_ThirdPersonCharacter.uasset: [Compiler] Could not find a function named "CreateGameSession" in 'BP_ThirdPersonCharacter_C'.

Please refresh node or break links to remove pin. from Source: /Game/ThirdPerson/Blueprints/BP_ThirdPersonCharacter.BP_ThirdPersonCharacter

and when it packages it only shows that

If u have an idea dm me i will give u my c++ code

[winged moss]

weird place to handle sessions, but where does the CreateGameSession function originate from? is it a plugin

[sullen plank]

It is from steam online subsystem plugin

And in the course he made it in third person bp when u click 1 to call the method creategamesession

[winged moss]

I doubt it because the OSS has very little exposed to BP and I can't find it

[sullen plank]

I made a bpcallable void

In the header file

So its callable

[winged moss]

yeah that's a bad place for it, but bad tutorial aside, it's likely because your game module tries to load BP_ThirdPersonCharacter before the plugin module that adds that node is loaded

[sullen plank]

How can i fix that

[winged moss]

add the plugin that node was added to Build.cs is an easy-ish way

but you can't modify engine plugins without a source build, so are you sure?

[sullen plank]

Because i really need to figure this out

[winged moss]

yes, this is a terrible way of doing it. I'm not sure why you'd pay someone for following a bad tutorial, but here we are

BP_ThirdPersonCharacter should be a subclass of MenuSystemCharacter if it's not, and you'd want to make sure that the game module is properly referenced in Target.cs, and the uproject file

[sullen plank]

Yeah thanks, but i don't know how to do most of that

Actually I can't do none of the things u said

Im very new to this

[winged moss]

<GameName>.Target.cs should have a reference to the game module, the uproject file (which is just a JSON file) should list the game module and have the type as Runtime

[late jewel]

you ever find a fix ffor tthis?

[rapid flint]

How come when I package a game it runs so much worse than when it is in the editor

When I play the game in the editor it doesn't even use 20% of my GPU to run 4 instances, but once I package and run or click "Launch" it uses 90-100% of my GPU.

with ue4.27, we are looking to build lighting for multiple levels with sub levels via command line.

I tried adding a -LoadSubLevels flag to the resavepackages command but it didn't appear to do anything.

When we build lighting in editor, it only works if we load all the sub levels first. How can you get around this so you can build lighting via command line for levels that have multiple sub levels?

Did they change unrealpak.exe in 5.1? It packs all my files in the same directory, but running the same command with the 5.0 exe instead of 5.1 the directories show correctly with -list

[inner island]

Bro that was in August of last year - presumably I think I ended up remaking the data structure entirely. Sorry I have no idea unless you scroll down and see that I had answered it and figured out how

Come to think of it it probably was a blueprint nativeization error and I think I just turned that off

[late jewel]

Its all good no worries, I found it had to do with changing a plugins version number to be compatible and rebuilding the blueprint

Hello! I'm trying to build my game for Quest but it's failing. I've gone through the setup a few times already but can't find what I did wrong. I hope someone here has more experience with this

Help plz

[dreamy sequoia]

I've been asking chatGPT for help with packing stuff and honestly it's been amazing so far. I highly recommend it. It doesn't quite figure the exact issue out right away for me, but upon looking back after problem solving it certainly pointed me in the right direction.

[winged moss]

Yeah except when it gives something that sounds correct but isn't

[pine sequoia]

Anyone know if there is a way to package a project for either a web build or some way to allow for gameplay on the web from Unreal?

[runic stratus]

It won't package because it says I need to install Visual studio 2019 but I already have it installed

[wicked rampart]

If your game is built for web, then yes

[pine sequoia]

Do you know of any reference or guidance on how to do so? I’ve seen some advice on older versions of Unreal, but nothing for newer versions.

Doesn’t have to be web gl either. Could be something else, my experience with packaging is fairly limited so even having some search terms to get me started on the right path

[wicked rampart]

I believe the term should be Pixel Streaming

Hello again people, I'm having a problem where the supported agents nav meshes are not being exported, except one, when packaging the game, I've been looking around in project settings and in the nav mesh and there is nothing about packaging, this causes the different sized npcs I have in my project to not move, this works perfectly inside editor and only happens in packaged game, anybody knows how to fix this? Thanks in advance!

EDIT: It just fixed by itself, for now, until it breaks again, sometimes I love Unreal...

[wooden vector]

hello I encounter missing plugin script when building. how do I manually include plugins scripts?

I tried this method and it didn't work

[winged moss]

/Script/... is a virtual path for native classes and that is not part of the cooking process. But with overly censoring your screenshots it's kinda hard to tell what's going on.

Do you have a class that loads a Blueprint that references a native class from the plugin? If that's the case you can usually fix it by adding the plugin's module to your Build.cs

Since that'll guarantee the plugin module is loaded before the game module

[azure shell]

Hey, I'm attempting to build certain parts of my game using the build tools, and I seem to be running into loads of errors. I'm trying to sort them so I can determine better workflows to ensure we can build and package easily in the future.

These compile and work fine in editor, but the build process seems to hate a bunch of custom structs? Do I need to do something to manually add these into the build tools so they don't get flagged as unknown?

[azure shell]

For anyone searching later: You need to refresh all blueprint nodes in order to clear these errors.

[wooden vector]

I'll try that when I wake up. Thank you for replying. For more information, I have this plugin that is build for 5.1 but I upgraded my project to 5.2 preview. Now it's pain to reverse to previous version, uassets aren't backward compatible. So I kept making the game until I pack the project. I got these errors that plugin files are missing, but it seems fine when I use them in editor.

Also I am not sure about this. The method is to have plug-ins in project plugin folder and not to have them in Unreal engine marketplace folder

i have this "cook failure" error. i have:
added my maps to packaging,
deleted saves, intermediate, and derived data cache. pls help im doin a game jam ;-; ❤️ ty!

[winged moss]

Well show your Target.cs file then...

[winged moss]

Show the preceding lines, particularly the warning/error summary

[quiet comet]

so i realized it was a widget that had errors. I updated a header file in visual studio, but its not updating in the engine for some reason, is there an extra step for compiling/refreshing so the changes in the header appear in project?

[winged moss]

Show actual errors, not a loose description of errors

[tepid grail]

Sorry! I managed to fix it, it was because of - in the name which when it generates the cs uses the project name as the class name which can’t have -

I was posting on ue-general at the time, but thank you!

The codes all generated by UE so didn’t think much off it

[wooden vector]

does it have to be in the version to get plugins work?

not sure why is failing to find scripts

the worst case I have to fix this problem is rebuilt my whole game in UE5.1, Uassets aren't backwards compatible.

these plugins are fine in editor tho

[ionic mulch]

Bumping this question again, if anyone has faced a similar issue, please let me know 🙂

hi there any one has ever had a problem with mediaplate looping only when packaged ?

Hi, I've created a blank empty project with 5.2 to test, and I'm receiving the following error code when trying to package.

[amber lake]

Someone please help:

Packaged Win game size is over 40+ Gb

It includes the project file and the contents that’s why it’s this big, how can i remove/ prevent that?

[random glen]

There are a lot of things that can be done, but to start with:

• Ensure that compression is enabled in your packaging settings
• Find and delete assets that aren't in use and which are no longer necessary. I think there might be some free or marketplace plugins which can help with this. The editor also has a built-in size map so you can see what files are taking up the most space.
• Don't include test assets or other unnecessary/unused assets. You can set which folders to ignore in the packaging settings.
• Sometimes assets are way bigger than they need to be. Especially things like textures (and this can affect in-game performance too), or if you have meshes with billions of polygons. A lot of 4k textures can be changed to 2k or 1k with little visual difference, and you can get a big space and performance boost in many cases. Might need to export, modify, and reimport the texture for it to affect the package size (just changing the parameters probably won't do it)

[winged moss]

pak compression is sometimes a mixed bag. also unless you selected to cook everything, it shouldn't even cook unreferenced assets

disabling plugins that are unused can reduce the overall size

[winged moss]

though I don't know what "the project file and the contents" means in regards to the packaged project

[frail hornet]

So on ue4 if you cook for windows you get ubulk/uexp/uasset but when I do the same on ue5.1 I get a shader file, where is the ubulk/uexp/uasset or how do I get them on ue5.1 ? If anyone knows and replies please @me

[winged moss]

the "shader file" being?

[frail hornet]

ShaderAssetInfo and ShaderArchive

[winged moss]

where are you looking?

what's in your Content folder?

[frail hornet]

im trying to cook my image files in ue5 like you could in ue4 from png to uasset/ubulk/uexp

im looking un saved/cooked/windows/"the name of project"/content

UATHelper: Packaging (Android (Multi:ASTC,DXT,ETC2)): Z:\app\src\main\java\com\epicgames\ue4\GameActivity.java:570: error: cannot find symbol

[odd iris]

Hi everyone, hope this is the right channel:
I'm using Gitlab to build an UE5 project (Windows, Linux, Linux Server). When packaging, I don't get any errors, but on windows build only, the resulting packaged artifact doesn't have the .exe file in the root directory. The binary in Projectname/Binaries/Win64 exists. On linux, these are small shellscripts that call the binary in Projectname/Binaries/Linux, so I'm assuming the .exe that is missing would do the same.

[verbal cargo]

Hi

I added PublicDefinitions.Add("UE_ALLOW_MAP_OVERRIDE_IN_SHIPPING"); in ProjectName.Build.cs

but my shipping build still doesn't accept launch params

[verbal cargo]

if I add it to GlobalDefinition in ProjectName.Target.cs i get this error packaging project: modifies the value of GlobalDefinitions. This is not allowed products in common with UnrealGame.

[winged moss]

you will need a source build if you are modifying GlobalDefinitions

[verbal cargo]

what you mean?

[winged moss]

an engine source build

I don't know what's ambiguous about that

[verbal cargo]

ah, i have only the project source

another way to set UE_ALLOW_MAP_OVERRIDE_IN_SHIPPING?

in GameInstance.cpp there is that precompiler if

#if UE_BUILD_SHIPPING && !UE_SERVER && !UE_ALLOW_MAP_OVERRIDE_IN_SHIPPING && !ENABLE_PGO_PROFILE
    // In shipping don't allow a map override unless on server, or running PGO profiling
    Tmp = TEXT("");
#endif // UE_BUILD_SHIPPING && !UE_SERVER && !UE_ALLOW_MAP_OVERRIDE_IN_SHIPPING && !ENABLE_PGO_PROFILE

my goal is to have shipping build that accept launch params

It works fine in the editor when I first create the assets, up until the point I try to reload the project or package the game. Does anyone have advice?

HALP! Got a game fully built and well, downloaded the code onto a MacBook and pressed compile. It's crashed twice on me already and is using over 100GB RAM before crashing. PC compiles Windows and Android just fine. How can I fix this memory issue on the Mac build??? MUCH APPRECIATED!

[frail hornet]

when i cook content for windows why is it only giving me shader archives

[indigo ravine]

It seems sometime since March, Apple started requiring their apps to use SDK 16.1 in order to be uploaded via Transporter. 16.1 is only available in XCode 14.1 or newer, but UE5 currently cannot build with XCode 14 (need to use 13). Has anyone heard of a potential fix for this? I can't upload builds for testers anymore until this is resolved...

[gaunt lava]

I understand that pak file does not contain the binary files so, is there a way to dynamically load a separate Unreal module to a separate packaged build? as a dll? (more like c++ mod support)

For the example use case, I made a TestActor as cpp and made a blueprint class from it, but as soon as I load its pak from a separate build that is created prior, I will get an error as the c++ file is not included. Is there a workaround for this?

[crisp otter]

Hello, I want to add the Visual Studio c++ Runtime to my build so the users don't have to install it, I've seen that I can add it in the Game Prerequisite Installers, but I'm not sure how

[remote haven]

Hey has anyone ever had bugs that happen in a build but not in the editor, or only intermittently in the editor?

[vale birch]

Does anyone know how to solve the error "Failed to open Descriptor File"

[summer dock]

rare, but they do happen on occasion

[remote haven]

I've been fighting with my inventory not populating in build for a few days, but it works fine in editor.
An earlier blueprint version works all around, and then I moved some of the heavier functions from UMG into a C++ super class and now none of the items will show in build.

I was just wondering if there was anything I should look into as maybe I've made a small, very dumb mistake somewhere

[summer dock]

Hard to say... adding lots of logging / on device debugging is the only advice I can come up with

[remote haven]

No worries, thanks. I'll keep trying to debug, and maybe just move stuff back over till it works or something.

I've copied everything to code pretty much exactly, and Debug Messaged on screen at pretty much every step, and it should work, they're just not showing on screen. I'm stumped

[summer dock]

I guess I might sanity check a couple of things like

• are the widgets created ( as in they certainly exist, just not visible )
• are z-orders correct ( not going under stuff )

[remote haven]

Thanks, I appreciate it! I'll look into those.
In the process of reverting to the blueprint versions just to see if it'll work again.

Might slowly transition the functions to see at what point it breaks, because I don't know what else to do at this point

[summer dock]

Yeah, that's a good angle to take as well

[remote haven]

Finished the revert, and the build is fine again. When I find the issue I'll try to mention it here if I remember

Hi! Does anyone know why it fails when I try to package for android? 😦 https://pastebin.com/iiMyxbaw

[lapis cave]

For anyone else that comes across a similar message when they attempt to package. This was caused by some legacy cascade particles that were being used. After removing them from the levels and BP's they were in, the game packaged fine.

Build your project modularly: https://unreal-modding-library.github.io/dev-guide/Basis/C++.html#building-modularly

[gaunt lava]

Thanks for the link, really appreciate it!

I was actually figuring around this way as well. For quick testing, I am using a blank project and a 4.26 version of the engine pulled from github, but I am getting a bunch of linking errors when I compile Development config after setting my TestProject.Target.cs to modular.

but I can see the plugin dlls being generated though

Also, how do I exactly load the "plugin mod" with this DLLs? As for the pak files, I mount it.

[torpid night]

Having an issue where attempting to package or cook is failing due to an erroneous CPP on line 21, which is now only 17 lines. Yes it has been recompiled, rebooted, etc.

Edit: Further information, Deleted the source cpp/h from project dir, same issue pops up, referencing non existent code on non existent files.

[hardy inlet]

I am having a very strange bug after packaging where all of my in game blueprints are duplicated on top of each other. It’s a simple platformer with collectibles and enemies, and they are all doubled. Any ideas?

[pale chasm]

There is a built-in engine feature that allows the game to try to mount all plugins from ProjectDir/Mods automatically, including their pak content, their configs and their module DLLs as described in the mod's .uplugin file.

[gaunt lava]

that's interesting, I'll take a look on that. Thank you!

[woeful thistle]

Someone help please. Unreal's complaining at me with this but I have 0 clue what it wants me to do

Your CPP class is missing.

[woeful thistle]

I don't ever remember making that class

🤦‍♂️

Okay I've made one based on the AssetManager class but do I need to put anything in here?

[mystic atlas]

No.

You might consider what is still referencing it if it doesn't exist.

[woeful thistle]

Now what. I hate this so much.

Found it

Looks like you had an invite class set as your asset manager.

Hello everyone 👋、just checking in to inquire as to if anyone has had success launching a UE5 .apk on an Android tablet device?

I have been struggling for over 2 weeks now to do so, as any packaged .apk on my Lenovo M10 HD immediately crashes on startup.

Clearing the tablet cache and reinstalling said .apk also leads to no avail 💦

Any and all recommendations and input would be deeply appreciated at this time. 🙏 Thank you for considering my inquiry.

[grand shadow]

Hello, 👋 I achieved success with fully packaging android apks in numerous versions via this recommendation:

https://forums.unrealengine.com/t/unreal-5-1-package-project-for-android-error-org-codehaus-groovy-vmplugin-v7-java7-and-java-lang-unsupportedclassversionerror/793309

However, I now face the issue of being unable to launch my apk on my Lenovo tablet device. Step by step the process continues I suppose. 🤔

[grand shadow]

As an update on this previously posted inquiry, I discovered an experimental plugin known as 'Color Correction Regions (CCR)' within UE5.1 that was causing the shader compiler errors to pop up while attempting to build a mobile device preview or an APK file. Disabling the plugin resolves the issue.

Hopefully, this information will be helpful for others who may encounter the same or similar shader compiler issues.

Onwards and upwards.. 👍

[summer dock]

MacMinis are often the preferred build machine : small and compact. Stick it in a corner, setup Jenkins/TeamCity or something similar and let it do a test build on every change "monitor" and a daily build which is piped to Testflight "nightly".

[coarse citrus]

thank you so much! never ever knew about minis being a thnig and it is more affordable if I just need it for packaging to macOS...
I wonder is ram necessary for increasing packaging speeds? or just CPU cores?

[summer dock]

not sure. we have a 2020 m1 and it does the job. Hard drive space is a problem if you have a source fork of the engine, but external drives can help there.

[coarse citrus]

Yup already have external drive for source build, so space won't be an issue I guess I will just get the cheapest mini I can find since the core difference compared to the prices doesn't justify spending more

thanks again

[proud river]

Is my packaging done or still packaging ?
this screen is like that from quite sometime now

[open rapids]

can you guys help

?

[proud river]

it's been 6 hours still packaging..

my game size is 1.11GB

[proud river]

must be SDK, JDK issue happened to me for weeks until i figured it out

[lost musk]

(im new) is packaging the word to use when I am sending out a game to my friends to test

[summer dock]

packaging is the process of creating a build : distribution / deployment are common terms for sending the builds out into the wild

as there is no specific channel for that sort of thing, I guess this is close enough, or the platform channels for platform specific issues

[lost musk]

is there a way to have my friends test it without "packaging" not sure if it affects the process but it would be a multiplayer game

[summer dock]

packaging is easy, press a button, wait a while, you get a folder with a .exe file and a bunch of other stuff. Zip that up, put it on google drive or similar cloud and let your friend download and try it out.

for multiplayer, you will need a lot of stuff. If this is your first stab at gamedev, I do recommend starting out by making a couple of small singleplayer games before going for multiplayer.

[lost musk]

the main reason I'm doing multiplayer first is because I assume if I want to change it later or use the same assets for another project I would have to completley redo the blueprints/code

[summer dock]

Well, there is some truth in saying if you're going to do multiplayer it is best to do it from the beginning. That said, the blueprints and code one makes in the first year of learning are often pretty rough stuff. In any case, if you design nicely encapsulated actors / features / ui, reusability is generally not too bad.

But now we digress from the packaging theme of the channel

[lost musk]

understandable thank you for the insight. when it comes to packaging should you keep it to google drives until its really close to being ready and then switch to sending it to steam/epicgamestore and just doing updates?

[summer dock]

I often start with a gdrive/cloud deployment, but once you have a solid playable then it's definitely time to start setting up the proper channels. For your first games I wouldn't stress too much, but as you go on you will want 1) to set up version control, even if you are solo and 2) to consider if you should set up Jenkins or similar to start making nightly builds and automate uploads to providers

.... I had SteamVR as a module in my build.cs... I dont use it

[young shale]

I load two images using LoadObject. One of them is included as an expected and the other is not. Is there a way to force an asset to be packaged?

[winged moss]

you can force a specific directory. if you have a UPROPERTY of the image somewhere (can be soft) then it'll get packaged

[young shale]

So a Uproperty of a UTexture2D would work?

[winged moss]

yes or TSoftObjectPtr<UTexture2D>

[young shale]

I am trying that. If Strong doesn’t work I will try soft.

[winged moss]

a LoadObject call is pretty redundant if it's hard ref'd

[young shale]

I loadObject to create the strongObjectPtr

[winged moss]

then that's the problem, and not the solution I was suggesting. in the Blueprint, you would set the default to the asset

then the cooker knows it's referenced

[young shale]

This is all in cpp

[winged moss]

well it's generally bad to do asset references all in C++, but you can have a UDeveloperSettings class where the image can be set in the editor, that can be found by the cooker

[young shale]

So in theory I should just be able to set the references in that class and that will force the assets to package so I can just do my old workflow, which is only failing since the assets are not packaged.

[winged moss]

the nuclear option is to use the "directories to always package" option in the packaging settings, but this can't be done for individual assets

but with the UDeveloperSettings, the cooker will be able to read those and they would get packaged

[young shale]

I think I will try that first. It is dumb but my workflow is already dumb and this is due tomorrow.

[winged moss]

or having a data table with the images in it and setting a reference to that

just as long as it's directly referenced

[young shale]

It works now. I used the packaging options to package everything in the content directory. Luckily I am working on a small project with basically no assets so this isn’t a performance night mare.

[young shale]

Thanks again!

[grand shadow]

Thank you for sharing 🙏👍

[tight iris]

Add a line to your Applicable config file (Like DefaultEngine.ini):

+DirectoriesToAlwaysCook=(Path="")

Inside the quotes put the directory you want to include.

can anyone help me?

[vivid lotus]

That's not quite what I'm asking, the mesh asset itself is being packaged just fine and exists on both the client and server (I was referencing it via a uprop), the problem is more advanced than it just not being packaged, the client and server get different versions of asset, in the instance of 3D assets, the render data of the mesh is typically ommitted from the servers "version" (since servers don't and can't render anything, the cook system drops it to slim down the total size of the dedicated server package)

[tight iris]

Oh that is interesting. Sorry. Thank you for correcting me though. That is very important to be aware of.

[small wren]

Has anyone ever ran into an issue trying to package a game if you renamed a module? Core redirects are working for the class names, but the old module names are erroring out the cook process:
LogStreaming: Error: Couldn't find file for package /Script/OldModuleName requested by async loading code. NameToLoad: /Script/OldModuleName

[vivid lotus]

Are you just redirecting classname and not the module too?
+ClassRedirects=(OldName="/Script/MyOldModule.MyOldClass",NewName="/Script/MyNewModule.MyNewClass")

There is also a game redirect, that can redirect the whole module, but it'd need to dig around to find it, doesn't seem to be mentioned on the Core Redirects page

Ahhh, here we are, found in one of my older projects' DefaultEngine.ini

[/Script/Engine.Engine]
+ActiveGameNameRedirects=(OldGameName="OldModule",NewGameName="NewModule")
+ActiveGameNameRedirects=(OldGameName="/Script/OldModule",NewGameName="/Script/NewModule")

EDIT: Found it on the 5.0 documentation, seems it's deprecated and CoreRedirects was what replaced it, so if you're in 5.0+ it may or may not work as expected.

[odd junco]

is it possible to break up a level into small pak files? getting a error saying my level can't fit in the pak size I have set and i don't really want to increase it.

[empty ledge]

Hello everyone, someone here already uploads a game on Steam, i don't know how to "Check" this box "Store and Dev Comp Packages Match" here:

[small wren]

I've tried both those methods. The first one you mentioned is the one we've been using, and the classes redirected just fine. The game builds and runs fine, up until we try to package it for Android or iOS. Then we get the cook error I mentioned above where it is only complaining about the old module name.

[vivid lotus]

If you're getting it to run fine with those options applied, what you'd want to do is resave all blueprints and then try to package, that will update (permanently) the module and classname so you can remove the options from the config, just resave the folder with the majority of your blueprints in for a test and then try packaging again

[small wren]

I just realized I can package the same code on a different machine just fine. There must be something cached somewhere thats causing the issue?

[vivid lotus]

I would guess there's something like that going on, yes

Anyone know a fix for this error? I get it when trying to export my project to IOS..

[icy tartan]

Hi,
how can I change SaveGames directory from AppData to Package directory?

[past portal]

hi, which version of visual studio should be used for packaging with 5.2 ?

You need to setup your branches and depots

Wonder if anyone could shed some light as to why I get a hefty FPS drop after a default 3rd person template is packaged please.

120 FPS in the Editor but barely 40 on a packaged template.

I,m wondering if this is related to my PC being slow (i7 8700k 48Gb DDR4 3200MHz, running on a 970 Evo 2TB and a GTX 1070ti) , Only posted specs here as I dont know if it,s relevant, (Monitor is a MSI QHD Monitor 2560/1440p), The only thing I added was a Widget showing FPS as the Stats screen i could seem to show when i launcged the exe from packaging.

[summer dock]

That seems odd: generally editor should be slower than packaged shipping builds. Dev builds I'm not so certain of

[vivid lotus]

I typically get 3x the FPS in a packaged build, shipping or dev, @scenic kindle what do the engine stat commands show/say? Enable stat fps and stat unitgraph from the console (using the ` key)

[scenic kindle]

This is the stat fps

unit graph

Sorry for the late reply, Had some stuff to do thank you all for the replies. 🙂

I'm trying to debug a GPU crash that happens when I play my exe, can anyone help me to figure out how to actually get the gpu crash information using this command? I tried running it in the shortcut but couldn't tell what changed / where the gpu crash logs ended up

[scenic kindle]

Anyone got any idea on the low performance of the Third Person Template when packaged please ? I found the GameUserSettings.ini file and changed all the values from 3 to 2 and it increased from 40-60 in the package version but does this mean that you need to have all settings at 1 for it to be even half useable?

[scenic kindle]

For anyone wondering I think I might have solved my issue or at least figured it out.

sg.AntiAliasingQuality=2
sg.ShadowQuality=1
sg.GlobalIlluminationQuality=2
sg.ReflectionQuality=2

sg.EffectsQuality=2
sg.FoliageQuality=2
sg.ShadingQuality=2

bUseVSync=False
bUseDynamicResolution=False
ResolutionSizeX=2560  (When this is set to 1920)    
ResolutionSizeY=1440  (And this is set to 1080) I get fixed 60FPS 

So it seems it might be my hardware not being powerful enough to run the template at 60FPS @ 2560 x 1440. (@2560 x 1440 I get 40 FPS (ish))

As a test I exported a Third Person Template from 4.27 and it runs at 1440p at 60FPS so not sure whats causing the FPS drops in the UE5 version of the template maybe it,s more demanding on my 1070ti. 🙂

[wooden elm]

Hey folks, not 100% packaging but it is project related and hoping someone can help me understand whats going on. I am using UE 5.1.1
I have say a Uasset in its corresponding folder, each asset then has multiple copies with strings of letters after them.

For example: uasset~K94AJ93K

This means nearly every asset in my project is quadupled pushing my project size to nearly 1 TB!

What are these duplicates? And What should I do about them?

[lost musk]

I think im finally ready to package and test my game with my friends anyone have a link to somwehere i can learn how to do it there is nothing in pinned

[vivid lotus]

@lost musk Take a simple google of "ue5 package project" and you'll find a million examples 🙂 the first link is from Epic Games themselves, or try one of the top videos that google will suggest, if you prefer a video tutorial

[vivid lotus]

Since you're not seeing the same issues in a UE4 template, my best guess is that it's Lumen being on by default, even on my system, with a i9-7920x and a 3090, I get nearly twice the performance, just by turning Lumen off, I can only imagine on older hardware it'll also make a difference.

Go to Project settings -> Rendering and change the following options
Global Illumination -> Dynamic Global Illumination Method = None
Shadows -> Shadow Map Method = Shadow Maps
Reflections -> Reflection Method = Screen Space

[lost musk]

damn i packaged it and cant get past the mainmenu

[lost musk]

alright so my game works perfectly within UE5 but when i package it and try to open it my button for starting a solo game doesn't do anything and my host game doesn't do anything. I assume the multiplayer thing has something to do with subsystems but i have no idea why the solo game button all of a sudden doesn't work when i package it.

[wooden elm]

Might sound stupid, but did you make sure to select all of the maps needed for the final game when packaging?

[lost musk]

under default maps I selected my main menu map for both options, is there more im supposed to do? I do have some code that takes me to my gameplay map on a button click but that only works when im in UE5

[hybrid hare]

anyone know what this could be

it pops up right when i package my projec

its the only thing stopping it from packaging

[winged moss]

Show your primary asset settings under the Asset Manager section

[hybrid hare]

Alright

One sec

Where do I find that?

[winged moss]

Project settings. You must have configured it at some point to get this error

[hybrid hare]

Broooo

Thank you

I litterally seen the issue right when I went in there

I’ve litterally been banging my head at this all day

[wooden elm]

Yes when you package your game you have to select all of the maps you need for the game (not just the ones under project settings) I use the package launcher to do my packaging and under there you just select all the ones you need

[lost musk]

I cant seem to find the package launcher, is that a plugin?

[vivid lotus]

Does anyone know if there's a way to include a copy of a client build's mesh in a dedicated server package? (Without just copying the pak file over to the server build)

I have a mesh that I need to access the section data of at runtime (using UKismetProceduralMeshLibrary::GetSectionFromStaticMesh()) and the data being retrieved within that helper function is empty on a server, resulting in a crash.

...

I can't figure out how a 5.1 engine feature isn't "available" for windows packaging

[mellow atlas]

I think you just need to add the module to the dependency if it is c++

if it is BP, then it should has been enabled in plugins already

is weird tho, you couldn't compile the game first hand if that is the case!

[terse current]

yeah idk :/ it's complaining about the actual input actions themselves

these things

[mellow atlas]

BP or C++?

[terse current]

i dont think it can be raw c++ can it?

[mellow atlas]

I mean the project, do u do the binding in c++ or BP?

[terse current]

oh, c++

and it works fine when I run it. it's just the packaging that refuses to work

[mellow atlas]

make sure to edit yourpeoject.build.css and add the dependency

otherwise u might be missing a header include

[terse current]

the c++ compiles fine though, it's the raw files of the input actions and the mapping context that it claims dont work on windows

[mellow atlas]

yeah, that is what is weird

you have both

#include "EnhancedInputSubsystems.h"
#include "EnhancedInputComponent.h"

?

[terse current]

for the file that does the mapping?

[mellow atlas]

yes

[terse current]

it says it'd be unused, but I can try it

same issue

[mellow atlas]

I see it is rider, but what I learned so far is that, don't ever trust the IDE when working with Unreal c++ lol

[terse current]

:/

[mellow atlas]

oh, u have separate modules for your game, not all files in the default module?

[terse current]

wdym?

I don't think so?

[mellow atlas]

double check if the dependency included isn't in an if statement in the build.cs, maybe it is included for specific platform

[terse current]

public class FlightAimTrainer : ModuleRules
{
    public FlightAimTrainer(ReadOnlyTargetRules Target) : base(Target)
    {
        PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
    
        PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "EnhancedInput", "RD", "SlateCore", "ApplicationCore", "Slate", "UMG" });

        PrivateDependencyModuleNames.AddRange(new string[] { "RD", "GameplayAbilities", "GameplayTags", "GameplayTasks", });

        // Uncomment if you are using Slate UI
        // PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });
        
        // Uncomment if you are using online features
        // PrivateDependencyModuleNames.Add("OnlineSubsystem");

        // To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true
    }
}

[mellow atlas]

hmm, I don't have other suggestion sry, lets see what others may come up with

[terse current]

perhaps it's just a bug with 5.1.1 :/

im trying to package it on 5.2 instead and it's made it a lot farther

[mellow atlas]

haven't encounter such bug yet, even after upgrading to 5.2

I'm having some issues with enhanced input myself tho lol

but it is related to possessing in multiplayer

[terse current]

i havent had any issues with the inputs for multiplayer yet with enhanced, it was mainly just replication shenanigans that took a few hours to iron out XD

[mellow atlas]

yours automatically posses on spawn? or afterwards? I know I'm being stupid in my case and hopefully I will figure it out soon

[terse current]

yep, auto on spawn

[mellow atlas]

ic, different situation here then, but that is for another time, lets focus on your issue

[terse current]

same issue again on 5.2 :c

[mellow atlas]

what is that Script folder? just an organizing folder? or what?

[terse current]

it isnt mine

[mellow atlas]

as a last resort, try recreating those mapping and actions, with different names then use the new ones, keep the old ones for reference and backup, they might be corrupt or something

[terse current]

just tried that

[naive ridge]

In which class you are including the enhanced input headers?

[mellow atlas]

I know stupid suggestion since the game runs normally, but who knows 😄

[terse current]

didn't work :/

[terse current]

an actor class

[naive ridge]

Can you show me the class by the way?

[terse current]

not particularly, it's fairly lengthy

[naive ridge]

Just wanna check the declaration of the class

[terse current]

UCLASS()
class FLIGHTAIMTRAINER_API APlayerShip : public ABaseShip
{
...
}

with the base ship being..

UCLASS()
class FLIGHTAIMTRAINER_API ABaseShip : public APawn, public IAbilitySystemInterface
{
GENERATED_BODY()

[naive ridge]

So this one is the main game project module?

[terse current]

think so?

[naive ridge]

I'm not sure but would you like to try reparent your ABaseShip from APawn to ACharacter?

[terse current]

i doubt that'd do anything except bloat it some more lol

but i'll try it

[mellow atlas]

while at it, close everything after the edit, and regenerate the solution, and build again from the IDE, then close the IDE and closing the editor then reopen the editor only and package

[terse current]

reparenting did nothing

[naive ridge]

https://forums.unrealengine.com/t/recompiled-for-mac-but-cant-package-failed-to-cook-it-imports-class-which-is-in-a-module-that-is-not-available-on-the-platform/717254
Looks like someone has the similar issue but still no answer.

[mellow atlas]

u r packaging for windows from mac ?

[terse current]

no

guess the only major thing left I can do is just try a fresh project and slowly rebuild it until it breaks lol

[mellow atlas]

😮

[naive ridge]

Maybe yeah, the last way is trying delete all the intermediate folders, lol

[terse current]

already did that

[naive ridge]

And turn off unity build?

[terse current]

not sure what that is

[naive ridge]

bUseUnityBuild in target

[terse current]

so bUseUnityBuild = false then?

[naive ridge]

For your project, don't do that for the whole engine, or it will take you half a day, lol

[terse current]

wellp it's gotta be in my code somewhere

so I guess I'll just get cracking on that then, the fresh project built with some bogus input actions/mapping contexts

[naive ridge]

So the thing I'm suspecting that somewhere referencing the enhanced input module which is not supporting blueprint somehow.

[terse current]

oh

that could be an easy fix then

just make it blueprintable right?

[naive ridge]

I'm not sure but you can give a try.

It looks like it.

[terse current]

yeah that didnt work either

:/

[naive ridge]

Where did you references these assets? I mean which classes except for the character

[terse current]

thats it :/

[naive ridge]

That's outrageous.😅 No idea why it is not working.

[terse current]

got it built

wasn't a code thing after all

just a psa for anyone that might be dumb like me, don't have this.

needs to be this instead

[naive ridge]

Didn’t you add it by check the box in Editor?

Usually it will add all platforms you are supporting.

[terse current]

nah I think i copied it from a different project i made a while ago

[violet tundra]

I have a persistent level that covers other levels. When packing the game, is it enough to choose only this persistant level or do I have to choose the levels below it?

[wraith wadi]

I figured it out. The problem is I was using the name of the Mac in Unreal Engine Settings in "Remote Server Name". I need to type the IP Address there and generate the ssh key for it. I thought it is just for the ssh connection and ssh works with either of them, but Unreal requires the IP.

[wise robin]

How can I tell a packaged game to default to high scalability settings and screen percentage 75? 🤔

I've found something about adding a defaultscalability.ini but there's nowhere that says what to type to force a specific scalability setting, most people just say to copy the baseEngine.ini but that simply has a configuration of what each level of settings should have not what it should default to

[silver kraken]

Trying to debug this strange packaging error that comes up ... project has been packaging just fine from day 1 - added in a few plugins - OnlineSubsystemSteam, AdvancedSessions, AsyncLoadingScreen(Engine) and now i'm getting this weird package error i dont make sense of:

this is like a FRESHLY INSTALLED/compiled 5.2 source as of about 1 day ago.

[silver kraken]

I see that AdvancedSessions and OnlineSubsystemSteam are littered with public I... classtypes - i'll presume this is it but i dont know how to fix the packaging errors.

[undone ravine]

How can I optimize the size of my packaged game? My previous released version was about 40GB packaged, and the map "builtdata" objects were most of it. Most of that was probably lightmap data, so I reduced the size of my lightmaps. I probably reduced those "builtdata" packages by 40% pre-packaging, but my packaged game is only reduced in size by 5GB. I have no idea what on earth is using up the rest of my package, but I'd love to know.

Part of the issue is that once my data is packaged I have no idea what is actually in it and what size it is after being compressed

Theoretically the engine is only packaging what I need, but there might be stray references that is causing a whole lot of other junk to also be included that I don't want.

[naive ridge]

First of all, I think you need to check any assets in developer folder got referenced outside of it.

[mystic atlas]

You can also look at the pak file to see what's actually packaged in it.

[mellow atlas]

if u build a game with a completely empty level without anything at all u end up with over 2.5GB packaged game, so a game that shows a black screen will have that size 😦

[mystic atlas]

Depends what you do to it.

You can get the mobile version down to about 50mb.

[naive ridge]

And you might use a tool to check the 0 referencing asset and delete them from the project

[undone ravine]

But how though? Especially in the compressed package

[naive ridge]

You still have unreal basic stuff packed and cannot avoid that

[mystic atlas]

I was curious myself and found this: https://github.com/tshao4/UnrealPakGUI

Never used it before, so use at your own risk etc.

[mellow atlas]

the build system should check for that, we can have 1 TB of asset, none included in the game in any way, why including those in the package?

[naive ridge]

By the way, I remember you can choose if package it as a .pak or with all the assets there not in only 1 file?

There's one option in the settings.

[mystic atlas]

You can turn off pak'ing, yes.

So that's also an option.

[mellow atlas]

nothing referencing them, but anyway, let me stay away of that, lets get back to main question 😉

[undone ravine]

Sweet, thanks. I'll check this out

I did try just building it without packaging and compression, but it seemed to be extremely wasteful with size, and I assume certain things can't be compressed, like lightmaps that are already compressed, while other things will compress a lot so in my opinion it's not easy to infer what is actually using your space up

The uncompressed unpacked build was like 150GB, so yeah..

[naive ridge]

That sounds crazy dude😆

Wonder how many assets you tossed into the game.

[undone ravine]

Well considering it's about 50% of Titanic It's quite a lot. It's done fairly messy too so there is a lot of optimization possible. However, I was certain most of my data usage was lightmaps, so that's why I'm confused why I'm not getting hardly any disk savings after reducing my lightmaps by approximately 40%.

[mystic atlas]

Oh you're the Titanic guy!

[naive ridge]

That's you!

[undone ravine]

Thatsa me

[mystic atlas]

Try packaging your game without pak files and see what happens.

[naive ridge]

So maybe you can try more dynamic lights? I'm not sure your titanic needs to be run on 60 fps or not😛

[mystic atlas]

60 fps, but only 1 ips (icebergs per second)

[undone ravine]

So I reduced the size of the level folder from 42.5GB to 25.6GB between the previous released build and the current one. Since that is mostly compressed lightmap files, I expected the file size reduction to be roughly linear. But there is only a 5GB reduction.

I am repackaging the project without encryption and without pak files but still compressed to see what the size looks like, and I'll see if I can figure out what is actually taking up space

[mystic atlas]

Good luck!

I guess optimising package size is... a sink or swim issue.

[naive ridge]

If your size is filled mostly with lightmap, there's few things could help.

[undone ravine]

It's 150GB without paking, so not sure how I'm supposed to get anything useful out of this

[mystic atlas]

Find out where the 150gb is residing.

I'm assuming the files are identifiable.

A program like windirstat might help. I'm not sure the format it will have used.

I.e. where the files are placed.

[undone ravine]

The maps folder is 123GB

I don't understand why, but some levels have actually inflated in size by a lot

[mystic atlas]

Find the biggest offenders and see what's there!

[undone ravine]

The one built data file before packaging is 1.1GB, but in the built package it's 9.5GB

[mystic atlas]

You might be able to use the asset tools to get a list of the contents of the map package.

And its corresponding size.

So this packaged fine in a fresh/new project with 0 code implementation and just the plugins.....

Ive added in a ViewModel to see if theres some mishap there.... due to the original error code in the build - and sure as shit this new project it came up with as well.

All i've done is added to the build.cs - "ModelViewViewModel"
and created a file MyViewModel.h with some attributes in it - not even bound to any attribute set or anything....
Added a UI in the project that has 1 value bound to this ViewModel - and got the same exact error for packaging:

Hello everyone

I'm getting an error when packaging

Object reference not set to an instance of an object

Here's the log

[terse verge]

game doesnt open anymore

packaged this project like 3 times already and its been fine, now it just does cursor loading icon and nothing happens

I just added some advanced session plugins before latest package

yep of course it was the plugin

not sure if I need it, not sure how to fix it if I do need it, nobody tells me anything and unreal isnt being very helpful with it

[summer dock]

Unreal is frankly a painful engine, demanding, poorly documented ( the source code is the documentation, really... ) and with a much much smaller community than f.ex. Unity. If you feel it is too much, you might consider trying something a bit easier... But there's pain everywhere, so if you have already made inroads and are liking it, then... pain is fun!

[silver kraken]

I literally went through a bullet list of plugins today and packaging and can tell u advanced sessions is fine.

[terse verge]

I wasnt blaming the plugin, I just didnt know what I was doing wrong

its fixed now, but still cant get any of this multiplayer working at all. hosting and joining works fine in the editor

[terse verge]

yeah Ive been using unreal for around 6 years, never been a coder so dont really have any other options

[twilit yacht]

Does anyone have resources or tips for doing Dedicated Server builds for an open source project on github? I know they require engine source to build, so I'm wondring how to make a github action work 😦

[undone ravine]

So I managed to get it down to 28GB, so I think I'm happy with that for now

[mystic atlas]

What did you have to do?

[undone ravine]

Oodle didn't seem to be turned on properly. Then just turned up all the effort levels on the encoder. Also manually excluded my DEV folder which has a bunch of extra junk I don't actually need.

[mystic atlas]

Heh

[undone ravine]

Oh, and enabled share material shader code and shared material libraries

I think there is a lot of room for improvement to make this more user friendly. At a minimum, some kind of tool to let you audit the size of assets after you built them, even a shipping build that is in an encrypted .ucas file

[tight iris]

GitHub actions would cost a fortune to build UE once, I think. You'll want to build yourself it is not hard.

[wicked rampart]

I would suggest setting up a build farm on EC2 🙂

[twilit yacht]

got it, was worried the answer was trending this direction. thanks for the feedback, will start figuring out a plan 😅

[viscid girder]

hello, i used to build my project using cmd /c "GenerateProjectFiles.bat %AVALONHOME%\Avalon.uproject" to generate the project files first

but that .bat file seems to have gone

is it only included in the source code?

[mystic atlas]

Yes

I think?

Just right click on the uproejct in explorer and do "generate project files"

or replace "generateprojestfiles.bat" with the unrealversionselector.exe file that might do it?

[fast skiff]

Hi everyone, i packaged my project and when i launch it theres an error showing up:

Assertion failed: RenderSection.DuplicatedVerticesBuffer.DupVertData.Num() [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Engine\Private\SkeletalMeshLODRenderData.cpp] [Line: 198]
What does this mean and how do i fix this

[mystic atlas]

I think it means one of your skeletal meshes has duplicated vertices

I.e. 2 vertices in the same location.

[jolly nymph]

Any way I can force my users' user settings config to reset towards a new build?

Perhaps increment some version number or whatever that would do it automatically?

[mystic atlas]

You could change the name of the class.

UE supports versioning, but it's a little weird imo.

Hello, I am trying to get the plugin version in a batch script, i have a feeling someone is going to say, use python, but all i need is something like RunUAT -plugin=x.uproject get_version

then i can simply set the version in the script as part of the build output location

[winged moss]

what is even going on with your build automation with all these questions? like you don't even need a project file to do a build, and with this, this is likely a string inside the uplugin file which is JSON, though the screenshot is overcropped so I don't know where you're reading that from

[viscid girder]

I am just struggling to find a way to get the version info from the build tool, i've wrote a python script in the end to read the .uproject file

[winged moss]

"from the build tool" refers to what exactly

[finite pebble]

help please!

cant build my dedicated server anymore and i dont know why .(

[winged moss]

if this is the Epic launcher engine, then you've never been able to build a dedicated server

[finite pebble]

well its not its from a source build but im building thru the editor

[winged moss]

ok then that's never been supported, ever

[finite pebble]

huh ? meaning waht

[winged moss]

to compile a dedicated server, you need a source build. that's remained unchanged since the very first UE4 release

[finite pebble]

but but

yeah thats what i did the first time but i can "rebuild it " or recombile it via the editor

i just followed a tutorial and it has worked fine untill now

The Binaries Folder in the projekt folder

will it rebuild if i remove and reopen the program ?

[winged moss]

what? there's no ambiguity here, you need a source build to make a dedicated server

[finite pebble]

https://youtu.be/ad5MZLSDAZk

this is what i followed

[winged moss]

and that tutorial is using a source build

[finite pebble]

yeah so thats what im using also^*

(im new at this obvi)

[winged moss]

well I kinda misread your message I suppose. you may have done an installed build (I much prefer native projects for source builds) but excluded dedicated server support

[finite pebble]

oh i suppose so idnno i just gave it a wack and it worked

untill now

[mellow atlas]

are you sure you downloaded the source from github? the Unreal source code

[finite pebble]

yeah

199%

100*

it wont let me build in c++ anymore either

[mellow atlas]

kk, are you sure you are targeting that source build in your project? not another version you have downloaded from the launcher?

[finite pebble]

hm

dont remeber how to check that

[mellow atlas]

right click your uproject file then switch unreal engine version

make backups before messing with anything if you are deep in the development

[finite pebble]

aye i have backup

so i cna select the 5.1 or the sourcebuild

i suppose i want the source build right

[mellow atlas]

yup

[winged moss]

I hope by a backup, you mean source control

source control is a backup, but a backup isn't source control

[finite pebble]

nope dont have source controll

[winged moss]

well that's stupid

[finite pebble]

but i have external harddrive that i just transferd the project from 2 days ago

yeah well unable to connect my project to github for some reason so..

ok so rebuilding now with the source version

and the build got longer but still failed

@mellow atlas

[finite pebble]

oh

yeah

just saw it

lol

[winged moss]

use UFE or use BuildCookRun from the command line

[finite pebble]

ok how do i do that or :/ X?

first time user bro

[winged moss]

UnrealFrontend and BuildCookRun are googleable

[dark echo]

Find that exe in \Engine\Binaries\Win64

This is the unreal frontend. It will allow you to create a profile to get a build. In it you can select if you want WindowsClient and WindowsServer at the same time. It is better to do the build in the editor.

[winged moss]

by what definition is it better to do it in the editor? UFE runs the BuildCookRun UAT job, and so does the editor. At least UFE is less resource intensive to run

[finite pebble]

ah ok but will it help with my current problem ?

it says i cant do it while live coding enabeld

but ive disabeld it

[random helm]

Is it possible to use Custom Launch Profiles for packaging? does this make sense?

[mellow atlas]

don't just disable, close the editor, close visual studio, then reopen the editor and package, or run the UFE

[finite pebble]

okok

[winged moss]

do not disable live coding because it enables hot reload

[finite pebble]

meaning ?

[winged moss]

hot reload can corrupt blueprints. and since you willing choose to not try and figure out your Github issue, that should be an extreme concern to you

[finite pebble]

hmm alirght

ill have to look into that then lateron

but for now

i still get live coding is enabled blabla so cant build

even after restart

[winged moss]

then use UFE like suggested?

that can be run with the editor closed

[finite pebble]

hm ok

hm ok how do i use it

is there a tutorial or just simple instructions ?

dont wanna do something wrong

[dark echo]

Let's see, they are basically the same thing. But I have to admit that only the frontend eats me less resources than the whole editor and for me the interface is easier and more accessible. It's a matter of taste. But I have to say that for my colleagues (not programmers or with little experience) to configure a frontend profile and click on the button is more comfortable.

[viscid girder]

RunUAT that seems to be the build tool?

i just spotted something the version number for a plugin is in the .uplugin but in a .ini file for a main project

[zenith summit]

Our Perforce server seems to be out of service and it won't be fixed before tomorrow. Anyone know how to prevent a source control disconnection from breaking cooking? (Thanks, Epic.)

Why dosent this work 😮

the " log" function

[zenith summit]

Shipping build?

@finite pebble

[finite pebble]

no server

development*

[zenith summit]

Is it launching the executable but not opening a log window, or just not opening the executable at all?

[finite pebble]

i dont think its opening anything

i mean how can i tell ?

oh i could look at the task mnger ofc

[odd nest]

Any information on these two errors? They seem to go hand in hand but I cannot for the life of me figure out the issue, and recreating the entire blueprint and setting up references would take atleast 10+ hours. I am willing to try anything

[celest harbor]

hi, i'm trying to build server build from command line and was following this link,
https://nerivec.github.io/old-ue4-wiki/pages/how-to-package-your-game-with-commands.html

it worked for client build but for server build, batch file window just opens and quickly closes. i tried to run this batch file from cmd and
there it shows, 'RunUAT.bat' is not recognized as an internal or external command,
operable program or batch file.

i tried to rebuild automation tool of source version (using 5.1 source) too but still same error comes..

[zenith summit]

Edit the batch file to make sure you have the correct path to the folder containg RunUAT.bat.

[celest harbor]

oh, but if it is the case, for the client build command , the same error must have come but it packages fine with client build ..that's why i am confused

[winged moss]

it's not going to be anything but what was stated. RunUAT is a batch file, so it needs to be able to find that file

UE 5.1 android packing, unexplained error. Please help me with this.

[daring saffron]

is this a normal amount of time to cook? it is the first time cooking but it will take 5+ hours at this rate

[fast skiff]

First time can take a while

I am getting an error when packaging

PackagingResults: Error: System.NullReferenceException: Object reference not set to an instance of an object.
PackagingResults: Error: Unknown Error

I have been constantly getting this error

[fast skiff]

bruh a this point im ready to send my project to anyone who can package it lol

[winged moss]

That is not even close to the full error

[craggy fulcrum]

Hi all, hoping somebody has an idea why when I try to package with UE5.2 for Windows everything starts off great and then it just sits and appears to be building however no further progress is displayed in the log and it never completes the packaging. I let it run for 36 hours and it just sits and spins after a certain point. No errors or warnings, and the "packaging project" indicator is still showing with the little circle spinning away.

[dreamy sequoia]

36 hours seems like a very VERY long build time. Perhaps your PC is just very slow or maybe the project has TONS of unique content to process and it just takes a very long time or maybe your system run out of disk space? Hard to say what’s going on without seeing the log.

[plain lodge]

Hello. I'm using a new computer and when trying to package my game I get following error:

Anyone know what this is? 🤔

My game packaged perfectly fine before on my old PC

Could it be that I don't have the proper Visual Studios yet? Currently only have 2022 installed. Maybe I need 2019?

Having trouble packaging, anyone know why I might get the error "No matching platform for PakFileRules for Section ExcludeContentForMobile: Windows"

How might I fix this?

I'm releasing my demo on steam. Do I really have to write everything again??

Can't the demo page be the same as the main game page?

[lusty ivy]

Hi guys, does anyone know if it is possible to create a patch based on another patch using Unreal packaging? like i have _0_P.pak, how can I build on that and make _1_.pak

[winged jetty]

Good day to all! Who faced such problem? When starting the game on the phone, it crashes and gives this error.
LogVulkanRHI: Error: MapFormatSupport: R64_UINT is not supported with VkFormat 110
The strange thing is that when I download the game from the server, it works, but when I change something, it results in this error

[rare relic]

That's usually done by the distribution platform toolset, eg Steam. How are you distributing?

[lusty ivy]

I wanna know how to do with unreal

Its for art installation updates not distributed game

[rare relic]

Can't you just copy a whole new build each time?
Alternatively you could look at something like Butler tool by itch.io

[lusty ivy]

I can but its alot of gb and the network isnt always good at installation site for remoting

[clear plume]

I'm packaging a project at the moment, the content folder is about 1.8Gb but my packaged project is coming out at 2.5Gb, any way to optimise this?

I only have assets which are being used in this project and don't want to optimise my textures is there any other way to reduce the size of the packaged project?

[hearty wasp]

Staging directory option gone?

Also I don't have any build targets. So strange. Using 5.2 source

[scarlet pagoda]

When attempting to package for Windows, I get an Accessed None trying to read property on my GameInstance... I've checked for redirectors (there are none) and in DefaultEngine.ini, which appears to have the right location and BP. Anyone know of other things I can try?

New to unreal and trying to set up wwise. Project plays and cooks fine but fails on packaging.

Any ideas on how to resolve? The repo is https://github.com/sailor-snouts/wwise-test

I assume C:\Users\diabo\OneDrive\Desktop\wwise\Source\WwiseAudioLinkRuntime\Public should be C:\Users\diabo\OneDrive\Desktop\wwise\Plugins\Wwise\Source\WwiseAudioLinkRuntime\Public

[winged moss]

Only the last thing is an error

Odd if this is using the official plugin since that has Wwise in the Source directory of the plugin

Oh that's why. You called your project (or at least the game module) wwise

So it conflicts

[copper parcel]

ah thats probably why. Can I rename it or do i need to make a new one?

looks like more trouble than its worth, ill start a new project with a non conflicting name this time

[hollow thunder]

I have this line that I run,

C:\UE_5.2\Engine\Build\BatchFiles\RunUAT.bat BuildCookRun -project=D:/SanctifiOrigin/SanctifiOrigin.uproject -noP4 -platform=Android -clientconfig=Development -cook -allmaps -build -stage -pak -archive -archivedirectory="D:\SanctifiBuilds\"

and it gives this error,

ERROR: Could not find a project file C:\UE_5.2\D:\SanctifiOrigin\SanctifiOrigin.uproject.

I can't find any reason for this error, or anyone experiencing the same error. Any ideas?

[winged moss]

try quotes, using backslashes for the directory separator?

[hollow thunder]

I tried both 😭

[winged moss]

I've not not seen this work, but I've always used a source build

[hollow thunder]

Same, it just always seems to assume a local path

[winged moss]

see what command the editor or UFE generates, but it might set a different working directory

so having the project folder as the working directory, using the full path to the batch file, and passing -project as just the uproject filename

[hollow thunder]

C:\UE_5.2\Engine\Build\BatchFiles\RunUAT.bat BuildCookRun -project=SanctifiOrigin.uproject ..."

Running from the project directory gives the same error. How do I see what command the editor runs?

[winged moss]

it's probably the first thing it prints, but UFE might be easier to sus out

[hollow thunder]

Ohh, in the message log. I'll report back soon 💓

🙃🙃🙃 I gave it the wrong name of the .uproject file

It works now.

[winged moss]

It's always something stupid in the end

[fast ridge]

Hi! I have always packaging failed in UE5.1.1 when i use DLSS

Please Help!!!

[mystic atlas]

And the error is...?

[fast ridge]

it doesn't want to package, directly stoped

[hybrid hare]

after a successful package i get this message when opening project

how can i fix

[scarlet pagoda]

look in Project Settings -> Platforms -> Windows and see which shader formats you're targeting

there should be a section called Targeted RHIs

[hybrid hare]

Its set to direct x 11

I tried setting it to defaul & i tried with directx11 & both give me this message upon packaging

[scarlet pagoda]

have you tried DirectX 12?

[hybrid hare]

nope but i lose like 30-40 fps with direct x 12 on

my map sits at around 60-70 fps with direct x 11, then if i turn on 12 my map is like 20 fps..

So i stayed with 11 cause of the terrible performance i get with direct x 12

[scarlet pagoda]

give it a shot, just to see if it solves the launching issue

[hybrid hare]

alright

[winged moss]

that's still not enough information, there will be an error that's in the output log

"it doesn't work" is never enough information

[orchid ridge]

Any help for this issues?

[fiery terrace]

I wonder if anybody can help me with my issue. I've just upgraded the engine version to Unreal 5.2 with no issues everything works.
I've packaged the game for windows to test, and to my surprise, the first thing I see it's a black screen until the first map it's loaded. It takes at least 20 seconds and I feel like this is too much.
The first ever map I load it's very simple, just a widget with a image as a background. This image is 1mb in size but I don't think it's that much.
I don't have any hard references and anything strange, it's very basic.
Any ideas?
