packaging

[rocky dove]

Please explain how to enable World Partition streaming in Editor mode, i.e., without launching the game, so that chunk streaming works when flying the camera around the level.

[proven stone]

you... don't...

you use the World partition minimap to selectively load parts of your map

but there's no way to stream in and oud parts of world partition in edit mode

[cobalt pasture]

is the cooked content the same between platforms? i.e. when releasing on Steam, is it possible to have a depot with the .pak/.ucas/.utoc, and 2 depot for the Linux and Windows binaries?

[undone turret]

I believe so I have both platforms on separate depots steam will automatically detect the users depot and download the correct version of it afaik. The only differences should be settings where you make them platform specific (like I believe audio files can have platform specific compression)

But otherwise cooked content should be the same

[cobalt pasture]

i actually checked just now by copying the paks from a linux build to a windows one and it doesn't run :P

also, reading the documentation would've answered my question: "Converts assets into platform-specific content"

https://dev.epicgames.com/documentation/en-us/unreal-engine/building-multi-platform-games-in-unreal-engine

maybe if I used Vulkan on both it would work though

[undone turret]

Ah ok I thought you meant in terms of like what content was included but yeah the actual files will be different as they are compiled for that platform

I'm curious as to the use case of going between platforms? 🤔

[winged moss]

Cooking platforms separately is still way simpler

Or even easier, not having a native Linux port and just letting Proton handle it

[undone turret]

Yeah proton has improved a lot but I will say on steam decks at least a native port does help a bit with compatibility and performance with the dev cost being a few minutes to maybe an hour to setup the settings and then some extra time for packaging

[winged moss]

Supporting Linux isn't "a few minutes", it's a huge support burden

So it's easier to pass the burden to Valve

[proven stone]

There are certain ways you can share parts of cooked content, but trust me, not worth it... most things like materials, textures, meshes, sounds etc.. are usually in platform specific, especially on consoles etc...

and as sswires said, linux is a platform like any other, so the burden of maintaining that is the same as any other... i.e. it's a lot of work... testing... debugging etc.

[winged moss]

I worked on a rinky-dink Source engine game and supporting Linux there was such a drag, but this was pre-Steam Deck

The variables are so much greater with Linux

I think in the end hours spent providing player support outweighed the cost of porting and the income generated from a native port

[proven stone]

also compared to the number of people on windows, linux has miniscule userbase

and most of the users can easily use proton anyways

[winged moss]

We used the CSGO branch of Source and iirc the Linux version didn't even support rendering CSMs because the DX9 translation layer couldn't handle SM3 shader transpilation

So it was a compromised port but this is before we had the luxury of Proton

[undone turret]

Really? Maybe it's easier now I don't do anything to support Linux except package a build for it and it seems to work pretty great (at least on my dual boot PC and my brother's steam deck)

At least for Unreal Engine I'm sure there's definitely a lot of heavy lifting it's doing

[proven stone]

the build process itself is quite straightforward (I'll be assuming you're using C++ as that's what most projects end up using at the end of the day and not just BPs):

• install cross-compile toolchain
• try and compile for linux
• fix any code related issues that will creep up since for linux clang is used instead of msvc
• copy binaries to linux
• run it

or alternatively directly on linux:

• install native toolchain
• try and compile
• fix
• run

that's the easy part, then comes all the debugging, fixing and whatnot that comes up as a result of supporting another platform... and especially at the start there's high chance of stuff being broken unless the project just started

and there will be broken things not only on C++ side, but there's also a chance materials will start complaining because VK compared to DX has different requirements and whatnot, so some materials might fail to translate etc. etc.

[cobalt pasture]

tbh I didn't really have any issues supporting Linux

some stuff did break on the C++ side because clang is more compliant and picky on some errors

but I like that

the option to use proton is there anyways in the case where something doesn't work

but the Steam Deck build runs better with the native linux version in our case IIRC

I wish that Epic switched to clang everywhere, I feel like it'd be less hassle for them in the long run

[proven stone]

technically speaking you can use clang on windows... but you can't control console vendors so you'll be limited to whatever they choose

(although iirc Sony and Nintendo are using - modified - versions o Clang anyways... it's just microsoft using MSVC)

[cobalt pasture]

yeah, the docs aren't super great about it though, and because of that, I assume it's asking for trouble

[proven stone]

I wouldn't say asking for trouble, it's just not really used by epic so it's just there

although with advent of AutoRTFM which is clang-based a lot of things got fixed

so you should be able to compile with clang just fine

[cobalt pasture]

semi-related to this, what's libcef used for? I don't use the web browser widget, can I just delete it in some way?

it's absolutely huge on Linux compared to Windows

also also, these files seem to be duplicated and I don't know why

I also noticed that some games straight up don't have boost (e.g. Satisfactory)

[proven stone]

libcef is used as you've said yourself for embedding webview directly into the game... I'm not sure what preconditions are there for libcef to be copied or or... and same for the boost... you could try if it runs without, if it doesn't you can't remove them, if it does, you can remove them I guess

[vital terrace]

guys I've been packaging a dev build for like 3 hours

is it even progressing?

[proven stone]

well, seems like it's waiting for more ram to be available, so probably not

[chrome cloud]

Hello, how would one approach chunking in a world partition map?

Let’s say i want to make a game that has some part of it on chunk0 and then other stuff on chunk1 that the player can download later with chunk manager, or choose to not download (like another game mode)

Wouldn’t putting the world partition level into chunk0 automatically load every secondary asset in the level in chunk0 as well?

I use data layers in my map was wondering if there was a way to separate stuff into different chunks but i am having an hard time doing that

[proven stone]

You could make the plugin a game feature and store the external data layer in there… unreal will not load the datalayer unless the game feature is present and loaded…

(I’m not 100% sure if it has to be a game feature as it has been about a year since I toyed with this specific thing, but unlike regular plugins game features allow runtime loading and unloading, so they might work better)

[sleek stone]

Hello everyone, not sure if this is the right channel, but I am having some strange crashes for my game after a few seconds or minutes of using it.

The error is just a Fatal Error message without any other info. and it doesn't happen on all computers, just some systems are having issues.

Do you have any advice on how to find what is causing the issue or what can i do ?

of course is the clients systems that is having issues, the app runs fine on mine. :/

[summer dock]

Get the log files. There should be a stack trace in there.
If the log files don't say anything clear, add more logs to at least pinpoint the exact area where it conks out

[proven stone]

As karma has said, check the logs (or Saved/Crashes folder) - and I'd also recommend to enable packaging of the "Crash Reporter" with the game since that will give you better error window

[sleek stone]

Thanks both of you, I will investigate on how to do that. if you know a good source on how to configure things to get log files, Ill appreciate a lot if you share that.

could this be related?

[proven stone]

it could indeed, even though it's "just" an ensure it can still cause a crash

but... is it at the end of the log file or somewhere in between

if it's somewhere in the middle of the log it's not what caused the crash

[sleek stone]

that's the final lines of the file. but not sure what it means.

[proven stone]

well, seems like the GPU might've ran out of memory or some race condition... as SBT is generally a Shader Binding Table and the variable should not really be null

[sleek stone]

that's cryptic as hell for me... but thanks. I will try to investigate further.

[proven stone]

well, there's not much I can do to make it less cryptic since the crash is deep within unreal's bowels... and without having the project in front of me and being able to debug I can't tell you "oh, it's an engine bug" or "oh, it's this asset causing issues" etc.

[sleek stone]

yes I understand, I was hopping this would be something more common and straight forward to fix. but I will investigate, thank you for the help.

[bright kelp]

Hey, in 5.5 do console commands not work at all in packaged games anymore?
Even in Development or DebugGame packaged modes, I can't get the node "Execute Console Comman" to fire at all. I'm trying to take a screenshot for a save-game thumbnail

[bright kelp]

I guess my question is, is there a way to package the project in Unreal 5.5 and STILL allow the console?

[mystic atlas]

Isn't there a compile flag you can set to enable it?

[bright kelp]

I figured it out

[mystic atlas]

Damn, I thought the commands still worked even if the console itself wasn't enabled.

[bright kelp]

Even though the "Build configuration" was set to "development" there's a checkbox "for distribution". If that's checked, console commands are disabled (including blueprint events!)

There's a bug in 5.2/5.3 where console commands are STILL available in distribution builds. That's what caught me up as I just upgraded and my screenshot system no longer worked

[summer dock]

Hmm. We have an exec bp node working in shipping...

I guess it might be plausible that some commands might be restricted on shipping builds

[proven stone]

Certain cvars can be limited to editor only or non-shipping builds (they’re physically excluded from such builds) or they can be marked using CVAF_Cheat iirc at which point their execution is blocked in game itself iirc.

[proven stone]

Correction it's ECVF_Cheat... but the description still stands:

/**
     * Console variables marked with this flag behave differently in a final release build.
     * Then they are are hidden in the console and cannot be changed by the user.
     */

and calling "Execute console command" is the "User" changing it iirc, since it pretty much just simulates typing into the console

[summer dock]

so technically with a source fork one could remove the cheat flags ( maybe also having to move chunks of code from behind ifdefs... pain is fun )

[proven stone]

or, in C++ you could call the IConsoleManager and say you're something else like scalability etc. which should bypass that kind of checks iirc

// Set the screen percentage by evoking console commands
        IConsoleManager::Get().FindConsoleVariable(TEXT("r.ScreenPercentage"))->Set(OptimalScreenPercentage, ECVF_SetByGameSetting);

this is what we do when using DLSS, it allows us to easily unset that specific level when we disable DLSS which makes it work well with default scalability etc.

[keen moss]

Hey folks. Getting these errors that I think might be causing my packaging to fail. I'm reading some forum posts that say I have to fall back to Steam SDK 1.53 because this message is telling me that my version is too new. Does that seem accurate?

UATHelper: Packaging (Windows): Module.SteamShared.cpp.obj : error LNK2019: unresolved external symbol __imp_SteamInternal_GameServer_Init referenced in function "public: __cdecl FSteamServerInstanceHandler::FSteamServerInstanceHandler(class FSteamSharedModule *)" (??0FSteamServerInstanceHandler@@QEAA@PEAVFSteamSharedModule@@@Z)```

[winged moss]

unless you have a native project source build, do not attempt to upgrade the Steamworks SDK from the default

[fallow oar]

does the Untracked meta property work to exclude certain Properties from a cook?

[keen moss]

Well, shoot. I already did. So... In order to fix that, should I figure out what the default is supposed to be and replace it or... Can I delete it completely and then maybe there's a way to "verify files" or something, to get Unreal to reinstall the default?

[winged moss]

you can verify files in the epic launcher

[keen moss]

Ok. So in this case, would you recommend closing the project, deleting the SDK folder from engine > source > etc etc

Then verifying files from the launcher? And when I do that, I assume I'll have to re-enable the plugin in my printer but my config info and build.cs should be good to go

[winged moss]

verifying will restore Steamworks.Build.cs as well as the missing files from the previous SDK

[keen moss]

Thanks

[keen moss]

So I'm deleting the whole steamworks dir not just the SDK folder

[ember ether]

Hello! I'm having issues with my packaged game that are not happening in editor. Mainly 2:

• the first one is a random crash that happens where the image shows. Most likely GC deletes the actor for some reason. Because the crashing function is execIsValid. However, my issue is that when packaging, the pdb file successfully links to project source files, but not to engine files. How can I fix this to properly debug the issue?
• Second issue is with visuals. And I have no clue why. I have a bunch hierarchical instanced static mesh component spawn a bunch of instances on level load, however, some of these components are invisible until I add or remove an instance from them later on. This only happens in a packaged game for some reason.

[ember ether]

Seems like the two issues are related somehow. After some testing, I concluded that the crash occurs when the hit component is one affected by this invisibility bug. It is also odd because it is only LOD0 that is invisible. So the meshes will be visible from afar, but not when near.

[keen moss]

Thanks. Got it all fixed up and packaged.

[keen moss]

Hey again all. So my project folders and .uproject file are using a working title, so when I package of course, it packages the .exe file as the working title. Is there a way to change this so that I don't have to migrate the whole project to a new project or try to manually rename things and redirect folder references? I'd just like to ensure that the customer facing files reflect the actual title of the game and not the working title.

[winged moss]

the name of the target determines the executable filename

the Target.cs doesn't necessarily have to match the project name

the name of the uproject determines the subdirectory the game goes into

[plain adder]

Hi all, I'm on Unreal 5.5 and have just added the Nvidia DLSS/DLAA plugins and their dependencies to the project. Prior to adding these plugins the project packaged successfully. The plugins have been moved to the Project Plugins folder (not the engine plugins) and work correctly in editor.

One of the dependencies is the StreamlineCore plugin, which throws errors during packaging. It throws the same error in about 20 different header files throughout the plugin.

An example of one of the errors:

..\ProjectName\Plugins\StreamlineCore\Source\StreamlineCore\Public\StreamlineDeepDVC.h(20): error C7742: 'Streamline::EStreamlineFeatureSupport': a forward declaration of an enum can only use a simple identifier

An image of the header file where this error occured is attached below.

Any help would be appreciated, thanks!

[keen moss]

So I just need to modify Target.cs and I'll have the executable named correctly. Thanks m8

[keen moss]

One more question for y'all: I always get an unknown build error when I'm packaging which I can fix every time by deleting my binaries and intermediate folders. Anyone else have that consistently happen and does anyone know why?

[summer dock]

sounds sus - shouldn't be like that

I am forced to delete Binaries + Intermediate relatively rarely, usually due to sizeable c++ changes

[keen moss]

Yeah I thought it was weird. I need a packaging consultant lol

[summer dock]

Scrutinize the logs. One angle could be to take a working log and a failing log, and running a diff on them with WinMerge or similar

Gather information :

• does it happen intermittently ( unpredictably? )
• does it happen every time you change a certain area?
• etc
  to try to narrow down suspects

Verifying engine is always an option, sometimes a cosmic ray flips a bit somewhere : P

[keen moss]

I actually just did that but I'll do a log comparison. That's a great idea

Guess I'll toss the logs into Claude and run a comparison

[flint tree]

Hello, Is it not possible to package a lyra game, using Unreal Egnine from the launcher?
It packages, but the exe literally does nothing

[serene quartz]

Hi I have a question, what would be the most important things that are preventing me from packaging my project successfully?

Which error should take priority ? I dont have a lot of experience with debugging packaging errors, im only starting out in it, but this log seems too big for any human to be able to understand anything, if these are all errors then it seems impossible to understand what's wrong

and there's barely any tutorials out there on youtube on how to tackle, interpret or understand these things

[proven stone]

Seems like you ran out of memory while cooking

At least at first glance - hard to read this as I’m on phone right now

[serene quartz]

true, and my character also looks corrupted or broken, chatgpt told me

im not sure how to fix that tbh

[proven stone]

Ignore what ChatGPT says… in these cases it’s likely to be confused af

[proven stone]

For memory… downloadmoreram.com (get more ram) or expand your page file - use google for that… it might help

I’ll double check for some secondary errors when I’m back at the hotel (unless I forget )

[winged moss]

that was definitey OOM because they only have 8GB of physical system memory

that's not even a piss in the ocean in terms of what you actually need for doing gamedev work

especially memory intensive operations like cooking

[raw timber]

Hi ! I'm trying to build a game by command line but i'm getting this error

[bright kelp]

Pic on the left is in Engine, Pic on the right is Packaged. Any idea why there would be so much more pixelation on the packaged product?

[tulip turtle]

im trying to make a slight modification to an existing pak file thats compressed with oodle and uses AES key for extraction of assets and when i packed everything together with unrealpak im getting an error like this when launching the game

yes it exists

i can send the pak file if needed unless someone else has a theory

[slate hemlock]

A bunch of content is missing from cook errors appear when cooking/packaging the project

not a single one from listed that I opened has nevercook checked

I am gonna cook it again and will send the screenshots here

[winged moss]

even better would be the log, as text

[slate hemlock]

it's the section from this screenshot and until the very end of the log

not a single red pixel above it

nvm, opened it again, brb

here we go, the entire log

I am going to try turning off some plugins to see if that'll change anything, because whole log is way too long for someone to read through

[proven stone]

Seems like you’re referencing some editor only asset in one of your assets and that’s why its angry

[slate hemlock]

I am gonna look at it but I don't see in anything that I have used

I turned off water plugin because I decided not to use it for this project anymore, and it did cause some errors before turning off

gonna go around all levels, ctrl a and check if anything makes this display a dash, I wonder if it'll work like I intend it to

seems that nothing flags it as so, gotta go now into every asset that will set off the red text in the log after another attempt at cooking

[winged moss]

or you can do the thing that will remove guesswork:

Set Project Settings -> Engine -> Cooker -> Cooker Progress Display Mode to Instigators and Names (and Count) to get a log for when each package starts getting cooked, while also showing the Instigator, i.e. the reason why that asset is being included into the cook. Helps a lot when you get cook errors that don't show you which package they originate from.

[proven stone]

ok, your VRPawn is trying to load ton of things from "VREditor" module, but that's only an editor module... so that's your issue

[slate hemlock]

now I wonder how do I fix the issue, because that's the first time packaging anything in ue 5.5, before - I succesfully packaged a 5.4 vr demo, and it didn't have a single cooking error

[proven stone]

easiest way would be to stop using assets from VREditor module, either by replacing them with your own, or by selectively copying the assets to your game

and honestly I find it werid that this would cook in UE 5.4 this module has always been editor-only and editor-only modules have been "NeverCook" since forever ago

but if it works for you in 5.4 then one more way would be to go back to UE 5.4 since that would require least amount of work

[slate hemlock]

My demo in 5.4 had one level, not a single change was made to the VRPawn except locomotion changes(removed teleport and snap turn in favor of "gliding")
Right now - vrpawn is literally the same but has added assets not from VREditor module(couple static meshes and grab components)

i am going to try replacing whatever assets might cause the issue, because there is like a dozen of them in vrpawn

[proven stone]

from what you provided it seems to only complain about /Engine/VREditor/Devices/Generic/GenericHMD

[slate hemlock]

yeah I checked it again and I will make a copy elsewhere with a different name and change the reference in pawn itself to see if that's gonna make a difference

deleted the backup vrpawn, replaced the headset model with one of the meshes I have in the project to see if it'll cook

it cooked

lmao

[slate hemlock]

thanks for the help

[proven stone]

no worries, glad you got it working

[slate hemlock]

in the prototype I will show, player will now have an oil can for the head, lol

[slate hemlock]

any idea why it won't possess the pawn in packaged game? Playing through steamVR

in editor it works fine

It's set to be automatically possessed in every level, but menu level doesn't

UPD: figured out, jumped through some hoops to make it work but it works now

Make sure that you added it to the steamVR library, flagged as VR game and launch it directly from steamVR

[bronze nest]

Hi All, we develop a runtime plugin, used within our studio to implement some game features. We distribute to our artist a prebuilt version of the plugin, so they don't need to install Visual Studio.
Everything works during project development and preview in Editor.
But when it comes to packaging Unreal asks for Visual Studio even though:

1. the packaged plugins have all the intermediate precompiled versions, both for development and shipping,
2. every Build.cs file in the plugin has been modified to specify bUsePrecompiled = true;

Any hint on how to package a project with our plugin(s) without Visual Studio installed?

[winged moss]

This doesn't sound like a very common usecase, since you'll need at least VS to produce the final game executable

Why are artists regularly packaging? That sounds like you should have a proper CI setup

[bronze nest]

We'd like them to be able to quickly package and test some features in the "deployed" version of the application on their own. If the need stands, we'll have VS setup on their machines. Thanks

[summer dock]

I would still second setting up CI systems. You apparently already have a growing team, so nightly builds / builds triggered at will become very very valuable

[bronze nest]

Thanks. To provide you an example, they need to test some contents added to a large world which uses World Partition. When testing in Editor preview, they are always stuck do to the editor "preparing meshes" while new cells are loading. In the packaged version you just wait once, but then the application runs smooth.
Would a project cook help for the Editor Preview?

[proven stone]

Editor will always wait… unless you’re waiting for ddc which usually isn’t the case… if you want smooth sailing then cookig the project and running that will be what you want…. Although in general I’d recommend sticking with editor and surviving the preparing meshes etc

[bleak scroll]

I am getting this package error

Normally, when cook fails, there's an error somewhere in the middle of the log and I just solve that, but this time there's literally no such error, the first time an actual error appears in the log is at:

LogWindows: Error: begin: stack for UAT

[weary hatch]

Hey team! Does anyone know if the conditions for getting the bootstrap exe to build have changed in 5.5? To my knowledge we're hitting all of them (generate the prereqs exe, have the -prereqs flag in our buildcookrun and have it present in it's shipping configuration in the build graph xml) but aren't seeing it 😦

[proven stone]

You also need to build the bootstrapper executable

Or at least have it present in the binaries folder if you’re not using source build

If you’re using buildgraph then this is it… can’t help much more as I’m on phone rn

´´´
<Compile Target="BootstrapPackagedGame" Platform="$(EditorPlatform)" Configuration="Shipping" Arguments="$(GenericCompileArguments)"/>
´´´
actually can do this 🙂

[weary hatch]

This is what we've got in our BuildGraph xml
<Compile Target="BootstrapPackagedGame" Platform="$(TargetPlatform)" Configuration="Shipping" Tag="#BuildToolBinaries" Arguments="-Project=&quot;$(UProjectPath)&quot; $(AdditionalArguments)" AllowParallelExecutor="false" If="'$(IsUnrealEngineInstalled)' != 'true'" />

It's coming from Unreal Engine Tool, the whole thing can be viewed here: https://github.com/RedpointGames/uet/blob/main/UET/Redpoint.Uet.BuildPipeline/BuildGraph/BuildGraph_Project.xml

[proven stone]

Hmmm… interesting… because prerequisites for getting the exe is:

• built bootstrapper executable
• have the UE prereqs in Engine/Extras… whatever path I don’t remember from top of my head
• use the -prereqs flag

Confirmed working in ue 5.5 for us

[weary hatch]

We've got Lyra building with the bootstrap exe on 5.2 with the same build pipeline, I reckon it could be a "I've not configured some setting somewhere in the build stack" issue if it isn't a 5.5 issue, good to have the requirements confirmed though thanks for your help!

[karmic flume]

For those who already packaged (or cooked) successfully in 5.6, which Visual Studio version are you using? I'm on 17.8.6 and I don't know if this is the problem...

(I'm on Community version of Visual Studio)

[proven stone]

Check the release notes for 5.6 there are all versions for everything

[karmic flume]

Yeah, my version is compatible for 5.6, but still it doesn't cook or package. Although it compiles my c++ without problems

[karmic flume]

not even sure it's related to visual studio

[proven stone]

Cooking is probably not related to visual studio

[karmic flume]

weird that I can cook and package in other UE versions

[proven stone]

Ideally post the log and someone will take a look

I’m currently busy in a pub so I can’t take s look, but others for sure will

[karmic flume]

this is the part of the log after I press "Cook Content" in the Editor

it doesn't produce log errors. Then packaging fails because it didn't cook anything. This is a fresh Blank blueprint template from the Launcher btw

in my understanding, Visual Studio shouldn't be needed to cook or package blueprint projects, but still...

[karmic flume]

that's weird, this is what I see on the site:

I'll try 17.14... I was avoiding that because changing VS versions gave me problems in the past and I have active UE5.3 projects

[proven stone]

Yeah, there were certain versions of vs that broke UE because of a bug in that era… 5.4 and up is fine again

[winged moss]

The IDE version is rarely important, it's the toolchain and that remains unchanged from 14.38

You do need a compiler when you have a BP only project if you have something like non-default plugins

[karmic flume]

the only plugins enabled are the ones that already come enabled by default in the Blank launcher project

[ember marsh]

@plain adder I am currently experiencing the same issue as you. Have you managed to resolve it? In my case, it works on one computer but not on the other.

[plain adder]

Hi, yeah I managed to fix it. It was a blueprint-only project, so it was having trouble recompiling the plugins when packaging. I converted the project to a c++ project (by creating an empty placeholder c++ class), generated the visual studio solution, and then in visual studio, used Clean Solution and Rebuild Solution to do a clean recompile of the plugin files.

After that I ran the unreal project through visual studio, and packaged the project without issue.

[waxen aspen]

I've just upgraded my template from 5.4 to 5.6 and am receiving this error here on startup. Packaging and everything runs fine, there are no other warnings or errors. Setting cooker progress display mode to "instigaators and names and count" didn't give more info.

LogAutomationTest: Error: Condition failed

Logs also didn't give more info

and there is no crash to investigate

Tried upgrading the 5.5 version to 5.6 and it showed the same error

[winged moss]

Attach the log

[winged moss]

this looks like an average editor log with that randomly put in there. does it actually block any functionality?

I wouldn't recommend packaging from the editor UI to begin with

[waxen aspen]

No it does not do anything. Packaging, zipping, playing, everything runs perfectly fine without any warning or error. Just there is that error on startup I mentioned

[waxen aspen]

It's a blueprint only marketplace template so yea

All other UE versions didn't show this error

[karmic flume]

So I updated VS to latest version 17.14.4 and same error persists (no cooking in UE 5.6)... Plus now my UE 5.3 code doesn't compile anymore (as expected)... So I'll revert to VS 17.8.6 and continue to investigate why UE 5.6 isn't cooking on my PC

[tight mist]

Getting cook crash when worldpartition level is about to get cooked. No issues in editor but cooking fails. In unrealinsight BodySetupDDCFetch/DDC_GetSynchronous/DDC_Get Freezes

Anyone else with same issue or idea why it crashes like that. Using UE5.6. No issue in UE5.5

[tight mist]

Nevermind, got it working. Moved DCC and cooked everything again.

[winged moss]

I'm not sure why you ignored the part where IDE version literally doesn't matter

It's always the toolchain

5.3 uses 14.36, 5.4+ uses 14.38

[karmic flume]

because in the past I had BP-only projects that wouldn't package and the msg error complained about visual studio

plus in the past when I updated VS to be able to compile c++ in UE5.5, the UE5.3 stopped compiling and I had to spend significant amount of time trying till I found a version that compiled both 5.3 and 5.5

it's kind of a mess

[winged moss]

Well I'm not saying this as an opinion. UBT looks for specific toolchains that are installed and has a list of ones that are preferred

the IDE and toolchain are independent

what you have to install is the top pin on here because it's a common troubleshooting topic

[karmic flume]

not sure I understood

oh, pinned msgs, ok

[karmic flume]

Found out that if I use UnrealEditor.exe instead of UnrealEditor-Cmd.exe in the command line it does cook the content. The editor runs the command line with UnrealEditor-Cmd.exe, witch isn't working in my case.
So I suppose I can also package via command line using UnrealEditor.exe, but I guess that'll be whole new journey...

[lost flame]

Anyone seen some absurdities with a packaged 5.6 project ? Its basically empty, converted from 5.5 and has major bugs when loading maps..

Crashed my gpu 6 times in a row for instance

[summer dock]

Have you dont the full cleanup of Binaries+Intermediate+maybe DDC as well before packaging on new setup?

[lost flame]

No, ill give that a try, ty !

Was gonna test with a new 5.6 project and see if its just my project being weird

[summer dock]

sanity check is always a good idea yes

[winged moss]

You're supposed to use RunUAT BuildCookRun which launches UnrealEditor-Cmd, which is able to run the cook commandlet. If this doesn't work then there is something seriously wrong with your engine install.

[waxen aspen]

Doing it from VS also only showed that single error.

[winged moss]

You wouldn't package from VS, that just builds the executable

[waxen aspen]

I didn't mean packaging. I meant starting up in debug mode vom VS

Sorry, it was confusing because I responded to that message

However, I have just created a completely new UE 5.6 third person project and that has the same error.

I will verify the the engine version

[waxen aspen]

Didn't help

[karmic flume]

was removed and reinstalled about 2 or 3 times and verified about 2 times already... and the issue was present in the preview version too

[karmic flume]

lately though I've been suspicious of this SSD (for other reasons)

(in which the engine is installed)

but still seems weird to me that the issue would return always on the same part of the engine and that the verification would fail...

[karmic flume]

so today before I finish reading the RunUAT docs I tried again launching from the Editor (Platforms -> Project Launcher and Platforms -> Quick Launch) and it worked
then I packaged from the Editor and it worked. While yesterday it didn't even after I managed to cook via command line
still going to finish learning how to use RunUAT because I feel this issue will manifest again

[visual dawn]

OK so from searching in this Discord I can see that to add my own default graphics preset for players, I need to add a bunch of [ScalabilityGroups] to a file called DefaultGameUserSettings.ini in the Config folder of my UE5 project. Great!
I went ahead and did that, assuming that it means the project folder location, e.g. D:/MyProjectName/Config/filehere, and not in the packaged (shipping) project folder D:/PackagedBuilds/MyProjectName/Config/filehere - since that would be weird to have to add each time, right?
However, when I do it feels as if nothing happens in my shipping build, after deleting the %APPDATA%/Local/MyGameName folder to test.
What am I doing wrong?

[visual dawn]

I'm just testing it wrong. I was expecting it to put the setting into the GameUserSettings.ini file, but it didn't and had vanished the default (quality lv. 3) settings it was inserting itself. Turns our it just applied the defaults I'd set then doesn't update the GameUserSettings.ini - all good

[eager cedar]

If I use RunUAT.bat to generate an Android project, it does not create an obb file (and if I have packagedatainsideapk, the obb is not within the apk).
Anyone knows why? Does it not work?

[summer dock]

check your configs - packaging with runUAT is fine, packaging from editor just calls that as well.

[summer dock]

to create an apk ( and opposite for aab ):

bPackageDataInsideApk=True
bEnableBundle=False```

[quasi temple]

Hi! I know what soft and hard dependencies are from hard and soft references etc, but what is a “hard save dependency”? I’ve been seeing files cooking and the instigators have often been listed next to the cooked files in the log, in a lot of cases they are files in the ExternalActors folder which I understand where all the OFPA are stored for world partition. But I don’t understand when a file has an instigator that is a “hard save dependency “ as the package name generated can’t be found in the outliner of the map I’m cooking ….

[quasi temple]

*apologies - SaveTimeHardDependency not hard save dependency

[chrome cloud]

Hello, i'm having problem with asset referencing and chunking. Currently i have Chunk1 that contains stuff it shouldn't have.

For example in the screen you can see that BP_CorridorBricWall1 is inside chunk1 because it gets referenced by MainLagoon which gets referenced by MainLagoon2. Problem is that in MainLagoon2 there are no references to MainLagoon.

Also, the reference node says "Manager" under it, and not "Level" or "World" like i thought it would say. What is this "Manager" right there?

this is how i set up my asset manager in case it is relevant ( i guess it is )

And when i package my game, i explicitly select only MainLagoon2, not MainLagoon

[eager cedar]

I checked. This seems to happen with Jenkins only, but we got no difference in the arguments there or the config.

[summer dock]

Should make no difference whether in Jenkins or not.
If you wish, you can show

• the .ini file
• the packaging log

Or, you could diff the packaging logs. Are you sure you are not doing any pre-packaging modifications to the setup, or something?

[summer dock]

this graph would seem to indicate MainLagoon has a ref to MainLagoon2?

[chrome cloud]

Problem is they don't have any reference to each other

[summer dock]

Well, reference viewer seems to think otherwise... ( is that the Reference Viewer? )

[chrome cloud]

Yeah it's reference viewer

[summer dock]

Tried "Find in Blueprints" in the MainLagoon levelBP?

[chrome cloud]

but it's saying that the reference is of type "Manager" and not "World" or "Level" like in the screenshot
this is from reference viewer directly of MainLagoon2 level

[eager cedar]

Here is the Log

[chrome cloud]

yup

[summer dock]

Hmm hmm

[chrome cloud]

i guess it's something related to how i set up that thing in asset manager

[chrome cloud]

this

[summer dock]

And you are intending to package aab or apk?

[eager cedar]

apk

it does generate an apk

but the size is too small (missing like 200MB) compared to building without jenkins.

It seems to be that it misses the obb

[/Script/AndroidRuntimeSettings.AndroidRuntimeSettings]
bShowLaunchImage=False
MinSDKVersion=29
TargetSDKVersion=32
bBuildForES31=False
ExtraApplicationSettings=
bAllowIMU=True
SDKAPILevelOverride=
NDKAPILevelOverride=
bPackageDataInsideApk=True

[AndroidSDK.AndroidSDKSettings]
NDKPath=C:/Program Files/Android/NDK/android-ndk-r21e
NDKApiLevelOverride=29
SDKAPILevelOverride=29

Those are the android settings

[chrome cloud]

If i use the Asset Audit tool, and select "Add managed assets of Type" and select "Map" from this, i get EVERYTHING referenced by all the maps, so i guess it's that thing that is causing the problem

[summer dock]

nothing really jumps out at me. I would take log A ( working ) and log B ( failing ) and compare them with WinMerge or similar diff software to hunt down more clues

[eager cedar]

good idea, will try this

thank you

[flat lake]

Yo folks! I have problem with packaging project after migration to 5.6 from 5.5. I made dozens of builds on 5.5 (on this project) and didn't have any error, but after migration I can't do a single build. Before migration I cleaned up DDC, Saved etc Do you have any idea what is going on? I'm packaging from Editor - didn't have any issues with it ever.

[chrome cloud]

Ok i managed to fix this, i removed everything from the asset manager in project setting and added only the PrimaryAssetLabel to be scanned.

Now i have anothjer problem. I have a packed level actor that i explicitly selected in a PrimaryAssetLabel to be inside chunk3, but no matter what i do, it ends up in chunk0.

The screen is the reference viewer of said packed level actor, and it even says Chunk3, but in asset audit it says it's in chunk0

what even is the point of using primaryAssetLabel if the engine decides for itself where my asset are gonna be chunked?

[fresh field]

Hi anyone know this error:~
delaying 1 processes from spawning due to memory pressure unreal engine

[mystic atlas]

That's not an error, just a warning that you're running low on memory.

[summer dock]

sanity check with a blank / template project maybe

[flat lake]

Tried. Everything works perfectly. 🥲 Right now I just run Validate Assets option on the Content. Maybe smth broke after migration 😔 Btw with one attempt I was able to build the project (everything works inside) but after this I have not been able to reproduce that - always same error.

[summer dock]

if it's in cook, can try this #packaging message

[flat lake]

Oh, looks promising 🙇‍♂️ Thanks, Ill try that!

[raw timber]

Hi ! i'm packaging a server build and would like to exclude some client code so i put it in WITH_CLIENT_CODE but the packaging fail on the code in the macro, Any ideas what could be the issue ?
I also tried !UE_SERVER

[rain mist]

I am having the same error, are you using 5.6 ?? i can't figure out the issue, got all m blueprints to compile without errors

What was your issue with motion matching ? i think i am facing the same issue

[rain mist]

Funny thing i was able to build sometimes

and sometimes not without changing much or even nothing, almost random, readlly hard to define a trend

i don't have localization yet on my side

[karmic flume]

More info on my problem since it has returned and I had to investigate further:

• Packaging via RunUAT BuildCookRun also doesn't work (it calls the same UnrealEditor-Cmd.exe)
• The problem is in the UnrealEditor-Cmd.exe file, since it doesn't open even when executed directly from command prompt without arguments
• Specifically the problem is in the name, since renaming it to UnrealEditor.exe makes it work, while renaming the original UnrealEditor.exe to UnrealEditor-Cmd.exe makes it stop working
• My working solution is to rename UnrealEditor-Cmd.exe to UnrealEditor.exe (on another folder to prevent conflict) and use a symlink on the original folder that redirects whatever tries to run UnrealEditor-Cmd.exe to the renamed file on the new folder (does work)
• I'm curious because so far I've never heard of problems like this

[summer dock]

It sounds like you are on the wrong track here.

1. Verify engine
2. Sanity check, package a blank or template project

[royal ibex]

it's been so long lol

[winged moss]

If you need more verbose information in the log in order for you to work out which asset is causing packaging to fail (or why an asset is being included in the first place), do the following:

Set Project Settings -> Engine -> Cooker -> Cooker Progress Display Mode to Instigators and Names (and Count) to get a log for when each package starts getting cooked, while also showing the Instigator, i.e. the reason why that asset is being included into the cook. Helps a lot when you get cook errors that don't show you which package they originate from.
via the "Advanced Debugging in Unreal Engine" article

^ if a <@&213101288538374145> could be so kind to pin that

[winged moss]

thank you

[winged moss]

well you don't have engine symbols so it doesn't give much away about the problem

[flat lake]

It helped me so much! Using this option I could track broken asset. In my case it was connected with function inside blueprint function library. Function simply returns DA and it worked across all engine version, but in 5.6 smth is broken. Anyway, after deleting this helper function, packaging works! Thank you very much!

I have many of BPFLs inside the project, and only this one caused crashes - so for me it’s a random

Yeap, had the same scenario - 1 in 20 attempts were succesfull

[summer dock]

text is best : )

[golden patio]

Why does cross compiling windows to linux sometimes not manage to compile the WorldGridMaterial shaders even after I explicitly cook content? And it's an issue with cross compiliation because my go to solution has been to switch to linux and direct compile, meanwhile windows has no issue

[winged moss]

same callstack as the other one, so might be a bug. You wouldn't know for sure without actually attaching a debugger

packaging runs in an external process, UnrealEditor-Cmd.exe, so you'd start the cook and attach

actually packaging straight from the editor UI is a little bit wasteful

debug > attach to process

attach to the running UnrealEditor-Cmd.exe process after the cook has started

[vague hearth]

Running into this as well. I was able to get a bit further by doing the exact debugging process you guys are describing. Still a bit lost as to what this ObjectRef is because of my limited knowledge about the cookling process

I see. I'm luckily (or, perhaps, unluckily) not so close to prime time. However, I don't want for this to bite me in the ass later on. I already found a bug in MetaHumans sooner today, so I wouldn't be totally surprised if it were

It's certainly a pain to understand

The bug, I mean

[winged moss]

you actually need to inspect the callstack and see what the values are

so that might actually give an indication of what the problem is

also a word of advice: don't upgrade the engine near an important milestone

that problem was a reference to a data asset, so what is it in your case? also if your game wasn't playable without upgrading to 5.6 then maybe Next Fest was too soon of a deadline

with a new engine release, it's best to wait at least until the first hotfix

there are always problems for people with .0 releases

[vague hearth]

Do you advise then to create a bug report? I'm always cautious when creating them, I try to be sure it is a bug before doing so. However, this is as much of a certainty as I'll be able to get with this one I think

In my case, I jumped to 5.6.0 just to start checking the new stuff

[winged moss]

I wouldn't really recommend managing a reference to an asset through a BPFL in your case, but it does seem like a bug

[vague hearth]

BPFL stands for Blueprint Function Library right? If that's the case, then there is indeed a BPFL referencing this asset. It is sadly a third party utility I'm using. I've been trying to replicate it in C++ and get rid of it for the longest time, but it's hard for me to find the time to do it

[winged moss]

yes it does

[vague hearth]

Ok, thank you very much. With this extra bit of info, I may be able to file a report detailed enough

May I ask how did you know it was a BPFL?

[winged moss]

it might be best to see if you can replicate it in a minimal project that you can attach

[vague hearth]

I see. I'll try that

[winged moss]

and I think I confused you with someone who actually did have that problem from a BPFL, but if the common thread is it being a BPFL then it's likely a bug there

[vague hearth]

Oh, then it's a very happy coincidence indeed

[winged moss]

I think one thing I would be thinking about is the referenced object as well (in this case the data asset), like is it based on a BP class or a native one? is there a circular dependency going on? that sort of thing

[vague hearth]

I see. It is not directly inheriting from Primary Data Asset, in fact. It derives from a class that, in turn, derives from Primary Data Asset. I don't think I spotted any circular dependencies between those, but I will take another look

[winged moss]

is it specifically PDAs?

[vague hearth]

It's a bit of a mess, but to the best of my understanding, there's a PDA blueprint defined, and then from that one, a regular Data Asset was created

I've only done stuff like this in C++, so I may be misunderstanding something, but I believe that's the setup

Then, a BPFL comes into the picture, with a variable that's pointing towards that Data Asset

Does this make sense?

[gritty helm]

simply mentioning (cast node, call, delegate node, variable declaration) can create a hard reference between bp assets,
BPFL is just an asset with static functions that is globally accessible, and using any functions from it creates said hard reference. most of circular dependency problems with access happen with them

[vague hearth]

The Data Asset that's causing trouble has a reference to another data asset. Could this be causing a circular dependency between PDAs? I don't think it should, but I'm not sure

[karmic flume]

Yeah, it's super weird, but I've tested many times with fresh blank and template projects, I've reinstalled and verified the engine also multiple times and on different SSD's. The problem also occurred in the 5.6 preview. Doesn't happen in older Unreal versions.
In older Unreal versions, double clicking UnrealEngine.exe (Epic Games\UE_5.6\Engine\Binaries\Win64) opens the engine while double clicking UnrealEngine-Cmd.exe opens the engine plus the Command Prompt window.
In 5.6, double clicking UnrealEngine-Cmd.exe doesn't open the engine and only opens the Command Prompt for a few seconds and then closes it. Sometimes there's a crash report:

[summer dock]

Sounds like 5.6 is buggy, maybe post https://www.unrealengine.com/en-US/support/report-a-bug

[karmic flume]

Could anyone confirm on their system that, on 5.6, clicking on UnrealEditor-Cmd.exe (Epic Games\UE_5.6\Engine\Binaries\Win64) successfully opens the engine plus a Command Prompt window?

[winged moss]

and since there are no symbols, that stack trace is basically useless

UnrealEngine-Cmd is only supposed to be for running commandlets, including cooking

[karmic flume]

yeah, that's how it's supposed to be used in my understanding, but when run without the command line arguments it opens the engine, except in 5.6

where it crashes

it crashes with or without arguments

[winged moss]

then you would need to get it to crash with symbols so there's more information than "it happened in the Core module"

[summer dock]

Options -> Editor symbols for debugging

[karmic flume]

I'll add the symbols

[karmic flume]

Crash report with the symbols:

[summer dock]

So this is something you could send off to epic bugreporting system I reckon, along with precise descriptions of your system, how reproducible the problem is, how it happens etc etc as much info as possible

[karmic flume]

Yeah, I'll do that. It's just weird that no one else on the internet apparently is having this issue

[normal rune]

Hey there!
I'm having this terrible assertion failed error when packaging

LogWindows: Error: appError called: Assertion failed: !IsRunningCookCommandlet() [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Engine\Private\Animation\AnimSequence.cpp] [Line: 4976]

I'm running a clean install of UE5.6

Project was packaging well before 5.6, when I was under 5.5

[summer dock]

Start by installing debug symbols.
Looks like 5.6 is a bit wonky...

I hope everybody has version control and are just testing the water, not committing : E

[normal rune]

Yeaaaaah totally committing here

Do you know what symbols exaclty?

Ah nice thx

I was looking into visual studio installer

Never used symbols before, is it just gonna add more infos to the error log?

[winged moss]

This looks very odd, like something an AV or malware is interfering with. You might be able to see more if you launch UnrealEditor-Cmd with -waitfordebugger and attach in VS

and I suspected that just because this function is parsing headers from a loaded DLL file

[winged moss]

did you clean your project DDC when you upgraded?

[normal rune]

Yeah I cleaned everything

Saved, Binaries, DDC, Build

Using symbols, the error list is a little big more precise

Still unclear tho

[karmic flume]

Thanks, I didn't know of -waitfordebugger. I was trying before to attach the debugger in VS but UnrealEditor-Cmd always crashed so fast before I could attach it

[normal rune]

I could fix the animation sequence assertion failed error by clicking Tools > Validate Datas

I randomly clicked that button and it somehow worked

It's like, pure luck?

[west granite]

Hi there. I am having a very similar problem trying to run 5.6 here. Instantly crashes on startup with this error. Did you have any luck fixing it?

[karmic flume]

Yes but my error is only when running UnrealEditor-Cmd.exe, if you're getting this when just opening the Editor (UnrealEditor.exe), then my workaround might not work for you... (it's not a fix, it's just a workaround):

#packaging message

(my problem only happens when packaging/cooking)

[west granite]

Oh, I see. Mine seems to happen immediately upon starting up the editor. No clue as to what could be the cause.

[karmic flume]

the log is very similar though

if you add the symbols to your installation, we would be able to confirm if this is the same error:

#packaging message

symbols take up a lot of space in your SSD though

[dry knoll]

Anybody used the new project launcher tool to package ? it has no localization options anymore and my packaged game no longer shows the different cultures (good setup in editor and project settings)

I'm recompiling the text in the loc dashboard right now and trying again, but appreciate it if someone knows about this

5.6 new project launcher UI

[dry knoll]

Yeah can confirm I can't get my culture choices to show up in packaged using project launcher
trying with regular packaging tool

ok i have languages now with regular packaging, maybe some things are missing in project launcher ?

[winged moss]

well compare the args it passes to BuildCookRun

but honestly I don't even remember there being an explicit localisaton step since you typically build the locres files ahead of time

[golden patio]

it's a menu when cook is set to by the book, frankly a long list of the localization options with no search...

Speaking of this new project launcher UI, does it fix the issue where cross compiling linux on windows doesn't compile default shaders?

[lyric orchid]

anyone facing this issue on 5.5 ? what is it on editor Graphich settings working perfeclty low high etc but when package its not working applying on 5.4 when ticking this working but on 5.5 crashing on startup when tick it project launcher package

Project Launcher Patching Issue - UE 5.3.2
I'm encountering patching problem with the Project Launcher.

Previously, I was able to manage game updates through the Project Launcher by creating a "base build". This base build contained all the necessary .exe files and so on. My project utilizes chunk/.pak files, which divide the content into many separate parts. With the base build, I had about 40 such .pak files (e.g., pakchunk101-Windows.pak).

When I created a patch/update using the Project Launcher, the original .pak files from the base build remained exactly the same. The update process would generate 40 new .pak files containing all the updated material. These new .pak files were significantly smaller in size and had names like pakchunk101-Windows_0_P.pak. The _0_P.pak suffix was the distinguishing factor.

However, during a reinstallation of the engine, I lost all my Project Launcher settings. Now, I can't get the patch creation to work in a way that generates updates into those _0_P.pak files.

Currently, when I create a patch, the Project Launcher generates _0_P.pak suffixed files in place of the original ones, and they are just as large as the original .pak files. I don't want this behavior.

So, what do I need to do to ensure that patches work in a way where the original .pak files (like pakchunk101-Windows.pak) remain untouched, and the launcher only creates new, small update files (like pakchunk101-Windows_0_P.pak)?

[final scroll]

hello! i would like to package a demo of my game using different maps. I would like to be able to override MapsToCook in DefaultGame.ini according to my target.
Currently I am going the "CustomGame.ini" route. I created:

Config/Custom/Demo/DemoGame.ini with a simple IsDemo=1 entry and Im trying to target this using a MyProjectDemoTarget.Target.cs file (which inherits from the base MyProjectTarget).
In there I set:

CustomConfig = "Demo";

All is nice and dandy. But, CustomConfig requires a Unique build environment. Which requires a source compiled version of the engine.
Am i overcomplicating? Is there a better way?

[summer dock]

What we do is manipulate the .ini files with a python script to get various build flavors ( and run the runuat.bat as well )

[final scroll]

ha indeed didnt think of that. open ini, locate&update value, build. as much as i would like to have a separate file it seems there is no workaround that would not require building the engine from source. thanks for sharing!

[west granite]

A quick update, I 'solved' my problem after reinstalling the latest C++ package here. It looks like the Launcher tried to install that automatically but it didn't go through as expected, so the manual installation seems to have solved the issue. At least the crash upon startup issue. https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

[karmic flume]

Thank you for this! I'm not sure I'm going to try this now because messing with MSVC might make my 5.3 projects stop compiling C++, as it happened when 5.5 came out and I updated Visual Studio. But when I migrate my projects to 5.6 I'm definitely going to try this, thanks again!

[final scroll]

So just for the records: I went on and compiled unreal from source and setup CustomConfig. Which works. But, it seems, MapsToCook cannot be overridden by the DefaultGame.ini file.

The only viable way I found to package custom maps is to pass them as arguments to RunUAT.

This is...confusing

[summer dock]

or, you mean can't CustomConfig can't override the engine.ini... huh
That seems unfortunate

We have python scripts to modify DefaultEngine.ini etc as needed

+MapsToCook=(FilePath="/Game/Maps/StartingLevel")```

[winged moss]

there's all sorts you can do. You can pass custom args to the cooker args through -AdditionalCookerOptions

so you can combine that with -customconfig (a runtime version that works in the editor) or -ini

there is also the concept of map lists

[final scroll]

Customconfig works to add new categories. So if i add this to the custom DefaultGame.ini:

[NewCategory]
Foo=Bar

Then I can read Foo in game. Tested, working.

But if i add

[Script/UnrealEd.ProjectPackagingSettings]
!MapsToCook=ClearArray
+MapsToCook=(FilePath="/PathTo/MyMap")

Then MyMap is not cooked

[final scroll]

Oh ok I am not aware of this or the other concepts you mentioned. Would any of these allow the cooker to actually override MapsToCook following the custom config?

[winged moss]

-AdditionalCookerOptions=" -CustomConfig=Demo" should work when I was looking through stuff last night

Otherwise -Maps= followed by a plus sign delimited list of maps should also work

[final scroll]

I used "-map" and it works, didnt see Maps. i will try the AdditionalCookerOptions because somehow having a list of maps declared in a file...i find it clearer somehow

thanks!

[dull phoenix]

In ue5.6, where are the options in project launcher such as "don't include editor content" or "include an installer".

[royal wolf]

Trying to package my project but I keep getting an error. "PackagingResults: Error: Unknown Error" no warnings come up

[dull phoenix]

I am trying to package my project in UE5.6 using ProjectLauncher. It took more than 4 hours to finish. Why is that? Anyone has a working settings?

[summer dock]

post the complete log file as .txt

[summer dock]

If you have a lot of assets, the first cook can take a long time?

[winged moss]

two vague questions

[royal ibex]

if my package or cooking just fails without any error what should I try next?

there are errors "... is not initialized" but I have completed build earlier with these errors still existing so I am pretty sure these aren't the reason behing failure

[royal wolf]

I did that wrong holdup

Its a txt file

Ive tried multiple times but it always has an error right as it finishes

[summer dock]

The log is a bit weird, heaps of repeating errors. Assuming you are packaging from editor, please do like this

• clean start unreal
• package
• copy log file
  OR
• clean start unreal
• Clear output log window
• package
• copy output log contents to .txt file

[royal wolf]

Might be a few hours, took me 4 hours last time

[summer dock]

So that log is from pressing package once? You have something weird going on, there's a LOT of errors

[royal wolf]

I’ve tried packaging 3 times

[summer dock]

I would suggest you start by sanity checking that you can package a blank/template project...

[royal wolf]

Alrigjt thank you lmao

So that log looked like it had 4 times runuat mentioned. That just makes things very confusing. A clean log has just one pass.

Playfab plugin looked like it was causing a majority of errors, so disabling that might be a good move

[royal wolf]

Alright thank you

[weary flare]

I am trying to track down why my packaging is failing. I'd like to get a more specific error than:

LogWindows: Error: appError called: Assertion failed: Linker [File:D:\build\++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 2152]

Which is what the log.txt shows

Something with UObjectGlobals.

[summer dock]

• Try the tip in the first pinned post

[royal wolf]

How can you see that

[summer dock]

up top

[weary flare]

Givin it a go thanks.

[royal wolf]

I was saying how do you know its playfab causing the issue

[summer dock]

not sure, but there's a lot of lines like this
LogPlayFabGSDK: Error: GSDK ServerActive Delegate is already bound! Will unbind the old binding!

My basic technique of looking at a log:

• open the file in a proper text editor like Notepad++ or similar
• search for all occurences of "error"

Your log has 605 hits, which is about 600 too many

so you need to start doing things to lessen that number. Look at the logs with "error" and try to get rid of them

[royal wolf]

ok thank you

[weary flare]

Alright looking at the error log but I'm not entirely sure still... The last thing I hit before an error popped looks like:

LogCook: Display: Cooking /Engine/EngineMaterials/Widget3DPassThrough_Masked_OneSided, Instigator: { StartupPackage }
LogCook: Display: Cooking /Engine/EngineMaterials/Widget3DPassThrough_Masked_OneSided
LogCook: Display: Cooking /Engine/EngineMaterials/Widget3DPassThrough_Opaque_OneSided, Instigator: { StartupPackage }
LogCook: Display: Cooking /Engine/EngineMaterials/Widget3DPassThrough_Opaque_OneSided
LogOutputDevice: Warning:

So if I had to guess its in the Widget3DPass?

right after that is when I hit the 2152

[summer dock]

So yeah, try isolating that bit ( I mean temporarily removing it, if things then work, you know that's the problem for sure )

[weary flare]

Any advice on uh removing widgets or HUD so I can cook without deleting it? I'm not exactly sure what to do.

[summer dock]

Do you use version control?

[weary flare]

Unfortunately not for this, this was just me learning things and it spiraled from there... Going forward after having multiple blueprint corruptions. Yeah always going to

[summer dock]

Well, consider starting that asap. Meanwhile, can just take a brutal backup of the whole project folder ( though you don't need Binaries and Intermediate ), then proceed nuking stuff

With version control, you could do things with impunity and restore your state at the press of a button : )

[weary flare]

Sounds like a plan and yeah I just copied everything before troubleshooting

[fading chasm]

Im having an issue where playing a packaged game will cause crashes because something removes or unloads assets that UE deems unused at the time.

For example, I have some empty actor classes throughout the level and despite being referenced by world settings, packaged build will come back with NULL.

Is there any way to force a specific asset and actors to not be... "optimised" out?

[weary flare]

Yeah its lookin like its a widget blueprint is the issue in my copy i deleted the widgets and its cooking fine. So now i just have to process of elimination

[weary flare]

Thank you again for your help with the advanced info. Was EXACTLY what I Needed We got the bugger

[mystic atlas]

There are "always package" directories you can specify in the packaging settings.

[dull phoenix]

are you suppose to choose zen streaming or legacy for cooking

[royal wolf]

Unknown Error when trying to package, anyone know why?

Espcially with this part and the makefile

[winged moss]

whatever plugin has the module "VolingaRenderer", you're likely missing it

[short temple]

hmm thanks a lot ! i'll try reinstalling it then
even though i was able to activate it in engine

[winged moss]

that doesn't tell me very much, is this a Fab plugin?

[short temple]

it's this plugin 🙂 https://web.volinga.ai/
For gaussian splats

[winged moss]

yeah I'm not really interested in that. I'm more interested in where did you acquire the plugin, if not Fab, where is it installed?

[short temple]

oh i see sry
It's installed in my plugins folder in the 5.5 folder

[winged moss]

external plugins installed to a binary engine aren't going to work quite right

[short temple]

ah ok i see.. how could i do it properly then

[winged moss]

if your project is a C++ project, which is easy to convert if it's not, just install it to the project's Plugins directory

the only alternative is packaging the plugin which seems pretty jank and is usually for Fab distribution

[short temple]

Isn't what's iv'e done ? installing it in the projects directory ?

sry

[winged moss]

your project's Plugins directory is not going to be in the engine directory

[short temple]

oh ok !

because in the tutorial they said to install it there

[winged moss]

well the tutorial is wrong

[short temple]

so i'll make a c++ project and a new plugin folder in the projexxt

nhere i guess

i'm having new type of issues 🙂

[dull phoenix]

Any idea why I cant save my packaged project

[fading chasm]

This empty actor isn't something I've made though. It's UE's default implementation of whatever actor is.

[mystic atlas]

Errrr

If it's just AActor... That's always available.

[fading chasm]

which is really strange

because it returns nullptr

I added billboard component to it

and it works fine now

like as if packaging the game optimised out the empty actor

[weary junco]

Whenever I try to package my game it always stuck on some m_groom_binding from one of the metahuman grooms, whatever I do and how much I wait is doesn't matter it always stuck at it, if it's at 163 packages left it stucks at 163 packages left for 20 hours, can anyone help?

[pastel pasture]

is there a way to package my game with the lowest settings possible?
Usually when I package it and try to run, it gives the highest options for those scalability groups, do you know how to make them all be low?

[pastel pasture]

try maybe deliting it from the project?

or do you need it?

[weary junco]

without that my metahumans would be all bald xD

[pastel pasture]

😦

[weary junco]

idk if you can package it with low settings but

in start menu that you choose in that level, put low quality settings and save settings to begin play

your project would be start with low settings and that setting would be saved

[pastel pasture]

trying this right now to see if it works 🙂

on level blueprint

[weary junco]

this ue5 problems is really annoying like i'm trying to package my project for a week, but no solution that i find is useful

let me show you how to do it

wait

there should be unreal engine support to solve these problem, like it's metahuman groom, it's not custom groom yet i'm facing a problem that stucks forever

[pastel pasture]

I remember I used to have lots of errors with it, I had to switch my pc in order to make unreal run better, I used to have to delete entire unreal engine version and install it back for the packaging to be succsefull

[weary junco]

that's what probably i'm gonna do

i deleted derived data cache, cooked folder, everything but none of them helped

[pastel pasture]

yeah you could see if that works until you find a reason for it

[weary junco]

this is how you do it, 3 is epic setting, 2 high 1 normal 0 low probably

this is on my main menu, i put it in to beginplay

[pastel pasture]

oh thank you buddy!

[weary junco]

i hope it helps

[pastel pasture]

but I guess I can put it directly on the map level blueprint, no?

[weary junco]

u will want to put this on main menu, (project start menu) because it's better no?

ye level blueprint

my bad

[pastel pasture]

yeah I will see what I can do with it

[weary junco]

i already tested it multiple times that's how you do it, you can open a settings UI and put this also

[pastel pasture]

Yeah I will try it out, thank you!

[weary junco]

yeah no worries, you can add me and ask questions if you needed, unlike my problem my comment will be ignored and no one knows the solution probably, we should contact ue5 devs itself to solve this but nah there is not support link to contact them unlike steam support or something

[pastel pasture]

yeah you should ask it again and leave it, so people will notice it 😦

[fading chasm]

meta human groom is extremely performance heavy, if your goal is a low end machine, you need to not use it

you can convert them to cards which is way more optimised for real time games

[dull phoenix]

in ue5.6 using project launcher, why it won't save the shipping packaged build project. I checked archive build and added a folder location. Any idea whats wrong

[hexed hearth]

Anybody has a clue why packaged groom starts working with a 10 second delay? It's floating above the head of my character... until it snaps to the head 10 secs later but only if packaged. In character preview, or in editor it snaps instant. I can ofc hide the character in packaged games for 10 secs with some loading-progress bar or whatever but I have no idea what. I would not just guess a random value. It's even a bit annoying that it's working in non packaged versions as this makes trial and error pretty time consuming.

[weary junco]

ye i know that thank you for info but main point of my game is only dialogue with good looking characters, there is no combat or something, only story and dialogue within levels with multiple endings

[weary junco]

do you mean when you open your packaged game characters groom hair loading a while later? do you know marvel rivals or the first descendant? they force you to compile shaders when you open the game first time, while it compile shades it loads grooms maps materials etc, without that when you open your packaged project for the first time your characters will be bald or nude due to compiling problem but once it loads it will not happen again

[chrome cloud]

Hello, i have a PrimaryAssetLabel that references a map, in this case Untitled3.
In the reference viewer i can see that Untitled3 has a reference to BP_Arduino, problem is that in the map there is NOTHING referencing that BP, not in the outliner, not in the level blueprint, yet i still have this reference to the BP and thus loading every dependency and messing up my chunking setup

This happens for other assets aswell, with hard and soft references.

The actors in Untitled3 (that have nothing to do with BP_Arduino) have been copy-pasted from another map that has the reference to BP_Arduino, but i didn't copy any of those, so why is it present in Untitled3?

Is there a way to fix these "ghost" references in a map?

[summer dock]

Have you checked Reference Viewer -> R-click > Show referencing objects list?

[chrome cloud]

Untitled3 is nowhere to be found

[summer dock]

interesting... not sure how to proceed from there

[chrome cloud]

my thought was, since i copied stuff from a map to another, for some obscure reason the externalActors references are still present, but in perforce, in the externalActors folder regarding the new map, stuff is missing so it is not there, but for some reason it's still referencing stuff from the original map

Man this is such a PITA, i just wanted to chunk my chapters separately and it's being so problematic

[summer dock]

"Pain is Fun" - ancient gamedev motto

[chrome cloud]

not masochist enough i guess

[hexed hearth]

No. Material is fine and loaded already. I think it's some binding delay or caching with wrong offset or something which does not occur in Editor mode. The hair is floating about estimated 50 units above the head but following the animation already. After 10 seconds and without any further action the hair fixes itself and snaps perfect to the location it should be. I started with just choosing the binding asset for the groom component as usual. I've found some youtube videos that describe some bug which requires to remove the assigned binding asset from the groom component and manually assign it at begin play afterwards. I tried that... but did not fix the delay. If it would occur in editor mode I can probably try to debug and figure it out but it's fine there (I've not found anything in the logs either yet). If I take a very, very, very close look into the character bp in editor when I delete and attach the groom component from scratch again then I can see for the friction of a second that it binds the hair with some offset above the head until it immediately places it to the right location. But whatever takes a friction of a second in editor when you assign it for the first time seems to take many seconds in packaged mode. I've other groom assets that where created, exported and imported exactly the same and they work fine (reimport does not fix anything either).

[heady fable]

hey guys, how are u guys handling swapping icons from one platform to another? chatgpt is telling me that i can just
[PlatformAssetOverrides]
+Platform=PS5
+AssetPath=/Game/UI/Icons/PS5/*
+Platform=Windows
+AssetPath=/Game/UI/Icons/Windows/*
+Platform=XboxOne
+AssetPath=/Game/UI/Icons/Xbox/*

but i think its just telling me that these folders will be included in different platform builds, but not actually swapping the assets?

[summer dock]

I thought each platform had their own areas in configs

[hexed hearth]

However I was able to reduce my issue in meanwhile somehow. Generated some cards (but did not use them) via the cards plugin. Changed some of the "Project ..." settings in physics. Now the groom is attached at the correct location in packaged. It only takes about 10 seconds until the simulation starts. Hair are 100% stiff before that point in time. So it's again that seconds delay but does not look so horrible anymore. After a few secs groom simulation starts and drops smooth. I can accept that. Its not perfect but does look more like loading delay and less than a bug (like it did with the offset).

[heady fable]

what do you mean?

[summer dock]

Like for the app icons, I have separate fields for Windows, IOS, Android.

[weary junco]

i forgot if you were using metahumans or custom grooms but if its custom character there could be a collision box that pushes hair to top by default, if there is no collision or something idk how to solve it i can only recommend you to delete unreal engine and download again

[summer dock]

delete unreal? this seems like an unusual solution. There is option to verify engine, for example, if it's launcher engine

[weary junco]

that's for delete saved or compiled data that inside ue5, idk if verify works aswell

[dull phoenix]

Someone help me with this pls

[vagrant marsh]

My main drive that Unreal is installed to is getting a little full so I plugged in an external drive to package my game to it. However, the packaging fails with an error saying the drive is full, and when I look at my drives, the drive with Unreal had been completely filled up and the external drive didn't even have any files in the folder I specified.

I wanna know why it's not packaging to the folder I told it to, and what folder it tried to package to instead so I can delete it and get some space back

[summer dock]

I wager even if you package to ext drive, the Intermediate and Binaries will still be big

[golden thorn]

I need to package my game so that it can run on PlayStation. I’ve already passed Sony’s initial review and received the development and test kits for free. then, I need access to the relevant documentation on Unreal, but I don’t have the necessary permission. I’ve contacted Epic, but they haven’t responded. What should I do in this situation?

[summer dock]

I would say be patient, big companies move slow... ping your contact once a week or something maybe

[golden thorn]

Thank you- -

[worthy hound]

Guys , I want to sell my project in fab but I don't know how to package it.
its will be a game template
can someone help me

[jagged cape]

in my shipping build the appdata/local/game_name/saved/config/windows folder gets overwritten to look like this every time the player closes the game

is that some packaging box i need to untick some where? I want to let players edit the ini files if they like. Even if i add a brand new Game.ini file it gets deleted each time the game is closed.

[serene quartz]

WOW, thats a big log file, any advice? What errors come up the most? Which errors do I need to focus on the most?

[winged moss]

The errors you focus on is all of them

This looks like an editor log rather than just a cook log on its own though

But I would typically just work down the list one by one and see the decreasing number of errors over time

[weary junco]

just focus on the files doesn't exist, like vtune or something, i guess you don't have visual studio 2022 ?

[winged moss]

that isn't even an "error" that is relevant

everyone gets that

the first relevant error is an asset with a malformed asset tag

[serene quartz]

I do

[weary junco]

i dont get it what is the problem when packaging, there is a lot of things, is there any red warning failure message ?

as sswires said probably vtune is doesn't matter

[serene quartz]

wait so if that's not the error log then where do you actually find the error log or whatever?

[summer dock]

Is fine. Packagin log starts at the point you see "runuat" in the log

[tawny trout]

hello, i have a problem with my packaged game: the game for now start with just a default level with 2 BP actors (a grid and a grid manager). The grid manager call the grid to populate cells (spawning a BP_cell for every socket called)

now, the problem is only when i package and run the game, in the editor it works as intended. I can replicate the problem in the editor if i exclude the grid calling by the manager.

seems that the game doesn't load the grid in time for the function

Any idea what could it be?

PS - the problem is kinda recent: a week ago was working, i don't know what i introduced to create the problem

[weary junco]

try packaging it with debugging mode and add print strings to see if it works

[tawny trout]

uhm what is debugging mode?

[weary junco]

my game was crashing while i package my game in 1 level, i managed to fix it with delete cooked inside folders

you package a game with 3 mode shipping debugging and other

debugging mode for bugfix

it packages like its project

[tawny trout]

oh ok, what's differ? i can use debug only nodes like print string?

[summer dock]

That is the most important

[weary junco]

i didn't test it but just give it a try

[tawny trout]

ok thanks i'm gonna try

[weary junco]

if its working in project and not in package there is nothing else to do except debugging mode

np

[tawny trout]

i noticed there is one button missing from my interface too

i think i found the problem https://i.imgur.com/j52CgaL.png

i used a "get component by class" to get the static mesh component of the grid blueprint, and it output the wrong mesh.

i suppose i can fix it using get component by tag

nice, now it works: i love you 🙂 @summer dock @weary junco

i learnt something very useful today

[serene quartz]

But I still cant package it, because it abruptly stopped 😂

[summer dock]

search the log for "error" lines

[weary junco]

i agree with karma just see for error lines, if there is no error just look for end the of log

[hallow field]

Has anyone else tried running a 5.6 project on Steam Deck?

I am evaluating whether I should upgrade a project to 5.6, but it crashes with a DxCoreAdapterFactory error, which leads me to believe there is some new feature or DirectX API call in 5.6 that Proton does not yet support.

[hallow field]

Update: I packaged a build for Vulkan and it runs great on the Deck.

[viscid hare]

does anyone know how to open any game in the unreal engine editor because I would like to edit hello neighbor 2 late night shift fan game and I would like to edit a few things I tried to open somehow through uproject and there is no source folder somehow it didn't work for me and of course I mean the project from the unpacked pak file and does anyone know how to do it And then for example export it so that I could change it in the game or does anyone know anything on this server?

[summer dock]

not sure if any moddb people are here... https://www.moddb.com/games/hello-neighbor/mods

try searching on their forums maybe

[tawny trout]

Maybe a stupid question and maybe not the right channel to ask: is there a way to set on the fly the resolution of a packed game?

when i try my game it's always at low resolution. I don't have built a starting menu or nothing for now, i need to only to see how it run at a specific resolution.

[tawny trout]

maybe there's some fast way to start with the play in editor settings

[tawny trout]

yes, i mean to start in the packaged game using the PIE settings

[summer dock]

https://m.youtube.com/watch?v=q2oo91qAg1Y&t=24s&pp=2AEYkAIB

[tawny trout]

thanks i'll take a look later altough i think it's time to learn to do a simple option menu, i don't think it will be so complicated

[weary junco]

3 is epic, 2 high, 1 normal, 0 is low setting, if u put this on your main menu it will be start with epic settings

for more information i recommend you to watch the video that Karma has been posted

Hello there! Im doing some Mobile testing for a simple app but in order to pack for ios i need xcode and a mac, is there anyone here able to pack it?

[summer dock]

Best bite the bullet and acquire the mac if you really need to do that work, or look to hire somebody properly. Offloading work onto people here is a bit questionable...

[smoky tide]

Hello there, i am trying to package a game for IOS, after a lot of tries, I finaly have only 1 error left which is : The Following url schemes found in your are not in the correct format : {XX_XXXXX_XXXXX_UE5} . I've tried to rename the project manually, by duplicating the project and renaming it this way. And by specifying in the Mac :published app name. But nothing works, even though the xcode project file has the good name, it is rename by the old name inside xcode. I beg for your help 😭😭😭. So freaking difficult working with apple

[low cobalt]

First of all it is not any comercial project just a small study on UI and responsiveness, wich takes me 2 min of andoid build second no one said for free if anywho wants to contact me will share further details, but no i wont be buying a mac for a small study test, and no one its offloading work but you seem to offload your pretentious opinion 🤟

[summer dock]

Then lay out the terms up front and post in the right place. #freelance-jobs

[summer dock]

Ive never seen this. XXX_ue5 is sonehow related to your project naming?

[smoky tide]

It's the name of my project, I've just replace the letter with X, since it's not that important

[summer dock]

Im not at pc, but i would search the engine source for that particular error message to understand what exactly triggers it

[summer dock]

Or is the error coming from AppStoreConnect on validate/upload?

If you are able to rename project, make sure you delete Intermediate+Binaries before rebuild + submit

[smoky tide]

I've found a way I think, still get an error but from the xcode version now, so might be good, I'll check tomorrow

But basically my C++ class kept the name of my old project, and it kept regenerating based on that

By deleting intermediate and source, and restart the engine, I had the option to use the knew project name for the c++ class

I'll keep you in touch tomorrow 😜

[smoky tide]

Yeah, that on the validation upload it happen

[summer dock]

Big hassle : (
Hope you get a solve

[dark vapor]

Hey everyone! We recently upgraded from 5.4 to 5.6 and are having some issues with shipping builds. Development builds and PIE run perfectly fine at 60 FPS, while shipping builds don’t even reach 1 FPS. No difference between them other than selecting "shipping" in the project launcher.

We tried different packaging configurations, removing assets and blueprints from the scene, resetting project settings, deleting the intermediate folder, disabling plugins - nothing seems to work. Building other projects, on the other hand, works just fine.

Does anyone have an idea what could be causing this or any tips how we could debug it?

[shy narwhal]

Hi, I will be grateful if anyone can take a look at this problem, I cannot find a solution: https://forums.unrealengine.com/t/override-config-ini-files-after-installing-shipping-build/2586469 Thanks.

[proven stone]

I've not observed any slowdowns in shipping builds - especially not as large as this, so, try Testing configuration instead of shipping, just to see if it also does it (testing is easier to debug compared to shipping) - and if not, just hook it to some external profiler (unreal insights won't work by default since they're not part of shipping builds - although iirc there are way to compile-in insights support)

TL;DR: Profiling

[dark vapor]

Thanks, I’ll look into the testing configuration next, then. Using Insights for shipping builds seems to require building the engine from source, which I haven’t done before and wanted to avoid if possible, but I guess I’ll have to bite the bullet eventually. Was hoping someone might have run into a similar issue with shipping builds in 5.6 before, but alas...

[proven stone]

iirc there are other profilers and not just unreal insights, they might not give you as precise view as insights, but they could help narrow it down at least a little

[dark vapor]

I'll look into it some more, but it seems pretty much any kind of debugging tool in shipping builds, even just enabling command lines, requires building from source

[proven stone]

I think in C++ land that might be true, I'm used to C# and other managed languages where you can pretty much attach external profiler without the program even knowing about it

so yeah, you'll probably have to compile engine from source

[primal thorn]

hello are PAL (primary asset labels) working in 5.6? i want to package some levels and bps that are referenced through a json, so it doesn't create a hard reference so they don't package by default

i created a PAL on the folder with the levels and bp, set to label all in the folder recursively

if i try to delete a level it says that it has a reference to the PAL, so it's labelling, so why isn't it packaging? is there any other step needed besides creating the PAL?

[brittle geyser]

can i send multiple "-UbtArgs" parameters? if so how do i do it? should i do like:
-UbtArgs="-Arg1 -Arg2 -Arg3 -ProjectDefine:MyDefine" ?

or:
-UbtArgs=-Arg1 -UbtArgs=-Arg2 -UbtArgs=-Arg3 -UbtArgs=-ProjectDefine:MyDefine
?

[summer dock]

Yes, first style

Hi Braintrust! I’ve got another build graph related question, I’ve got a project that’s using custom modules, the build graph I’m using appears to be building and linking the modules correctly but fails to find it in the cook stage. Is there anything I’d need to add to the modules themselves in their build/target files or some extra tagging I need to add to the build graph itself to make sure it finds everything correctly? Thanks team!

Also, I figured out my BootstrapPackagedGame issue! I needed to set the TargetBuildEnvironment to shared in the BootstrapPackagedGame target file, there’s a conditional in UEBuildTarget.cs in the UBT source code that relies on that setting that overrides where it sends the build products if it isn’t shared which was causing issues.

link to the build graph I'm using: https://github.com/RedpointGames/uet/blob/main/UET/Redpoint.Uet.BuildPipeline/BuildGraph/BuildGraph_Project.xml

[ruby lava]

Hello everyone, please help me with this problem.
I'm trying to package the iOS project, and I've transferred all the certificates from vmware, but the engine is complaining. Why is that?

[ruby lava]

I don't using C++ in this project.

[summer dock]

The first error is not shown in the log snippet. The second error says your remote compilation setup is lacking.

[ruby lava]

the first error I didn't have to hit, but with the second, I don't need a remote compiler if I don't use C++ and plugins ?

[weary junco]

disable fab plugin, are u using metahumans?

[proven stone]

you cannot build iOS or Mac without a mac

there is a way to setup remote building which is what it's saying you need to do

and you need remote build environment to be set up for building iOS any time

since it has to build and package the iOS application package, which is done through xcode

here is full official guide on how to set things up https://dev.epicgames.com/documentation/en-us/unreal-engine/creating-remote-builds-of-unreal-engine-projects-for-ios

Hello! I am stuck with an issue, when i build my game, it always gives me error of Not enought memory, but i have 32gb of ddr4 - 4133mzh and also 32gb of virtual memory, and it still crashes the build, how to fix it or give it more ram to wark with?

[summer dock]

1st sanity check : can you package a blank / template project?

[dark junco]

Trying to build from TopDown Template and the build is a Third person Character in flying mode? What is going on? Can someone help me?

UPDATE: I solved this one. Apparently if you create a Character and you call it Player Character for Unreal it editor will be fine, but when you build he loose the references. I solved simply renamed the file.

i tried without Package game data inside .apk = false
then the build is succuss but when i install apk in my mobile iam getting OBB file didnt not found , can any one help me with these?

[simple eagle]

Hello, I'm having a problem packaging my game for the quest 2, build is successful but the game won't open, I get this error which I believe is the culprit!

[wicked kindle]

have you put the .obb files?

[vital wind]

Where to put?

[wicked kindle]

Android/obb/com.yourcompany.game

I don't know if you can see the folder since the latest versions of Android hide the folders.

[winged wasp]

Hey all, probably a noob issue here. I have use pak files enabled in my project settings. Im using the project launcher to package my game, and its not generating any pak files. Instead, im winding up with an exe and an engine and project folder that literally contains my entire project with .uassets. Anyone know why this is?

This is what I wind up with, both the engine and stickaround folders have my project files in them. No .pak files

[winged wasp]

Figured it out, project launcher doesnt care about your proejct settings. You have to turn on the "use one pak file" or whatever its called.

[toxic crystal]

Been on this all day and GPT has me running in circles. Would appreciate some help with packaging.

From what I gather, to cross-compile a Linux dedicated server from a Windows machine using UE 5.5.4, I need to:

• Install clang 18.1.0
• Setup a ProjectNameServer.Target.cs

I installed the toolchain and created the ProjectNameServer.Target.cs file. I have the option to build a Server on Linux.

I click on build and after a few minutes the build fails.

[rigid forum]

Hi
Why does my Android build work fine as an APK, but when I create an AAB file, upload it to the Play Store, and download it, the app gets stuck on the loading screen?

[summer dock]

Sounds unusual. Upload a dev build and log things out. Android studio logcat for the win

[rigid forum]

ill try to upload a dev build can we upload dev build ?

[summer dock]

Yes you can. We actually have two separate apps, dev and the final shipping game to keep things completely and clearly separate, but thats just for our convenience.

[rigid forum]

you think i need to set ot rest more options ?

[rigid forum]

f I uncheck "For Distribution", it creates an unsigned bundle that I can't upload — but if I check it, it creates a very small bundle, and when I try to upload it, I get an error saying ".obb file not found".
Why is this happening, and how can I generate a Development build that is signed, self-contained, and uploadable without requiring an .obb file?

[summer dock]

For Distribution is a different config from dev/shipping.

[rigid forum]

what i am doing wrong ?

[summer dock]

Not at pc now. But there afe 2 different configs : one is dev/shipping, other is ForDistribution boolean. You want dev + distribution(true)

[rigid forum]

yes its

[summer dock]

Im afraid I am not at pc. But guaranteed it can be done. Should just be the build config change, nothing else.

If you can package shipping aab, then just change that.

[rigid forum]

yes you are right it should be but when i create build its only 78 MB and i upload got the above error that .obb file missing

[summer dock]

I have to suspect something else was changed as well. Inspect build logs

[rigid forum]

I think there is still something is missing

[flat comet]

Hi guys, has anyone migrated from 5.5 to 5.6 with mutable assets in the project? The build crashes with Assertion failed: MaterialPin [File:D:\build++UE5\Sync\Engine\Plugins\Mutable\Source\CustomizableObjectEditor\Private\MuCOE\GenerateMutableSource\GenerateMutableSourceSurface.cpp]

[flat comet]

never mind, found a solution

[winged moss]

Are you not going to share it? People frequently search the chat history for solutions first

[flat comet]

I gave up on fixing this, I went to edit the source code, so I don't think my solution is valid :)

[winged moss]

Fair enough

[west granite]

Hi there. I'm trying to toggle RayTracing on and off at runtime according to the guidelines here, but it doesn't seem to work for me.

It says I need to include these commands to my WindowsEngine.ini but I don't have this file in my packaged build nor the project files.

[late trellis]

Hello, can anyone help me out with packaging? I always get this error but I dont know why

[late trellis]

nevermind, just had to update visualstudio

[summer dock]

Create the file yourself. Not all .ini files exist by default

[proven stone]

You need to be a bit more specific than that. I'm currently not aware of any "shipping config" problem in 5.6

[weary hatch]

Hey folks! Does anyone know how to build “UnrealEditor-Cmd.exe” but for a specific project that would output something along the lines of <project>Editor-Cmd.exe? I’m still investigating the missing module during the cook issue and I’ve been told using that executable might resolve the issue hence why I’m trying to track down how to build it 🙂 Thanks everyone!

[proven stone]

What way are you packaging? Command-line, buildgraph, editor quick actions, project launcher etc.

I heavily rely on cli and buildgraph for our ci and everything… and when I tell it to build shipping it builds shipping… so knowing what method did you use would help to narrow the scope down.

[winged moss]

I would take a guess it's via the editor because this frequently comes up but I'm not exactly sure of the cause

And since I'm generally not a fan of packaging via the editor, I usually direct towards the CLI/project launcher since that doesn't have the overhead of a running copy of an idling editor

[proven stone]

It also could be issue with the new project launcher in 5.6 etc… and that’s why I’m asking… bur yeah… pretty sure its one of the visual ways of packaging rather than cli

[broken mortar]

I have defined DataTables in subclassed DeveloperSettings. I am using a Primary Asset Label to explicitly add them and set "always cook" . I also have this config in DefaultEngine.ini to try and get UE to package the DT with no luck. What step am I missing?

[/Script/Engine.AssetManagerSettings]
PrimaryAssetTypesToScan=(PrimaryAssetType="PrimaryAssetLabel", AssetBaseClassName="PrimaryAssetLabel", bHasBlueprintClasses=False, DirectoriesToScan=(Directory="/Game"))
PrimaryAssetsToLoad=(PrimaryAssetType="PrimaryAssetLabel", PrimaryAssetName="PAL_AlwaysCook")

Assertion failed: ZoneDefinitions.IsValid() [Plugins\ZoneSystem\Source\ZoneSystem\Private\ZoneManagement\Zne_ZoneManager.cpp] [Line: 48]

I should mention this works in PIE without issue.

[winged moss]

Is this vibe coded? There are some redundant specifiers there. Are the settings being written to DefaultGame.ini?

Is the asset actually under the game contents or the plugin contents? Are you able to verify if the asset is being cooked?

[broken mortar]

The redundant Config on the UPROPERTY is fixed. I didn't see it at first and thought it was missing. The PAL is in Game contents the DT is in plugin contents. There are many entries related to thsi being written to DefaultGame.ini, what should I be looking for. Vibe Coding?

There's this:

and this:

I'm assuming Assertion failed: ZoneDefinitions.IsValid() means it was not cooked.

[winged moss]

AllowedClasses meta is redundant too. Also the asset is in a plugin so therefore not /Game

[broken mortar]

THanks, so the PAL and DT need to be included in the directories to scan ?

Seems to take away frmo a registry's purpose

[winged moss]

As a last resort yes, but I would've thought being in a CDO would enough to be included in the cook

[broken mortar]

I'll give it a shot

No dice

:/

I'm getting a strange immediate crash on launch.. Can anyone help me understand what the heck is going on?

[proven stone]

seems like something you did with the UAudioCaptureBlueprintLibrary - more specifically with the GetAvailableAudioInputDevices function then feeds itself to UI (slate/UMG) but slate can only be modified from main thread or slate thread... but the GetAvailableAudioInputDevices is called on audio thread

[broken mortar]

Asset is actually being cooked.

[broken mortar]

Simple fix as always!

Changing how I was storing them in the subsystem resolved the issue. So, in DeveloperSettings, they're TSoftObjectPtr member variables and in the subsystem they're now just TObjectPtr member variables. Whoops!

// (Get from ZoneSettings)
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Zone Manager")
TObjectPtr<UDataTable> ZoneDefinitions = nullptr;

[winged moss]

Well yeah, it not being a hard ref would end up with the asset being GC'd. The editor likes to keep asset around in memory

I can package a Windows version of my project but if I try to package an Android/Meta version I get this message in the output just beofer fail - - Can't make an APK without the compiled .so' - any ideas what this might be? I have all the correct Android studio versions installed according to the docs and all the Adnroid/APK project settings set according to docs

This is the log

hai can i ask for help regarding DLSS? im using UE 5.6. already download DLSS nvidia latest (for UE 5.6). i follow tht youtube step. it does work. im having problem when packaging into windows, it says build failed. something to do with streamlineDLSSGblueprint
https://www.youtube.com/watch?v=ZQnXCW2CAhI&ab_channel=TUF

[proven shuttle]

ok i try to put the plugins in my project. and it works (can package)

[steep vine]

so u just had to put the files in ur project plugins right

[vital wind]

Hello everyone,

I'm currently planning to develop a mobile game for Android with a structure similar to PUBG Mobile. Here's what I’m trying to achieve:
*Users will first download a small-sized APK or AAB from the Play Store.
*After launching the app, it will download the core game assets (base content).
*Additional content like different maps or modes will be downloaded later as needed.
This approach helps in reducing the initial app size and improves content management for larger games.

What i have done till now
*I'm using Unreal Engine 5.4 and have already enabled chunk-based packaging to split assets into multiple .pak files.
*I'm using Android App Bundle (AAB) for packaging instead of APK + OBB.
*The AAB build generates folders and asset packs which I’ll share (see attached image).
*My goal is to dynamically download only the required chunks, similar to how PUBG Mobile handles maps or features.

I need help setting up a system that:
*Automatically generates separate asset packs or .obb/.pak files for each chunk.
*Allows downloading these asset packs at runtime based on user selection or need.
*Ensures proper integration with Google Play’s delivery system (such as Play Asset Delivery or Play Asset Delivery + Cloud Storage fallback).

[vital wind]

I've been able to generate multiple OBB files using the current Unreal Engine settings. However, I noticed the following issue during packaging:
*The main OBB (main.obb) includes all of the .pak files.
*The patch OBB (patch.obb) only contains pakchunk0_s1.pak, which appears to be a sub-part or a split of pakchunk0, likely due to size limitations.

*I want the main OBB to include only pakchunk0.pak (the base content).
*The rest of the content (e.g., pakchunk1, pakchunk2, pakchunk3, etc.) should be moved to the patch OBB or be handled separately (via Play Asset Delivery or manual download).

[serene quartz]

Do I need Win UI to package?

So I wasnt getting this message before...

what I did is change Cache Derived Data folder destination and thats how I got to this

[winged moss]

the DDC location isn't going to affect that

did you install the correct toolchain and Windows SDK?

[serene quartz]

I fixed it

btw does anyone know what this error means?

````LogPlayerController: Error: InputMode:UIOnly - Attempting to focus Non-Focusable widget SObjectWidget [Widget.cpp(957)]!```

I have many many many widgets, do I have to go into every single one of them individually to see which one is fucking up?

note that not only do I have more than just one widget blueprint, but my widget blueprints inside of them individually also have a lot and lots of widget components , so I'd have to check every single one individually isolated from the others

[winged moss]

add a breakpoint to whatever emits that error and that'll probably tell you

[serene quartz]

it would be impossible to know, and id have to change up and re-package to see if i get this error

[serene quartz]

how do I add a breakpoint to packaging output logs?

[winged moss]

I thought this was a runtime error

I would not expect this to happen during packaging

unless you're doing something weird in a construct script

[serene quartz]

I have many blueprints and therefore many many many construction scripts

[winged moss]

well I'd start with the player controller one

you can still debug the cooking process by attaching from VS/Rider to UnrealEditor-Cmd.exe

inspecting the callstack should tell you where it's coming from

also in general, you shouldn't be using the construct script for runtime things, like creating and managing UI

BeginPlay would be better for that

[serene quartz]

the construction script in my controller is not attached to anything

and its not letting me delete this function

[winged moss]

then you're probably going to have to debug and look through the ProcessEvent calls

[serene quartz]

btw im not cooking, im packaging, whats the difference between the two?

[winged moss]

packaging is build and cook

and this presumably comes from the cooking stage

[serene quartz]

do I have to know any C++ for that?

[winged moss]

yes since you'll need to know how to look through the callstack and understand what you're seeing

[serene quartz]

wont it still package if I only have 1-2 errors ?

or red text lines

[winged moss]

any error during the packaging process fails the process

[serene quartz]

are there any ytb tutorials on how to do that?

[winged moss]

No idea

[serene quartz]

so I should just start learning c++ and how to work on debugging my project with c++ or just convert my entire blueprint project into c++

I kind of understand C++ and how it works

but I never tried C++ with Unreal Engine

[winged moss]

sure. it's easy enough to convert and existing project by adding a C++ class from the editor, that'll generate everything it needs to become a C++ project

the only thing you really need to tell is which BP is calling SetInputMode on the player controller with a non-focusable widget

in BP that'll be Set Input Mode UI Only where the Widget To Focus is a widget that's not focusable

so that probably narrows it down

the main suspect would probably be a main menu since that's likely going to try and focus a widget on creation

[serene quartz]

So it's likely this one

is it that I have this not connected to my widget?

[winged moss]

no because that error will only emit if the widget to focus is valid

though it's painful to see EI input actions refer to specific keys

but input actions are not going to run during cook

though what calls "remove inventory"?

also btw "get player controller" is kinda redundant if this/self is a player controller already

[winged moss]

that doesn't have a call to "remove inventory" in it

Clean_Controller has an event called "remove inventory" so it's handy to know what calls it

but that would require it to use the "Is A" branch, which does the opposite

this error should happen in PIE too

[serene quartz]

but is that where the problem is? the problem looks to be in wb_pause_menu, right?

[winged moss]

well no, I don't have your project in front of me

I can only assume certain things based on the information you share

[serene quartz]

yes but the error is on a UI only node

only the bottom piece of code holds a "UI only" node

Also here's where the remove inventory function is called

since you asked

[serene quartz]

though it's painful to see EI input actions refer to specific keys
what are "EI" input actions?

[winged moss]

enhanced input

[serene quartz]

I think the problem lies here, I turned it to focuseable, before it was unfocuseable

[winged moss]

yeah that's what causes the error when you try and focus a widget not focusable, but that's still just guessing

it's odd that it'd be trying to focus a widget at all during packaging

[serene quartz]

BlueprintLog: Error: Cannot convert the construction script!```

I got 2 more errors

[winged moss]

well which BP is it

[serene quartz]

so before you said, adding a c++ class would convert my project into c++ or something of both(hybrid)?

there's no way to know

[winged moss]

this still suggest you're using a construct script for stuff it shouldn't be used for

it makes your project a C++ project, it doesn't do anything to your existing blueprints

[serene quartz]

then can you convert it back to blueprint later?

[winged moss]

I'm not sure I would recommend doing that

a project being a "C++ project" doesn't stop you from using BP, in fact, it's expected

[serene quartz]

I created a c++ class

but now i still dont know how to debug any stuff

related to the packaging errors

its just a class I created

[winged moss]

while the cooker is running, from VS, you can Debug > Attach to process > search "UnrealEditor-Cmd.exe" and then attach to that, make sure a breakpoint exists for where that error is shown

[serene quartz]

I thought it was going to create a copy of all my blueprint projects automatically into c++ and then that way it would give me something that would allow me to debug

[serene quartz]

so first I have to press cook/package, then open the cmd?

[winged moss]

and if you don't have editor symbols downloaded, then you'll need to download them in order to be able to add breakpoints to engine code

[serene quartz]

how do you do this attack to process?

[winged moss]

the ways I just said

[serene quartz]

you open VS and you see this as a button somewhere?

[winged moss]

I already said

there's a menu

it says "Debug"

you click it

and then click "Attach to process"

this opens a window, where you select a process to attach to, for the cooker, this will be UnrealEditor-Cmd.exe

[serene quartz]

ok gotcha

but before that...

before we get there, which one of these will you open?

[winged moss]

this is from VS, that's why I said VS

[serene quartz]

open vs or new c++ class?

yeah but how do you get in the vs in the first place in what im asking

you get by creating a new c++ class?

or by clicking this "Open Visual Studio" option

[winged moss]

it just opens the solution file

which is generated in the root directory of your project

[serene quartz]

here?

[winged moss]

....

in file explorer

[serene quartz]

ok and I assume I do it through .snl

or through this?

[winged moss]

"generate visual studio project files" is to create the sln

you only need to run this if you move the project, add new C++ files manually, or change any build settings

[serene quartz]

oh so everytime I fix an error and change build settings I will have to regenerate a new visual studio project files?

[winged moss]

I didn't say fix an error

and "build settings" would be a modification to the Target.cs/Build.cs files

[serene quartz]

ok here's the class I made

it's just an empty class

I attached to process

[winged moss]

damn that lack of cleartype, but the class doesn't matter, this is just for attaching the debugger

and did you add a breakpoint to what is logging the error?

you'll need to

and you need to add the breakpoint before it happens

[serene quartz]

oh, so breakpoint in the line of code here?

any line ?

[winged moss]

no, where the logging happens

breakpoints stop execution when the line of code is hit

[serene quartz]

I cant add breakpoint to the logs

its read-only text

[winged moss]

it's easy enough to find in all files "Attempting to focus Non-Focusable widget" and add a breakpoint to the UE_LOG line

which should be in PlayerController.cpp somewhere

[serene quartz]

I attached it to my Unreal Engine

also for some reason

now the packaging fails too fast

[winged moss]

UnrealEditor.exe is not the cooker, the cooker runs as a separate process, UnrealEditor-Cmd.exe

[serene quartz]

where do i find that?

there should be a library somewhere correct?

[winged moss]

???

[serene quartz]

where I should see my content browser

to open the controller?

[winged moss]

it does feel you read half of what I put

[serene quartz]

the equivalent of the controller converted in c++?

[winged moss]

??????????????????

the content browser has no relevancy to C++ code

[serene quartz]

ok i see

[winged moss]

every BP class is based on a native actor class of some description

also before you mess with more debugger stuff. did you follow the advice in the top pin so that you would know what is getting cooked when the error is logged?

[serene quartz]

this?

[winged moss]

yes

what

[serene quartz]

ohhh sorry

you said progress settings

my bad

[serene quartz]

ok done, btw is there something like a keyword I can search on ytb to find a step by step video about this?

or a search prompt?

[winged moss]

I'm not someone who learns from videos and a lot of the content on YouTube isn't great to begin with

But now if you cook, it'll show exactly which asset is being cooked and why

so when the error happens, the lines before it should show more info

[serene quartz]

since I created the C++ class now the cooking crashes after 1 minute or 30 seconds

wheres before it would take like hours and would not crash

[winged moss]

Well you need to look through the log

Or share the log

[serene quartz]

this log?

coming

[winged moss]

I mean all of it, as text

[winged moss]

There are quite a few BP/asset issues in that, and none of them the original one

as always you just search error: and work through them all

and I don't see much evidence of that project setting being changed

[serene quartz]

so why is that happening?

PackagingResults: Error: Unknown Cook Failure

[winged moss]

I feel like there's more selective hearing happening

you search error: (yes, with the colon) and you get them all

the very first one is because your game instance class is set to an invalid class

[serene quartz]

ive seen that error

but now its not letting me raech there in the first place at all

[winged moss]

what do you mean reach there? it's a project setting

[serene quartz]

because it loads for 30 seconds and then stops without explanation

it stops in this error

PackagingResults: Error: Unknown Cook Failure

Unknown

[winged moss]

that's not the error

again, share the log if you're unsure but you get that because there are other errors above that you have to comb through

[serene quartz]

ok i deleted the log file, and Ill try to re-package

[winged moss]

some actual errors from the log:

[serene quartz]

also now im getting this when I start my engine, not sure if its related

not sure what module this is referencing

[winged moss]

that's because you added a C++ class and didn't actually build the code

[serene quartz]

terravive is the name of my project

[serene quartz]

ive deleted this btw

so this is old log, thats why I need to re-do it

I'll let this wait

I tried to fix redirectors, but it took too long and decided to restart

because fixing redirectors are always kind of bugging

and they are related to alot of errors as I've seen it

so I have to take it maybe folder by folder sometimes so that it doesnt do too much at once

[serene quartz]

ok now packaging goes like normal

[vital rune]

Does anyone know what this problem is? I deleted the water from the levels and this still popped up

[vital rune]

OK I fixed that, but now I have a problem where it only builds the Main menu, the level select, and none of the actual levels. if I select Level 1 it goes back to the main menu

[serene quartz]

I finally fixed all the redirector errors, it took a surprisingly long time and effort, I thought it would just be a right click on content and fix/update but that didnt work, everytime I tried to do that it would not work because I had some corrupted files and I had to go folder by folder individually, so there was a little bit of folder-ception going in the folder matrix, but I finally got it

Updated logs

also whats funny is, a lot of these errors here, keep comign back, I remove a lot of these useless files and blueprints and stuff that are no longer used, just junk stuff

and then somehow my delete action doesnt get saved or smth?

[proven stone]

You have to add the maps you want to include in the cooled game in the “maps to cook” or whatever the option is in the project settings (sorry for imprecise info… am on phone and it’s hard to check)

[vital rune]

I got that working a bit ago! But thanks! Now there only now there is a problem where level 3's nav mesh isn't working

Even though it was working in level 1 and 2

At least I think it is just 3, I am unable to get to level 4 in the built version because of the enemies (they are in the way and I can't get past them without dying)

Hi everyone,
I'm currently trying to package an iOS build, but I'm encountering multiple errors related to unused variables. For example:
Error: variable 'Result' set but not used [-Werror,-Wunused-but-set-variable]

Does anyone know how to resolve or bypass these warnings during the packaging process?

[winged moss]

ApplePlatformCompilerPreSetup.h has this warning ignored so that's odd, but if this is in your own code I would ideally fix errors and make sure you're doing CI builds with a Clang-based platform regularly

[rigid forum]

Mostly not in my code, engine classes

[winged moss]

that's even stranger then. not worked with iOS, but I'd check your build environment matches what the engine expects, there aren't any weird Target.cs settings, and go through any modifications to the engine (if any)

[rigid forum]

it is working fine for android on windown machine , but not on mac for ios

[vital rune]

I am still having this issue and now it doesn't even work in the editor now

I have no idea what is going on or how to even fix it, I built all levels, I cooked the content, I have absolutely no idea of what to even try next

[lime carbon]

Can anyone point a direction on how to debug cook dependency? Let's say we have specified a map A to BCR -MapsToCook, but while checking the output log, we found another giant map B got cooked as well (among many of others). I have tried to use Reference Viewer and the Find Path Tool but there is no path between map A and map B. I have also checked the references of all the always cook assets and they do not reference map B in any path.

[winged moss]

top pin

[lime carbon]

😄 thanks dude, I'm gonna have a try

[winged moss]

and while there might not be a direct path between maps, you would have to think about a situation like hypothetically having a level selection widget that's referencing map B via a soft reference, if that widget is referenced by your main menu, then that's a way it gets included in the cook

[lime carbon]

I followed the instigator chain from log and finally find the map is referenced by "StartupSoftObjectPath", do you know what is it?

[winged moss]

could you share more info from the log?

[lime carbon]

I just figured it out😄 the packages loaded during engine startup are counting as StartupPackage and the soft references from those StartupPackage are probably called StartupSoftObjectPath. So yes our project has an engine subsystem which loads up some datatables while init and those tables reference the level somehow and finally cause the wrong map got cooked.

[winged moss]

alright yeah, though it seems kinda bad if an engine subsystem CDO is loading assets

Hi there! Got a problem when trying to build in 5.6 using the console:

Dependant modules 'DNACalibModule'
Non-editor build cannot depend on non-redistributable modules.
BuildException: Non-editor build cannot depend on non-redistributable modules.```

So, I could mark DNACalibModule as an Editor module in DNACalib.plugin? Looks like it's linked to MetaHumans. Anyone got this problem? Thanks!

[tight fjord]

I would create a new collision channel called water 2 and get rid of that first collision channel. What is happening is corruption somewhere and this datapoint isn't being looked at properly. Happens all the time with structs

what do you mean by "blocked by enemies" without dying??

[vital rune]

Since the enemies aren't moving they are always blocking the player path, they are supposed to move so the player can get around them

No matter what I try I can't seem to get the ai to work after loading that level

[sacred crown]

I am getting this Unknown Error and not sure how to fix it (Using Unreal 5.4)

little more info if needed

[tight fjord]

if you use a BT and BB, it means that the BB isn't getting updated properly and defaults to null. I had this issue in the past. You need to reset the BB value properly. In the editor, this isn't visible because that value is cached. In the actual packaged game, there is no cache and the value has to be set.
In your BT, make an action (i forget what it is called) that gets/sets the value in the BB properly

[tight fjord]

check the actual log file in the path indicated

[sacred crown]

which log file?
