packaging

[solar trellis]

show your Build.cs and Target.cs files and the full command line you are using to run the RunUAT.bat file

[ivory coyote]

So, as i've never used the command line method of building before, i just checked the docs and used epics assistant to try. it gave me this...

RunUAT.bat BuildCookRun ^
-project="C:/Path/To/YourProject/YourProject.uproject" ^
-platform=Win64 ^
-clientconfig=Shipping ^
-cook -allmaps -build -stage -pak -archive ^
-archivedirectory="C:/Path/To/OutputFolder" ^
-nocompile -nocompileeditor

and it worked. I also found opening the project launcher, making a new custom profile and choosing shipping works as well. but going to platforms > package project and having shipping selected will always do development instead.

I actually reinstalled the engine, deleted everything from appdata and the build, binaries, intermediate, saved ddc etc from the project and ran a repair of VS to try reset any preferences that could have been changed. the issue still persists so i have no idea whats changed.

I don't actually know where to look for the target.cs and build.cs I've always just done stuff in blueprints and building just worked. I only mentioned the target as when building it would generate a line about "UnrealGame-Win64-Shipping.target does not exist" and I feel like this used to be "ProjectName-Win64-Shipping.target"

the other bit of discovery i made is it was due to a plugin recompiling. I tested on a second machine and removed its binaries and intermediate to make it say it needed to compile when opening the project. as soon as it did this, the issue happens. I don't know why it originally needed to compile but forcing it to happen caused the issue on another PC. so now 2 PCs have the problem! but reinstalling unreal didnt fix it?! and its still an issue in a template project, like the fps template, i cant build that as shipping the normal way.

any of this help understand it more or am i just rambling?

[solar trellis]

Someone with more time may be able to dig deeper, why not drop a minimal template project that is broken on your side here for others and we can try to package shipping for you.

In addition, what is the command line from the log for RunUAT when you try to package from the editor? It will be in the Logs

[ivory coyote]

LogMonitoredProcess: Running Serialized UAT: [ cmd.exe /c ""C:/Program Files/Epic Games/UE_5.7/Engine/Build/BatchFiles/RunUAT.bat" -ScriptsForProject="C:/Users/Documents/Unreal Projects/MyProject4/MyProject4.uproject" Turnkey -command=VerifySdk -platform=Win64 -UpdateIfNeeded -EditorIO -EditorIOPort=62772 -project="C:/Users/Documents/Unreal Projects/MyProject4/MyProject4.uproject" BuildCookRun -nop4 -utf8output -nocompileeditor -skipbuildeditor -cook -project="C:/Users/Documents/Unreal Projects/MyProject4/MyProject4.uproject" -unrealexe="C:\Program

is it this line? i made a quick template n tried to build it, same issue and this was the bit i found for running the runuat.bat doesnt seem to specify shipping or development in it.

[solar trellis]

did you know that 3 backticks will actually give you code blocks in discord? hence making it easier for others to read and copy?

[solar trellis]

yep it is missing -serverconfig=%SERVER_CONFIG% -clientconfig=%CLIENT_CONFIG% and you are using Binary engine too which could be causing some issues? I'm not sure since I don't use it, we use Source build. You cannot build servers with Binary engine... you can file a bug report with Epic and hope they fix it in the next year or two

or you can dig deep into their source code and fix it for everyone else with a PR on their github

[outer frigate]

I've been told there's a way to attach a debugger to a shipping build and I'm very interested in learning more about that.

[winged moss]

I'm not sure what there is to learn? If you have a matching pdb and don't have some anti-cheat launcher which will block debuggers, you can just attach straight from VS

-waitfordebugger doesn't work in shipped so if it's a launch crash then you would need to use -basedir. a lot of this is covered by this article: https://dev.epicgames.com/community/learning/tutorials/dXl5/advanced-debugging-in-unreal-engine

[solar trellis]

did you figure it out?

[outer frigate]

Nnnnnope. Got so frustrated I had to walk away for a while.

Getting back into the weeds now.

[outer frigate]

I'm doing something wrong, I guess.

The build won't even succeed anymore.

Target file. There's a lot of stuff in the build log and it's not immidiately obvious to me where it's breaking.

// Fill out your copyright notice in the Description page of Project Settings.

using UnrealBuildTool;
using System.Collections.Generic;

public class CapstonePrototypeTarget : TargetRules
{
    public CapstonePrototypeTarget(TargetInfo Target) : base(Target)
    {
        Type = TargetType.Game;
        DefaultBuildSettings = BuildSettingsVersion.V5;
        //Everything outside these comments was what the project was building successfully with.
        bOverrideBuildEnvironment = true;
        bUseLoggingInShipping=true;
        bUseChecksInShipping = true;
        // End new stuff.
        ExtraModuleNames.AddRange( new string[] { "CapstonePrototype" } );
    }
}

"fatal error LNK1120: 8 unresolved externals" seems to be the point of failure?

Whatever the problem is, it was one of those three changes, since without them it can still build with the "Include Debug Files" .ini setting enabled.

Hopefully I can get what I need with just that?

[solar trellis]

So you are having problems building and you have an option there called bOverrideBuildEnvironment = true;
I never heard of this, can you tell me what it does and how to use it?

[outer frigate]

No freaking idea, it wouldn't build with the two that make sense and it told me to try adding that line in the error.

None of this is my wheelhouse, unfortunately. I managed to attach the pdb to the release build, but I don't think I'm good enough yet for anything I'm seeing to be useful.

I wish I could just get whatever this error is to happen in the editor.

I don't know what else to do.

[ivory coyote]

sorry not sure i understand needing a server. this was just a template project to test it wasn't any of my projects causing issue, it was the fps template. my projects are arch vis based so you are exploring buildings etc but they've never had an issue in the past. there are no servers/multiplayer stuff currently. it does build via that cmd line i used earlier and also via project launcher. its just the usual method i always used now does not work and will always default to development only.

noted on the backticks, thank you!

[winged moss]

None of this is to do with debugging shipping. You cannot override settings that require a unique build environment without using a source build

[lyric imp]

Hey has anyone here published a game on Steam for the Steam deck I’m curious on what the process looks like on the unreal end for getting it setup

[zenith idol]

So why do some specific FNames become invalid after packaging a game ? I've been having issues with using internal FNames such as "INT", "EXP" and "END". They work fine in the editor but in a shipping build these become invalid

[solar trellis]

never had that problem but I try to use long unique names that don't clash with engine ones

[zenith idol]

Do you know where I can see a list of names to avoid ?

[solar trellis]

EngineTypes.h or some other source file in the engine, just search for NAME_None and go back to where they define it, there are a ton of them there

[zenith idol]

Okay so I'm finding out this issue only applies to FNames when looking up FText in a stringtable. If anywhere during that process specifically an FName with a bad name is created it'll become invalid in a build. It doesn't seem to matter for FNames that are used for anything other than text lookup though

[solar trellis]

use FString for debugging only
use FText always (supports localization)
use FNames as a quick hash lookup for sockets, bones, traces, etc. and it should NEVER be seen by players

I hope that helps

[zenith idol]

Well FString can also be used internally for text lookups. The FindTextInLocalizationTable node takes in FStrings as inputs

[winged moss]

though I'm not sure why in that instance you still wouldn't be using FText directly

[mystic atlas]

Is that looking up by localisation key or by localised value?

[zenith idol]

What do you mean ?

[mystic atlas]

Don't worry.

[lucid ruin]

Getting some weird errors when packaging, any ideas? I don't have any other errors that precede this.

[solar trellis]

build or cook? unable to see that attachment on mobile. post the top most error

[solar trellis]

I'm on desktop now and I've seen this sort of error when you are not checking for IsTemplate() and the like in your PostInitialize/BeginPlay type code and it is running and trying to load stuff with the cooker, so you'll have to attach a debugger to figure out which class or asset (UPackage) is doing this or look just above this message in your logs if it tells you which it is working on

[lucid ruin]

I'm pretty sure it was a corrupted file. I tried a bunch of verify cmdlets and always crashed a bit through. Added the project cleaner plugin and removed corrupted files and was good to go.

[fervent goblet]

I have a system setup where I package for DEMO and for full build with different build targets. I wanted to ask, what's best practise to exclude/include files from packaging directly from the build target?

Basically the build target for demo has a single global variable defined "GlobalDefinitions.Add("DEMO=1");" and we use a blueprint library to detect which datatables to select - but I can't figure out a way to exclude the full game datatable from packaging (likely, because it's a reference in the darn blueprint library...).

[winged moss]

then you'll have to move the reference out of there

[fervent goblet]

but I need the reference somewhere when packaging for full build. I don't want to keep fiddling with stuff everytime I package the two builds.

[winged moss]

I'd probably have the reference in a UDeveloperSettings (which would have to be soft) and then override that setting in demo-specific INIs using CustomConfig

the BPFL would read that setting instead of embedding the reference

[fervent goblet]

I was thinking of setting up a module for the full build...but that seems a bit easier

[fervent goblet]

Well, actually I had a need for a module and I ended up using it. HOWEVER, the full game datatables won't package at all now, because it's used with LoadObject in the module blueprintlibrary and won't get packaged...how do I set up module specific inclusion?

[winged moss]

hardcoding asset paths in C++ is always a bad idea. asset references need to be discoverable through the packaged levels and CDOs

[fervent goblet]

Sorry I'm confused. how else do you access datatable assets (or any assets for that matter) in C++ other than hardcoding their paths?

Oh, via blueprints that extend the c++...

[winged moss]

you generally don't have asset paths in C++, you do them through project settings and BPs usually

[solar trellis]

yep and don't listen to the other guy, we put default settings and hard code them in C++. we put all default values into a very specific folder under Content so that we know they are referenced in C++. generally speaking he is right but when you have a big team and people create new blueprints from your C++ classes, you generally want all of the default settings to be well defined there. others make default blueprints and go from there but in our experience they become corrupt overtime and cause more issues so we stick with putting only default values hardcoded in C++

[winged moss]

lol

hardcoded string paths are way more volatile

[fervent goblet]

yeah, I have a solodev project where no one else has access to the code so or blueprints, so string paths seem ok...

however! they do not seem to create hard references and exclude the files from packaging, which is a bit of a nuisance

[winged moss]

which is why I was suggesting the more data-driven approach of INIs. these modify the CDO of your UDeveloperSettings-derived class, so the cooker actually sees the reference

[proven stone]

Generally good practice in modern unreal is to use primary data assets, ini (Config uproperties) or the UDeveloperSettings as sswires said… or obviously passing objects as uproperty through BP exposed properties…. The rest is clunky and doesn’t scale to larger projects

[fervent goblet]

anyone happen to have references or how-tos for using these at hand?

[proven stone]

Since unreal can keep track of all of the references and warn you that you’re removing or moving assets that are referenced from ini etc. or automatically handle redirectors etc. but I’ve not had such luck with statically loaded assets in constructors etc. but I’ve not really tried this approach in eons so things might’ve actually changed since then

[fervent goblet]

I think making the .ini seems straight forward, just add to ProjectPackagingSettings +DirectoriesToNeverCook but where do I specify the .ini file to use with the build target?

[solar trellis]

Create a new C++ class inheriting from UDeveloperSettings, use it in C++.
Make changes under Project Settings in the editor.

[fervent goblet]

Those are not build target specific changes

[winged moss]

This is also why I was mentioning CustomConfig so you can have target-specific config layers, but this requires a source build

A possible alternative which doesn't require a source build is similar to your module idea, but you can enable and disable plugins from a Target.cs

[fervent goblet]

hmmm, I'll test this out a bit tomorrow, too much brainpain for today...

[fervent goblet]

yeah, nothing seems to work without a source built engine (and I don't wish to go there for various reasons). Plugin exclusion wouldn't work either.

Lastly I've tried a custom asset manager, but I can't seem to make any variable in the build target to actually affect the build process (I guess adding a GlobalDefinition doesn't affect the build stage ONLY the packaged build).

I can't understand how something this basic can be this hard? Isn't like every game ever doing this - excluding some assets from demo builds. Or are they doing it manually or with hacky stuff outside the engine?

[winged moss]

The cooker is the editor build

So it uses the editor target

You can pass args to the cooker and UBT in BuildCookRun

But there is a lot of unknowns about your project. It sounds like you have a master table of everything, which definitely makes it harder

[fervent goblet]

it's just a single technology tree table that I'm trying to swap from version to version. A single datatable asset.

Can I affect the args with the build target or should I just give up and run it via command line?

[winged moss]

BuildCookRun via the command line will give you a lot more control

[summer dock]

If you don't really care too much about build size or people scraping assets, you could just have a control boolean IsDemo on/off instead of worrying about what gets packaged ( not saying that isn't wise, just saying there might be an easier way to attack this )

can even pass them in as build args if you want, instead of manually toggling

[fervent goblet]

I have that set up in a global var with the build target, but just wanted to discourage scraping by removing the datatable from the demo build

[summer dock]

yeppa yeppa

[fervent goblet]

I've now settled with chunking it separately and removing it semi manually from the demo build

[torn trout]

There is an issue with Scriptable Tools plugin on UE 5.7. If I try to package with shipping option I get this error: UATHelper: Error: Packaging (Windows): ERROR: Non-editor build cannot depend on non-redistributable modules. C:\Users\PC\Documents\Unreal Projects\Pato\Binaries\Win64\Chapter1-Win64-Shipping.exe depends on 'ToolMenus', 'ToolWidgets'.

I`ve seen forums about this but couldnt find a proper solution for this. Anyone know how to fix this? Thanks

[mystic atlas]

There is no "solution" to this. You aren't allowed to package that module. End of story.

If you want some small functionality that is offered by the module, you could recreate it. Copying stuff from it wholesale is a breach of your EULA.

[rotund breach]

Hi guys
Is there a solution to this problem? I've tried deleting many incorrect files, but this always happens. I also tried it in a new project, but the same thing happens. I always get the same error

[solar trellis]

I was about to call you out on this until you mentioned the EULA and I recall there was a clause there about "editor" features cannot be redistributed without proper per-seat licensing or special licensing from Epic... so yeah, this is actually true.

[solar trellis]

why not add symbols and debug the process? I would start with your blueprint above that is complaining in your error message...

[mystic atlas]

Editor and something else. I forget what the other one is.

[solar trellis]

Movie Sequencer and Architecture stuff, iirc

[mystic atlas]

It's a specific directory.

[zenith idol]

I packaged a UE5.4.4 game on windows 10, anyone who tries to run it on Win10 can launch it without needing anything extra. However Win11 requires this to run it:

Is this normal ?

[gaunt bone]

Yeah, especially if they don't game much.
I know, stuff like steam auto installs stuff like that.

have a see if u can make anything of this

[winged moss]

this is what I would expect if VS was not installed or didn't have the correct components installed

5.6 will require VS2022 with the 14.38 build tools

[wanton sluice]

do u think its worth uninstalling visual studio and doing a fresh install

i have vs2022

no idea about build tools

[winged moss]

not really, but I don't know what VS version or individual components you installed

[wanton sluice]

does the 17.12.4 mean the build tools?

[winged moss]

the IDE is not the build tools

the IDE version doesn't matter much

you install specific build tools versions from individual components, something that is highlighted in the 2nd pinned message of this channel

[unique harbor]

Hey all! I have a packaged game that works on most computers, but on some computers got the "gpu crashed or d3d device removed" error. Saw some sites say that it swapping from dx12 to dx11 helps, but not sure how to set that up to be prompted on launch.

If anyone knows how to do that or has any other suggested fixes I'd really appreciate it!

[solar trellis]

in my experience it is usually a problem with the user's PC, whether drivers, UEFI updates, OS updates, antivirus, anti-malware, etc. Rule those out first.

[lucid ruin]

Having a new issue that I haven't had before where the packaged .exe of my game doesn't open. It kinda just does nothing? From what I can tell there aren't any processes opening in the background of windows errors being logged so any insights would be appreciated

[summer dock]

Show the unreal log

[lucid ruin]

The log of what

[summer dock]

Saved folder

[lucid ruin]

There isn't one

In the build at least

[summer dock]

Make sure you are packaging for development?

[lucid ruin]

I've tried all configs but I can do that again real quick to see if it produces any

[summer dock]

Shipping builds dont have logs

[lucid ruin]

In the past I don't get any logs because nothing opens/it fails before opening

Give me a minute to make another build, should only take a minute or two

[summer dock]

You might also want to scan the packaging log for suspicious warnings

[lucid ruin]

Yeah still no logs

IT almost acts like the exe just isn't doing anything but I'm not sure how that changed from now and a week ago?

[lucid ruin]

Also I barely have any warnings most of them are just misc warnings about input axis errors or pose stuff

[summer dock]

I would do a couple of things

1. one can always sanity check that things are generally ok in the big picture by taking a Blank or Template project, packaging that and verifying it works as expected. This narrows things down to make sure the problem is in your project ( or not )
2. if you are not using version control, start doing so : if the change is related to something in your project ( and it usually is ) then version control helps you trace where things went wrong
3. if you are getting serious, maybe have a small team, set up nightly builds to catch problems faster

[lucid ruin]

Nightly builds is a good idea, just a solo operation for this project but my other gig it's probably a good idea for

[west aurora]

Does anyone know why in my packaged game (UE 5.4.4), all of my actors GUIDs (they are in Streaming Sublevels, NOT instanced streaming levels) are returning as a long 000000000000 string/null? I've set the BP_Class to Cook Property GUIDs and enabled in my proejct settings, but in a packaged build my actors are all returning 00000000 as their GUID value.

[west aurora]

NM, turns out GUIDs are only supported in Editor, awesome news. Time to write my own custom ID tag system

[deep birch]

Hi, I wanted your help regarding creating a mod to increase the length of ziplines so they can be about 500 units long. I tried creating my mod by modifying DefaultZiplineSetting.ini with Retoc, but it doesn’t work—the game doesn’t load my changes. Maybe I’m not using the right function that needs to be modified to get extremely long ziplines.

[mystic atlas]

Is this for some already released game?

If it has a modding community, you should ask there.

[solar trellis]

ini changes are baked and cannot be modified, there are some workarounds but we won't discuss those here, do as the other guy suggested

[deep birch]

Yes it is for the game star rupture and yeah it for a mod

[deep birch]

There no modding community for this particular game

That why i asked in a unreal community cause the problem is not about coding its about packing with unreal packing that im not familar with @solar trellis @mystic atlas

[solar trellis]

this channel is specific for game developers packaging games using Unreal Engine, this channel is not for those creating mods

[deep birch]

Sorry but there no other channel for this particular case

[solar trellis]

I'll be very blunt... there is no one here that can help you, because:

1. They must know (in intimate detail) about game you are talking about and how it was implemented, ask the actual game devs.
2. The game must allow things to be modified, they may not, ask the actual game devs.
3. This discord is for game developers not mod developers.

[deep birch]

Thank for being useless the

[solar trellis]

Yep, I just should not have even tried and just left you unanswered. I'll do that next time and that person can thank you for that.

[mystic atlas]

Unless the developer supports modding, it's not allowed here. And if they did, there would probably be a community for it.

[covert plank]

Hey, I'm running into an issue which chunking. I start to set everything up so it's not file. I tried a Test build and some chunks are missing. In Asset Audit for Editor I can see them, swichting o Window and some are gone.
I defined PrimaryAssetLables and assigned Level files to it. Those level files are not hard referenced in the entire game code.

What went wrong?

[candid coral]

how can you check if an asset is cooked into a build ?

[acoustic plume]

@woven apex

[solar trellis]

you could use the Unreal UnPak method and check what is and isn't there...

[wanton seal]

hii i am back again, can someone explain or send a video on how to fix this problem? i keep getting a turnkey error. Im still not able to do anything because the sdk installation failed

[proven stone]

Well… like it suggests… check the output log since that’s where you’ll find whole turnkey output logs… and those will provide you with specific error

[candid coral]

how do you do this ?

is it a exe tool ? or a console command ? or a console arg to run ?

[proven stone]

UnrealPak.exe is a standalone CLI tool shipped in Engine/Binaries/Win64/UnrealPak.exe you can use it to dump the contents of the pak file, so that way you can use that to check - it's quite a heavy handed aproach, but it would work

[solar trellis]

literally run UnrealPak.exe with the -list command on a .pak file

[solar trellis]

ideally "fool-proof" 😉

[candid coral]

Thanks !

Does this work whatever encryption you use ?

[candid coral]

i tried on my build and i dont have any result

-list doesnt do anything else

[solar trellis]

the rest is on you, we don't encrypt our pak files, we only sign them and use anti-cheat

[candid coral]

ill check the default settings

[candid coral]

so when extracting the .utoc file i managed to have a 9gb folder, where does this come from since my total packaged build is less than 7GB ?

same for ucas file

Does -BuildVersion= work with installed (Launcher) engine builds?

I'm passing -ubtargs="-BuildVersion=3349" to BuildCookRun. The UBT command line in the log shows -BuildVersion=3349 is received, but the packaged monolithic exe still contains the engine version string (++UE5+Release-5.7-CL-...) instead of 3349 when I check FApp::GetBuildVersion().

Is the BuildSettings module recompiled for monolithic game targets on an installed engine, or does it use the precompiled engine version? If not, what's the correct way to stamp a custom build version into a packaged build using the Launcher engine?

[solar trellis]

compression

[solar trellis]

this is something that has always confused me as well, like how to properly version things...

here is all I know.

DefaultGame.ini => ProjectVersion=???

Engine/Build/Build.Version => contains the ++UE5+Release-5.7-CL-... that you are seeing and this is what you would modify as well.

Hopefully someone else has a better answer so I can learn more too...

[stray harness]

This is the best I can deduce...

When Unreal.IsEngineInstalled() is true, all engine modules including BuildSettings get bUsePrecompiled = true. UBT literally skips compilation. The -BuildVersion define change is silently ignored. The .obj from December 2025 (when Epic shipped the 5.7 engine) is linked as-is.
From what I can tell... -BuildVersion simply does not work with installed engine builds. It only works with source engine builds where BuildSettings.cpp actually gets recompiled. The documentation and community advice doesn't comment on this.

[solar trellis]

oh that's their problem! yeah I was wondering about that!

pretty much I assumed most here would be on a source code engine due to dedicated servers and what not

[stray harness]

As an update for anyone looking in the future - I just ended up using a {} replacable bracket set in my AppVersion and manually injecting into the ini during the build process. Would still LOVE to hear how to "properly" do this

Has anyone had this packaging error with nanite enabled? We have to disable nanite otherwise we cant package and we don't know why:

unable to see your file on mobile but search back a good 6-7 months and I asked similar questions about Niagara cooking issues, we have a work around though but could you just show the few lines you are talking about for clarity?

Any time we have Nanite enabled

We can't package the game

So for months now we've just disabled it (but not ideal)

[proven stone]

Seems like you are doing something in materials that fails to produce correct shader code for Nanite related permutations, when I’m at home I’ll check the file you sent previously if I can read more from it… likely what you’ll have to do is enable more shader debugging so we can figure out what’s happening there and/or share the material in question, though it seems like there’s multiple materials that are failing so unless they are all based on one shared master material then it’s some sort of weird issue…. If you are using engine from epic games launcher verify engine files in case some shaders are corrupted or something

[solar trellis]

different than our issue, our issue is that when cooking both client and server targets at the same time it was a race condition as to whether or not the clients would have VFX, we could always cook, so this is something that you guys introduced and need to fix on your side, no one else has your issues

[steady spear]

How does one enable more shader debugging

[proven stone]

https://dev.epicgames.com/documentation/unreal-engine/debugging-the-shader-compile-process-in-unreal-engine

[steady spear]

thank you

[proven stone]

also it seems like the materials that are failing are: M_Landscape, MM_Master_Material_01a, MM_Glass_01a and MM_General at least based on the stuff you've sent, sadly there's not much else I can read out just from the logs... but if you read through the article I've sent above you should be able to get some pointers and hopefully it will help you to track it down

[blazing parrot]

can anyone help me with packaging for windows?

the project isnt cooking

it keeps saaying theres a enhanced input action with a null valua in my bp but there isnt

[solar trellis]

yep there is... you need to set it up as PreDefault module, that's your problem, good luck, it requires an engine change

[blazing parrot]

how would that fix the problem?

is it a known issue?

Im using ue5.7

[solar trellis]

usually when that happens it is because the blueprint is compiling and it can't find the node in the loaded modules in time. but actually it should happen in the editor too, so you likely have something being excluded from cooks or plugins or modules that are not setup properly, so focus on the missing node it is complaining about

[solar trellis]

in older versions yes but we already fixed it in the engine or filed a bug report, I forget, a lot of those are fixed now

[blazing parrot]

ah ok, so the error is this: UATHelper: Error: Cooking (Windows): LogUObjectGlobals: Error: Ignored DoNotCreateDefaultSubobject for Camera as it's marked as required. Creating AlsCameraComponent. EnhancedInputActionEvent references invalid 'null' action for EnhancedInputAction None

[blazing parrot]

its an enhanced input action cant find it for the life of me lol

I only have like one input in my project rn

or in that bp

[blazing parrot]

ok I fixed the issue but now the project just crashes on load

in the built version

[blazing parrot]

these are the logs btw

[spiral sail]

Can someone explain to me how to fix this error? i have tried to resize my page file in my windows performance

[solar trellis]

dumping logs like this into discord requires people to download and open in another viewer, literally 99.99% will not do that, so it is best to chop it down to the actual issue. in addition, this is when you attach the debugger and step through and figure out what's going on

and yes that means I did NOT download it either

[solar trellis]

first of all you need symbols so you can see the complete stacktrace, next like the previous guy you need to debug that process to see what's going on or which asset it is complaining about, debugging the cook process can be tricky but there are some hacks to have it wait for a debugger to attach before it continues

just need the proper command line and I can't be bothered to search for it for you right now... waitfordebugger or something like that

[spiral sail]

Okay. I will research symbols and wait for debugger and try to figure it out. Thank you for responding!

[solar trellis]

I had a bit of time and this website is a goldmine btw:

[placid zealot]

When I package my game in UE5.7 and try to run it, a window pops up telling me it failed to connect to the Zen Storage server.
I can fix it by bringing the Zen Dashboard up and start the server manually or probably also having the editor open, but I would like it to be automatic.

So I installed the zen server as a Windows service with zenserver --install.

I can open up localhost:8558/dashboard in my browser and I see that the DCC for my Project is not listed and also not the DCC for UE5. Only UE4. See first screenshot.

The documentation didn't help me. https://dev.epicgames.com/documentation/unreal-engine/how-to-use-zenserver-streaming-to-play-on-target-in-unreal-engine#enablingzenstreaming

Anyone got an idea? Or have further resources?

[placid zealot]

I now see that the data path for the zenserver is within C:\ProgramData... and when I run it from the dashboard or Editor it's within my user folder.
C:\Users\<User>\AppData\Local\UnrealEngine\Common\Zen\Data.

Tried setting the zenserver service to login as my user instead of the system service and run this: zenserver --install --data-dir C:\Users\<User>\AppData\Local\UnrealEngine\Common\Zen\Data

But it didn't work 😮‍💨

[azure star]

if I think I saw something similar when the <User> had special characters and each time it was trying to launch zen.exe it found the one in AppData

Try deleting/renaming/moving the installation copy you have over at C:\Users\<User>\AppData\Local\UnrealEngine\Common\Zen\Install\

[proven stone]

Pre 5.5 (maybe <= 5.5) things were in programdata and got moved to appdata in the version after… so that disparity is related to UE version (not sure if it’s exposed to config or hardcoded in cpp update: it is exposed to ini in the [Zen.AutoLaunch] section)

Otherwise there should be no compatibility issues and as long as the zen process is running editor should connect to it regardless its location…

Now back to your issue… problem with zen and remote on-device streaming (which is presume is the case you’re trying to run) is that zen is set to localhost only on windows (because http.sys combined with non-localhost binding requiring admin perms on windows)

In ini config you can tell editor to launch zen without limit to loopback…

[Zen.AutoLaunch]
AllowRemoteNetworkService=true

in DefaultEngine.ini should make sure that zen launches without limit to localhost, which will make it so you can use zen streaming on remote devices (like consoles and phones)

and the [Zen.AutoLaunch] section in BaseEngine.ini also has other switches, like whether zen is closed when you exit the owning process, what directory it maps data to and other CLi arguments, so it's worth poking that around

[solar trellis]

Do you guys happen to have some good documentation or links on how to get Zen working?

[proven stone]

Not really, just internet and source code 🙂 … There isn’t much to configure thi, just the autolaunch and the derived data backend graph sections… one to say how the editor will spawn the process and the second just to say that your game will use zen in the first place (zen is enabled by default iirc)

[placid zealot]

Tried setting AllowRemoteNetworkService to true but when I open the editor it complains, because it tries to start the zen server which port is occupied by the zen service.

[proven stone]

That seems like some other zen instance is already running and it’s conflicting… likely trying to spin up new instance since it needs to nit launch with localhost only mode… though I’m speculating right now

[placid zealot]

For now in the ProgramData zen folder I created a "junction" that points to the user zen data folder. That works for now.

[placid zealot]

The Windows Zen server service is running. I want to use that for everything.

[placid zealot]

Also same thing with AllowRemoteNetworkService set to false. Just thought setting it to true might solve it.

[proven stone]

Ah, then you have to disable autolaunch in editor… and I’ve personally never used the service mode as last time I checked it was heavily experimental for desktop use… it was/is intended to be used when the zen instance is used as shared zen

[placid zealot]

Okay. Yeah I think I ditch it for now then. Using the Zen dashboard outside the Editor when I need Zen.

Thanks for the help though 🙏

Ahh nevermind found it. Set AutoLaunch to false in BaseEngine.ini:

[Zen]
AutoLaunch=false

[proven stone]

You can set it even in your defaultEngine.ini but yes, that’s the one… sorry couldn’t send it myself as I’m not at my desk just yet, good thst you found it yourself though

Hi I need help with my ue5.6 project packaging. It cooks some assets and then gets stuck without showing any errors

[solar trellis]

start it manually via script and add -waitfordebugger then attach a debugger and see what happens

[nocturne ember]

could you please elaborate a bit on how to do this?

[winged moss]

create a shortcut in windows explorer and add it to the program target field or run the game from command prompt/terminal with the argument added

[nocturne ember]

I attached it to vs for debugging and the moment where it gets stuck I noticed these lines
The thread 5776 has exited with code 0 (0x0).
The thread 18972 has exited with code 0 (0x0).
The thread 18956 has exited with code 0 (0x0).

The thread 21124 has exited with code 0 (0x0).
The thread 6928 has exited with code 0 (0x0).

[mystic atlas]

That's perfectly normal and happens all the time.

When you say "stuck" describe what you mean.

[nocturne ember]

it doesnt print anything else

[mystic atlas]

For how long?

[nocturne ember]

as long as it keeps running the only thing that does print is

[mystic atlas]

👆

[nocturne ember]

there's no time to it as long as its running

[solar trellis]

then pause it and where is it stuck?

you'll then see what it is working on and you'll have to dig through and evaluate variables

[nocturne ember]

I paused it and i found that it's stuck on this apparently
FShaderCompilingManager::BlockOnShaderMapCompletion()

oh awesome, the Mod removed my ban hammer meme too so I didn't have to 😉

[nocturne ember]

I finally got it to package! not sure what exactly must have helped but i think it was mainly this
I added r.DumpShaderDebugInfo=1 to my ConsoleVariables.ini and during packaging it printed in the output log that my Water material wasnt able to compile because of some UAVs number being exceeded.
Thank you to all who helped!!

you know those are not "compile" logs right?

[solar shard]

Hey, folks. I'm researching how to use Game Features and Modular Gameplay Plugins. The Primary Asset Type Game Feature Data, which is registered by the Game Features plugin on Project Settings > Asset Manager > Primary Asset Types to Scan has an empty Directories list. That led me to believe that any other Primary Asset Types configured the same way would also be automatically scanned across plugins added under /Plugins/GameFeatures. However, my tests showed otherwise. I had to manually add the path of each GFP to every other Primary Asset Type registration (including Primary Asset Label), otherwise the Asset Manager would not detect assets of those types inside the GFP. Am I misunderstanding how asset scanning works for Game Feature Plugins, or is this expected behavior?

[solar trellis]

Good question, no idea, have you looked into Lyra?

[twilit pasture]

Hello guys, I've tried to package the game in development version, but I had this error in VFX

Invalid input type found while attempting initialize new rapid iteration parameters
on
NS_Rain>>WindForce>>Input Name: Module.Physics Field

I've solved it just removing the Wind Force module, but I don't understand the reason why for this error build, cause in Niagara I don't have any errors.
Somebody know the reason why?
Thank you

[solar shard]

Yeah, I just checked, and that confirms it. GameFeatureData seems to be the odd one: it's only registered in the Project Settings and applies globally to all GFPs. All other Primary Asset Types are also registered within each GameFeatureData asset for its respective GFP. So, I guess we have two options: either register the GFP paths in the Project Settings, or re-register the Primary Asset Types inside each GFP.

[solar trellis]

Error or Warning? I think we also saw many warnings like this and Niagara in the engine has been quite a mess for the past few minor versions. We've had to make a bunch of engine changes to get things working properly. You'll likely have to do the same.

And entirely unrelated, a completely different plugin I am working on also fails to build with an entirely different error. Not doing anything weird in this plugin at all, no third party code, just socket stuff. Also not building in a weird way, just the package button in-editor.

[solar trellis]

upon first glance it looks like you are trying to package an editor build or something, look into your Target cs files to make sure they are setup correctly

[meager mural]

Turns out, it wasn't enough to have VS up to date to VS 2022 17.14, I needed to also have build tools updated (modify>individual components tab, search "build tools"). The one I had checked had (Out of Support) appended to it.

[solar trellis]

actually this is also wrong, you must match the version to the engine as defined under Platform SDK in the release notes

[meager mural]

The solution I found is not wrong lol. Literally solved the problem and I was able to package the project. But yes, the build tools and VS version should be whatever works with the Unreal Engine version, in my case it is 5.7.4.

[wanton brook]

hi , dose anyone know why engine still preferd to obj-c rather than swift on apple platform?

thank you guys for this channel

[kindred pollen]

Interesting thing I read about how valve don't want you to pak or encrypt your game data so they can use their own compression for updates etc

wonder what that means for game data protection

[rancid mountain]

@kindred pollen hmm I think you read that wrong

They don't want you to compress your paks

Because they already do compression

But you can also submit without paks

TBH. I was torn about it

Because technically anyone can just unpak easily.

But for my recent demo I chose to pak it

But did not compress it.

Updates are roughly 1.2 GB because of it.

But yeah. I am definitely all ears (eyes) on the best ways to package for Steam

Or in general. We need a full optimization packaging guide

Especially interested in the whole reordering paks business

What else is nice about packaging... Oh I guess we can talk about automation in here as well... Hmm

As far as encryption is concerned... IIRC, players need the key to play. So what's stopping someone from buying and then uploading a hacked version? Giving the key out with it.

[kindred pollen]

mmm

https://answers.unrealengine.com/questions/385942/how-to-encrypt-pak-or-package-file.html

if they fix this I'd want to use pak encryption

@kindred pollen You're always free to use compression or encryption on your game, it just means that updates to your game will basically re-download it.

You can address that issue by using UE4's patching process as much as possible, and resetting patches from time to time by re-doing a large update

The other option is to not compress or encrypt your game

[finite gull]

4.19 has improved pak encryption configuration

[rancid mountain]

@mellow bane patch via frontend?

[open rapids]

O

my

fucking god

thank you for this

IT EXISTS!!!

#packaging exists boys

@finite gull Is pak encryption even that useful thoungh

The pak file itself is simply a binary file right

Are there extractors people have made lol

[rancid mountain]

Well

The point of encryption is so they can't without the key

But....there are decrypters

[open rapids]

yea

i mean it depends

what encryption standard is it using?

it it like one of the AES standards

[rancid mountain]

No idea haven't looked into it

[open rapids]

like if its some

base64 shit

thats useless lol

[rancid mountain]

I don't get how useful it would be really in regular games anyway

[mellow bane]

@rancid mountain Yeah.

[rancid mountain]

Again. The player needs the key to do anything

So it's pretty much DRM

From the 90s

[mellow bane]

BTW, zero client-side encryption can ever work

Not reliably

Not on a PC anyway.

[rancid mountain]

Aye

[open rapids]

u know whats funnyt

u can just get the password from memory

if its on client side

Lol

[rancid mountain]

Not entirely too sure what's up with the new options. Guess we will have to play around with them. Maybe wrong.

[mellow bane]

I'm happy that this channel exist, we took quite some time to refine our packaging process ourselves. Props to the awesome Roy

[rancid mountain]

@mellow bane you have any links to any wikis or blogs that helped?

Or planning on creating one?

TBH. That's the one thing epic really forgets to talk about. The end game of things.

Always the beginning and middle. But the end... GL

[mellow bane]

@rancid mountain This doc worked well for us : https://docs.unrealengine.com/latest/INT/Engine/Deployment/Patching/

[rancid mountain]

@mellow bane aye. Seen that one

[mellow bane]

We used releases + patches initially, when we were shipping our game with a custom launcher in private beta.

[rancid mountain]

I am just wondering about little known tips and tricks

[mellow bane]

We moved on to a much simpler system once we had access to Steam

[rancid mountain]

Like how to actually decrease file size.

Down to a sliver

Which @ocean rune figured out after some trial and error

But those were jam entries

[mellow bane]

The way we package our game right now makes it way larger than it has to be, so I won't be of any help there

[rancid mountain]

Aye. Do you pay?

Pak

[mellow bane]

We don't.

uh

We do

Uncompressed paks, though

[rancid mountain]

Just wondering the best way for patching

Yea

I men right now. The demo players are getting 1.2GB patches

From a 7GB initial install.

[mellow bane]

The biggest question you should be asking is what your distribution platform wants

[rancid mountain]

I feel like 1.3GB for the little changes...is too much

[mellow bane]

When using Steam, the key to small downloads is to disable compression & encryption of paks

[rancid mountain]

Yeah

Which got us down to 1.2 GB... Lol

But seriously... These small BP changes are not worth 1.2GB...so trying to figure out what else it could be.

[mellow bane]

In my experience, Steam is really good at doing the diff. Like, it is actually better than UE4's compression, which is kind of impressive, considering it doesn't know what's in the files.

Do you have static lighting ?

That's one way to get a gigabyte patch from moving a barrel

(One that's 100% guaranteed and unfixable)

[rancid mountain]

Stationary

So yeah we build lighting

[mellow bane]

If you want to be sure that you really have actual new data, you can try doing a UE4 patch using the doc above

If it's 1.2Gb, then yeah, chances are, you have no way to reduce it

[rancid mountain]

Hmmmmmmm. Boo

[mellow bane]

I mean, try Steam and the UE4 patcher

[rancid mountain]

Yeah I will look into more

Because this is just the demo

The game itself will be 10x or more bigger

[mellow bane]

Both UE4 and Steam use different methods for patching, so if they both do GB range, it means you really have a GB worth of new information

[rancid mountain]

Ah

[mellow bane]

Lighting isn't deterministic, so building twice will always do a giant diff, no matter how changed the lighting really is

Real solutions for this are smaller lightmap resolutions, more & smaller levels

Is your game 7GB with uncompressed or compressed paks ?

If you need compression on the client, you need the UE4 patching system. Steam will be unable to create a decent patch.

[finite gull]

Every patch isn't going to include lighting changes tho

[rancid mountain]

Exactly

And I don't rebuild everytime I patch

7GB uncompressed

It was 3.5GB compressed

[mellow bane]

@rancid mountain Basically, the two options I see are "no compression on client, Steam does the patching" and "compression on client, UE4 does the patching"

For PC, I mean. I don't know about consoles, but I suspect the second option would be required

[rancid mountain]

Hm

[mellow bane]

Updates will have similar sizes

[rancid mountain]

I do plan on taking this to PSVR later after release

So going to need to make sure I do make it as small as possible

[mellow bane]

I don't now anything about the PS4, but Steam's automatic diff is pretty great (it's Perforce, btw)

I wouldn't be surprised if a console had a simpler patch-based approach

In any case, the cleanest way is probably the UE4 way - it's also the most annoying.

[open rapids]

@rancid mountain https://i.imgur.com/jJYYmt3.png

i find it funny lol

how i searched #discord on twitter

and saw u

[mellow bane]

@rancid mountain BTW, we found building the game to be more annoying that patching.

Getting an UAT command line to work reliably on Windows & Linux is pretty painful

[rancid mountain]

@mellow bane Hmm, interesting. The only issues packaging I've had that I can't resolve yet are BP Nativitization

But usually, I can figure out what's wrong and package, unless you aren't talking about Packaging Errors via UAT

[mellow bane]

@rancid mountain Issues we had were mostly about not rebuilding the entire engine, including localization, etc

We ended up with a nice Python script that takes a JSON config

[versed musk]

hey guys, I hope I'm at the right channel 😃 I ran into the following problem, when trying to open a project I get this "... is unversioned and we cannot safely load unversioned files in the editor" ... I tried to search for this exact problem but I found nothing. I found UModel, which was able to load in the assets with the version I'm using but UE Editor couldnt... 😐 any tips?

[dusky rampart]

You're probably trying to load assets saved in a newer version of the engine than the one you're using

@versed musk

[versed musk]

@dusky rampart im pretty sure its saved in 4.18.x and im using 4.18.3 myself... i was able to open some assets in it UModel forcing 4.18 as well. Is there a way to query the version exactly?

[dusky rampart]

I don't think so, where did you get the assets from?

[versed musk]

Friend collab starting proj ... message didnt reach him yet

Tested some other files and saw that ue4 versions are in the header of an uasset file. In his they are missing. On phone, but will upload a simple test later. It's just a cube but I still get this in the output log :(

[dusky rampart]

it could be that the project he created his in has a different name that's referenced somewhere else. I would stay away from this kind of workflow and create a source control server, there are documents on it

[strange elm]

My C++/BP hybrid game won't build on either of two machines I have tried to package it on

This is the error I get

LINK : fatal error LNK1181: cannot open input file 'C:\Program Files\Epic Games\UE_4.16\Engine\Binaries\Win64\UE4-UMGEditor.lib'

I am using UMG in my C++, creating widgets in a custom PlayerController class

I am wondering if this is relevant

[rancid mountain]

@strange elm Now, this may suck. And not sure exactly what causes this. You can try a few things before you do it. #1 Make sure you are running 100% administrator mode on your account

Try this : https://www.ghacks.net/2014/11/12/how-to-enable-the-hidden-windows-10-administrator-account/

Right click on your install and project

And make sure that your user has all permissions

Failing all that

Reinstall the version on a separate drive away from C:

Now, this is sort of extreme, but only way that I could get damn games to package was to move them away from C: drive

Windows 10 was too op for me

[strange elm]

interersting

I don't have full permissions

with my version

[rancid mountain]

😃

Yeah...so

That's probably what's going on

[strange elm]

I have read & execute

list folder contents

and read

[rancid mountain]

Not sure why or how it happens

I just gave up

I rather just install it on another drive and never have to worry about it again

Also, only happens with UE4

other programs are just fine

[strange elm]

so I need to give myself permissions to do more with UE4?

[rancid mountain]

¯_(ツ)_/¯

@strange elm Yes

Or just install it on another drive

And just be happy

[strange elm]

Install Unreal on another drive?

[rancid mountain]

Right

uninstall it from c:

install on D; or whatever

I have a whole drive dedicated to ue4 now

[strange elm]

and what does that achieve?

[rancid mountain]

¯_(ツ)_/¯

[strange elm]

I'm not asking to be difficult I'm genuinely curious

oh welp

[rancid mountain]

You tell me when you do it

[slender solstice]

FWIW, I don't have that library in the launcher build of my engine either

[strange elm]

yo that's weird

it's looking for a file that isn't even there

[slender solstice]

It might be some sort of dependency issue

[strange elm]

I have

UE4-UMG.lib

and I have

[slender solstice]

Have you seen this page?

https://answers.unrealengine.com/questions/662462/userwidget-visual-studio-error-c1083-cannot-open-i.html?sort=oldest

[strange elm]

I haven't but thank you so much

[slender solstice]

Looks like you might be adding a UMGEditor dependency where you shouldn't be

[strange elm]

OHHHHHHHHHHHHHH

wait

I don't have UMGEditor

here's my build file

{
    public StrategyGame2(ReadOnlyTargetRules Target) : base(Target)
    {
        PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
    
        PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore" });

        PrivateDependencyModuleNames.AddRange(new string[] {  });

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

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

Only UMG, not UMGEditor

should I remove UMG?

[slender solstice]

If you're actually depending on it, no

[strange elm]

I am

I make use of functions like CreateWidget and stuff

in a class

[slender solstice]

Hmm, that's pretty odd then

Maybe look in your .uproject? I'm seeing some posts online saying there's an AdditionalDependencies field in there

[strange elm]

How does one look in their uproject?

[slender solstice]

Open it with any text editor

It's just a json file

[strange elm]

you mean the project file by uproject?

the executable?

[slender solstice]

No, the one that ends in .uproject

It won't be in your packaged game, it's in the project directory

[strange elm]

OH

OH YOU MEAN

in the solution explorer?

[slender solstice]

Uh

Well, I guess it might be there?

https://i.imgur.com/uXDZzb8.png

[strange elm]

oh yeah that's what I thought you meant

[strange elm]

I can open that?

[slender solstice]

Right click, open with

[slender solstice]

See any UMGEditor in there?

[slender solstice]

Ah, there you go 😃

Try to remove that line and rebuild, see if that helps

I wonder how that ended up there, haha

[strange elm]

welp it builds

now to see if it packages

it packaged

thank you so much

UATHelper: Packaging (Android (ETC1)):  [proguard] Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [classes.jar:META-INF/MANIFEST.MF])

I have added a "ManifestRequirementsOverride.txt" to Project/Build/Android.

[hallow veldt]

No one? 🙁
I cant get either ads or play services to work. I'm pretty sure its because of this stuff

I have tried adding a ManifestRequirementsOverride.txt file to remove all the permissions I don't need. It didnt make a difference

I have asked in the Facebook group, UE4 forum and the answer hub but nobody is responding 😂

Everything from AdMob, Firebase and the Google Console have been linked to UE4. I have generated a keystore as well.

The AdMob page says I have several ads requested, but no ad views.

The Google Play login thing appears when I use the "Show External Login UI" node, but it dissapears before letting me sign in.

[light junco]

@open rapids i do not get why gamesparks or steam is important in the packaging channel

Isn't that more a #multiplayer thing?

[onyx berry]

i'm having an issue with my packaged game. everything runs fine in the editor and i even packaged the shooter game and that works but when i package my game and run the exe nothing happens, how can i find out whats going on?

[light junco]

Check the logs

[onyx berry]

i don't see any logs folder, one was generated for the shooter game though don't know why mine doesn't have it

[hollow finch]

im trying to launch my game via standalone but it keeps crashing, i was wondering if someone can take a look at my directory to see whats wrong

[light junco]

So, I'm a bit struggling with understanding how Mobile defines Patching

The official docs are mostly talking about the "initial pak" file and the rest of the content.
That all works fine and the BP nodes (despite the disk size pre 4.18) work quite well

Now this uses DLCs

But a DLC is not a patch

Do I now use DLCs for Patching Mobile or a Patch?

As both options exist in the packaging settings of unreal frontend

[light junco]

Okay so for Patching the original release, I assume regenerating the whole file and uploading that under a higher versionnumber to the store should already take care of that

Idk how the stores handle that, if they do file checks, if it's work not uploading it as one pak file but rather as loose files.

Now the DLC files patching is another story I assume

Can you even create a PATCH for DLC?

It makes 0 sense to me why not

If the APK is 40MB and downloads the DLC1.0 for the additional content. Let's say it's a massive game with 1 GB of content.
If I now add 10MB of new content, I wouldn't want to redownload the whole DLC1.0.

And since DLCs are based on whole Maps instead of file differences, creating DLC2.0 or DLC1.1 anew, would still result in 1.01 GB

What are you supposed to select in the packaging settings for that :/

Patches require a Release Version and building a DLC doesn't let you create a Release Version

[light junco]

Okay, it seems like the whole DLC Patching works by just creating the DLC again with the old folders and files still in place

Then packaging the DLC again with the changes and override the files on the webspace

After that it downloaded only 2MB instead of the initially 9MB

Guess that works?

[earnest elbow]

Bros

How to package only one level?

Dont know how to set Custom Launch Profiles properly

He said client target not found,but where to set client target?

[winged moss]

well i can't read most of that and you cropped out the UAT commandline arguments, but if you're building the "Client" target you'll need a <Project Name>Client.Target.cs file

"Client" as opposed to a normal game target strips out the server side code

eg. UWorld::Listen is no-op'd

[hard goblet]

When I package my game, overlaps are no longer detected but in the editor when I play, they are

What might be causing this?

[light junco]

Maybe collision settings resetting or so :/ do you have custom collision types and channels

[weary steeple]

@hard goblet I've had similar issue in ~4.15, the solution was to set Collision\Overlap parameters in blueprints

[hard goblet]

@weary steeple @light junco It ended up being a bug. If you create Blueprint out of a TextRender and create a trigger box inside of it but parent it to the SpriteComponent instead of the root (TextRender), the box will not detect overlaps in a packaged build (Engine 4.16.3). Re-parenting the trigger box to the root and packaging let me detect overlaps as intended. I submitted it as a bug report!

It may not be a bug but it's not something I was able to read about anywhere.

[weary steeple]

Glad you figured it out

How can I tell what is the offending asset?

I suspect it might be something to do with these things as well :

my HLOD's maybe got cooked poorly and now the black ones are causing problems

Are you trying to package an game that has Blueprint compilation errors?

Make sure your Game can run in PIE before attempting an package

Theres your Ensure thats causing the issue.

@frank garnet That github link won't open for me

You need to be registered and have your account linked so that Epic can give you permission to access their GitHub repo.

[quick kayak]

Ah

And yeah, the game has been running fine in the editor

I've got to get to sleep, I'll check in tomorrow when people are awake

So looking into it with a clear mind thismorning it doesn't seem to be the ensure that's causing the failure, because it throws that error a few times during the cook. Still an issue that needs to be fixed, but it's probably something else

UATHelper: Packaging (Windows (32-bit)): LogOutputDevice: Error: Container has changed during ranged-for iteration!

that seems to be the relavent bit

editor will survive when that happens, but odds are it will freeze for a while

[fallen rivet]

well what can cause it?

[hasty rover]

you adding or removing items from an array you are doing ranged-for loop on at the time

[fallen rivet]

ah

ty for translating it :p

[hasty rover]

it could be TMap or TSet

doesn't have to be TArray

it just usually is

[fallen rivet]

ah

i did use to have a auto spam filling array for list of teams

but i think that one did not rrefresh untill both teams was full

is there a way to find out which array it would be

[coarse berry]

can anyone think of a reason why Mac isn't an option in this list?

even though Mac is selected here:

[open rapids]

afaik You can only export for mac from a Mac Device

or create a virtual machine

[coarse berry]

ahh

rip

actually

[mellow bane]

Yeah

[coarse berry]

no I've got a mac

oh hey stranger!

you'd probably be happy to know I got multiplayer working in my game 😛

[mellow bane]

Yeah, happy to know 😉

We gave up on Mac ourselves, it's not like the hardware is gaming oriented anyway

[coarse berry]

yeah I guess

doesn't Metal help though?

[mellow bane]

Metal doesn't make an Intel mobile GPU render UE4 games at huge resolutions

[coarse berry]

the game I'm trying to port to mac is 2D with paper sprites

[mellow bane]

2D could work

[coarse berry]

it runs at 40fps on my surface pro 4 (i5, 4gb ram)

[near falcon]

Not sure if this is the right place, but is it possible to tell an asset (preferably textures and models) to stay in memory the whole time?
For example the Main Character's Model and related assets should stay in memory

Anyone recognize any of these errors I'm getting in my UE4 Win64 Packaging? https://pastebin.com/wDfqu05P

Here's the full UAT_Log.txt https://answers.unrealengine.com/storage/temp/228574-uat-log.txt

I've been trying to figure it out for 4 days and I've come up with nothing

It seems to throw this error in any project that has C++ classes in it, are there any default troublehsooting steps I could do to fix my visual studio 2017?

I also notice that the packager is packing up tutorial files and things like that, which I have disabled. Maybe I disabled them wrong though, any input on that?>

[compact cobalt]

is there any way to launch custom profile from cmd?

not from editor?

[finite gull]

Anyone know how to change this name?

[thorny ember]

I think that's your project name

E.g. yourname.uproject

[finite gull]

There is ProjectName in DefaultGame.ini but that's set to Omniwar. I assume changing the uproject name is going to break things.

[thorny ember]

Not neccessarily

I think you only need to change the uproject filename, change yourname.Target.cs and its contents

And maybe rename the main game module, but I think that's no longer neccessary

[finite gull]

okay, I'll mess around with it. thank you

Doesn't mean the bug doesn't affect 4.17. Normally just means that is the version it was discovered in. Anyways I don't use blueprint nativization.

[errant gate]

Hey guys! I have a problem here. I am making a project for PC and it is working just fine there, but recently I desided to make it available for Mac as well. So on my Mac UE4 editor works fine along with my project, but when I package it, it just won't start. In fact the game icon appears and the process seems to be running, but with no image whatsoever (not a black screen, but just desktop as if the game was minimized). After waiting for about 20 minutes nothing happens. I tried packaging an empty project, and although it took it like 2 minutes to start, it worked fine. So does anyone know if there are some "special" ways you have to treat the project to be able to run it on mac?

[lone moth]

Okey guys so I have a problem

Ttesting a game in pre Alpha.

After some initial difficulties I got the game t run and thought it was working fine (considering the alpha stage).

Well it seems taht the map I played in was comlpetely finished, where as I only saw partial textures and partial hard surfaces of the level (I had plenty of invisible walls etc).

Will post a screenshot of this

The map used for the mainmenu worked fine heres a working main menu:

I tried reinstalling the game in another folder to see if it was installation related

In that install, the bug is even worse. The bug affects menu too and in the actual level Im not only missing the ground texture, but also the concrete mesh (I can see and shoot through the ground). Everyone I see runnign are constantly droppping through the ground since there is no ground, even though they are working fine on their own ends

Heres a screenshot of the menu with the bug taking place.

Anyone @here have any idea what might cause this?

And unlike other players in the server, I actually am able to shoot through walls with that bug.

The bugs are rooted in the installdirectories (one directory has "milder" version of the bug, where as the other one has the version where even main menu doesnt work).

Heres also the same view in the install which bugs the most (where the menu desnt work)

Basically the map you see in 3rd person view should be equally populated and detailed as the workign main menu (and is for other testers).

[frank garnet]

Thats crazy weird. I remember seeing something similar an long time ago someone reported it in like 4.2 but i cant remember for the life of me what the actual issue was 😦

[lone moth]

Tried googling for it, but for once they keywords to use are at loss to me

Hmm, the different installs have different pak files

[ocean rune]

as totally another topic

I had issues with packaged 4.18.3 builds

game just freezed on some people on development build

and shipping build just gave "fatal error" on launch

turned out that enabling UDP and TCP messaging -plugins fixed both dev build freezing and shipping builds fatal error

this took me many days to figure out as I didn't pay attention to the shipping build issue before

and tried to find the fault on the freezing issue from my own code as I only recently upgraded that project into 4.18

[errant gate]

@ocean rune I am familiar with that one. There is even a post on AnswerHub, but no replies from devs whatsoever.

[finite gull]

My custom icon won't show up in the windows taskbar when I run my game. But it shows up in file explorer. It works fine when I create a new project and use the same icon, so it's not the ico file. Anyone have experience with this?

[finite gull]

It's just showing the generic unreal icon on the taskbar with my project

[plucky bronze]

I couldn't even package without UDP/TCP messaging in previous versions, don't even know what exactly it does

[ocean rune]

calls home to epic :p

well, it used to spam the windows firewall about wanting internet access if those were enabled

so I got used to disabling them on non multiplayer games as it's never a good sign that single player game wants to go to internet

[onyx berry]

Is there a way to not include unused content in the packaged build? can't seem to find an answer googling it

[sterile pier]

By default it shouldn't. But I think it needs to be not referenced by anything in any of your levels in order for a content to be considered unused.

[onyx berry]

i added the starter content and am using a particle effect, now my packaged game went from 300mb to 700

[wind fiber]

do you still have the extra map that comes with the starter content?

that could be causing it since assets referenced by any map in the project are packaged

[onyx berry]

ah yea the map is still there

i'll remove it and try again

[wind fiber]

did it work?

[onyx berry]

building now computer is slow

nope still 700mb

i'll delete all the starter content just to make sure its not something else

the content *.pak is 500 mb

all my content is 30 mb

[wind fiber]

interesting

[onyx berry]

rebuilding after removing the starter content is back to 300mb

[storm hatch]

so, I am packaging up the project and im getting this error
UATHelper: Packaging (Windows (64-bit)): C:\Users\minec\Desktop\Apocalypse\Apocalypse\Source\Apocalypse\Door.cpp(6): error C3861: 'SetPivotOffset': identifier not found

but this doesnt happen when compiling

so.... not sure what thats all about, iuts causing the packaging tool to stop and give man an unkown error

[frank garnet]

Why is your project on the Desktop? Thats an really silly place to have it lol.

In relation to your Error, can you post the entire log?

It maybe an issue further up

But you should definately make sure that your compiling correctly.

UAT doesnt report errors in code for no reason lol

[storm hatch]

https://hastebin.com/otohijoluq.tex

[frank garnet]

Ok well its definately an compilation error.

Recompile?

Make sure you didnt miss it.

[storm hatch]

I keep my project on desktop for ease of access someone has asked me the same before and said it was a bad idea, if you'd like after I fix the error maybe you can talk some sense into me

[frank garnet]

Can you post the Code for Door.cpp?

[storm hatch]

hold up im getting this warning when compiling Warning: Starting HotReload took 0.0s.

[frank garnet]

Close your editor and recompile from VS

[storm hatch]

ok recompiling from vs now

https://hastebin.com/okoqarabaq.cpp

thats the code

it doesnt actually work, and it was really poorly designed so maybe I should just delete it

also I recompiled from vs just fine

[frank garnet]

If your not using it just delete it?

Dont forget to Generate your Solution file again

[sterile pier]

AInteractable::SetPivotOffset() might only be declared for the editor?

[storm hatch]

oh, you know what maybe so

[sterile pier]

in that case, something like this should fix it

    bReplicates = true;
#if WITH_EDITOR
    SetPivotOffset(FVector(100, 0, 0));
#endif
}```

[storm hatch]

is that functioning code?

[frank garnet]

Yes its just an Preprocessor which stripes out the code in that block if it ISNT an Editor build

[storm hatch]

ok, I just dont have much experience with preprocessrors in unreal

ok so while this trys to repackage, tell me whats wrong with putting my project on the desktop please

[frank garnet]

An couple of things

There is an DirectoryPathLengthLimit

You want your Projects to be as close to the begining of the drive as possible

For example i have an single drive for my UE4

D:/Projects/....

Secondly the Desktop just like the MyDocs folder has weird ass permission requirements which can mess with shit

[ionic briar]

I'm trying to package my project and I'm getting a ton (more than 50, so I can't see them all) of these:
UATHelper: Packaging (Windows (64-bit)): Cook: LogInit: Display: CookResults: Error: Error loading D:/Unfinished Business/GGJ-2018/UnfinishedBusiness/Content/SoulCity/Environment/Textures/Water/T_Soul_Water01_N.uasset!

The Content/SoulCity folder was deleted long ago, so none of those files exist.

I've tried to Fix Up Redirectors, but it doesn't seem to do anything.

[storm hatch]

so when building a "shipping server" build after packagaing it says it cant find lots of files

and this only happens for the dedicated server

the actual game itself works perfectly

[storm hatch]

I can't for the life of me figure this out and its already pushing me behind schedule, so if any could help that would be amazing

[storm hatch]

I also get this box after clciking ok on that one ^

[still quiver]

Anyone have experience with HTML5? On 4.18.3 my project just sits at "Launching Engine..." no errors or anything...

[sterile pier]

@storm hatch Shipping exes can't be run from the debugger unless you run it from the correct place in the packaged folder. So you can copy the exe to your pacakge's Binaries/Win64, start running it from there, and then attach the debugger.

[storm hatch]

well its no longerr neccesary, but thank you anyhow

[restive pewter]

hi everyone

wondering.. is there a tool that let you package the game outside of editor

by just providing Profile name formProject Launcher

[hot totem]

Hello!

I was thinking if it's possible to win some space on the disk with some specific lightmap optimization (package method, delete some useful things...). Someone has some ideas about that?

[frank garnet]

@restive pewter You can invoke UAT yourself in CommandPrompt. My Build Server runs an instance of Jenkins with an big build script that invokes UBT to compile the project then runs UAT to package it before it compresses and uploads it to an FTP server for distribution.

[open rapids]

hello guys, I've been pulling my hairs out for the last few hours on a problem I can't solve. When I pack the project which runs fine in the editor I got the following errors
Error: Ensure condition failed: ChildActorTemplate == nullptr
Error: Found unexpected ChildActorTemplate LinkerPlaceholderExportObject

The error is on a Child Actor Component to which I have a child class actor

as long as I don't call the child component everything is fine, but if I try an operation like a "get" on it I have this error

I've found on the net that the "Editable when inherited" should be uncheck which I did but to no avail

I'm short on idea and I've tried a few solution on the net but nothing seems to work and I have no real work around 😦

any help would be greatly appreciated thank you

[near falcon]

Does UE only compile/package what's necessary/used or does it compile everything in regards of Plugins, Function Libraries etc?
For example when I have a plugin which has lots of Actors, but I only use one Actor of it, will it package all other actors,too?
What about Function Libraries? Are all functions packaged or only functions I am actually using?

[frank garnet]

It attempts to cook out anything you arent using.

[glossy haven]

has anyone had any problems w/ foliage culling getting messed up in packaged builds?

I've raised an issue on answerhub about this, someone from epic even came up with some advice (that didn't work unfortunately) but it's kind of hard to believe no one else is coming across this

it's very easy to reproduce in vanilla ue4

...and it works perfectly fine in PIE and the editor

[still quiver]

Trying to figure out this issue with my HTML5 build, anyone? The game will download in the browser and web assembly will work. It'll sit at loading engine but in the browser console this comes up:

Source map information is not available, emscripten_log with EM_LOG_C_STACK will be ignored. Build with "--pre-js $EMSCRIPTEN/src/emscripten-source-map.min.js" linker flag to add source map loading to code.

I may have figured it out...

[still quiver]

So I found out I need to make a few changes to the HTML5ToolChain.cs (remove the comment out on source map).

However, even after a recompile it does not seem to be utilizing the new code, any thoughts? I can't tell if the UnrealBuildTool is not updating it properly or if it still doesnt work even with this new code.

Opening up emscripten-source-map.min.js, it shows it outputs some text to the log file, which doesnt show up in my log. Trying a clean/build on source and project and see if that does it.

[restive pewter]

@frank garnet thanks... that would be useful

[still quiver]

How do i enable a linker flag? I've made some changes in HTML5ToolChain.cs, recompiled, ran a full rebuild on the game but I still get the same issue

[tacit mason]

Hey guys, sorry to interrupt, but when I try and package my game, I'm getting these errors. This seems to be connected to the engine itself somehow? Have you had anything like this come up before?

[ocean rune]

most odd packaging errors I've got has been related to me disabling some plugin that UE4 depends on

[tacit mason]

Allright so I fixed it, turns out one of the animators had added unnessecary curves to an animation, and unreal really didn't like that. But all fixed now!

[grizzled ridge]

What do I do about an Unknown Cook Error? I don't see any other errors in the logs that I could use to figure out where the packaging process failed.

[frank garnet]

There will be an error in your packaging log, use an search all to find it.

[grizzled ridge]

which log is that? Which directory can I find it at?

[frank garnet]

Its literally in the Output Log

If you packaged from within the editor which im assuming you did

[grizzled ridge]

Yes, but there are no other errors in there other than unknown Cook Error

I cleared the logs before packaging, and it doesn't generate much in the way logs during the packaging process. It's a very short log, and the only error there is the unknown cook error.

[frank garnet]

Put your log into pastebin

[grizzled ridge]

https://pastebin.com/TaJgsTdd

[frank garnet]

Mmm ok well since your on Linux im not going to be able to help you woth that.

#linux May yield better results

[grizzled ridge]

You're not familiar with any other places I could get logging of where the packaging is breaking?

That should be platform-independent.

[frank garnet]

Saved folder is your best bet

[grizzled ridge]

Thanks for your help. I'll give it a look.

[frank garnet]

Good luck

[grizzled ridge]

wait, project Saved folder or engine Saved foler?

actually, that might only be project, never mind

[astral mortar]

How can i make a auto updater for my patch files?

[ocean rune]

most distributing platforms have such

[marble goblet]

can anyone package the third person template project less than 60mb

I ve compressed and excluded all the plugins and content I can ,and the package is around 70mb, any way to make the package even smaller?

[ocean rune]

you need to blacklist unused assets

also do note that default skysphere textures are pretty big if you want shave of the package size

if you don't need starry night sky, you can remove the star texture from it etc

also

32 bit builds are tad smaller

and shipping conf of course

@marble goblet

I'll requote my first post on this channel

[marble goblet]

thx I see the sky sphere is very big actually

[ocean rune]

"https://docs.unrealengine.com/latest/INT/Engine/Performance/ReducingPackageSize/index.html , path for blacklist on windows is <project folder>/Build/Win64/PakBlacklist-Shipping.txt (or Win32 / PakBlacklist-Development.txt etc)"

to see what actually gets packaged, you have to disable packing to pak so you can see what files got into Saved folder

once you get them blacklisted, you can put the pak + compression back on

[marble goblet]

Its around 50mb now👍🏽

[ocean rune]

oh, is this mobile?

I don't have any mobile tips tho, just curious

[marble goblet]

no just prepare for today’s gamejam

there is a special category which requires projects under 100mb

[ocean rune]

UE4 jam?

some other?

[marble goblet]

yes the winter jam

[ocean rune]

oh crap, I'm helping my competition then 😄

[marble goblet]

3 hrs til the theme anouncement

hhahaha

good luck lol

[ocean rune]

last time they had this category on megajam, I got template down to 30mb

but I didn't actually finish the game

[marble goblet]

Is that a 2D game?

[ocean rune]

but 50 mb is still plenty room for gamejam

nah, it was fully functional UE4

3D stuff, just no assets

[marble goblet]

Sometimes even lowpoly style takes more than 100mb

[ocean rune]

I had a pretty fancy asset loading setup but there's no way I could make it in a weekend jam

I aimed in having everything hq

nothing low poly 😄

[marble goblet]

yeah we did a huge one on last years megajam

and ends up quite unfinished too

[ocean rune]

I always solo

and I always get sidetracked on doing tech

so I usually don't finish at all

but it's ok, it would lose all the fun if one panic too much on small details, like finishing it 😄

@fierce garnet you should try to clear the warnings before, like "CH Enemy does not inherit from CH Generic", it could be the symptoms of more important issues

Initially I was using the github version of unreal, I tried to generate DLC in the official 4.18.3 version and its not working as well. Anyone can with this problem?

Hey guys, got no answer posting this the other day so posting again:

UATHelper: Packaging (Windows (64-bit)): LogInit: Display: LogShaderCompilers: Warning: X:\FF-Git\Content\FF_GARAGE\Meshes\materials\lambert2.uasset: Failed to compile Material for platform GLSL_150, Default Material will be used in game.

How can I find out why some materials are failing to compile? This is all the output log is giving me and the material editor doesn't show any problems

ProcessResult.StdOut: LINK : fatal error LNK1181: cannot open input file 'libfbxsdk-md.lib'

what?

I get that in the end of building distributable

as in packaging

and I have zero idea what that's about

what the fuuuu

okay so I read that this might be because I have UnrealEd as a private module dependency 🤔

but if I remove it my c++ stuff breaks down completely

Hello everyone!
Can't build the game for IOS.
engine version 4.18 ( version 4.17 works well)
mac OS 10.13.3
I'm using a template from a ThridPerson blueprint.

please help
Thanks

The engine is build in Xcode 8.3 and Xcode 9.2, same error

Build the project under MacOS passes without error

is higher cpu frequency and single thread performance more important than core count for cooking and compressing? takes about 3-4 hours to cook and compress 29gb down to 14.9gb with 22 vCPU's @ 2.30ghz

[sterile pier]

generally speaking, higher clock, single thread performance, and I/O performance.

SSDs are a must, and since you mention vCPUs, running in a VM you'll probably take a pretty big hit.

M.2s FTW 😃

thanks for the info, i was thinking virtualization was probably a big part of the problem too

any server providers you'd recommend that have high performance CPU's and NVME storage support?
