Something like this in your config?

[paper raptor]

i think i remember this line

yeah let me check

[fast ingot]

did you try packaging yet btw

[paper raptor]

yup i did

still the same error

[paper raptor]

this is in the DefaultEngine.ini?

[fast ingot]

yea

[paper raptor]

cant seem to find this line

tried to use find text

doesnt exist

[fast ingot]

ok... cuz there is no straight up "GameName" entry anywhere

[paper raptor]

besides the one i added

[fast ingot]

that seems like it must be networking related or something

never used this myself

[paper raptor]

how so?

[fast ingot]

try taking that line out honestly

the tutorial you are using is from 2015

[paper raptor]

yeah lol

alright 1 sec

[fast ingot]

never seen this shit :P

[paper raptor]

alright deleted it

trying now

oof still doenst work

[fast ingot]

[paper raptor]

it seems to be a problem with the "BuildTarget=UE4Game" being automatically added

I am doomed

[fast ingot]

I mean, that ue4game module is supposed to exist in the ue4 engine binaries folder

but it's like it's looking in the wrong place or somethin

[paper raptor]

yea i guess

im thinking of a few fixes

like setting the GameEngine file to read only

so it doesnt keep changing the build target

[split flare]

Trying to avoid spam, but this might be a more relevant channel than #umg

Has anyone ever had issues with Images for a Rich Text Block Image Decorator not appearing in Packaged builds? The uassets for the images+decorator are in the packaged build, but when the level loads the Rich Text Block doesn't actually render the inline images.

It sounds like an Asset Loading issue but I can't quite pin down why the Images aren't loaded with the level if everything from Level->Widget->Decorator->ImageSet->Image are hard references.

[craggy cobalt]

should work

definitely this channel is ideal for that

the UI that contains the richtext though, how does it get loaded?

actually never mind I get it, it's all hard refs

so I assume that's Create Widget with a direct reference right on the pin

can you check the cook log and see if there's an entry for it?

and also look for any relevant warnings and fix them, even if they are maybe only tangentially relevant

I am using an image decorator but for me it's using dynamically loaded primary assets and not the regular structure that the built in richtextimagedecorator is using

only problem I ran into was ensuring "Allow engine to determine name and type" was needed to use texture as primary assets

if your just using the regular decorator it should be easier

[split flare]

Hmm, during the Packaging, it does seem like the DataTable that is used for the Rich Image Text Block is unable to find a package for it to be placed in:

PackagingResults: Warning: Unable to find package for cooking /Game/ButtonImage
UATHelper: Packaging (Windows (64-bit)): LogInit: Display: LogLinker: Warning: Failed to read package file summary, the file /Game/ButtonImage.uasset" is unversioned and we cannot safely load unversioned files in the editor.

[split flare]

Yeah, the Widget is created in a "Create Widget" node. The Widget class (which has a reference to the RichImageText/DataTable) is a variable set on the Prompt that creates said widget.

[craggy cobalt]

hmmmmmm was the uasset added to the project from outside the editor?

ie, by just putting it into Content from your file manager?

or is it actually talking about version control- are you using a version control solution?

here is the editor source for that error https://github.com/EpicGames/UnrealEngine/blob/c3caf7b6bf12ae4c8e09b606f10a09776b4d1f38/Engine/Source/Runtime/CoreUObject/Private/UObject/PackageFileSummary.cpp#L138

doesnt have to do with version control, has to do with the file format version of that file

[split flare]

Interesting, thanks for the link. I don't think it was created outside the editor, but I wasn't the one who created it originally. We use p4, it doesn't seem like the uasset was added from outside the editor. I'm trying to re-create the asset since its just a small datatable now

no cooking complaints in the logs so far, which seems promising

Welp, those cooking warnings in regards to packaging went away, but it seems that the assets are still missing from the Rich Text Block Images.

If the Level is loading asynchronously, would that have any implications to this asset not loading if we're not also doing anything special to load these images? We don't have anything set up in the Asset Manager for Primary Asset rules, but we are using Stream manager to load in the Level.

[winged moss]

that seems like a weird way of loading a level

but as long as there's a hard chain of references, there shouldn't be an issue

our game uses rich text image sets and not really had issues with those sets not packaging

[hot light]

hey, short question, first time shipping with 4.26.2, but now steam drm/wrapper says: Executables with a TLS callback can only be wrapped in compatibility mode.

never had that problem before, something i should be worried or its normal on that unreal engine version?

with 4.24 i could wrap it with normal mode just fine

[ornate plover]

hey guys, sup? For some reason my render target shader is blurry in packaged game. It works fine in the editor. Does someone know a possible reason?

[humble pilot]

did you try to update steam skd in your project?

[humble pilot]

some things in editor looks pretty good because ue4 uses iterative build, try to test your shader using stand alone play mode

[split flare]

Follow up for posterity:

Rich Text Block Decorator Classes **must **have a Text Style Set. In Editor won't complain about it, and it just won't work without one in the packaged build.

[winged moss]

I'm not sure how you expect that to work even in-editor

[stark marsh]

Anyone know how I can load different dependencies for different build targets? https://forums.unrealengine.com/t/how-to-load-different-dependency-modules-for-different-build-targets/239470

Anyone building UE5 on CI(or via commandline)?
I have a problem that the exact same command on UE5 will give me Windows version but not WindowsNoEditor, did any of you guys had similar problem?

[hot light]

@humble pilot i updated the sdk files in the engine folders shoud be enough? its been a while till i did the sdk stuff...

but atm still the same TLS callback stuff

[hot light]

i just tested, if i ship the standart third person template in 4.24 i can wrap it with standart just fine, if i create the same standart third person template in 4.26.2 and ship it, the steam wrapper says its has a TLS callback

They renamed

its mentioned in the documentation somewhere

Is there any way at all for a packaged game to use an external fbx for a mesh? like...being able to reimport an asset on a specific folder on runtime?

[oak tiger]

Hello, all. When I use the UE 4.24.2 Project Launcher on macOS to prepare a build for Steam distribution, the build completes but I have noticed some very strange behavior: I can launch the game from the output directory, but if I move the game .app output to a different folder, it no longer launches (MAJOR ISSUE)!! This means that the game no longer works when I copy it to ContentBuilder folders and similar. What am I missing? Thanks!

[next dust]

Oh, soo i need to adjust my CI scripts 😄
Thanks for the info 😄

[weak folio]

hey guys how do you change the packaging name? whenever I do so in project settings my APK build fails

[swift harness]

Hello Everyone I hope you guys are all having a great day
I had a question: when I play my small game on my unreal editor the small video that is playing on the beginning as a widget is playing fine but when I package for Windows the same small video goes all white! what can I do to fix it?

[craggy cobalt]

if you are constructing a reference to it using it's path under /Game, then likely the packager doesn't realize it's being used at all and is being dropped

if it's a movie file you can put it under Movies which is special and is always packaged, or you can go to Packaging settings and tell it to always package the folder it's in even if it can't see any references to it

or you can change how you construct the reference to the movie so that the packager knows it's used, such as by making a variable that defines the movie to be played and setting it in the Details panel instead

the last one is preferable

if u think it is indeed being packaged, disable Paks and go look in the packaged output to confirm it's there

[regal elbow]

When i start my ue4 game on my other laptop it gets an error: Couldn’t Start create process () returned 2 how do i fix this?

[craggy cobalt]

did you build for win64 but your other laptop is running win32 or vice versa

[regal elbow]

I build it for win64

[orchid star]

is there a way for ue4 to spit out multiple paks instead of just one?

[vital creek]

You can configure certain assets to belong to certain chunks if that's what you're asking: https://docs.unrealengine.com/4.26/en-US/SharingAndReleasing/Patching/GeneralPatching/CookingAndChunking/

[regal elbow]

I want to let players download my .exe game but i tested it, and i started the game it gets an error

[mossy apex]

Are you downloading only the executable or the whole build folder?

[regal elbow]

Only the executable

[craggy cobalt]

you need the whole build folder

ie not just the .exe, but Engine and your game folder and these manifests

[regal elbow]

Ok

Thx!!

[inner island]

Can someone what caused this - do they mean video memory? This sucks because it's basically rebuilding ALL my shaders in the ENTIRE project - (most were already compiled) ATHelper: Packaging (Windows (64-bit)): LogCook: Display: Cooked packages 5487 Packages Remain 7656 Total 13143 UATHelper: Packaging (Windows (64-bit)): ** LogCook: Display: Used memory high 16990608 kb, exceeded max memory** UATHelper: Packaging (Windows (64-bit)): LogCookCommandlet: Display: Detected max mem exceeded - forcing shader compilation flush UATHelper: Packaging (Windows (64-bit)): LogCookCommandlet: Display: Flushing shader jobs, remaining jobs 31177

[craggy cobalt]

that's regular memory. It does need to recompile all the shaders from your project at least in some cases. Check the RHIs you have enabled in project settings, and then double check them in the INI files because project settings can get confused, this happened to me where it was building ES 3.1 model shaders in addition to SM5 and it was choking on a shader that didn't work in es 3.1

once packaging has completed successfully, the result will be cached and you won't have to next time

[inner island]

Weird - I've packaged this project many times - (like 15 in the past three months) - I did add some more assets, particularly some that had a bunch of material instances with like 5- 8 texture parameters - but I guess what weirds me out is it wasn't like a project setting - it literally said, "exceeded max memory" so the solution to that is to just rebuild all the shaders?

all I know is, it's been recompiling shaders for literally 8 hours

I wasn't ready to package but I wanted to run through just in case I encountered some problem/bug I would know about it - I'm glad I did this earlier than waiting until the day I needed it to be packaged

and like you said, as long as this packages correctly, I shouldn't have to worry about it again

[ornate echo]

Hey guys !
I've been debugging the log of my game the last few days and every thing is fine except for a recurring warning stating "Component NOT supported"

But the component does work correctly in the game, I just mind because it is spamming my logs.

HOW TO FIX

[gilded night]

Hello, I have a package problem that I do not understand, I passed a project from 4.25 to 4.26 but since trying to build I have this error if someone would have the solution (PS : I have already deleted the intermediate file and the line with the white arrow I have the impression that it will not look for the correct Binaries folder)

[mint leaf]

delete binaries and intermediate

can delete saved too

[severe mural]

hey, getting this error while packaging, anyone knwo a fix?
LogAssetRegistry: Error: Package ../../../../../Code Projects/UE/Flux Entertainment/SCP-Infinity-Github3/Game/betterbeworkin/Content/Menus/Option_Menu/Options_Menu_Widget.uasset has malformed tag

[strange ledge]

Are you sure you can see this file in ue4 editor? in file system? try to fix redirectors on content folder anyway.

[mint leaf]

Yes, if you install each dependency, but installing the prerequisites is usually easier the first time

[mellow bane]

You have the distribution platform install them. Steam is a chexkbox for each VS version / DX etc

Itch.io lets you install dependencies, GOG staff will ask you

If using your own deployment, handle it yourself

Sounds like you need to have your own installer that installs the DX & VS redist

Or the Unreal provided one if you have Blueprint only

[mint leaf]

You have to figure out the dependencies and script a bunch of MSI installers, or use choco packages etc

[mellow bane]

Get DX redist, VS redist, put them in your package, and have your own installer software run both at install / update time, with the appropriate command line parameters

If you have no C++ or nativized BPs you can simply run the Unreal provided one

It used to have a silent option, btw, so check its command line params

You only need the redistributable installer provided in your packaged folder by default

have your installer run it

[mint leaf]

I cant think of a reason why anyone knowing what your prerequisites are (like VC, DX etc) is a huge issue

[mellow bane]

"I don't want the player to install the prerequisites at all, or even for the Unreal Engine logo to appear" is a fairly trivial ask, it's what players are used to and it's what Steam etc will give you

[severe mural]

ye its just there it exists, should i move it to a new location or something?

[strange ledge]

try to fix redirectors on content folder and fullrebuild first of all

i'm trying to package my project for android, unreal sends me to the page that's 404'ed. can anyone point me to the direction of right tutorial?

[open rapids]

@mint leaf thank you but why answer at all if it is too hard for you to be helpful without being an asshole?

can't you just leave the question alone and let someone with more tolernace for noob questions answer it properly?!

[mint leaf]

I wasnt being, but as you wish

[open rapids]

You literally sent me to LMGTFY (which you removed for some reason), which clearly says for what it does exist. Only thing is - i wasn't bothering YOU, i asked question, you bothered yourself to answer it, you as anyone else could just walk by without answering and i would be just fine with that, but u decided to try and make fellow human being feel shitty. That's textbook definition of asshole. Just keep that in mind for the future when you try to act like that.

[mellow bane]

Check this page out, it has the prerequisites listed on top : https://docs.unrealengine.com/4.26/en-US/SharingAndReleasing/Mobile/Android/PackagingAndroidProject/

The engine autodetects required software and puts you on an apparently outdated doc link if it failed

[open rapids]

@mellow bane Thnx alot, yeah it did that.

[open rapids]

i followed setting up instructions step by step, everything went flawlessly only problem is that whenever i try to build, it still sends me to that broken 404 page

I'm working on a project that uses blueprints and nothing special outside of the core engine. Aside from control and camera differences, can I expect any other issues when compiling for oculus quest 2, android, and PC?

[dawn stream]

Hi, I'm trying to chunk up my game as it takes ages to patch when I submit a new build to Steam. I've set the maps to be in different chunks, but it's actually generating a much larger package now. Any idea what I'm doing wrong?

[mellow bane]

Chunking will be completely pointless for that - Steam already does perfectly efficient patching

As in, binary diff of each file

No idea about the actual problem but in nay case there's no making this faster, short of having less changes

[dawn stream]

@mellow bane Oh right. I'm doing 10~meg changes and it takes 20-30 mins for people to patch though

Steam actually says 'over a year' for a while when giving the time

[mellow bane]

How much upload does speedtest.net give you ?

Are you sure it's a 10MB change ?

Like, rebuilding lightmaps could look like a 10MB change while being a 10GB one

[dawn stream]

Yes even if I just change a blueprint it takes people a long time to patch

it's happening to all the testers so I don't think it's my upload speed

How can I check what the actual patch size is? Maybe it's rebuilding something automatically every time?

[mellow bane]

"Preview change" on Steam dev page (builds page)

"Update Download Size"

[dawn stream]

oh those are always low

[mellow bane]

That's what's being uploaded and downloaded, AFAIK

[dawn stream]

they're around 10meg

[mellow bane]

Sounds like everything is working fine, you can check your network usage while uploading to see if more is getting up

[dawn stream]

yeah I could

[mint leaf]

I blocked the dude, calling people assholes isnt exactly a way to get people to help you.

android is usually a fun experience getting all the toolchains and bits required for google play

[red zephyr]

how so?

[mint leaf]

mostly the google play stuff

and project setup

[red zephyr]

oof, that bad?

to start, I just want to give apks to testers to sideload, but is adding all the stuff to get it on the store late in a project a bad idea?

I'm pretty new to UE and game dev, I clearly haven't done much platform-specific research yet (keep textures small, take into account screen sizes and control limitations and low-power hardware, is basically what I know)

hey guys, I'm having an issue with loading savegames in a packaged game, both in Development and Shipping builds. in a Dev build, DoesSaveGameExist returns true, but loading always returns invalid/null object
does anyone know why this might be?

I tried making sure to include the directory that includes the old SG class (I actually included the parent folder of the one it's contained in)

a couple of details: this is for an update function, a lot of old record savegames are being consolidated into one master record savegame, so it is saving and loading them in succession.
two: I have been pasting the saves over and over again from a backup trying to get the update functionality to work correctly

Did anyone else get "ERROR: Visual Studio 2019 must be installed in order to build this target.
PackagingResults: Error: Visual Studio 2019 must be installed in order to build this target."

[mint leaf]

its not that hard, but the first couple times it takes a really long time to get all the stuff setup correctly - though the first time I did it was like 2014 and the documentation was, spartan, shall we say

[mellow bane]

You probably need to install VS 2019, as the error says.

[rocky scaffold]

ok , is that different than selecting it here

[mellow bane]

Yeah, you need to actually download VS 2019 Community and install it

With the C++ Desktop workload

[rocky scaffold]

Ah ok, thanks

[mint leaf]

You do need VS for BP only projects right? Its been a millenia since I did any BP only project as it doesnt work in CI

[mellow bane]

You don't, as long as you have no C++ plugins or nativized Blueprints

[mint leaf]

Ahh thatll do it, the code plugins

[rocky scaffold]

Funny cuz im using a BP project

[mellow bane]

Sounds like you have code plugins or nativized Blueprints

[mint leaf]

I havent used blueprint only basically ever because you cant commandline build it

[rocky scaffold]

Ah ok, so shud i search these to unable them or just continue with VS fix

[mint leaf]

if you disable they might break something

just install vs

[rocky scaffold]

Ok, installed

[mint leaf]

its a problem Im going to have to try and solve eventually for my CI service, but for now I just state, if you want your stuff to work, use a C++ project or add blank C++ classes to every level you want baked

[mellow bane]

What ?

[mint leaf]

Oh I am creating a tool that lets you just click a button and get builds

[mellow bane]

What is "use a C++ project or add blank C++ classes to every level you want baked" supposed to mean ? If you don't use C++, you don't need C++

[mint leaf]

but havent (upto now) bothered working out how to compile BP only projects in it

[mint leaf]

The UAT stuff needs a C++ class or it cant bake lighting via the commandlet

[rocky scaffold]

Im guessing all these wouldn't be necessary

[mint leaf]

just click desktop development with C++ under workloads and uncheck the Unreal Engine installer

[rocky scaffold]

Its funny bcuz i dont even see it in that list haha

[mellow bane]

"Workload" tab

"Desktop development with C++"

[mellow bane]

i initially posted in #plugin-dev but maybe I should've posted here? I am trying to package a plugin but i get an error on VS2017, I have VS2019

I found this answer but I am no sure what to do with the info, I found my RunUAT.bat but where am i supposed to pass my parameter?
https://answers.unrealengine.com/questions/975709/need-vs-2017-to-build-plugins-in-425.html

[mellow bane]

Check for Win10 SDK, MSVC in the VS installer

[open rapids]

guys i followed android SDK installation to the teeth and i get this error at the end of the build:
||UATHelper: Packaging (Android (ASTC)): ERROR: cmd.exe failed with args /c "D:\UProjects\NewMobile1\Intermediate\Android\armv7\gradle\rungradle.bat" :app:assembleDebug
PackagingResults: Error: cmd.exe failed with args /c "D:\UProjects\NewMobile1\Intermediate\Android\armv7\gradle\rungradle.bat" :app:assembleDebug||

tried following this tutorial aswell, didn't helped: https://youtu.be/BD7YbzapSQE

[tight fjord]

@mellow bane seems i am missing several updates in VS 2019, gonna update a bunch first and look into those modules

[tight fjord]

So i have those installed on the latest

oh, i see this:

[tight fjord]

well i went to 4.26 and now i get this:

is there a way to not package for android at all? I just installed the SDK but I am not even building for it

[open rapids]

@tight fjord 4.26 seems too broken for anything that involves android from what i can gather.

rolling back to 4.25 solved all java/android sdk/ndk related problems alltogether.

[tight fjord]

yeah but 4.25 requires VS2017 to package

I'm trying to whitelist the build.cs

[open rapids]

i have vs2019 installed

is there something specific that u need vs2017 for?

[tight fjord]

it just tells me i need vs2017 to package my plugin

see above a few messages

wow... UATHelper: Package Plugin Task (Windows): ERROR: Visual Studio 2017 must be installed in order to build this target.

again

[open rapids]

for which platform?

[tight fjord]

win32/64

it's a plugin

[open rapids]

will try building for windows and get back to you

[tight fjord]

like create a plugin then package it in 4.25 or 4.26

you will get an error saying it needs VS2017

[open rapids]

packaged properly

with ue 4.25 and vs2019

did u installed vs2019 from microsoft site?

my vs2019 came with unity, that might be the case

[tight fjord]

yeah and i even code on it no problems

somewhere there is a link made that wants vs2017

I linked an answerhub answer that mentioned modifying the runUAT.bat but i dont know how

[open rapids]

have u tried just clean installing everything?

cleaning registry and such

[tight fjord]

at that point might as well install vs2017

[mint leaf]

You should be able to pass -2019

[tight fjord]

This is my question: where?
@mint leaf

I just tried 2 cmd but they didnt do anything

[mint leaf]

Ill have a look when im back at pc

but when you build UAT or do gen project files iirc

[tight fjord]

I'm using this:

[mint leaf]

you probably need to setup the engine to use 2019 when you install

I only use command line

[tight fjord]

i never used anything else other than 2019!!

oh lord...

[mint leaf]

it sounds like you built automation tool targeted at 2017 if you are using a source build

[tight fjord]

how can this be changed?

[mellow bane]

It does not, for what it's worth

I haven't had VS2017 installed for the past 2 years

What you do need is a valid C++ compiler and Win10 SDK

There's also no need to pass UAT parameters or set up anything at all

"2017 is required to build" has long been a red herring, the message simply was never updated

[tight fjord]

@mellow bane

and this?

[mellow bane]

Looks fine. Do you also have 2017 installed ? Having it installed without a compiler is a typical issue

[tight fjord]

i keep hearing people are passing in command lines and parameters, can someone just tell me how to do it once, at least where... it's all fine and dandy that it works for you and that's great and all you didn't have to do anything but it doesn't resolve anything on my side.

[runic stump]

You can sneak-peek into editor output log and grab RunUAT commandline from it. And then just run it in cmd.exe, without running editor at all.

WRT your issue - I'd just install vs2017. UE4.x defaults to 2017 here and there (and Epics use 2017 for official engine distribution via launcher), so it just works smoother.

[mellow bane]

There is no need for 2017 at all

Asking again since there was no answer : Do you also have 2017 installed ?

[tight fjord]

i just finished installing it, fails to copy files now and build fails

the Win10 SDK seems to be limited to 177

[mossy apex]

why do you guys use vs 2017????

[mellow bane]

No one is

[tight fjord]

because the bloody engine keeps asking me to use it

[mellow bane]

10.0.18362.0 is what 4.25 compiles against

[tight fjord]

and as much as i ask around what to do to make it use my 2019 VS, nobody has an answer

either its already set in your systems, somehow

[mossy apex]

i think to get all features it is better to use 10.0.19xxx.0

I used to be a DX12 game dev

[tight fjord]

what the heck does that even mean?

[mellow bane]

2017 has not been a requirement for very literally years, that message is a mistake, it's just never been updated

Let's work on the actual issue

Again : Do you also have 2017 installed ?

[tight fjord]

yes

[mellow bane]

So you have 2017 and 2019 ?

[tight fjord]

yes

[mellow bane]

Did you have it before or is that a new thing ?

[tight fjord]

new thing today less than an hour ago

[mellow bane]

Okay, but this isn't helping - 2017 is not needed

[tight fjord]

ok, moving on then, what now?

[mellow bane]

Uninstall 2017 completely, package again, put the error log on pastebin

You can read the 4.25 release notes for official version requirements, btw

[tight fjord]

installer taking its sweet time...

yeah i saw them

which is why i was confused

[mellow bane]

Windows
Recommended:
Visual Studio 2019 v16.5
Minimum:
Visual Studio 2017 v15.6
Windows SDK 10.0.18362
NET 4.6.2 Targeting Pack

This is what I'm running here - French, sorry, but versions are the same:

[tight fjord]

that's fine, i speak it

[mossy apex]

same

[mellow bane]

What's TopDownPhysicsCamera here btw ?

[tight fjord]

a plugin i made

imitates TLoZ classic camera styles

alright lets check 2019

[mellow bane]

There's a 2017 compiler here that's not needed or helpful, and no WIn10 SDK

[tight fjord]

they are checked when i looked em up

these are the basics accoding to the documentation

[mellow bane]

I'd remove the VS2017 compiler (make sure you have uninstalled 2017 entirely) but okay, looks good

If the plugin still refuses to compile, check out the build.cs and target.cs files

[tight fjord]

gonna rerun the packagin

sec

[mellow bane]

The game code successfully compiling before the plugin fails kind of suggest the plugin might do something weird

[tight fjord]

just had a 10s blackout... restarting

it has -2017

thats why its using 2017

hence the comment earlier you need to pass -2019, the trick is where is that setting in the UI

@tight fjord what plugin is it?

[tight fjord]

it's my own?

how do i pass -2019? where!!! where!!!

[mint leaf]

Also, can I suggest, try packaging for just win64 rather than trying to build 5 things at once

[tight fjord]

i only whitelisted win64 win32 and mac...

no idea why it packages for all

        {
            "Name": "TopDownPhysicsCamera",
            "Type": "Runtime",
            "LoadingPhase": "Default",
            "WhitelistPlatforms": [ "Win64", "Win32", "Mac" ]
        }```

[mint leaf]

is the project you are testing in setup for all platforms?

As I said, im not expert in the UI, I do all via command line
I did just make a test project and it packages fine with 2019

so its a config issue of your engine/project

Is this a source build or launcher binaries?

[tight fjord]

no idea what any of those are

[mint leaf]

Where did you get your engine?

the EGS launcher?

[tight fjord]

yeah

[mint leaf]

4.26.2?

[tight fjord]

4.26.0

[mint leaf]

in project settings

did you set 2019

for toolchain under Platforms - Wondows

@tight fjord

[tight fjord]

yes

[mint leaf]

Did you save the uprokect out

and check the change

Ok right

In project settings, set 2019

Uncheck everything aside from Win64 to build

I managed to replicate the behavior via the UI

I know why its doing it, I just dont know how to fix it in the UI

[runic stump]

Ask epics, why they build ue4.2x with vs2017.

[mint leaf]

tldr the editor is creating a command line which isnt actually correct

I only ever build directly on command line so I didnt run into this

[runic stump]

I have some issues trying to look at editor code currently. Does it unconditionally pass -2017 or there is some kind of a setting?

[mint leaf]

it seems to

maybe you have to edit some part of the uplugin to force it

but I dont ever do by editor so I actually dont know

deffo a weird one

Does anyone have an idea how to solve it

[mint leaf]

Put the full log in pastebin

[undone sleet]

This is the complete log

[mint leaf]

You probably moved some structs and didnt update the redirects

if you rename each referenced struct one by one, it will update the redirects and probably package

You can also try File -> Refresh all nodes

in each of those BPs

[undone sleet]

It is one structure. After renaming I searched for the structure and did update node

But if it now fails again I will try it as you said

Strange. Now it worked. The problem seems to be that the structure was given through a interface call. In the files giving the errors the event wasn’t used, because it was not necessary. Now I just said in them implement event so I get the event, but don’t have any code behind it. So it worked. But thanks for your ideas

[mint leaf]

yes the rename usually fixes it

what is this error i googled it and literally nobody but me has the same error

UE4 even says this before this error:

UATHelper: Packaging (Windows (64-bit)): LogInit: Display: Success - 0 error(s), 425 warning(s)

[jagged seal]

by chance, does anyone know the differences between debug, debugGame and Test build configurations in the Project Settings ?

nm, found docs..

[mellow bane]

Your code is using stuff from the EditorStyle module which is off limits for packaged builds

Directly or indirectly through a third-party plugin

[meager axle]

how can i make it not do that?

[mellow bane]

Well, don't use editor code in your game, basically

First step should be to identify where you do that

[meager axle]

I somehow fixed, unfortunately i dont know how, so i cant explain it but thanks anyway. I will keep all the advices here in mind if i ever get same error.

[mellow bane]

Alright, fun question - I have a folder that is excluded from packaging, content inside only referenced inside WITH_EDITORONLY_DATA ifdefs ; but the assets still cook, though I don't believe they end up in packaging thanks to the exclude

Any way to prevent cooking ?

[mellow bane]

Seems to me that "directories to never cook" should prevent cook, not just packaging

[pale sequoia]

OK I've been struggling to package my project for 4+ weeks now, can anyone here help me with building for android? I feel like its something to do with the Android Studio install but I've reinstalled it 3 times now.

[regal elbow]

Hi! How can i update my game? For players who download the old version already

[fringe pond]

Hello, guys!
I have an non-understandable bug.
So, i have a project. It packages fine on windows from Editor, fine from command-line (RunUAT and so on), and fine from UnrealFrontend.
Also it packages fine on MacOS from Editor and fine from UnrealFrontend. But when im trying to package it from command-line, it always fails on cook stage. First of all, it doesnt pass some JsonTests (i tested it with automation tool -> it passes fine in editor). I commented out this tests just for testing, and now cook fails with another reason. I cant get, whats the problem, why everything is fine in editor, but if i copy command to package and place it in bash script -> it failes.

[waxen flame]

anybody knows how to fix this?

when I package my game for Android

[mint leaf]

You have to build or use a delivery system, like itchio/steam has

[regal elbow]

Thanks!!

[quasi valve]

Hi, I've got a package problem that's really eluding me. Below is a screenshot. I've tried following other comments I've seen on google like attaching a visual studio debugger to the engine. I did that, found the bad variable that was causing this in the first place and removed it. The engine now launches just fine w/o any breaks, but I still get this error with packaging:

I'm at a loss for how to solve this since I don't get any errors about ShortPackageName on start of the engine, just when I package it. I did a notepad++ find in files for NoneNone, but nothing came up either

[craggy cobalt]

do you use soft object variables in blueprint somewhere?

Kismet = blueprint-- it sounds like perhaps the type was changed to soft object reference but the default value wasnt fixed or something. Also, do you have custom C++ in your project?

it could also be a parameter into a blueprint function that is a soft object reference- and the error is occuring because the value provided by the caller was a string when the function call node was created, and it was not correctly updated to None when the input parameter became a Soft Object reference

recommend go finding any blueprints in your project that touch soft object references and hitting Compile on them

[quasi valve]

I didn't think I did, but I've been not so great at cleaning up old blueprints. If I recall I might've started something off as a soft object, then swapped it over. I'll have to dig around and see what I can find then

Is there a good way of tracking down where soft object references would be, short of just opening up each blueprint?

My only lead at the moment is a struct that crashes the entire engine when I save

[craggy cobalt]

I'd say thats a solid lead

[runic stump]

So attach debugger to UE4Editor process that does the cooking.

[quasi valve]

I wanted to do that! But I'm admittedly a noob when it comes to attaching debuggers to things (as in I found out how to do it today). I had it attached to the UE4Editor.exe process, I couldn't find how to attach it to the one doing the cooking

Is there a way to dive into that process specifically? Or some sort of tutorial how ot?

[craggy cobalt]

use Attach to Process in VS and aim for the one that looks busy when cook starts :-)

[quasi valve]

That did it, I had to flag it for all users to get the one unreal was launching

[quasi valve]

My game is packaged! Thank you SO much @craggy cobalt and @runic stump !!

[craggy cobalt]

so it helped you find the particular blueprint to recompile and fix?

[quasi valve]

Yep. Turns out it was hiding in a blueprint that was never actually used

the callstack pointed me to the var and the blueprint

a humbling lesson in, "clean up your work"

[craggy cobalt]

yeah and if you do have any custom C++

then for the love of god dont hotreload (ie the Compile button in the editor for one thing)

this kind of stuff becomes the norm if you use it

[quasi valve]

Oh that's good to know, I don't have any custom C++ assets yet, but that sounds scary

[craggy cobalt]

ok good, then it wasnt the cause here. but yeah if you add some C++, be forewarned. it is the scourge of #cpp

[quasi valve]

Thanks for the warning! Time to collapse, thanks again for the help

I keep getting this error when packaging for android and I have tried everything I can find online

[dawn stream]

Hi, I still have issues with my Steam game taking 20+mins to update even tiny patch sizes (5meg or so). Steam will say it's going to take over a year to patch. This is happening for almost everyone, even on solid state drives. Any idea what I'm doing wrong? The game itself is 30 gig.

[winged moss]

using pak files?

[dawn stream]

yep

[runic stump]

You may want to split game data into multiple paks. Steam doesn't apply patches inplace. For each modified file, it writes a new one with updated contents and then moves updated file on top of old one. So, if you have a single 30gb pak file, you need to read/write 30gb on disk even for the tiniest change in game data.

See https://docs.unrealengine.com/4.26/en-US/SharingAndReleasing/Patching/GeneralPatching/CookingAndChunking/

I'd start with moving each map into a separate pak file.

[dawn stream]

Ah yes I started doing that but someone here mentioned it wouldn't work, I'll keep looking into that route then 🙂

[open rapids]

Hello i have a problem with packaging my levels, so i had around 12 levels selected in asset for my package, but now i need to do only 6 levels build, so i remove all levels i dont want from assets in projekts settings, but it looks like all 12 levels are still in the package. Once i even enter the deselected level. Is there other ways to remove those levels ?

[mint leaf]

check its not in "maps to cook"

[errant cliff]

Anyone know how to deal with this. Already spent 5 hours on it...

[mellow bane]

Bumping this nice little question, in case someone knows. I have a folder that is excluded from packaging, content inside only referenced inside WITH_EDITORONLY_DATA ifdefs ; but the assets still cook, though they still don't end up in package thanks to the exclude. Seems to me that "directories to never cook" should prevent cooking, not just packaging. Thoughts ?

[open rapids]

@mint leaf how can i check maps to cook ?

[dawn stream]

Hey I went through the article you linked and split the project up into smaller PAK files (2-3 gig rather than one 30) but the same issue occurs; 15 minutes to update a 5mb patch. Any clue what I'm doing wrong there?

[tight fjord]

I'm trying to run the following command but nothing happens:
runUAT.bat BuildPlugin BuildPlugin -Plugin="Q:/.../TopDownPhysicsCamera.uplugin" -Package=C:/.../TopDownPhysicsCamera -CreateSubFolder -TargetPlatforms=Win32+Win64 -VS2019

am i missing something?

[dawn stream]

I’m going to try packaging without pak chunks; it looks like the entire folder structure and all files appear in the built folder though. Is that normal/OK?

[mellow bane]

Without pak you mean ?

Yes, that'll be normal

[dawn stream]

And it’s alright to upload games to steam with all those files? Apart from ppl seeing how messy I am 😂

[mint leaf]

project settings...

[mellow bane]

Why would you not use paks though ? Loads faster, looks cleaner

No downside

[dawn stream]

I’m still getting 20 minute patching times for 5mb updates @mellow bane

Even when I split the 30gig pak file into smaller 2-3gig ones

[mellow bane]

That's not caused by paks

Thought I had that explained already 😛

[dawn stream]

Yes but I can’t find any other explanation

[mellow bane]

Do you have encryption enabled ?

[dawn stream]

I don’t think so

[mellow bane]

If you're not sure you don't

And as long as Steam's builds page tells you the updates are actually 5MB, your 20min time is either really slow upload or a slow CPU for the delta patching

[dawn stream]

It happens to all of my players so I doubt it’s related to connection/cpu

[mellow bane]

Did you confirm that the patch size in Steam's builds page is 5MB ?

If it is, then the patch is actually 5MB

And your pak is not the issue

[dawn stream]

I did yes

But I read that Steam has to unpack the Pak, patch the file, then re-pack it, which would imply that large chunks would still create longer patch times

[mellow bane]

That's not true

Steam isn't capable of unpacking your pak file

It doesn't need to, either

It's actually likely that processing a pak file would be faster than patching thousands of individual files

[dawn stream]

What could be causing this then?

[mellow bane]

No idea, really, 20 minutes sounds way too much no matter what

[dawn stream]

Yeah it tells people it’ll take over a year

[mellow bane]

How big is the pak file itself ?

[dawn stream]

If it’s just one then 27gig, but now it’s several, most are 2-3 gig but one is 12 gig

To test this I’m editing a single file in one of the smaller chunks

[mellow bane]

Okay, now one 27GB file might start explaing things to some extent

[dawn stream]

Yes it’s still happening with the smaller chunks though

The only thing I can think to try is to break up the chunks even more

Could it be that one file is referencing loads of others?

[mellow bane]

No.

Steam doesn't know, or care, about what your files contain

It has zero knowledge of which engine you are using and isn't capable of understanding what your pak files contains

It's possible that you have a change in the 12Gb file and that Steam somehow needs to rewrite the entire file

I find that surprising because my 4GB game with a single pak didn't have such a problem - updates were pretty instant

[dawn stream]

@mellow bane So I tried a build with no pak files and it worked super fast, so it's definitely an issue with the pak files

[winged moss]

patching pak files is slow because steam rewrites the pak file

that's why the patching system for pak files exists

patching individual files is actually faster via steam's patching system even though it's slower reading them due to seek times on HDDs

[dawn stream]

@winged moss what sort of size should I be getting the pak chunks down to?

[mellow bane]

The important part is writing to only one chunk

If you have 10 1GB chunks but change all 10, it won't affect the result

By the way 27GB is a lot, most games I own are a lot smaller than that - make sure you have compressed paks, only used content, etc

[dawn stream]

Is there a list of things I should be using? I don't use compressed as I read it can hurt the updating time. I also don't have 'only content' on

I'm just using defaults I think

[mellow bane]

Compressed will not hurt the update time, it will reduce it by a large margin

Since, you know, it'll reduce your 27GB to 10 at most

By default Unreal will also include the entire project content because there's no way to know what's used

Make sure to fill the list of maps used, in the packaging settings, so that only items referenced through a level are included

[dawn stream]

aha ok great, I'll give that a go 🙂

[mellow bane]

Also https://docs.unrealengine.com/4.26/en-US/TestingAndOptimization/PerformanceAndProfiling/ReducingPackageSize/

[runic stump]

I think you can ask steam to show what files exactly differ between patches. If those 5mb actually change each and every pak (after splitting chunks), then the root of the problem is in cooking/packing.

Actually even without paks at all, checking what files change between patches could give some hints. Possibly some assets, that you do not expect to change, do change (and these assets, when stored into paks, force lots of pak files to be patched).

But this is just a guess, we need more data/experiments to be sure.

I saw a game that changed serializable fields during asset load. So, such asset was always different when it was cooked, thus pak file with this asset was always different, thus steam had to patch it every time.

cook commandlet even has "diff mode". it is used to track down such cases.

[dawn stream]

Awesome thanks for the help

[dawn stream]

Just an update, the issue is now fixed 🙂 Thank you so much @mellow bane and @runic stump. It was a combo of using compression, setting only certain maps to load and splitting up the game into more pak files.

[bitter thicket]

This project built sucsessfully a few days ago. Made some changes, and now is stuck at this stage. Any ideas as to where i can start troubleshooting? I have left it run for a couple of hours, and just keeps outputting the above message.

[warm orbit]

Not sure where to ask, but can I use GPL license for a game?

[mellow bane]

No

The (L)GPL is explicitly forbidden in the Unreal EULA, and should be obviously impossible to use, since it contaminates all code

Valid OSS licenses with Unreal would include MIT, BSD, etc

[warm orbit]

But LGPL is allowed if it linked dynamically, but I can't link the game code dynamically, right?

[mellow bane]

Indeed you can't, and so the LGPL is out

Again, both GPL and LGPL are explicitly forbidden in the EULA, so there's no point arguing

[warm orbit]

Thank you a lot for the clarification!

[runic stump]

Things are a bit more complicated.

You can create LGPL library (completely unrelated to unreal engine).

Then, you can create Apache/MIT/BSD/whatever game code that would link to UE and dynamically to your LGPL library.

I believe, such construction complies with both LGPL and Unreal EULA.

[warm orbit]

Sure, sounds logical. But If I understand correctly, the game code can't be released under LGPL, it's sad :(

This is what I basically asked, sorry for confusing. But you answered to my question very clearly. Thank you!

[runic stump]

There's another option via dlopen.

Say, I write BSD game code that dynamically loads all dlls from a dir, searches in each of them for a function foo (by name) and calls it if such function exists.

Now i write a GPL lib that has function void foo() and place it in that dir.

TaDaa! We have both things in one process. The point of defense of this construct is that game doesn't link to any particular lib. GPL lib didn't even exist when we wrote/compiled game code!

[runic stump]

Well,it depends on the game. I could imagine games where 90% of code would live in that lib.

[runic stump]

Actually, this is exactly what libglvnd does to decouple vulkan apps from vulkan drivers.

[mellow bane]

Yes you can do that but you would not be able to use a single line of the engine API in your game DLL, so it's pretty much pointless

And again, the EULA specifically outlaws GPL and LGPL so it doesn't matter of you can think if a valid legal workaround (which you did) because Epic might still demand you cease and desist

Not a lawyer etc, just suggesting to stick to simple stuff - BSD, MIT, etc. No issues with those :)

[warm orbit]

By the way, the engine supports Linux. This means that it uses its functions to support it, which are GPL. Why is this legal? :D

[mellow bane]

Mostly because you ain't distributing Linux

Contrary to Windows stuff you aren't even shipping the compiler's runtime

You're just releasing a binary that calls stuff and no license in the world has a problem with that

In fact, GCC for example has an explicit GPL waiver for its std library, so that you can compile proprietary programs with it with no issue

[warm orbit]

So the issue in distributing the engine binaries that linked with GPL code? But the engine itself use GPL code.

[runic stump]

Engine doesn't link to GPL code.

[warm orbit]

But how? To use dlopen it should be linked with dl

[mellow bane]

The engine license says "no GPL or LGPL"

If it did not, a DLL would work, except you'd need a massive layer of glue between UE and your game code

You wouldn't be able to use Blueprint, etc

[warm orbit]

I think I got. The engine can use whatever they want. But the EULA disallows to use (L)GPL code with games.

Thanks

[mellow bane]

It's hard to overstate how impractical it would be anyway

Not to mention it would likely be a breach of the LGPL license on all consoles and mobile platforms

Since the user couldn't swap the DLL

[runic stump]

glibc is licensed under LGPL, not GPL

[warm orbit]

Oh, right, makes sense

[flat marten]

Does anyone here have any ideas on how I can best debug this?

[mint leaf]

are you running onto a HDD

[flat marten]

the engine and the project are on one SDD. I have the same problem on a second computer.

at first i thought it was my game instance and that i have to load too much, but even if i set the default game instance the loading time doesn't change.

Hi
i was trying to cook a build for testing and it seems to spam this error whenever this intel plugin is enabled
problem is it works very fine in editor and i cant seem to understand how it doesnt see the file (location of plugin is in the project)
am i missing something? and sadly google isnt of any help when it comes to

UATHelper: Packaging (Windows (64-bit)): LogPackageName: Error: DoesPackageExist: DoesPackageExist FAILED: '/CapabilityDetect/DetectCapabilities' is not a standard unreal filename or a long path name.

and yes i have almost isolated the plugin and stripped down to baremini and cleaned everything and put in a new project to test and still same error during cooking but i didnt touch plugin it self as it doesnt have anything otherthan 1 function which path it says isnt it

Hey please help!
One computer packages the project without any error, the others are not.
We do not know what causes this issue.(maybe bone reduction at lod levels, but already disabled it).
The engines are identical, the project is under version control, every cache has been deleted.

Hi, I was wondering if anyone here could kindly help? I'm trying to package my project and I'm having issues with Language 'localization'. Here is my settings on the Dashboard

My issue is that I can't find 'Welsh' in my Project Settings... it says it isn't there....

When I package it, the language button doesn't work.. while it works happily in Editor.. Please help, thank you, Diolch (Welsh for thanks)

Hi! How can i update my ue4 game for player who downloaded the old version already

[winged moss]

well unless it's on a platform that supports updating (steam, gog, egs) then you don't, you just send them a new version

[runic stump]

You already asked exactly the same question 3 days ago and got an answer. Why you're doing this?

[wraith heath]

I appear to have fix the localization issue.... no idea how... please ignore above request for help..

[hollow iron]

What's the proper way to add [Staging] to DefaultGame.ini to Whitelist something?

[mellow bane]

Did anyone got primary asset labels to work for designating chunks for content, as of 4.26 ?

Levels work fine, but primary asset labels appear to be completely unable to mark general assets for chunks

[runic stump]

https://github.com/EpicGames/UnrealEngine/blob/5.0.0-early-access-2/Engine/Config/BaseGame.ini#L209-L216

[flat marten]

The problem is solved the editor now starts within a minute.

Apparently all GameplayCues were loaded when starting the editor. The problem could be solved like this:

DefaultGame.ini
[/Script/GameplayAbilities.AbilitySystemGlobals]
GlobalGameplayCueManagerClass="/Script/CoR.CoRGameplayCueManager"

UCLASS()
class COR_API UCoRGameplayCueManager : public UGameplayCueManager
{
GENERATED_BODY()
virtual bool ShouldAsyncLoadRuntimeObjectLibraries() const override;
virtual bool ShouldSyncLoadRuntimeObjectLibraries() const override;
};

bool UCoRGameplayCueManager::ShouldAsyncLoadRuntimeObjectLibraries() const
{
if (GIsEditor)
{
return false;
}
else
{
return true;
}
}

bool UCoRGameplayCueManager::ShouldSyncLoadRuntimeObjectLibraries() const
{
if (GIsEditor)
{
return false;
}
else
{
return true;
}
}

Hi everyone. I would ask whether there's a free alternative to the Epic Games Launcher.
I just need a simple tool that improves the user experience, by automatizing the download of the game, extraction of the archive, installation of prerequisites and game launch. I don't need it for production, just to ease internal testing and demonstrations. What would you use?

[mellow bane]

itch.io

[lilac sandal]

Thanks for your help. I think that it'd be a good solution for a broader distribution. But in my specific case I was more thinking about a tool that would help creating an installer. Is there any installer specific to Unreal or I have to pick one general software installer?

[mellow bane]

There is

Itch.io's butler tool

"installing" is not really a thing

The hard part is updating

Installing is trivial, updating only what changed on a 10GB game is not

If you want to have your players manually download a new version of an installer, go ahead and use a random installer software

If you want smart updates, there's Steam, GOG, itch, etc

[mint leaf]

You can build/hack something together based off some standard code kinda easy

depends if you care about security etc

and how smart you want it to be

[lilac sandal]

Oh wow this seems really promising, even for production, maybe it's worth investing time in it

[mint leaf]

itch is pretty good tbh

its unliukely you can build anything near as good in a short period of time

[lilac sandal]

What do you mean about security?

[mellow bane]

I've used Butler without the itch part in the past and it's a very strong base for a modern installer/updater software

[mint leaf]

So I hacked something together, it just pulls the files off a public ftp/http

[mellow bane]

Itch.io is unbeatable for playtests etc

[mint leaf]

https://gamelaunchercreator.com/unreal-launcher-patch-system/

there is also this

Ive never used it tho

[lilac sandal]

Thank you, that seems also a good option

[mint leaf]

functionally all you need is a tool to pull down the files, it can be done with a few lines of powershell if you dont care about diffing

[lilac sandal]

Are there any guidelines on how to prevent antiviruses to produce false-positive results on the executable?

[mint leaf]

the short easy version, CSCs

[mellow bane]

I also did that a few years ago before Itch was a thing : https://github.com/arbonagw/UnrealUpdater

Clunky and terrible if you use pak files, but works

No diffing either, of course

[lilac sandal]

What is it?

[mint leaf]

Code Signing Certificats

[mint leaf]

I did one with diffing years ago (per file)

was kinda annoying

[mellow bane]

Yeah, I can imagine

Mine above just checks checksums

[lilac sandal]

Ah good to know, I have to definitely look in that

[mint leaf]

when you setup, you had to generate a .checksum file that contained a list of every file with the SHA value

[mellow bane]

Yeah that's basically what I did too

[mint leaf]

These days we have a way cooler method for internal stuff

[lilac sandal]

If you had only few days to built a quick and dirty installer without any diffing or update feature, what would you use?

[mint leaf]

Itch

can be done in 15 minutes

[lilac sandal]

Ah wow, then I will definitely use that 😁

[mint leaf]

Functionally

# Login to butler
.\butler login

# Upload the data
.\butler push "$FILE_PATH" "$ITCH_CHANNEL"

# Logout of Butler for Security
.\butler logout

Youll need to set some env vars but beyond that it works

[mellow bane]

Basically not using Butler is crazy, so use that, and then you have a choice of using itch.io + its client, or creating a simple frontend for Butler yourself - batch file etc

[lilac sandal]

Wow, it seems really straightforward

Is it possible to create a simple .exe of a Powershell script? Because most systems cannot execute it without remote-signed permission

[mint leaf]

thats to upload the files to butler

user can then download via itchs client

[lilac sandal]

Ah ok, I understand

[mint leaf]

Also powershell on remote systems is trivial to bypass 😄

But thats a conversation for another day

[lilac sandal]

Ahahah ok

Thank you for all the tips

[hollow iron]

My project finishes packaging without errors/issue, but when I try to launch the .exe I just get a small window that says "Fatal Error". No further information. I've perused the log and no obvious issues stand out to me. The project runs fine when I just right click the .uproject file and Launch. What could be causing this issue?

[lavish lodge]

Hi, is any option for packaging project and include only assets with reference ?

[mint leaf]

package in development, not shipping

[hollow iron]

I've tried both development and DebugGame - same result

[fierce shadow]

I want to package to windows and i have VSCode installed, but it says i need Visual Studio. Is there a way to get around this?

[runic stump]

No. You need visual studio compiler & windows sdk in order to build ue for windows.

[fierce shadow]

k thanks

[tepid bone]

Hey , does someone know why certain actors wouldn't show up in a packaged build? Specifically Decals. I checked the obvious and made sure that "Is Editor Only Actor" was unchecked.

[cursive kindle]

If you’re not worried about people taking your assets, what are the advantages of Pak files?

And what about having a single pak vs several

[mellow bane]

People will take your assets no matter what, fi they want to . Paks are faster to load ; single pak slower to update

[mellow bane]

Material failing to compile at packaging, possibly

[tepid bone]

No errors on the material. I'll try deleting my cache and see if that fixes it. Thanks

[mellow bane]

Check the detailed packaging log files under appdata somewhere - there's a file that lists everything being packaged

[cursive kindle]

Is there any data on the internet that shows this? Has anyone ran any tests?

[mellow bane]

IO speeds being much higher for large sets of continuous data is a pretty universal thing

Usually you're loading a lot more than one asset, so you're going to read maybe 50 textures from the disk - there's no filesystem where a pak file won't be faster

Pak files can also be optimized to provide the ideal ordering of files for your game

[cursive kindle]

And what about having 1 pak vs a few? Why is it slower to update? And what’s the max size you should have per pak

[mellow bane]

If you need to remove one byte at the beginning of a 50GB pak file, there's no way to do that without rewriting the remaining 49.99GB

[cursive kindle]

How is that ordering determined? How is that optimization achieved?

[mellow bane]

https://docs.unrealengine.com/4.26/en-US/Basics/Projects/Packaging/

[cursive kindle]

Nice

Thanks!

[mint leaf]

not sure, id have to go digging beyond that

[lilac sandal]

Hi, I have a new question about dependency installation. I want to build a seamless Win64 installer for users, in your experience does UE4PrereqSetup_x64 actually install every needed prerequisite on any system or there may be some cases in which it fails?

[mellow bane]

Re-posting that question from a few days ago :

Did anyone got primary asset labels to work for designating chunks for content, as of 4.26 ? Levels work fine, but primary asset labels appear to be completely unable to mark general assets for chunks.

[mint leaf]

its on my to look at list, buit will be a decent period of time

[hollow iron]

Update on my Fatal Error on launch problem - Still having the issue. I've tried packaging in Development and DebugGame. Both result in the "Fatal Error" window on lauching the .exe. The game runs as desired in standalone - no errors in the packaging output log. I've tried disabling antivirus software, updating drivers, verified my UE4 install, and some other things I can't think of right now. Double-checked my visual studio setup. At this point I'm running out of ideas and it's frustrating that Epic is basically unreachable for issues like this.

[lilac sandal]

Have you tried to compile all blueprints in isolation?
/path/to/UE4Editor /path/to/your/project.uproject -run=CompileAllBlueprints

Look at all these tips that they gave me in the Linux channel, I think they can be used even on Windows: #linux message

[tepid bone]

yeah it says that the material is getting packaged / or at least it's listed in there

[runic stump]

disks show better performance with fewer but bigger files rather than more but smaller ones. this is especially true for rotational hdds.

[cursive kindle]

But then with 1 big one you suffer from having to update the whole pak when a small thing changes, so where’s the balance?

5gb paks max?

[runic stump]

I'm not sure, to be honest. Even the crappiest rotational hdds can linearly read up to 50-100mb/s. And can linearly write 20-40mb/s. It's random i/o what kills their performance.

I'd target at about 1-2gb per pak.

though it depends on total game size. the bigger the game, the larger paks would tend to be. you likely don't want to have 500 pak files, for example.

[fierce shadow]

When i click package for windows, it opens this website :https://docs.unrealengine.com/4.26/en-US/Tutorial/Installation/InstallingVisualStudioTutorial.InstallingVisualStudioTutorial but its just a 404 error. How do i get it to actually package my project?

[hazy goblet]

Hey guys I am trying use blueprint nativization, for some blueprints using a oculus source engine 4.26.2 ..
But while packging it is giving me error, and the stack trace is this.

[cursive kindle]

Thanks man

[hollow iron]

I haven't tried that! I'll give it a shot. Thank you!

[craggy cobalt]

tbh I'm not going to fish the error out of a big log. log is helpful but it would be best if you pointed out the part of it that's bad

relevant bit seems to be

[hazy goblet]

@craggy cobalt is it possible to nativize game instance ?

[sour flume]

how can i fix this problem ?
engine version : 4.26.2 source compiled
sdk , ndk , jdk installed !

[runic stump]

FYI: nativization was removed in UE5. So if you plan to upgrade, it isn't worth fixing.

[winged moss]

that's quite a surprise, it helped tremendously with ABP performance

[mint leaf]

install VS with correct components

[fierce shadow]

thanks i got it

[tepid sand]

Running into a really weird problem.
We got a couple of materials in nice hierarchies, master material. All the good stuff.
A couple of our materials don't need all the features in the master mat.
So we put in a tiny, white texture to zero it out basically.
All of that works excellently.

But when packaging, it ignores the texture and reverts to the master material default and I just can not figure out why!

What it should look like:

Packaged

The texture that's ignored:

[tepid sand]

Uff. Thanks rubber duck channel!
I was being a dum dum as always.
Texture was from engine content. Specifically the landscape textures.
Landscape plugin disabled to decrease build size. Texture obviously doesn't exist anymore.
Making a copy for our content folder fixed it.

[sour flume]

Does anyone know what could be causing this? My packaged project is crashing on startup

[sinful fog]

Copy pasting from #plugin-dev since I'm not sure where this relates
Hi friendos,
I've managed to include FFMPEG in my project as a third party
It all works inside the editor and I'm able to include and use it's libraries
BUT when calling any of it's functionalities crashes my game when packacged.

Does anyone know what could cause this issue?

Here's my Build.cs file

[mellow bane]

Well, debug the crash

[sinful fog]

How did I not think about that

For real now, how?

[mellow bane]

Either open the packaged exe in VS and click "debug", or open the minidump in the crash folder and hit "debug"

(That'd be the debug button that will appear in the file editor for either file, not the top level one)

[sinful fog]

But the error is in the linking of the libs, I think.
I know what function is causing the crash already

I just dont understand why it only happens in the packaged build

[sinful fog]

Also, where should the crash folder be? I can't seem to find one

[mellow bane]

%LOCALAPPDATA%/GameName/Saved/Crashes

[sinful fog]

On it!

No crash data there 😦

[mellow bane]

Just debug the executable directly then

[sinful fog]

Here we go

Ok, so I've opened it through vs and crashed it, but the log shows no information

[mellow bane]

There's no log in shipping

There's a call stack though

[sinful fog]

nothing there too

[mellow bane]

Define nothing

[sinful fog]

Voidness

[mellow bane]

Game hasn't crashed yet, click the ok button first

Or pause in the debugger

[sinful fog]

Now the call stack window disappears

Error list is empty too and output shows this:

[mellow bane]

THe call stack is the only thing that matters here

[sinful fog]

pausing it did the thing though

ntdll.dll!00007ffc3a98cea4() Unknown
KernelBase.dll!00007ffc381219ce() Unknown
FB_RENDERER.exe!00007ff635d118c5() Unknown

kernel32.dll!00007ffc3a6e7034() Unknown
ntdll.dll!00007ffc3a942651() Unknown

[mellow bane]

It sounds like you don't really have a crash here, but an error that forces the game to close without crashing

Make sure your code doesn't have anything like that

[sinful fog]

I did not write anything like that, for sure

AVFormatContext* pFormatCtx = avformat_alloc_context();
if (avformat_open_input(&pFormatCtx, file, NULL, NULL) < 0) return tcData;

these two lines cause the crash, If I remove them everything works fine (except the fuctionality of the program)

[mellow bane]

Make sure the DLLs are correctly copied to the packaged game

And of course make sure that code is correct

[sinful fog]

I know they are not, That's why I started with the Build.cs
But I dont really understand whats going on there

[sinful fog]

It does what I ask it to

[mellow bane]

Add some logs to your build.cs to understand what goes wrong : https://answers.unrealengine.com/questions/523749/logging-from-buildcs.html

[sinful fog]

Will do

oh wait, where would they show up?

[mellow bane]

Should show up during packaging

[sinful fog]

Ok thanks

Printing it's stuff shows that UBT is copying the dlls located in the ThirdParty folder to the Binaries folder

The dlls are NOT located in the binaries folder of the packaged project.
Also, placing them there manually does not solve the crash.

Do you know where they are supposed to be in a packaged project?

[mellow bane]

Probably Gamename/Binaries/PlatformName

[sinful fog]

Ok got it!
Not ALL files are copied into the Binaries folder of the packaged game

Which is HILARIOUS because the only file that IS copied is not included in the c# code I wrote

[sinful fog]

Something weird is happening.
I'm logging the process to see:
what is copied, where to, and from where.

Logs show the copying is correct, but they relate to my project directory and not the package directory

[runic stump]

You don't need to do any copying by hand. Just use RuntimeDependencies.Add(...); in build.cs.

[sinful fog]

I'm already using it though

//Go over all dlls in the ThirdParty folder
            foreach (string dll in dlls)
            {
                PublicDelayLoadDLLs.Add(dll);
                
                string CopyPath = Path.Combine(DllPath, dll); //..\..\FB_RENDERER\ThirdParty\ffmpeg\bin\vs\x64\filename.dll
                CopyToBinaries(CopyPath, Target);
                
                RuntimeDependencies.Add(Path.Combine(DllPath, dll), StagedFileType.NonUFS);
                Log.TraceInformation("Library Added: " + Path.Combine(DllPath, dll));
            }```

[runic stump]

..\..\ FB_RENDERER\ThirdParty\ffmpeg\bin\vs\x64\filename.dll
And in what dir do you expect ue to put this file?

Where is that ..\..\ supposed to point to?

[sinful fog]

here
Path.GetFullPath(Path.Combine(ModuleDirectory, "../../Binaries/"))

[sinful fog]

😅 it's just a comment
I'm trying to make some sense in all this idrectory hell

[sinful fog]

Btw, this works in the editor

[runic stump]

Just look how unreal uses RuntimeDependencies itself. For example,
Engine/Plugins/Experimental/AlembicImporter/Source/ThirdParty/Alembic/AlembicLib.Build.cs: RuntimeDependencies.Add("$(BinaryOutputDir)/zlibd1.dll", "$(ModuleDir)/Binaries/Win64/zlibd1.dll", StagedFileType.NonUFS);

It says where and what to put during packaging. And ue does the job.

[sinful fog]

"$(ModuleDir)/Binaries/Win64/zlibd1.dll", StagedFileType.NonUFS);
Where does it say here where to put it?

[runic stump]

No idea, need to look into UBT source.

3-arg method is more explicit

[sinful fog]

🤒

what's the 3 arg method?

[runic stump]

Engine/Plugins/Experimental/AlembicImporter/Source/ThirdParty/Alembic/AlembicLib.Build.cs: RuntimeDependencies.Add("$(BinaryOutputDir)/zlibd1.dll", "$(ModuleDir)/Binaries/Win64/zlibd1.dll", StagedFileType.NonUFS);

[sinful fog]

I don't get it...

[runic stump]

drink some coffee 🤷‍♂️

[sinful fog]

That's a solid advice 🤣

[runic stump]

RuntimeDependencies.Add("WHERE", "WHAT", StagedFileType.NonUFS);

[sinful fog]

@runic stump An angel ♥

[runic stump]

And there's some fancy macro expansion on top of this. Somehow ue understands what does $(BinaryOutputDir) mean after all. I'm not sure where to get the list of all available $(...) things.

[sinful fog]

Yeah I also could not find it...
Probably some voodoo magic or something

[runic stump]

some voodoo magic
No, just a piece of C#: https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Source/Programs/UnrealBuildTool/Configuration/UEBuildModule.cs#L614-L655

I'm getting this issue on packaging a dev build (google doesn't say much that helps)

the code being the following

[knotty valve]

so I found out why... and it's crashing here: cpp SkyboxActor = GetWorld()->SpawnActor<ABBzLevelSkyboxActor>(SkyBoxClass, TempTransform, SpawnParameters);

This is the last call in my code that runs before failing on that. Though not exactly sure why. The Skybox Actor has the following in C++ ```cpp UPROPERTY(VisibleAnywhere)
USceneComponent* PivotComponent = nullptr;

UPROPERTY(EditAnywhere, BlueprintReadOnly)
TArray<FLinearColor> AvailableColors = { FLinearColor::Blue };

UPROPERTY(BlueprintReadOnly)
FVector RandomRotateVector = FVector::ZeroVector;

UPROPERTY(EditAnywhere, BlueprintReadOnly)
bool bRotatePivotOnTick = true;

UPROPERTY(EditAnywhere, BlueprintReadOnly)
FVector2D RotatePivotRange = FVector2D(-0.001f, 0.001f);```  and the BP class has the additional data

[mellow bane]

What year is it

Well, okay, I just never saw a game install that way since the 1990s

I guess innosetup is fine

You just need to prompt for a folder and copy the game there, and run the redists

So it's not rocket science

I wonder if Butler can't do that too

Failing that, a Qt window with a few buttons can be slapped around in days and compiled statically (requires source code publishing)

[runic stump]

I think wix won't work. Windows keeps copies of all installed .msi files. I forgot which dir it is exactly. That effectively doubles disk usage. With game sizes, that just not going to work.

[mint leaf]

nsis is great once you learn the quirks and script it

because its really easy to build into CI

[runic stump]

It is either C:\ProgramData\PackageCache or C:\Windows\Installer. Most likely the latter. The former keeps copies of all Visual Studio modules.

[mint leaf]

Ive used nsis and installshield and I much prefer NSIS, also its OS ❤️

[knotty valve]

I absolutely love Inno. Used to use it for completely legal repacks back in the megaupload days, and the customization and scripts that you could do where rather nice

A bit out dated though, but a personal preference

[runic stump]

Well, I haven't seen optical disks for over a decade, but even the latest consoles generation still uses them. So... It looks like time doesn't fly everywhere with the same speed :D

[crisp patrol]

What is stopping users from buying your game on steam, copying the game files to another directory, then refunding the game and still being able to play the copied version?

Do you need to add Steam checks at launch in order to prevent this?

If so are there any tutorials on the subject?

Looks like this is the answer but if anyone has other methods please ping me: https://partner.steamgames.com/doc/features/drm

[knotty valve]

@crisp patrol without cracked/patched DLLs, some games get around this by adding authentication to their games on startup / load of elements

you use the auth functions to first:

• check that you have a steam account and are logged in
• check that that account owns the game

ofc patching those default dlls is somewhat simple, and back when game piracy was in its peak, you had multiple online groups releasing them left and right, such as SkiDrow and Reloaded

[knotty valve]

if anyone has any info on why this might be happening, I'll greatly appreciate it! I've narrowed it down to one actor, but have yet to understand why the loading for these assets (textures and materials) is failing for packaged. Loading them synchronously at the blueprint state through CDO variables

[mint leaf]

You cant really stop game piracy, people who gonna pirate are gonna pirate. You could look into something like Denuvo, but all that achieves is making it worse for your regular users

Denuvo has been cracked already and causes framedrops and other performance issues

its only really "worth" it for a short period after launch

@crisp patrol ^^

[craggy cobalt]

debatable even then

[craggy cobalt]

hotreload? 😛

[knotty valve]

you're asking me that

me

[craggy cobalt]

heheheheheh

well if there is a blueprint involved on the skybox then it wouldnt hurt to make a new one- i dont know how many devs are on your team

but maybe thats too much effort to be worth it /shrug

if theres not one, well...

there just has to be something different about how its being set up, probably in C++ land rather than placement in level

[gilded yew]

anyone know why my packaging keeps failing?
PackagingResults: Error: Unable to rename C:\Users\wret\OneDrive\Documents\Unreal Projects\Extinction\Intermediate\Build\Win64\Extinction\Development\Core\SharedPCH.Core.h.txt.tmp to C:\Users\wret\OneDrive\Documents\Unreal Projects\Extinction\Intermediate\Build\Win64\Extinction\Development\Core\SharedPCH.Core.h.txt

[knotty valve]

I have 18 skybox children bps tho

hahaha

[mint leaf]

I dont disagree, but if some devs want to layer 5 copy protectoins on their game thats their business

[knotty valve]

and then be like Sims World where pirating the game was an easier way of being able to play than by having a legit copy

[gilded yew]

is anybody aware on how i can package my game

[mint leaf]

yup, Id say its pretty proven that anti piracy doesnt really work at this point. What works is making your game easy to get legally and priced sensibly

[mint leaf]

Package Project?

[knotty valve]

what have you tried from googling it?

Just so we know at what stage of troubleshooting you're at

[mint leaf]

That said that error looks like r/w perms, delete intermediate and recook/compile is probably a good start

[mint leaf]

[gilded yew]

im getting an error everytime saying
PackagingResults: Error: Unable to rename C:\Users\wret\OneDrive\Documents\Unreal Projects\Extinction\Intermediate\Build\Win64\Extinction\Development\Core\SharedPCH.Core.h.txt.tmp to C:\Users\wret\OneDrive\Documents\Unreal Projects\Extinction\Intermediate\Build\Win64\Extinction\Development\Core\SharedPCH.Core.h.txt

[mint leaf]

I mean you really shouldnt have your game in one drive to package

[knotty valve]

and have you googled it already

[mint leaf]

but thats a different story

[craggy cobalt]

ugh if it turns out to be hotreload I pity the fool dev who gets the blame on bisect

[mellow bane]

Try packaging outside your OneDrive folder.

[gilded yew]

ok

[mint leaf]

and please for the love of all that is holy look into proper source control

[craggy cobalt]

heheh

[knotty valve]

Wait... don't tell me that you're using that OD folder as the source control

[mint leaf]

Yes, yes he is

[craggy cobalt]

onedrive barely works for regular stuff

I mean it's not specific to OD though

[gilded yew]

i think my project files are in onedrive

[mellow bane]

That's likely not a great idea

[knotty valve]

github private repositories are free

[craggy cobalt]

well yeah they clearly are

[knotty valve]

why are you on OD for this

[gilded yew]

can i move it easily?

[mint leaf]

eh azure devops is probably better tbh

[knotty valve]

Github -> Create Repo
Local -> Clone that Repo
Paste your project into your Git thing
Upload and profit (commit limit is 4gb tho; divide your commits)

true

though let's not run before we can walk

[mint leaf]

github has a 1gb? limit iirc (on lfs)

so its very hard to recommend

[knotty valve]

their hard limit is 100gb

[gilded yew]

my project is about a gig

[knotty valve]

no, LFS is for single files larger than 100mb

[mint leaf]

Every account using Git Large File Storage receives 1 GB of free storage and 1 GB a month of free bandwidth. If the bandwidth and storage quotas are not enough, you can choose to purchase an additional quota for Git LFS.

[craggy cobalt]

this is all well and good but if you didn't even intend to use OD to back up your project then yeah just get it out of OD and see where you're at. You're going to want to delete intermediate etc after you copy it out too

[gilded yew]

wait so should i be using github or not?

[mellow bane]

#source-control

[craggy cobalt]

you should be, for version control on your project, but if you are just learning stuff then it's not the biggest deal.

[gilded yew]

i just wanna send my mate a copy of the game

[craggy cobalt]

to edit it or to play it?

[gilded yew]

play

[craggy cobalt]

you don't need onedrive for that, just package it

so just get it out of OD :-)

[gilded yew]

it crashes on onedrive

i get an error msg

and the source files are on my onedrive

[craggy cobalt]

yeah because onedrive is hooked into the filesystem, copy it out of onedrive.......

[gilded yew]

this is the error

whoops

[mellow bane]

• Move the project folder outside of OD
• Remove the Intermediate folder
• Try again

[gilded yew]

the WHOLE project?

[mellow bane]

Yes

[knotty valve]

move the project out of OD [yes, I'm tired]

[gilded yew]

ok

[mellow bane]

The error here is while compiling so the project location is the issue

[craggy cobalt]

honestly you probably don't need to delete any build files or anything after copying it out

the above error is clearly just OD interference

[mint leaf]

sure, but the amount of tiny files is likely to take a month

[craggy cobalt]

no, it's locally available, it will take the same time as making a local copy of the project

which is not nothing, but not any more than any other folder

[mint leaf]

sure, but its likely to hammer his SSD

[craggy cobalt]

I could be wrong if they have this on another machine but seems that's not actually the case

[gilded yew]

thx seems to be working, but dont wanna count my chickens before they hatch

[craggy cobalt]

yep

[gilded yew]

i just drag moved my project folder

also what does cooking my project do?

[craggy cobalt]

it creates optimized production only versions of your assets

[knotty valve]

^ though unless you have bFullRebuild = off in packaging settings, it won't really matter

[gilded yew]

should i be doing it before every export?

[craggy cobalt]

no

[gilded yew]

ok

[craggy cobalt]

package will take care of that

[gilded yew]

yh just looked in the console and it says just that xD

[mellow bane]

Cooking is a mandatory and automatic step of packaging, non-editor game is simply unable to load uncooked content

[craggy cobalt]

yep

yeah luckily its cached upon successful build

if this is your first packaging, dont expect every subsequent package to take that long

[mint leaf]

The automatic is abit debateable when you get bigger, but I dont disagree in general

[gilded yew]

also is their anyway to make the exported game NOT require C++?

[mellow bane]

Sure

[mint leaf]

Im always leery of using iterative packaging

especially in CI

[mellow bane]

Don't use any, in plugins or game, and don't enable nativization

[craggy cobalt]

absolutely, but for a one-man learning dev to share a packaged game its ok

[gilded yew]

thnk u

[craggy cobalt]

would not do it for CI necessarily

[mint leaf]

even then, it tends to break

[craggy cobalt]

it definitely can

[mint leaf]

Not worth the amount of hours trying to debug weird shit

[craggy cobalt]

ehh i dunno it really depends how important it is- takeaway would be "hey, weird shit is happening, maybe do a fresh cook"

at least at a small scale

[gilded yew]

is it easy to switch to opengl instead of directx?

[mint leaf]

Just full rebuild and go make a coffee 🙂

[mint leaf]

its 2021?

[gilded yew]

school computer

no directx

[mellow bane]

What's OpenGL

"No DirectX" is not a thing

[gilded yew]

and packagng failed

[craggy cobalt]

you mean s/opengl/vulkan

[mellow bane]

Any Windows machine has DirectX available, the issue isn't that

[mint leaf]

it gives you a helpful error

[gilded yew]

but school computers are locked without directx

[mellow bane]

You have a corrupt texture in your content, according to the log.

[gilded yew]

bruh

[mellow bane]

Then you can't use them

[gilded yew]

i have a guess what it is

just delete ?

[mellow bane]

I guess

[mint leaf]

or fix it

[craggy cobalt]

if you havent modified the InfinityBladeEffects package, just reinstall it via* EGS

[mint leaf]

As to the question, its possible yes, but non trivial as in a lot of cases it stops you using certain material functions etc

in the project settings there is a render interface dropdown IIRC

[mellow bane]

If DirectX is "locked down" I doubt Vulkan will magically work instead

[gilded yew]

oh ok 😦

ue4 crashed

soon as i opened the folder with corrupt file in

[mellow bane]

Just remove it in explorer

[gilded yew]

ok

i pray it works now

[mint leaf]

it will likely crash due to missing texture reference

[gilded yew]

btw whats the best way of transferring the finished project

bruh

[mellow bane]

Steam

[mint leaf]

zip the folder, stick on USB drive

profit

[mellow bane]

Or itch.io

[mint leaf]

or itch works well

[gilded yew]

ok thx

praise be it has worked

thjnk u ALL so much ❤️

[craggy cobalt]

once the game is packaged, ship the resulting folder (with all files and folders within it) as you wish

[gilded yew]

tnks bro all good now 🙂

[open rapids]

Can i rename the exe file after package with out running into issues?

[craggy cobalt]

ehhhh maybe

if it starts then fine

if it doesnt then no

its as simple as that @open rapids

[mint leaf]

There is a setting to change the game name somewhere

[craggy cobalt]

yes but in a c++ project it's more complicated

[mellow bane]

In a C++ project you basically need to rename the project

[craggy cobalt]

its not fun

i have literally avoided it, so my EXE is the template i started with 😕

technically its just renaming the main module of your game, but the dependencies are complex, epic's own guide has tons of steps to make sure everything's covered

[runic stump]

You don't need to rename game module in order to change exe name.

[open rapids]

i see. thanks. I just changed exe file name after i packaged it and seems to work sofar ^^

[runic stump]

What you really need is to:

1. Rename .uproject
2. Rename *.Target.cs (and fix class name inside)
   And that's actually the end.

[craggy cobalt]

oh thats fair, since the target is referencing the module you could leave that as is and just set the target

nice

[runic stump]

And yep, it is funny that ARK: Survival Evolved exe is called "ShooterGame.exe" 😄

[craggy cobalt]

hehehe

[gritty helm]

Those texture names (Texture2D_999) look as if they're runtime-generated and not on-disk assets. Are you sure you're not trying to cook infinite number of textures?

[gritty helm]

not sure how to check it, whatever designers committed into repo

[runic stump]

That's what I am talking about. If you have infinite number of textures, you might need infinite amount of RAM and will definitely need infinite amount of time to cook that.

[craggy cobalt]

infinite ram, ez

[gritty helm]

i wonder how they broke it

[runic stump]

Completely. They broke it completely. 😄

[gritty helm]

have to have a working packaged build by tonight and everything is

[runic stump]

Well, maybe it isn't infinite but just very huge.

[runic stump]

Just revert problematic commit 🤷

[gritty helm]

the problem is how to find one out of four hundred made in past week

😄

[runic stump]

Well, you are just going a painful route to understanding the usefulness of regular CI builds 😄

[gritty helm]

i had CI in almost all of projects so far, but not on this

[gritty helm]

all hail PackagesPerGC=128

[knotty valve]

ah... Solo projects.

[mortal cape]

Hi I create a video play in widget method it's working perfectly in pc but the problem is when I export to android it's black screen appears
please any one give me the solution
I am searching for this 2 weeks but can't find anything useful please help me

[craggy cobalt]

when you say "working perfectly in pc" i assume you mean Play in Editor or Standalone. If you were to package it for PC it would be broke too. It sounds like your video files is not seen as used by the editor, which means its not including it in a packaged build. Try moving your video to the "Movies" folder, which is special and is always packaged, or add the folder containing the video file to the "Additional Asset Directories to Cook" list in Project Settings- or reference your video asset a different way which triggers the engine to know that its referenced

[sonic trellis]

Hey guys i am getting some errors on my packaging and it fails everytime i try to package my project

here is the log file

pls help me out someone

[mortal cape]

@craggy cobalt ok I will check thanks for the information
