Where does the source of Content/Editor/Templates come from?

After I build a source version of UE, I can edit the default templates inside that folder. But I want to source control those templates with some changes, and it doesnt seem to be in the source code itself? Is that pulled from somewhere via the setup.bat and we dont have control over that (other than replacing post install)?

They are uassets, and if you're acquiring source from GitHub they'd be part of running setup.bat

#

Also depending on what source control you use and how you branch, that's not much of an issue if you have the engine versioned

#

The use case for modifying an engine asset is a little questionable

#

hidden hedge The use case for modifying an engine asset is a little questionable

I like to change the default c++ templates, so that they dont have all the comments, set tick to false etc. So each time I create a new c++ class, it is preset how I want.

#

it works perfectly, just need to make sure it stays as I upgrade

hidden hedge Aug 17, 2023, 2:13 AM

#

Huh? What "templates" are even in this folder?

south vortex Aug 17, 2023, 2:13 AM

#

like when you make a new Pawn.cpp file

#

the text that exists in the file

#

i.e. a new class

#

That is all customisable via the template folder.

#

So I like to remove all the "comments" from the files etc and setup a few things I use on every c++ file (such as GetLifetimeReplicatedProps() etc)

#

hidden hedge Aug 17, 2023, 2:16 AM

#

Since they're text then they might actually be pre-setup.bat. the engine will have a content directory the same way a project would

#

Though that's kinda the thing that code review would catch. I would have to take a look at the logic on my PC to see if you can override rather than replace

thats what I thought too - but I cant find it in Github on the source prior to installation

#

which brings me to the original question - where does it come from

hidden hedge Aug 17, 2023, 2:18 AM

#

Epic's CDN when you run Setup.bat it is then

south vortex Aug 17, 2023, 2:19 AM

#

ok... so we cant change it pre, just need to source control it seperately then?

#

thanks

hidden hedge Aug 17, 2023, 2:20 AM

#

I guess if you can't do a project-level override then yes, but at least with Perforce I've always had a "clean" engine depot which gets merged to the project's copy of the engine

#

Then at least you get a merge conflict if Epic updates the template

Greets Ehab. Did you ever solve where to get the boost files from?

gloomy stone Aug 17, 2023, 1:17 PM

#

You can fix the issue by deleting the holosens folder in the directory "\Engine\Source\Programs\Holosense"

Then open the Engine Source Build and remove the holosens from the programs explorer on the left hand side.

Then build the Automation Tool first and rebuild the whole source build after cleaning.

Hey guys sorry for the probably stupid question. I'm currently trying to build unreal engine 5 from source through the latest sources provided, the 5.2.1 release on github.
It gives me these errors you can see in the picture. Ther first two files are actually there but can not be opened, but there is also no intermediate folder in the visual studio project file do I need to add that maybe? I tried it but that didnt seem to help.

The C1083 errors might be the result of the D8022 errors but I cant be certain, the files it is searching for are definitely not created though.

Could you guys tell me how to fix these and or what I could at least try? I was thinking of completly disabling these plugins since I do not want to build for mobile platforms or want to have any midi signals (which seem to be the purposes of these plugins). But is that even a valid aproach?

I'm trying to track down where/how UPROPERTY are loaded into the engine. I know they are macros in the UHT prior to compile, but obviously what they are changed into is eventually loaded into C++ somewhere since the data is used by the engine itself?

For my example, I want to override the default Category tag. Currently if you do not set a Category name, it will default to the object name as the category name. I cant seem to work out where this occurs?

Hello sorry if this isn't the correct channel to post this in however is there any chance someone knows what is causing this error? I've been trying to build Unreal Engine from source for a while now with no success. I've followed both
https://docs.unrealengine.com/5.2/en-US/downloading-unreal-engine-source-code/
https://docs.unrealengine.com/5.2/en-US/building-unreal-engine-from-source/
However when my build ends I end up with the following error
I've tried just running this command myself and I get this error (I did realize that I was trying to use UE4Editor as an argument and replaced it with UnrealEditor which seemed to allow it to run correctly not sure why my Visual Studio is running it incorrectly, though when it runs in visual studio with the new target it doesn't seem to run at all and fails with a MSB3073 exited with code 6)

Sorry if this is an obvious issue I've tried searching about it but can't seem to find out what is causing it. The main reason I wanted to build from source is to my knowledge its a requirement for learning/making dedicated server games.
https://docs.unrealengine.com/5.2/en-US/setting-up-dedicated-servers-in-unreal-engine/

If this is the wrong channel let me know and I'll move the post to there

This is a clean install from GitHub the only thing on this drive is Unreal Engine unless there is possibly remaining files on other drives that are being shared with all installs as I have installed unreal engine from epic games on a completely seperate drive.

The error seems to be

CompilationResultException: Error: OtherCompilationError

from the UnrealBuildTools log. I've found that there can be multiple build configuration locations and I had some from previous engines in

<USER>/AppData/Roaming/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml
My Documents/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml

So I have removed them in case they're causing possible conflicts?

If there is a way to clear anything from a previous engine that may have conflicts or other files I have no problems doing that and then trying to reinstall from source again with newly installed tools. So far I've tried clean installing from source multiple times updating Visual Studio and Visual Build Tools and now removing these shared build configuration

echo hatch Aug 20, 2023, 7:31 PM

Hey guys I'm trying ot build an unreal engine server for linux arm64 on windows 10 and I'm getting the error:
invalid sh_type for clang++
Several times which makes the packaging fail at the last step.

hey there, is someone up to date about the Optimizations made in the 5.3 branch (? I'm porting some back to custom 5.2.1, already ported some volumetric cloud optimization's)

Really confused on what my ApiUrl should look like for UGS

#

Should it be local to the server?

hidden hedge Aug 28, 2023, 1:28 AM

#

opal gorge Should it be local to the server?

"local to the server"?

#

it should point to metadata server, as a URL, each client with UGS installed will hit this endpoint

opal gorge Aug 28, 2023, 1:34 AM

#

Got it, thanks for the clarification

#

Also, looks like UGS requires a Windows Server? Guessing I can’t run in on a Linux machine? IIS is only Windows from what I can tell. ASP .Net should be able to be installed on a Linux server.

hidden hedge Aug 28, 2023, 1:38 AM

#

the one in the official repo does, but there's a fork that runs on .NET 6

#

https://github.com/sswires/UnrealGameSync/ this is my fork of a fork, it's what I ended up deploying

#

I might try and do an open source replacement since this fork (and the one it's based on) might break the Unreal EULA, but oh well

opal gorge Aug 28, 2023, 1:45 AM

#

Interesting. I’ll have to go through and check it out. Would be super nice to have UGS run on a Linux instance for us.

hidden hedge Aug 28, 2023, 1:50 AM

#

that's what I ended up doing after miraculously finding the fork, I updated it to .NET 6 as that's an LTS release

Pretty cool. Looks like you've made some other changes as well. I'll see if I can get this deployed properly on CentOS

In order to get Steam working properly in editor (e.g. launching with -game cmd) I had to add this to my MyProjectEditor.Target.cs

bOverrideBuildEnvironment = true;
GlobalDefinitions.Add("UE_PROJECT_STEAMGAMEDIR=\"myproject\"");

This works great, but now after running GenerateProjectFiles.bat, when I build the project in VS it rebuilds the engine. Once this is done it's fine until I run GenerateProjectFiles again.
Before modifying the Target.cs it was fine.
I'm guessing something to do with the bOverrideBuildEnvironment param, but the same param for Game/Server build etc does not cause rebuild.

I have tried deleting my Intermediate folders but the problem just comes back.

Anyone got any ideas before I give up and remove the change to the Target.cs ?

hidden hedge Aug 28, 2023, 7:15 AM

#

making a change like this will invalidate your engine build, yeah

#

not sure why you need to do it to the editor target though

calm mason Aug 28, 2023, 7:16 AM

#

Yeah I can understand it invalidating it once. But then GenerateProjectfiles causes it to invalidate again, each time I run it

#

As for why I need to do it, if UE_PROJECT_STEAMGAMEDIR is not set correctly in the Editor target, I cannot test Steam without doing a packaged build.
It's an inconvenience, but not as inconvenient as having to rebuild the project every day.

Setting up UGS with Linux seems a little harry :/ may have to use a windows server barfs

calm mason Aug 28, 2023, 8:01 AM

#

You know you don't NEED the metadata server to use UGS? It's a nice to have feature.

opal gorge Aug 28, 2023, 8:05 AM

#

Yeah a lot of functionality is lost without it

#

Guess it doesn't matter as I can't even get AutomationTool.P4Connection.GetClientInfoInternal to work

opal gorge Aug 29, 2023, 1:11 PM

Removing -set:EditorTarget defaults the value to -set:EditorTarget=UnrealEditor

The first question was clear enough

iron dome Sep 6, 2023, 6:46 PM

#

What I'm saying is, to start the editor, you don't ahve to build the entire thing. There are a lot of extraneous shit in the solution that isn't needed.

#

And if you have errors compiling it, it really makes no difference.

#

So start the UE5 project and see if that will compile/run, instead of building the entire solution .

#

did you check out the latest in the release branch?

#

Or did you check out a specific tag (the 5.3 release tag) ?

onyx light Sep 6, 2023, 6:54 PM

#

i just made a new branch in github desktop based on upstream/release

#

and that was updated 5 hours ago, when 5.3 came out

iron dome Sep 6, 2023, 6:55 PM

#

Git is frequently broken. You should check out the specific 5.3 tag.

#

Not branch, tag.

#

And make sure you run the setup.bat file too

onyx light Sep 6, 2023, 6:58 PM

#

the setup.bat file is a year old so it hasnt changed since I last ran it but I guess I'll try that

onyx light Sep 6, 2023, 7:25 PM

#

rerunning the setup didnt change anything and i dont see anything in github desktop about tags

#

i think im just gonna wait a day or two to see if anyone else runs into this because there's nothing on google or this discord about this error so I suspect that the problem might not be on my end vOv

thanks for the help tho man

Why does Epic tell you to install a Lyra project in the top-level directory of your custom engine build folder? If you want to create a git repo it is awkward to have a git repo inside of a parent git repo when it isn't a submodule

It's just a way to set up a project. You can just put it anywhere.

Question that I'm not entirely sure how to phrase, or maybe I'm just thinking of this the wrong way. I often have to dig through source code to see how things work, as I deal a lot with the editor and such. I know I can put down breakpoints in the code and debug to then hit those points, but is there a way I can see what is being called without having breakpoints and whatnot? Like see some sort of call trace when I click a button and see exactly what in the code is being called and executed so I can better figure out how to replicate functionalities. Does that make any sense?

honest burrow Sep 7, 2023, 4:33 AM

Do you know that you can proceed step by step line of codes when breakpoint hit?

#

honest burrow Do you know that you can proceed step by step line of codes when breakpoint hit?

Yeah, I know I can do normal debugging stuff like that. I'm more looking for an easier way to find out where something even starts. Often I'll find words or things that I can search the code for to find where, when pressing a button for example, that kicks off some code so I can then figure out what's going on.

Hello folks,

1)Engine compiling questions. MSbuild requires a massive 1.5GB per core to multithread compilation, but when running, the task manager indicates that I have at least 5GB of unused RAM at all time.
Can I reduce the 1.5GB requirement to something lower ? as the processes clearly do not use all that.

2)I only managed to use half my cores (3 out of 6) when closing everything but VS and compiling the engine from source takes at least 3 hours with this setup (which seems abnormal if the documentation is anything to go by).
I seem to be missing on a lot of available memory when starting the compilation (task manager reports more than 10GB free, MSBuild sees less than 5).
Am I missing some setting that would let me claim all the available RAM for compiling ?

iron dome Sep 8, 2023, 1:37 PM

#

You can, but it might cause problems. I have the limit disabled, but I have a shit ton of RAM. I max out at about 1.25GB/process.

#

3 processes taking 3 hours sounds abour right.

#

To disable the limit (and potentially screw yourself in some other way) you can cahnge your buildconfiguration.xml file

#

<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
    <ParallelExecutor>
        <MemoryPerActionBytes>0</MemoryPerActionBytes>
    </ParallelExecutor>

Tried deleting intermediate and the saved folder, now building the engine through visual studio again. I don't think this is correct is it? this would take me about 20 hours

iron dome Sep 10, 2023, 7:41 PM

#

That's correct.

#

Though you don't need to build all 6321 actions. It should be closer to 3500 actions.

#

So don't compile the entire project. Link your project to the source build and compile your project.

Hey, everyone. I've been in a bit of a difficult situation lately and I was hoping to ask for help.

I submitted my game to ID@Xbox a while ago, and unfortunately, they have been pushing me towards the Xbox Live Creator's Program instead. The big issue I've been running in to, though, is the fact that Xbox Live games reply entirely on UWP, something that UE has not supported since 2016.

Is there any, ANY way I can make this work? My project was made in Unreal 4.26, so downgrading is not an option. I need a way for an engine, 4.26 or higher to be able to export for UWP. Is this possible? Is there a way to take the source code of something like UWP and bring it to higher unreal versions? I know that someone got it working a while ago, with HTML running in 4.27, so I figured I might as well shoot my shot and ask

#

This servers kind of far on my server list so, if anyone replies, please make sure the @ is on, so I can see your message

Hey there everyone, not sure if this belongs here but:

I have a custom engine build I would like to push to private a private repo, either in Azure dev ops, or GitHub to share with some people.
Whenever I have used Git LFS to push to either of these providers, I get the ol' "Remote closed due to going over max size" (or something of that description).
Does anyone have any recommendations or have any suggestions on how to share their Custom engine builds with folks within their team via GIT? Or am I chasing a fairy tale?

iron dome Sep 13, 2023, 1:43 AM

#

Use perforce? 🙂

#

Then you'll get potential UGS integration, which is nice for sharing builds.

fierce sentinel Sep 13, 2023, 1:47 AM

#

iron dome Use perforce? 🙂

Hahah shoot - I knew this day would come eventually. I haven't really ever heard of UGS before now, although it looks pretty handy. Does perforce have any issues with large pushes like GIT? I am assuming it doesn't due to being designed for large binary files

iron dome Sep 13, 2023, 1:47 AM

Perforce has many, many issues.

But it may just work where git lfs fails.

jesus christ. i was wondering why unreal was 238 MB in a shipping build. tracked it down to the entire hecking Chromium engine being dragged along in the third party stuff.
Why??
Because I had the OnlineFramework plugin enabled, which apparently has a module which uses WebBrowser to handle Facebook logins. . .
I fiddled around with a source build, and stripped down that module to not depend on WebBrowser anymore, and managed to make a 23.8 MB build of the engine. Litterally a 10th the size.

It was not super clinical. Just removing the reference to WebSocket from the LoginFlow.Build.cs and commenting out all the lines in the two cpp files that used web browser classes. I also put 'bWithCEF3 = false' into my projects build cs but I'm not sure what effect if any that had.

vague peak Sep 15, 2023, 6:31 PM

#

Well I wouldn't exactly say that it did nothing. It did cause packaging to fail with an error about not being able to override the build environment. I was able to fix that by adding the 'bForceOverrideBuildEnvironment' or whatever it's called. I would have assumed that it matches up with the predefined WITH_CEF3 macro. Where do you get that it does nothing from?

This was done in a source build of 5.3 btw.

vague peak Sep 15, 2023, 9:35 PM

Explude. Haha, I like that. From what I see in the engine source the cef3 binaries are included by the WebBrowser engine module (which is different from the WebBrowser plugin with the same name). There is some additional code that is inside #if WITH_CEF3 blocks. I think that might be what bWithCEF3 is for.
As long as WebBrowser isn't being included in the build (either manually or implicitely via another module like in my case) then cef3 shouldn't be included. I'm testing more tonight in any case. I want to see how small of an engine build I can make.

Late to this, not to come across as rude, but I don't know if I can rely on this version of the engine. I've not seen proof of it even really existing, even though I was told by Rose at the start of the summer that I'd have it in my hands "in several days", so that's why I'm looking for other options right now

west dune Sep 15, 2023, 11:35 PM

Yea, they were saying random shit, there's a reason why they left.

I am the main person working on it. It was heavily delayed due to me having a horrible move right now. It'll get done, just haven't been able to delegate work properly for it

Gotcha, I'm glad to know there actually is progress going on with it then, I'm sure you can understand why i was so skeptical though. I do appreciate the transparency

west dune Sep 15, 2023, 11:41 PM

#

Yea, I understand. Hopefully by November I can work on it more. We have it at a point where the editor compiles and properly has settings for UWP as a platform. Just needs some packaging adjustments and actual real world tests

Yes, Kobo and MinoDab are working on it too, but they've been waiting so I can sign off on some changes that were made that break stuff like HoloLens lol

Gotcha okay

#

If they need a game example they could port, I recently took an older VR title of mine (amatuer-ish FNAF VR fangame i made when i was 16, still pretty good though lol) and made a version that works with gamepad and flatscreen, just to test the game out properly

#

Would it be alright if i maybe sent them my project files ,and they could use it as a good benchmark?

#

it's a pretty heavy game graphically compared to my newer stuff, and the filesize is pretty big too so it'd be a good way to test a fully completed game

west dune Sep 15, 2023, 11:48 PM

It'll still be a bit, but you can send it over and they'll test it as soon as packaging and libraries are setup properly.

Hey I was reading this article: https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/ProgrammingWithCPP/DownloadingSourceCode/UpdatingSourceCode/

Updating to the Latest Changes from Epic

Describes how to update your fork of the Unreal Engine source code to get the latest fixes and new features.

#

and I noticed at the bottom there was an updating process for perforce

#

But it required this: After getting Perforce access from our support team

#

Would this be one of those things where you need to have one of those expensive unreal licences to access?

#

Sorry if this is the wrong place, but it does directly relate to the source code

#

You can copy this work flow by getting the new version from git and then integrating it into your perforce server using the same workflow they describe, but before I resort to that I thought I'd ask

I'm not sure you need to make your project a c++ enabled one, but you do need a source build of the engine to package a dedi server.

hey, a while ago I tried extending unreal's renderer to try to implement sea of thieve's cloud rendering tech myself
I found out about SceneViewExtensions, RDG and RHI and tried to figure them out from source code to no avail, just too complex for me
I come from Unity where drawing a mesh to a render target with a specific shader/material is just 2-3 function calls minimum
I've been told in order to understand unreal's rendering APIs I should learn other rendering APIs ie openGL or DirectX
For someone who doesn't have a comp sci degree but has some experience with unity's high level rendering api and with cpp, what is the ideal learning path here? what should I learn in what order?

As long as you didn't package any level editor code.

You'd have to create a "level editor" from scratch.

gusty pasture Hello everyone, let’s say I created a level editor in UE5, can I get the package...

For reference, I can say that the closest thing I know of is the "Building Unreal Engine as a Library" documentation page. I don't really think it's exactly what you're looking for though.
https://docs.unrealengine.com/5.3/en-US/building-unreal-engine-as-a-library/ Also, just be aware that the UE5 documentation page for this is not updated yet. Adding 4.27 for comparison: https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/BuildAsALibrary/

lethal ember Sep 21, 2023, 5:06 PM

#

Speaking of which, considering the documentation page above, I'm a bit confused by the "Engine Tools" EULA warning that it has. I read the part of the EULA that deals with Engine Tools, but... well, I'm still confused by it.

#

Suppose I made a project that followed the documentation above, and I was creating a project with Unreal Engine built as a library that the application could run. The project would be 100% non-commercial, and it would be a game. The reason I want to package it as a library is to use some external editor tools that will run before the game can be played properly. That said, could I allow end-users (players) to download and run this, according to the EULA?

blissful bramble Any tips on using Incredibuild? (BuildConfiguration settings, AWS Agent setups, ...

IncrediBuild is with a free license limited to a single normal core count of modern processors, it won't accelerate anything, so it will not help you but actually make it slower for you if you have more than 16 cores. If you want better, you need to pay them about $70-$90 per core license. That's going to be about $2500 a year if you use two 16-core machines. It's better to just buy a workstation for the amount of money you will hand them out in a few years and forever have a machine with you.

iron dome Sep 22, 2023, 5:12 PM

#

The free version of increditshit only lets you use a single process, not all the cores on 1 machine.

It's just ridiculous that it even limits you doing builds your one computer could do by itself.

Well, the main difference is core count. I have 32, so 64 concurrent processes. You can get 64 (128) or even 128 cores (256 processes,) if you're super rich and get the Epyc.

#

Consumer cpus, like Laura mentions, are a lot cheaper and have something like 16 cores/32 threads max?

Would anyone be able to help me understand what FPersonaAssetEditorToolkit is used for?

I see that it's being used in the animation editor modules and my initial assumption is that it's used to facilitate the different MODES.

But then I noticed it was not being utilized in other modules that also contain a mode inheriting from FApplicationMode - like the "BehaviorTreeEditorMode" or the "MaterialEditorMode".

It seems that it's mostly called in modules that interact with an skeletal rig. Is there a reason for that?

Edit: I now see that both the IBehaviorTreeEditor and the FPersonaAssetEditorToolkit inherit from FWorkFlowCentricApplication - they are more connected than I first thought.

Is there a good reference doc (other than Creating a Custom Asset Type with its own Editor in C++ community post) that can shed some light on the nuances of the AssetEditorToolkit?

Currently I'm getting a bit lost looking through existing subsystems. I've been looking through the a GenericGraphEditor project that was recommended in this discord. Since I need to add a timeline + viewport to a custom AssetEditor I've also been looking into existing implementation in Unreal and it's been somewhat confusing.

One area I hope can be clarified is the difference between a TabSummoner, a TabSpawner and a TabManager.

iron dome Sep 25, 2023, 9:06 PM

#

That's a good question

cunning mirage Sep 25, 2023, 10:42 PM

#

From my understanding summoners are used when we need to customize aspects of the WorkFlowTabFactory. Most classes seem to override CreateTabBody(), while others override SpawnTab(), ToolTipWidgets(), etc.

The WorkflowTabFactory contains a ptr to an FAssetEditorToolkit and is required for it's constructor. Its also used when creating a viewport, like in FPreviewViewportSummoner::CreateTabBody() in the TabSpawner.cpp for example.

Registering Tab Spawners is the bit thats confusing.

Anything that inherits from IToolKit calls the void RegisterTabSpawnerS()
TabManger is part of the SlateAPI and has its own "FTabSpawnerEntry& RegisterTabSpawner()" - (no "s")
WorkflowTabFactory is part of the UnrealEd and has its own "FTabSpawnerEntry& RegisterTabSpawner()" - (no "s")
TabSpawners is part of Persona namespace and inherits from WorkflowTabFactory, but has its own "FTabSpawnerEntry& RegisterTabSpawner()" - (no "s") and doesnt override the RegisterTabSpawner function from WorkflowTabFactory?

When I see "Mode" should I expect there to be multiple modes within an AssetEditor, or does the "Mode" affix/signifier also apply to single mode applications? I am asking because I see the the FModeToolkit::RegisterTabSpawners() inside the BaseToolKit.cpp but only under the ModeToolkit class and not the BaseToolKit class

iron dome Sep 25, 2023, 11:47 PM

#

You'll probably find that IToolKit is an old version that was never replaced.

#

WorkflowTabFactory will be the newer thing.

#

And, yeah, there are 2 kinds of modes, I think. Application modes which reflect major layout changes and toolkit modes which reflect the tool(set) currently being used in the editor.

#

// FApplicationMode

class FApplicationMode : public TSharedFromThis<FApplicationMode>``` top quality documentation

If you are aiming to release on consoles 4.27 plus was made to keep the SDK and so on matched so you can release. I've released a project on it and this is the version they backport most fixes. Although by now this is old news and they've given up on UE4 for good, rarely fixing only some critical things. If you intend to release this / early next year, then maybe you can still work on it, but anything further than that and you're risking beeing on 'too old' to release. Unless, of course, you're up for manually merging and keeping newest console SDK's up to date.

If you only need PC, you can use any version really.

On the Launcher Version of 5.3 if i make some small Edits on the Code of the Editor, doo i need the full Source Code for build it? (from github)

stable hemlock Sep 28, 2023, 8:59 AM

#

Yes. Any change you make to engine requires you to recompile it in order to work

#

Otherwise you just changed the C++ file, but the build binaries are from the launcher and nothing will change afaik

royal river Sep 28, 2023, 9:03 AM

So just for unclamping in the Post Process Volume the Diffuse Boost , i would get the Whole Source Build thats hundreds of Gigabytes.. thats sad

i don't mean launcher versions, i mean source build and custom installed builds from that source build version

#

thanks 😄 yeah i'll play around with it a bit ^^

#

I expect that installed builds with different options like target platforms and debugging symbols should be compatible right? just like the ones from the launcher

AutomationTool is the one that has all these conflicts, and it also has them when building from VS

This is barbaric, they should at least support 4.27 until at least 3 years

Ryan hummer mean when he says

Hi, thanks for the suggested fix, but we are not accepting PRs against 4.27. Support for VS2022 against 4.27 will be up to individual developers to handle.

So you found a fix, but they don't want to fix it, but your fix still works? Is there like a dedicated place to find "what 4.27 needs to survive" in 2023?

If this is your first time building from source:
I would still proceed to sanity check each and every step of the setup.
Unreal is very strict on what the thirdparty build pipeline setup is for each version of the engine.

( this is a couple of years old, but similar )
https://www.reddit.com/r/unrealengine/comments/sxv1bh/cant_compile_ue4_from_source_noexcept_types/

If this is not your first time building from source, something else must be off. Is this a clean fork off github, no changes, one of the release branches?

As long as those are Rider or VS with ReSharper.

Yeah, but technically isn't Rider made for only Unreal projects and CLion is for raw C++ projects. And Unreal itself is not an Unreal project 🧐

#

Basically I'm asking whether Rider borks itself on source code projects.

iron dome Sep 30, 2023, 9:02 AM

No

Rider isn't made for unreal only projects.

You probably have the wrong project selected. There's a dropdown next to the 'Development Editor' selection that should be your game project.

gilded latch Oct 1, 2023, 9:45 PM

#

yeah that happens when you build the engine. If you don't see your project in the configs you need to go through the folders of your solution, to Games -> ProjectName and run that, afterwards it should show up. In VS you can also make that your startup project

stable hemlock Oct 1, 2023, 9:46 PM

#

Well, I'm launching the engine from the engine solution, not the game solution. Is that wrong?

gilded latch Oct 1, 2023, 9:47 PM

#

well that will always bring you to the project browser

#

where you can choose to open an existing or create a new project

#

so once you have a project you should switch to your game solution

stable hemlock Oct 1, 2023, 9:48 PM

#

Oh. So I'll have to juggle solutions if I'm going to iterate on shaders a lot on a test project.

gilded latch Oct 1, 2023, 9:49 PM

#

i mean you can tick the box to always open the most recent project when launching the engine if you'll have to keep rebuilding the engine

#

(not sure how to undo that though)

stable hemlock Oct 1, 2023, 9:50 PM

#

Hmm, so that might work even if the browser never remembers last project?

#

I'll try that, thanks.

gilded latch Oct 1, 2023, 9:54 PM

#

is it okay to not include the DDC when creating an installed build? like will that be generated on each machine anyway, or am I taking away from the functionality or speed of the engine if i don't include it?
I need to share the engine build but i'd like to keep the download size small. 7zip gets it from 120-ish to under 20gb in ~45 minutes but i'd love to reduce it a bit further if possible

#

does it even make a difference in size?

gilded latch Oct 1, 2023, 10:22 PM

thanks!

does that take long?

removing the crash stack for the others should be okay though

you can use different configs together, right? just like in the launcher versions

The obvious ones:

Disable literally every single plugin you are not using
Mess with the packaging settings to use compression
Asset optimization: Smaller textures, delete unused assets, the usual stuff

The more complex:

Use a source build, and modify the engine to not package shit like the entirety of Chromium with unreal, lmao. That saves 200 mbs.

#

To help with point (1): You can add this line to your UProject, which will tell unreal to disable ALL plugins, except the ones you manually enable, which personally I do for every project.

#

its much faster to enable the 20 you need, rather than disabling the 50 you dont

C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\Microsoft.MakeFile.Targets(44,5): error MSB3073: The command "....\Build\BatchFiles\Build.bat -Target="UnrealEditor Win64 Development" -Target="ShaderCompileWorker Win64 Development -Quiet" -WaitMutex -FromMsBuild" exited with code -1073741571.

tranquil swift Hi! I really need to reduce my Source build's size. I'm already using somethi...

To add onto Drak's points:

Strip the PDBs. They contain a lot of data you don't need for debugging. If you are on windows, you can strip them using the built in tool called PDBSTRIP which you can find at C:\Program Files (x86)\Windows Kits\10\Debuggers\x64\srcsrv\pdbstr.exe. I find that the resulting PDB size is reduced by a magnitude of 100, making them usually as small as the binaries themselves.
If you have engine content that you don't intend on modifying, you can pack the source content directly into a pak file which reduces the content size by about 10-20% or more if you mess with compression such as LZ4. I've had my content size halved with LZ4 before. Then for the engine to detect the pak'd, you can use the -UsePaks flag when opening the editor - or find where it is used in the engine code and make the 1-line patch required to change the default behaviour to always load the pak file. You can continue to use the content exactly how you normally would, but again you just cannot save it.
Reducing texture quality can be done in bulk using an editor asset utility, or the bulk editor matrix asset action, or using a marketplace plugin called rdTextTools. You basically need to increase the LOD bias.
If you aren't using static/skeletal meshes, you can strip LOD levels from them, leaving just LOD0. You can do this in an editor utility script again, such as like this.

If you'd like more detail message me and I can link you to a writeup I've made relating to all this stuff, which I'd rather not link here in public as maybe it could be seen as shameless self promotion 🙂

Optimized builds can be difficult to debug because code can be moved or optimized out. Both of those things can cause the compiler to be unable to match up a breakpoint with a place that it can stop the application.
To really debug the engine you either have to a) build Debug Editor or b) use PRAGMA_DISABLE_OPTIMIZATION to deoptimize a specific file/function. Either one requires you to be building the engine from source and not an installed version.

I'm having trouble getting my unreal 5.3 source build to start in debugging mode. 5.3 source compiles and runs successfully and I can verify that the uproject is running on that version of Unreal. However, when I start the editor with Debug > Start New Instance, it tells me the UnrealEditor was built with a different version and asks if I'd like to recompile. Recompiling the engine doesn't remove this message. I can't start the debugger without this, anyone know what's going on?

Not sure what’s going on for you, but you can absolutely debug the engine source with Rider. I’ve done it before and I was doing it today.
There’s other cases where breakpoints won’t work, but it’ll take a bit to go over them. I gotta head to bed right now though.

Perhaps you could come up with some alternative angles of attack for the features you desire

lethal ember Oct 4, 2023, 4:16 PM

#

Essentially, I am looking to be able to build a game with assets cooked into pak files. Then removing certain assets from the cooked build, thus distributing a game without certain assets like selective 3D models and such. Then the end-user would start the game, and it would take assets from a folder on their computer, and bundle and replace the missing assets in the pak files, filling in the blank spaces.
It would be a long first-time load for any end-user, but after that it would be re-usable any load after that. I'm trying to avoid loading assets at run-time otherwise. Hoping I could include a sort of automatic asset building system into a game where it would load certain things at first run, so that those assets could be re-used later, instead of relying on loading assets at runtime.

#

I suppose the simplest alternative I can think of would be trying to invent my own type of pak file... but it would have to go deeper than that. I would have to create my own version of UAsset files too... At that point, might as well try to reverse engineer the real thing, because I'd be studying how it works already anyways.

Well, the intent is not to do anything illegal, that's the whole point. We can be awkward or obtuse with how we do it, but avoiding any legal issues. That's why I'm looking for other options. If it's not possible legally, then another approach should be taken, that's all.

#

I appreciate your time and input though. It may be time to look at a different engine for this, despite UE being first choice.

@lethal ember
I think for your use case, you're probably best off building an app that includes the code to parse the old data formats and convert to Unreal runtime formats at runtime. Later on you can look at caching these results if it's too slow, but first step is getting it working, then second step is making it fast.

Can parse old mesh formats and create procedural meshes in Unreal, etc.

There's a node that allows you to write shaders manually in the material editor. It's called 'custom expression' or something

That might alone solve your issue, or that's the best starting point

Keep in mind that using it you have to take care of cross-platform support on your own - not all custom shaders will compile ok for xbox or playstation. The Epic's material nodes are free of the issue.

calm mason Gets me everytime I setup a new build machine. Follow this: https://blog.devgeni...

Oh glad to hear its not me haha
Well I'm compiling for 5.3.0 and it gave me a warning saying that I should be doing it on VS2022 so I installed that and all of the stuff with it, and I also installed the WIN10SDK from the link it gave and I'm about halfway through a build now, hopefully I shouldn't encounter it again and have to do the modify thing in settings?

calm mason Oct 10, 2023, 2:46 PM

You will need to install pdbcopy as described in the blog. It doesn't get installed by default.

Ah okay gotcha ty

We are starting to need to distribute our source fork of the engine to developers - we are starting off with Installed Builds. Epic docs state they do not use this path in-house : does it mean they all use the project 'normally' via having git + IDE compile the editor for all devs, or is there a third path?

What are you trying to build? Make an Installed Build?

heady jackal Oct 11, 2023, 6:13 AM

#

I think so? I just need 5.3.0 to save my clouds in my project becuase 5.3.1 broke them ;w;

#

Yeah I want a installed build i think

calm mason Oct 11, 2023, 6:14 AM

#

Launcher does not let you sync prebuilt 5.3.0 ?

#

ok, tbh, no-one really 'builds' the whole engine from source usually.
what commandline you are using?

heady jackal Oct 11, 2023, 6:15 AM

#

Uh I don't think so bro? I've been told once you've updated to 5.3.1 you cant go back within the launcher

#

What are you hoping to do in the end?
Stick to using your custom 5.3.0 build for continuing development?

#

do you have team members you need to send this to too?

heady jackal Oct 11, 2023, 6:18 AM

#

No, my cloud scene with my SVTs turned into THIS when I upgraded to 5.3.1
https://cdn.discordapp.com/attachments/375020523240816640/1160907685567397888/image.png?ex=65365e88&is=6523e988&hm=582cc0002372397b28b75fb5d910b81aa233c36a463e9a4f7bfefbb44e63efcd&
And I just need to go back temporarily so I can work with them for a couple of weeks. This is for a commercial project that ends in a couple weeks so its a bit pressured 😅

heady jackal Oct 11, 2023, 6:18 AM

#

calm mason do you have team members you need to send this to too?

Prettymuch

calm mason Oct 11, 2023, 6:18 AM

#

oh man, sucks to be you! 😅

heady jackal Oct 11, 2023, 6:18 AM

#

Tell me about it!

#

So is there no simple way to backport to 5.3.0?

calm mason Oct 11, 2023, 6:19 AM

#

Well, making an Installed Build I guess is maybe the right approach for you, if you definitely cannot fix the cloud problem in 5.3.1

#

but it takes hella long as you've seen

heady jackal Oct 11, 2023, 6:20 AM

#

Yeah for sure its just difficult when I get random errors I don't understand and this documentation says nothing about exactly what I needhttps://docs.unrealengine.com/4.26/en-US/ProductionPipelines/DeployingTheEngine/UsinganInstalledBuild/

Using an Installed Build

This page describes the Installed Build process, including an overview of how to write Installed Build scripts.

calm mason Oct 11, 2023, 6:20 AM

#

Going back to your most recent error, looks like that Unreal Swarm project is using vs2019 to build, but maybe it's not setup for C# dev? or has the wrong components installed?

#

If it was just you, by far the easiest and quickest way is to setup your project with a source engine build, and it will only build the bits you actually need.

heady jackal Oct 11, 2023, 6:22 AM

#

How would one do that? Is that just essentially the same as installing a version from Epic Launcher ?

calm mason Oct 11, 2023, 6:23 AM

#

i.e.

root\    <-- 5.3.0 source in here
root\GenerateProjectFiles.bat
root\Engine\... etc

root\YourProject
root\YourProject\YourProject.uproject
root\YourProject\... etc

#

then you run GenerateProjectFiles.bat in the root and it gives you a sln with your project and engine combined.
set your project as the 'Startup Project' and build only it.

heady jackal Oct 11, 2023, 6:28 AM

#

Ah okay, lets hope that helps, I'll give that a go after I have my meeting with the other members of the team 😭😭😭 I really appreciate the help

astral elm Oct 11, 2023, 8:03 AM

#

heady jackal So is there no simple way to backport to 5.3.0?

Generally on "backporting" - if you have version control, nothing stops you from returning to a previous engine version. Generally speaking, you want to have 1 person dogfood the next-engine-version update and see how much stuff breaks, while others keep using the version you are on. Once the 1 person has things stable, optimally also packaging for your target platforms also, to catch more surprises. Then, and only then do we move to a new engine version in our operations.

calm mason Oct 11, 2023, 8:43 AM

#

I think the problem in this case is when using the Launcher version you can't get a specific minor version.

heady jackal Oct 11, 2023, 9:34 AM

Thanks for the help guys, but talked to my lead and we both think itd be better for me to try and bruteforce fix the problem and drop 5.3.0, despite the deadlines. At least I learned something about the engine if I ever need to do this again

heady jackal Oct 11, 2023, 8:45 PM

#

heady jackal Thanks for the help guys, but talked to my lead and we both think itd be better ...

Found out the issue was that on updating to 5.3.1, a bunch of my material nodes just decided to delete themselves. I'm kicking myself as I should have checked this first but the material compiled and gave no warning or errors that something was missing or broken or whatever, hence why I didn't check. Very annoying

If I made a really trivial PR, which really has no side effects, just a one liner at best (e.g. adding a meta specifier to auto cast the return type of an existing func), how long will it usually take for that to be accepted? or do I have to ping someone to ensure it doesn't go under the radar?

south vortex Oct 14, 2023, 6:36 AM

Your better off making the PR, but just rolling your own forked version of the source with that PR included. It’s easy to keep it in sync with all future UE releases.

Yeah I already do that, and I can easily cherry pick PRs from others too then I guess. But it's so weird to me that they don't have someone to take care of PRs. They constantly add new features while the bugs and PRs keep piling up.

Hi there.
Lets say I am a bit perflexed.. but UE4 doesn't support instancing with physics? All it does is static mesh instancing? World class game engine doesn't have this feature?
The closest I found is this: https://gist.github.com/jiangxiaoxu/c572d4064dce010a31cba3fc534ed1b3
I managed to get it compiled for 4.27 but maybe to my lesser skil in UE4 source code, I couldn't get it to work ie instances remains static. Any clue?

Anyone know a way to convert a "../Map/_Generated_/Map_MainGrid_L0_X0_Y0_DL0" runtime path to an actual .uasset path? I've been browsing the source but can't find a specific method 🙏

Update: Looking through my content folder I can't find any .umaps like you've got.

I can find the Map_WP.umap, but no Map_WP_MainGrid_XYZ.umap. I am using OFPA if that could affect this?

livid fiber Oct 19, 2023, 4:02 PM

Does anybody know if it is possible to build a dedicated server using installed build (the one from source, not launcher)

Thank you for the help 🙂 I'll have to check tomorrow, but I did realise I made a mistake. I'll do that cook and check Ty

timber sluice Oct 20, 2023, 7:36 AM

Content folder is ignore by default in the ignore file. Should we ignore it when uploading engine to source control?

iron dome Oct 20, 2023, 10:50 AM

If it's engine content, no?

timber sluice Oct 20, 2023, 10:54 AM

Hey, I just downloaded 5.3.1 from GitHub and it's missing the Redist folder. I assume a quick fix would be to copy from 5.2 but is there a way to report this to Epic?

#

Oh wait, I think I messed up when doing Setup.bat nevermind

lyric furnace Oct 22, 2023, 11:49 PM

#

I'm having a weird issue when running Setup.bat. For some reason, GitDependencies.exe seems to keep going into 'hibernation', or going into low power mode or something. When it's running, it generally sits at 0.0 MiB/s unless I spam the enter key in cmd and then it speeds up for a bit. If I stop spamming the enter key though it slowly drops back down to 0.0 download speed.

#

Anyone run into that issue before? (It's only doing it on one machine on my network so I don't think it's network related)

lyric furnace Oct 23, 2023, 1:08 AM

#

Err I give up. I've been fighting with this for two weeks. Ridiculous.

iron dome Oct 23, 2023, 1:34 AM

#

What version of the engine are you downloading for?

#

They changed the git stuff a little while ago and broke all teh old versions. Or something.

lyric furnace Oct 23, 2023, 1:54 AM

#

5.3

#

After 8 hours of the downloading during Setup.bat now it's hanging on generating the project files

#

Absolutely no errors, just sitting there processing taking up very little resources

#

Been going for 45 minutes so far

iron dome Oct 23, 2023, 1:56 AM

#

It sounds more like your computer is fubar somehow if that's the case.

lyric furnace Oct 23, 2023, 1:56 AM

#

I can't see how this is literally the only thing causing an issue

iron dome Oct 23, 2023, 1:56 AM

#

Generating project files doesn't do anything except access the files on your hd.

lyric furnace Oct 23, 2023, 1:56 AM

#

And I just came off a fresh windows install 12 hours ago

#

I don't think the generate files is the issue I think the constant start and stop of the Setup.bat over 8 hours is the issue and it broke the files

iron dome Oct 23, 2023, 1:57 AM

#

Doubt it.

south vortex Oct 23, 2023, 1:58 AM

#

I once had trouble doing a UE source install. Turns out I had faulty memory.

iron dome Oct 23, 2023, 1:58 AM

#

It doesn't even do anything related to your project files.

south vortex Oct 23, 2023, 1:58 AM

#

Do a memtest

lyric furnace Oct 23, 2023, 1:59 AM

#

The project files are generated based off the dependencies you tell it to install during Setup.bat no ?

iron dome Oct 23, 2023, 2:00 AM

#

No

#

The dependencies you download with setup.bat git are more like libraries adn stuff.

#

3rd party stuff.

#

The project files are 100% due to stuff downloaded from git.

#

Like the actual git source files, not the setup.bat stuff

lyric furnace Oct 23, 2023, 2:02 AM

#

I'm not downloading from git, I'm using a zip archive of the 5.3.1 release

iron dome Oct 23, 2023, 2:02 AM

#

Either way, the files in that zip are the only ones required to generate project files.

lyric furnace Oct 23, 2023, 2:03 AM

#

I don't think that's right. Running the generate project files before setup.bat throws an error

#

Well, if you haven't ran setup.bat before that is

iron dome Oct 23, 2023, 2:04 AM

#

Eh. Maybe.

#

I can't even remember what setup.bat downloads.

lyric furnace Oct 23, 2023, 2:04 AM

#

I can confirm it does, I tried that when I first started having the issue.

#

It runs gitdependencies against a .XML file of required dependencies

#

Out of all the things I use this machine for this is the only thing that is causing an issue. It worked without issue about a month ago when I compiled 5.1 from source. Now that won't even compile. Aside from UE though anything else I throw at it works without issue.

iron dome Oct 23, 2023, 2:07 AM

#

Still pretty sure none of those are related to your project. They just download some prereqs and setup the version selector.

#

You can do the latter bit manually.

#

Either way, is it sitll generating project files?

lyric furnace Oct 23, 2023, 2:08 AM

#

Yep

iron dome Oct 23, 2023, 2:08 AM

#

Leave it overnight? Or something.

lyric furnace Oct 23, 2023, 2:08 AM

#

No errors and it's sitting at 3% cpu usage and 15% memory usage

lyric furnace Oct 23, 2023, 4:27 PM

#

Well I am not sure what happened, but things are going much smoother today. I started the process again this morning from the start (like the 50th time doing this), and so far things are going good.

#

This PC compiles about 20x faster than the other machine, so if something goes wrong during build it's not as aggravating because I can get back there fairly quickly.

lyric furnace Oct 23, 2023, 10:30 PM

#

Well except I just noticed the PS5 package didn't compile but didn't present any errors

lyric furnace Oct 24, 2023, 12:59 AM

#

Hmm weird. it seems to be doing some weird stuff. It's trying to build platforms I told it to exclude, and it's not including platforms I told it to include. For example I excluded Linux, LinuxArm64, Android and IOS, and told it to include PS5 (I have access to the SDK), and IOS, Android and Linux are all available in the final build and PS5 isn't, even though the build log shows it was compiling it.

Just copying them over from the Engine/Marketplace folder says it's for a different version (even though the installed version and compiled version are both 5.3.1). Is it really needed to recompile the 'project' every time a new plugin is added to the system?

If you want the official git commit, you need to check for the 5.3.1 tag, not a branch or anything.

lyric furnace Oct 24, 2023, 7:37 PM

Okay so it seems like the process is: download 5.3 plugin from marketplace using an installed build. Copy from engine/marketplace to project/plugins/ regenerate project files, build game and commit changes to your version control for everyone else to get the updates

iron dome Oct 24, 2023, 8:15 PM
