UnrealVS quick build saves a lot of time instead of activating build via commandline

that goes beyond virtual remote workspace

😦

[weary tangle]

Seriously EPIC still hasn't fixed this forced iOS garbage thing❓ that i had to hack to finish building 5.0 in spring... well guess 5.1 for me goes on hacking InstalledEngineBuild.xml again 😵‍💫 .

Please Epic fix it once and for all so excluding iOS will avoid iOS stuff 100%, please🥺

[lean ridge]

hello, I liked my github and I still can't get access to the engine source

no, I looked for that

no reply email

on step 6

I can already verify (from 1st pic) that my github account is connected

and the last pic shows there was no email invitation

so sad 😦

[lean ridge]

@uncut herald Do you have any ideas? Like do you know someone at Epic Games I could email to help get this resolved?

Or an email address that would be able to handle this sort of thing

[thick furnace]

if no email received in over 24h try to redo steps

unlink and repeat from start

https://github.com/EpicGames/UnrealEngine/commit/1c9979bcfcd1ae37c6f122fdc56b15ef631b1e12

[coarse canyon]

Hot damn, is this really happening? 😄

[thick storm]

Other things, Time Of Day Editor, Muscle Simulation, all gone.. for now

[coarse canyon]

muscle sim = Chaos Flesh?

[thick storm]

yes

[coarse canyon]

ah well, we'll get them again 🙂 seems like Epic deemed they were not ready for even the experimental tag just yet

thanks for the insight into Iris above @thick storm I would very much like to follow more information on that, as it progresses. Sounds like a much more flexible and powerful framework, and will replace the older replication graph.

[thick storm]

no problem

I was dead set to get it working over weekend

i got, and it's still bugged :D, im reporting my finding to UDN as I get them

either way its really customizable, you no longer need replication graph

[coarse canyon]

Music to my ears!

does it already have things like network relevancy, or still pretty barebones?

[thick storm]

it doesn't work like that

[coarse canyon]

So what would be the approach to optimize network updates based on things like distance?

[thick storm]

gimme sec, I launch rider to check class names (;

to start from

you implmenet class called ReplicationBridge

it's implement by default to retain replication abilities from old system, but you can make your own if you wish

there also more classes you can implement like DataStream (which defines how things are well.. replicated), and NetBlob which is description of what is replicated

DataBridges

have classes DeltaCompression, Filters, Prioritizers

for Distance Based Update you can use Filter

you implement ie. grid, to updated objects only for players in the same cell

or you implement sphere to slow updated based on distance from center, and shut down updates outside of sphere

[coarse canyon]

what maintains the connection between an object (actor/entity) and the replicated data? some client ID like it was in replication?

[thick storm]

afaik yes, there is ID

[coarse canyon]

sounds like a pretty good pipeline that should be easy to extend and customize

Also "Prioritizers" sounds interesting, makes me wonder if you can set caps

[thick storm]

yeap, looking at it, you can throw away default implementation entirely and roll your own, without touching engine

Prioritizers as name implies determine priority for object update

it does not mean like 0>1

[coarse canyon]

so its order priority ok

[thick storm]

but you can gain iomplement grid

and prioritize object updates closer to hot spots

(players)

and in reverse more objects in single cell, will have lower priority

[coarse canyon]

one of the biggest problems I had in past multiplayer UE4 games was non-deterministic order of replication and having no control over it.. It was a nightmare when coupled with Child Actor components (which IMO noone should ever use)

[thick storm]

well it's still not deterministic

but you can now implement packet oredering

[coarse canyon]

probably not out of the box, but if you can make your own prioritizer you can have control over the important pieces

[thick storm]

the unfortunate part it is still using pollinig by default

but it's another configurable piece per class

[coarse canyon]

I never had a need to make the whole world deterministic, more like "group this and this actor together and replicate them in this order"

[thick storm]

that should be dobale, but you would need custom DataStream with reliable packet ordering

[coarse canyon]

or just adopt an architecture that doesnt need a deterministic order 🙂 its usually dependencies that are the issue

[thick storm]

there other nice as well

like

default serializer for TSharedPtr<>

I mean if it is USTRUCT()

there is also default serializer for Structs, which supports delta serialization

[coarse canyon]

nice

[thick storm]

(but it's not used by most structs by default, you have to create your own serializer and reuse it)

also you can you "compose" serializerzer,

[coarse canyon]

for anyone to adopt this, they need to provide a painless migration path so they will probably simulate how the existing replication works first

[thick storm]

get ptr to serializer for type, and reuse it

it works like that bydefault

it's harder when you had lots of NetSerializer/NetDeltaSerializer implemented

you have to rewrite everything to new system

[coarse canyon]

ah ok, new uproperty meta tags to control serialization and network, or based on the existing ones?

[thick storm]

I mean you have to implement new NetSerialization

that's very base

from NetSerializer.h

implementing this, of course won't make it work 😄

there is still more boilerplate to implement

[coarse canyon]

They are still working on this too, I expect them to make it easier to use before making it production ready

a good framework is easy to use by default, but customizable when you need

[thick storm]

actually once you get grasp of it, it's quite easy to use

[coarse canyon]

thats great news

[thick storm]

most of people will be scared by the typedefs and reinterpret_Cast<>

constexpr and statics

the good part of it

[coarse canyon]

well those are just modern language features 🙂 people need to stay with the times

[thick storm]

is that pretty much is allocation free, once serializers are allocated the only allocs are from replicated data

actually implementing something like Detal REplication

is far easier than in old system

where you had to roll you own handling of previous data

it's now all handled for you, and DeltaSerialize is called untill it get ackd

so it's safe to use bit packing to indicate what changed

[short pike]

I modified Stats2.h and build my Engine. But now the whole Engine builds again >.> I thought only the binaries for my modified files needs to be rebuilt. Can someone enlighten me?

[dark spindle]

Headers leak everywhere and trigger rebuilding of any user file

[jovial meadow]

anyone know how i can go about fixing this ?

Setting up Unreal Engine 4 project files...
The system cannot find the path specified.
Binding IntelliSense data... 100%
Writing project files... 0%
UnrealBuildTool Exception: System.IO.FileNotFoundException: C:\Program Files\Microsoft Visual Studio\2022\Preview\Common7\Tools../../VC/bin/x86_amd64\cl.exe

idk where to find this cl.ex, also how can i figure out what is talking about "The system cannot find the path specified."

is there a way i can go about debugging the header tool?

i don't have this issue with ue5 or ue 4.26/4.27, currently trying to build 4.8.1-release

[jovial meadow]

4.8.1-release

[jovial meadow]

@stable hemlock just realized im stupid but also got jebaited - after you wrote that now i understand 4.8 is really old

i was thinkng it was something inbetween 4.27 and 5

im trying to track down some bug that was introduced somewhere between 4.27 and 5, but i'm having nightmare building the none tagged engine versions

yeah i see now my bad

@stable hemlock i can build 4.25/4.27 - i just mean there is an issue introduced somewhere after 4.27 but also before the big ue5 release commit

i guess i should probablyt check the ue5 preview/early access versions

the weirdest thign for me is the commit before the big ue5 release can load ue4 projects without needing to go through that conversion pipeline - and also doesnt recognize ue5 projects

so in terms of the release branch, not quite sure when ue4 ends and ue5 starts

[full jewel]

the tags are the same as the launcher versions

[upper grove]

i'm getting a client crash with this message displayed, tbh I have no idea why it's happening, the code that is crashing it doesn't really have to do with slate or UI elements really. anyone know what might cause this?

[lean ridge]

@uncut herald I removed my account form epic-games and github (or I mean dis-connected them) then I went back and re-connected them and now I have access to all 16 repos 🙂

[short pike]

Recompiling the whole engine for little changes..
Isn't there a better way around it? 😩
I'm trying to fix Stats2.h for the prospero-clang compiler (maybe it's a cpp20 thing?) which seems to be more strict with the syntax, since it gives errors like:
error: arithmetic between different enumeration types
which doesn't come up when I normally build the engine.

I would love to manually compile just Stats2.h/cpp with the prospero-clang compiler just to see if it compiles correctly before building the whole engine.

Anyone got ideas? I don't want to spend a week fixing such a minor compile error 😣

[dark spindle]

No, there is no better way, this is how C++ works. Get a fast 12 cores CPU with 64GB RAM, put everything on a NVME drive.

What you could do is copy both files to a game project and try to iterate there

In non-Unreal projects you can actually compile single cpps, but that gets messy anyway with large files

Unreal doesn't have that afaik

[short pike]

That's seems like a plan. Thanks for the Answer and suggestion Weirder 🙏

[iron dome]

You could disable unity builds in every module... but watch the engine implode because their include structure is a joke.

And most of their modules interlink, so recompiling one will inevitably involve a massive chain reaction.

Not much they can do about that one.

[dark spindle]

This isn't going to help one bit

You still won't be able to compile a single .cpp file from Visual, and iteration time on header changes will be way slower

[iron dome]

It would help with the module_2343.cpp recompiling, making small iterative changes. Though I think they've solved that one internally.

[dark spindle]

We're talking header, not cpp changes, here

And unity build is not slower anymore in iteration, as long as you've got source control correctly set up

[iron dome]

Like I said just a line before!

[fathom tusk]

I've been adding MorphTarget support to the SkeletalMeshMerge and I think I'm really close but it's not quite working ... has anyone else done this successfully?

[fathom tusk]

of course I fix it shortly after asking for help

[iron dome]

Heh

I'm always doing that. Post question, then 5s later realise I'm an idiot, delete the question and get things working.

[delicate galleon]

It's my first time building the source for a server/mp project - and I gotta admit, my dual boot SSD wasn't ready for this 😅

[thick storm]

only 213gb ?

[hidden hedge]

probably built the entire engine rather than side-by-side

[unborn falcon]

I have a whole bunch of " C3861 'GetTypeHash': identifier not found " errors when trying to build source from the 5.1 branch. Any ideas?

[iron dome]

Try pulling the latest update again. The guy responsible was fixing that error yesterday I think.

[unborn falcon]

Gotcha! I'm an idiot. I thought I was doing that, but I still had a second local repository setup in github desktop, so I was pulling to the wrong repository...

I think it's working now. It's compiled 200 modules so far without any errors.

[iron dome]

Neat!

[humble mirage]

Im getting this error that I've seen other people get. I have the correct .net's installed from my understanding and I've seen some people suggest targeting 5.0 but I'm not familiar with how to do that

Here's my .nets

thanks for any suggestions anyone can povide

using VS 2019, idk if thats a problem

[delicate galleon]

When I was compiling yesterday, it worked for me with these (on VS 2022 / UE5)

[humble mirage]

shoot I might need to up to 2022 then

Im a person who doesnt want to do that

[delicate galleon]

wait you're on 5.1, nevermind - I was doing the release branch

[humble mirage]

yah, saw someone else saying 2022 was required so I'll give that a go

[long edge]

btw, what is that software

[delicate galleon]

WizTree. It's kinda like WinDirStat if you know that - just faster.

I managed to get the engine size down, eventually, by simply activating NTFS compression on .pdb and .obj files

[long edge]

would this have impact on debugging load time

[digital leaf]

yes

[zinc anchor]

Hey there, I've almost finished upgrading to 5.1, followed a lot of the threads here to help me as much as possible so thanks for those! 😄

I am running into an issue now with everything to do with Interchange, now.

When I try to generate project files, I get this: https://pastebin.com/y2ZmHzcU

So my questions are:

1.) has anybody seen this?
2.) how do I get rider to include excluded things like this? I've tried just reloading and it remains excluded

[humble mirage]

btw building with the settings suggested above worked perfect for me

for 5.1

on VS 2022

[zinc anchor]

yeah I've got all of that set for myself.. the issue here is that I can't even get to generating project files

[humble mirage]

oh hi just read your problem, I've never run into that myself. usually when something like that is going wrong I just restart the process (might be bad practice idk)

[zinc anchor]

okay all good, it looks like my issue was with having a stale interchange directory still existing in Plugins/Experimental while they'd migrated it outside of Experimental 🤦

[calm elk]

Hello, I have tried to clone and build from Github source using 5.1 branch and ue5-main...and each time it appears I end up with 5.03. Not 5.1. What am I doing wrong?

[delicate galleon]

I believe the default branch is release, did you specify the 5.1 branch when cloning?

[calm elk]

Yes, I selected that in the dropdown

[delicate galleon]

I'm not entirely sure what GitHub downloads select

I did it via cmdline

git clone https://github.com/EpicGames/UnrealEngine.git --branch {name} --depth 1

[humble mirage]

you have to use
git checkout 5.1
in your cmd line

at least that worked for me

[calm elk]

ah ok, interesting. I guess I will do this 5 hour process again!

thanks for the suggestion

[humble mirage]

yah after you clone and generate the projectfiles you can cd into UnrealEngine and then use
ls -a to browse branches

or wait sorry git branch -a

and then if you're wanting to use 5.1 use
git checkout 5.1
when you're cd'd into UnrealEngine

[calm elk]

ok cool thanks. Its strange the web/Git client does not work the same way

[humble mirage]

this whole process is strange lmao, Im an artist not a developer

[calm elk]

haha agreed. I am a musician 🙂

[calm elk]

yah, looks like the git website is kinda deceiving. Basically it still downloads the default Release branch (not the one you selected from the dropdown). So I should just do it via command line https://www.howtogeek.com/devops/how-to-clone-or-download-a-specific-branch-from-github/

[lean ridge]

Hello, any of you tried to build UE from source, I've had compiler issues when doing it. I was wondering which of you had success and what VS version and UE version you used. Thanks 👍

[dark spindle]

If you use a release tag and the VS + Win10 SDK version outlined in release notes, it will work 100% of the time

On UE5 source branches it's less surefire and some versions won't build, so you'd just take another one

[feral bane]

If you mean ue5-main source build, then if you don't get an answer for the next few hours I can check the commit I'm on when I get home. It's from around mid-late August and it's pretty stable. And of course I'm on VS2022 but I'll check the additions I have selected just to be sure for you (sdk etc).

[obtuse quarry]

I have a custom build of the engine relative to the project directory. I know that I can reference that engine build via a relative path inside of .uproject. Though I fail to specify it correctly. Can anybody tell me how it needs to look?
../ProjectFolder/UnrealEngine

[obtuse quarry]

Got it working: "./UnrealEngine"

[lean ridge]

I tried 4.27.2-release with VS 2022

I don't know if Rider has full support for UE5 yet, if it does, I'll upgrade

[dark spindle]

Make sure to use the version suggested in release notes if you have compile issues, sometimes VS releases have compiler issues / regressions etc

Using the same version is pretty much guaranteed to work though

[cloud jasper]

source engine

[lean ridge]

I think version 4.xx need VS 2019

So I'll build UE5 and see if Rider now supports it, thanks for help

[dark spindle]

It does not, especially 4.27 works fine AFAIK - not to mention you can use VS2022 with a much older compiler

This is what Epic recommends though:
Visual Studio 2019 v16.5
Windows SDK 10.0.18362

Actually used to compile releases: Visual Studio 2017 v15.9.4 toolchain (14.16.27023) and Windows 10 SDK (10.0.18362.0)

[lean ridge]

Thanks, I'll check to make sure I have that SDK.
I think I was able to successfully compile 4.27.1 though.
I'll check when I get off work

I'll check that toolchain too, thx

[coarse canyon]

Rider has been supporting UE5 since the EAP release 🙂 At first it was a separate "Rider for Unreal" release, but now its part of the main release and is excellent.

[lean ridge]

Great, I was using "Rider for Unreal" (pre release) with UE5 and it had extremely slow intellisense so I went back to UE4.
I'll try UE5 this weekend and see the improvements 🙂

[thick furnace]

wdym by "ue5 support" code is code, there is nothing specific about it

[coarse canyon]

Rider IDE integrates more into the engine 🙂 can search in BPs etc

[thick furnace]

that is optional thing and the plugin is separate from IDE

[lean ridge]

At the start, Rider for UE5 was poorly optimized and had as slow intellisense as Visual Studio

[thick furnace]

there is no "rider for ue5", there was only "rider for ue"

when tried rider for ue it was ok just more memory hungry, plus i use primarily r#

[heady sparrow]

Rider was certainly better than vs2019 in the first few early access versions for me

in sheer speed of finding symbols that is

[lone scaffold]

🤔

[thick storm]

rumors, that creative 2. might finally arrive in december

[nova sleet]

I'm using it and it's working perfectly

Right now with ue5

[iron dome]

Anything is gonna have slow intellisense until it's done its first complete code scan.

Gotta give it a while when you load up ue5 for the first time, I suspect.

Hello, anyone tested 5.1 modeling tools. how much changes it has? any pic? thanks.

[normal vortex]

anyone else getting crash after setting shader model to 6?

[swift pumice]

Would it be a dumb idea to try and ship on the 5.1 branch? With the nanite, lumen and d3d12 bug fixes I find that things almost always run better, and exhibit far less bugs. Is there anything else besides accepting that some niche things might not work and things will change very often (plus the occasional bug but 5.0.3 is already heavily buggy so I see it as a net gain)?

[dark spindle]

If you were already planning to ship 5.0, 5.1 is probably not much worse stability wise, but I'd wait a bit right now

It branched off like a week ago

[swift pumice]

yeah, thank you for the advice. I think its been two weeks, but yeah still pretty fresh

[dark spindle]

fwiw I'm planning on shipping a mid-october 5.1 branch myself

But I'm still seeing editor bugs today

[swift pumice]

yeah, there's been a few bugs but better than 5.0 honestly

[full jewel]

i can say there's TDR issues with nanite right now

at least on a 6800XT

[thick storm]

TDR ?

[coarse canyon]

It's not like UE4 didnt have bugs too 🙂 we all need to work around them or even sometimes fix in-engine ourselves.

[dark spindle]

5.1 right now is not exactly UE4 levels of stable

[swift pumice]

Thats a good point, i just had it in my mind that it was the unspoken rule to never ship on a non RC version. I can see that its silly to think like that though

[thick storm]

never ?

Fortnite is already at 5.1

😄

[dark spindle]

Most non indie titles ship on non-releases

As soon as you have a dedicated engine dev you're gonna stack up some minor changes to the engine

[swift pumice]

I feel like thats a recipe to get stuck on an old version of unreal but i guess thats a pessimistic view

[dark spindle]

Not really because you can rebase changes

But some studios definitely do lock on a specific version

If you don't need anything, why bother?

[pallid path]

And if you are planning on targeting consoles you will have to keep up to date as they change their sdk's, epic also updates the latest 5.N and 4.27 to keep up, but anything lower than that they dont
and you cant ship on some of them using old sdk's so there's that too to consider.

[dark spindle]

Arguably that's also things you can kinda manage yourself if you have a big team but.... Yeah

[light pewter]

Ok turns out the fix for this is putting bEnableUndefinedIdentifierWarnings = false; in HoloLensTargetPlatform.Build.cs and then downloading win sdk 18362

I think it's problem specifically with the OculusVR branch

[full jewel]

GPU crashing

[coarse canyon]

Even on smaller teams (12 and 30-ish in my case) we had engine mods that we merged into newer versions ourselves. If you have a solid process for it, the merge can take anywhere from a few hours to a couple days for large engine releases.

[hidden hedge]

well that's why we have a clean engine depot on p4 and an engine upgrade is syncing that up and then performing a merge to the actual game's copy of the engine

the merge conflicts are your engine changes

trying to compile a regular 4.24 cpp project but am getting an error in the engine code:
UE_4.24\Engine\Source\Runtime\Engine\Classes\Engine\Texture2D.h(168): error C4723: potential divide by 0
What do I do?

[dark spindle]

You might have a more recent version of Visual Studio that was intended for this engine release

You can probably patch the code (replacing the offending divider by X == 0 ? 1 : X or something like it)

But I'd suggest using the appropriate VS release instead

[thick furnace]

https://cdn.discordapp.com/attachments/221799439008923648/1003743795516539000/unknown.png

[coral fern]

so 4.24 release notes says : Visual Studio - Visual Studio 2017 v15.9.4 toolchain (14.16.27023) and Windows 10 SDK (10.0.16299.0)

Minimum Supported versions

Visual Studio 2017 v15.6

but the machine has VS 2019 installed would installing the selected items make it work?

[coral fern]

I installed the components but cant figure out how to change the project to use the older toolchain, it still says Using 14.29 instead of 14.16

[coral fern]

Using the BuildConfiguration.xml now

[coral fern]

Doesnt find 14.22.xxxx even though it was specified in the xml at the appdata roaming location, keeps defaulting to latest 14.29.XXXX

Have given up and am installing VS2017 since that is what works on my machine

Anyone have experience creating text files and writing to them on PS5 seems the same logic that works on PC doesn't work on PS5?

after i'm done with a rocket build, it looks like the bridge plugin is not included. how do i add that plugin to ue5?

[twilit minnow]

hi everyone, newbie here with github. i would like to build 5.1, wich i can do following the provided steps, but it seems to build for all platforms and the entire project folder becomes 205GB. i only need the windows build (working in virtual production). is there somewhere a guide how to do that? couldn't find much on google or ue forums, also don't really know what search terms to use.

[nova sleet]

Around 200gb is for a single platform/configuration

[timid scarab]

So I found that UE resets all non-editable properties in Blueprint components every time a property is edited. I don't like this behavior because it breaks my workflow but I also respect Epic's intentions here, despite not understanding them. Can anyone give me any examples on why this might be desired?

In my case, I am planning to preserve property values declared in C++ on instanced objects, which are not accessible to modify by Blueprints.

I think the fear was on construction scripts, you could basically have logic pile onto existing values

[twilit minnow]

copy, thx!

[weary tangle]

In spring when i builded 5.0 then after every build i copied bridge manually to rocket build plugins folder. Worked.

[misty edge]

friends, I downloaded the source and compiled it. When I right click on the upproject, the switch does not show the unreal engine version, what could be the reasons?

[full jewel]

i'm pretty sure running unreal version selector in the binaries folder will register it there

[iron dome]

It does.

If it isn't there, the setup.bat file will probably sort that out for you.

Has anybody had issues pulling or doing a fetch recently?

I installed github desktop on a new machine I built the other day and now I am getting fetch errors after it finishes downloading all the files

I have deleted the folder, put it in a new place, downloaded it 50 separate times

It works on my other PC, so I copied all the files, put them over to the other PC that is having issues and then did a "Clone from Location". I did not have a fetch option

did a verification and got a ton of errors, Tried to clear them but it just errors out with some silly errors saying it cant pull. I looked online and found that they might be related to "shallow" pull, but when I did the git command for a full pull it said it was full

even though it showed almost 20k files that were not resolved

i did not see any option on github desktop app to change from shallow to full\

when I attempt to download the repo via the ZIP, it just gives me a 400mb file and doesnt extract. I am at wits end, been doing this for a day now

[iron dome]

I'm not sure GHD has all those features. It's pretty simplistic.

[glacial hedge]

yeah, well it just worked the other day. However, I had a small issue with the PC (its new) and needed to install windows again

after doing such, no joy

it works flawlessly on my other PC, just this one seems off somehow

Don't get me wrong, I love GHD. 🙂

What are the error messages you actually get?

[glacial hedge]

one second

its int he middle of another download attempt

might be more than one second 😛

[iron dome]

I guess it's not because you haven't set your github login credentials.

What I immediately thought when you said you had to reinstall windows 😛

[glacial hedge]

"error: packfile .git/objects/pack/pack-37c1ffc0e5a11b4e80177aa5ea683763de50d5b9.pack does not match index
error: packfile .git/objects/pack/pack-37c1ffc0e5a11b4e80177aa5ea683763de50d5b9.pack does not match index"

i get a ton of those

i actually just did that, I removed my github from Unreal, then reconnected it, thinking the same thing

"error: delta replay has gone wild
fatal: pack has bad object at offset 13035161313: failed to apply delta
fatal: fetch-pack: invalid index-pack output
"

it errors out at about "Resolving deltas: 32% (1026134/3181046)"

[iron dome]

Are you sure your hd isn't just broken? 😛

[glacial hedge]

its brand new lol

[iron dome]

I've got no idea.

[glacial hedge]

yeah

[iron dome]

Brand new doesn't mean it works. 🙂

[glacial hedge]

i mean, im logged in 😛

and windows is functioning

[iron dome]

Have you tried checking it out via command line rather than ghd?

[glacial hedge]

well, im new to that, but I can try

that will be my next attempt if this shitshow doesnt work 😛

[iron dome]

GitHub gives you the commands to do that when you view a repo.

[glacial hedge]

its been a long time since I used gitbash

[iron dome]

just uses a dos prompt with the git executable.

[glacial hedge]

yeah

i got git installed already, after this last attempt I will give that one a go

[iron dome]

Don't use the same directory.

Check it out elsewhere.

[glacial hedge]

I created a new one

for this download

ill do the same again for the next one 😛

[iron dome]

Good luck! I'm off to bed. Sun will be up soon...

[glacial hedge]

Thanks for the suggestions

rest well

[glacial hedge]

this is the error

I uninstalled and then re-installed

makes no sense at all

[thick furnace]

use shallow clone if you have troubles pulling engine repo

make sure you have at least 300gb free

[glacial hedge]

I have well over 300gb free

and there is no option (that I can see) for shallow clone in Github Desktop

perhaps with GIT, I am using GITBASH right now to see if this changes things

will report when I am done

[thick furnace]

just dont use githubdesktop, it is quite bad

[glacial hedge]

😛

[thick furnace]

use regular git for windows

with any gui wrapper

[glacial hedge]

I am an artist, so it works for me (on my other desktop), but yes I am aware of git and know how to use it, just avoid it often

im going to set it up with jenkins anyway, so it doesnt really matter too much. If it works with gitbash then I am GTG

just so odd that it stopped working with the GitHub Desktop on that machine. No clue why

appreciate the thoughts, praying this works

its at 70% right now, so we will see

[thick furnace]

it seem just to be download error

which is common as needed to dl tons of files

[glacial hedge]

yeah, what is annoying is, you start over EVERY time 😛

[thick furnace]

thats why shallow clone is good - it pulls only N most recent commits and not whole git history of 500k commits

[glacial hedge]

😛

well, certainly agree. Just wish there was a way to set that in the github desktop, didnt see an option for it.

or an option to run a custom command line argument with the pull

might be in there, some place, we will see

[thick furnace]

doesnt it bundle with git for windows?

[glacial hedge]

yeah, I have a git GUI as well

i use to use that for my old C++ engine I was making with a friend. So, I am familiar with bash and the git UI

just prefer to use the clean looking and simple (fetch) from github desktop 😛 100% no difference

is what I am doing now

[thick furnace]

yeah, thats a full regular clone. you can add --depth=NumberofCommits like 1000 to pull only recent commits

[glacial hedge]

ah, perfect, thank you

[thick furnace]

oh, also --no-single-branch

so it pulls all branches initially if you dont specify exact branch to clone

[glacial hedge]

interesting

im only inserted in release branch

should that matter?

[thick furnace]

release is the default branch so should be ok

Create a shallow clone with a history truncated to the specified number of commits. Implies --single-branch unless --no-single-branch is given to fetch the histories near the tips of all branches. If you want to clone submodules shallowly, also pass --shallow-submodules.

[glacial hedge]

Coolio, excited to get this shizly automated with jenkins

then I can dev, press a button and then have it auto rebuild the server/client

been fiddling with this silly repo situation for an entire day now 😦

[thick furnace]

engine is just a bit too big to download quickly

[glacial hedge]

lol trust me, I know

this is the 10th time I have downloaded it

[thick furnace]

i had to make a script to download it by 10k commit batches

since office internet is bad (2mbps)

[glacial hedge]

yeah, I get that

im in Japan, so shit is super slow here for the US servers

and I was playing BF2042 while it was downloading 😛

[glacial hedge]

Same issue with git

... wtf

[glacial hedge]

@thick furnace so depth of 1000 seems to have worked, what do I need to do to get the rest of the files? or is there no need?

hm.. nevermind, it failed the checkout, it finished the download but failed checkout

ource/UnrealEngine/.git/objects/pack/pack-3b558e4a4eaa471e9068d57aa760a6db2d3167a8.pack) is corrupt
warning: Clone succeeded, but checkout failed.
You can inspect what was checked out with 'git status'
and retry with 'git restore --source=HEAD :/'

[thick furnace]

git fetch --unshallow

google for shallow clone for details

[glacial hedge]

daren@trabior MINGW64 /c/UE5Source
$ git fetch --unshallow
fatal: not a git repository (or any of the parent directories): .git

which is odd, goign to try one more thing

[thick furnace]

because you have subfolder /ue5source/unrealengine

[glacial hedge]

interesting...

i deleted that

C:\UnrealEngine is where it is at now

oh, I need to CD into that folder and THEN do it

feels stupid

okay, fetch is working now. I am on a good path now, Thank you so much for the help! ❤️

[timber sluice]

Hey, I need to built it from source for server purpose. That means everyone in the team has to do the same?

[iron dome]

If you use the same release tag from the source control, it should be okay, I think.

[thick furnace]

have a separate repository for source engine, and a way to share or sync binaries or have custom installed build

also UnrealVS has a handy "Build only startup project" that is a must-have

[misty edge]

I downloaded the source and compiled it. When I right click on the upproject, the switch does not show the unreal engine version, what could be the reasons?

I only find the version Selector from Launcher/Engine/Binaries/Win64…I have run it but it says “The current folder does not contain an engine installation”…

And I tried many other solutions.

[twilit needle]

During a full UE engine rebuild, all 16 cores pegged @ 100% usage, Visual Studio thought it might be helpful to suggest disabling ReSharper because of a 5 second UI responsiveness issue.

How TF does VS not understand that the compile I told it to do is what is killing the CPU? 🤣

Dumb tool.

[thick furnace]

in "Switch engine" you click on [...] button and select engine folder

or launch it at least once so it self-register in windows registry

[lone scaffold]

LWC seems to be one step closer

https://github.com/EpicGames/UnrealEngine/commit/63c5d8ae6df6cfea281ea8870433d17013cf0fdd

[thick storm]

only 88 mln km ?

unplayable

-;-

[full jewel]

wasn't the original estimate something really absurd?

[dark spindle]

The first estimates for LWC were Solar-system sized

Though anything above a couple of miles is big enough for most practical purposes

Either you're doing Flight Simulator, or you're gonna have a hard time modeling each grass blade on those 88km sized maps

[iron dome]

Wow, it doesn't even do sun to the earth?

I've always wondered, is that 93m miles from the centre of the Sun or the edge?

The edge being a very nebulous definition, in more ways than one.

[dark spindle]

Radius of the sun is a rounding error

But center

[iron dome]

Even the centre of the sun isn't exactly because it wobbles around as well due to the pull of gravity of the rest of the solar system.

[unkempt otter]

Has anyone by chance been experimenting with VR + lumen + nanite in 5.2 (ue5-main branch)? The performance pretty amazing, let alone the fact that it even works at all. However my packaged build has issues that don't happen in the editor - I'm seeing glitchiness in the left eye on any non-nanite assets (I can see those objects through walls and they shift around left/right as I turn my head), and the performance is a bit worse than the editor (maybe 5 or so less fps). I do realize this is literally the bleeding edge though lol so I'm not even really expecting an answer. In edtitor, getting 25-30 fps but in package it's like 20. scene is a fully detailed home interior with 30+ dynamic spotlights (toggled on/off depending on where you're standing to save perf)

[unkempt otter]

Ahhh.. the issue was Instanced Stereo turned on, issues are gone with that unchecked

[next edge]

anyone know how to get NVIDIA DLSS to compile for 5.1 ? I tried to use UnrealBuildTool.exe but get a bunch of errors

posting the errors might be helpful

actually maybe I fixed it-- seems like it was targeting VS 2019 but now that it's using VS 2022 it's making it much farther in the build

when I get ue5-main it fetches a bunch of files into the Engine\Plugins\Experimental\NNX\Source\ThirdParty\Deps\ folder. Can I stop this?
It adds them to my changelist, which gets really annoying when I'm trying to switch and merge branches.
If I remove them, they get added back next fetch.

have you tried SteamVR? Oculus is fine, but I get this crash with SteamVR:

Hmm, no I've just been using Oculus VR with the open XR plugin

Oh and when running the packaged exe I still get noticeably worse performance and consistent crashes :/

This is 5.2 though not 5.1

[quiet oracle]

You need to play in standalone with these launch parameters -vr -norhithread

@quiet oracle yea that was working for me for a moment but then it stopped working. I'm back to crashing no matter what with SteamVR

[sleek meadow]

How can I run standalone game with debug symbols attached ?

[dark spindle]

Add -game to VS debugging command line, press F5

Or run your packaged game and attach Visual, pass the pdbs when prompted

Or cook in editor, compile your packaged target and press F5

[coarse canyon]

Did you run setup.bat? those shell extensions should be there

[sleek meadow]

Do I need to cook assets and I need to compile in Development Editor configuration ?

[dark spindle]

In this mode, where you have the unpackaged uncooked game without editor, the defaults will work seamlessly

@thick storm I had a question about Iris, can you give me some clue? Is Iris based on actor like the old replication system? I'm wondering if Iris is a promising way to implement replication for Mass where an entity don't even have a actor binding to？

[thick storm]

Iris does not have any particular requriments

default implementation is for Actors/Objects

but you can just create your own

it's a lot of code to create custom DataStream/ReplicationBridge but it can be done without touching engine code

thanks alot

and unlike unreal script, Verse will probabaly have first party support from JetBrains

I just hope the final version of verse won't be anything like what we saw

unfortunetly.. I doubt it. It's conna be Python mixed with Lua and randomly throwed C

there were few references to it in code

I have a very old fork of UE on GitHub that is missing 50+ branches and 200+ tags compared to the EpicGames repo. GitHub has a 'sync fork' button but that only updates the currently selected branch.

does anyone have an issue, when sometimes Trace Store works (for Insigts, anim debugging etc), and sometimes dont ?

[iron dome]

Edit the uplugin and remove it?

Or changed "Enabled: true" to false.

[thick storm]

it doesn't change anything, since editor plain does not connect to trace store process

[lone scaffold]

Not sure about trace store but I used unreal insights a few times in UE5 and it worked fine. Iirc in UE4 it randomly stopped tracing on editor startup / did not catch up, so sometimes I had to restart the editor a few times (usually once or twice). Can't say for sure as it was long time ago.

[thick storm]

Yeah when it connects to trace store it works fine, but it does not always connect.. which is pretty annoying.

[jaunty seal]

anyone have luck using vs 2022 with ue5-main branch. The videos I have seen dont run into the below error.

build
start new instance then boom error

[jaunty seal]

Ya I am thinking so, going back to 5.0 non main 😄

[tired bolt]

Yeah I noticed, it's affecting all source control provider, but

 * @note This concept is currently only implemented for the Skein source control provider.

Any idea why they removed the SkeinSourceControl plugin from the Developer folder?

1. Is this to allow for undercover development and release it later as a surprise?
2. Or is it because they intend to release it through the Marketplace? Free or not, but it would allow for quicker iteration

[lone scaffold]

Very likely 1. They do it with most new functionality these days. When you look up recently added UE5 features like mass, these are just moved from Restricted folder. I suppose this was moved out of Restricted too soon because the actual Skein is not announced.

[thick storm]

There is special Restricted folder

and it's usually reserved for things, which either barerly work or not sure if ever release

[brave dirge]

curious if anyone has the 7950x

how it performs building source

[ornate rose]

Found a vid here:

https://www.youtube.com/watch?v=kzw4QQI__TU

It shows a simpler way of building ue5. I am wondering if you simply download ue5 main branch as a zip. This should work with
out any issues, right?

[heady sparrow]

the only difference is not having source control (cloning it is one button)

you definitely want source control

just cloning it is 90% the same as this video from what I can see

[ornate rose]

what is source control used for?

[heady sparrow]

git/perforce et al

anything to track changes so people can work together

and frankly even useful when working alone

what I'm saying is downloading the zip vs just clicking here is pretty much just as easy

[ornate rose]

Maybe I should get Git desktop.
I am trying to update my ue5 build. I used git clone -b ue5-main --single-branch https://github.com/EpicGames/UnrealEngine.git to build it in the past. How do I do a gitpull? I tried using git pull -b ue5-main --single-branch https://github.com/EpicGames/UnrealEngine.git

Didn't work.

[ornate rose]

But if you are working alone why would you need perforce especially if you are using a build that is not released yet which is why you are building from source.

[heady sparrow]

a single branch would be a much smaller download

github will just get the whole thing lol

[heady sparrow]

tracking and backing up your own changes in git

what happens when it crashes and you can't remember what you last did?

applies more to coding heavy projects but art can use them to

[ornate rose]

Ok. Thanks. You are saying that command is meant to download only the single branc which is a smaller download and cannot work with git pull as git pull will download the whole repository so in otherwords anytime you need to update, simply do a redownload of the ue5main build with git clone -b ue5-main --single-branch --depth=1 https://github.com/EpicGames/UnrealEngine.git and recompile?

[heady sparrow]

you need to clone it first to actually get it. pulling is when you pull their changes to change your local repo

you might need to fetch before pulling

honestly a git gui will make this a lot easier to understand

I still don't bother with learning every git command

github desktop is a bit too simple and will probably do a few extra branches you don't need but you may as well

[ornate rose]

How do I get Git gui?

[heady sparrow]

there are a few options

may as well go with this one

https://desktop.github.com/

I use git extensions but it's a fair bit harder to understand

and you can use both or whatever, they all just use your underlying git client

[ornate rose]

Thanks. But doesn't source control add to file size increase?

[heady sparrow]

yeah, the .git folder will get pretty large

you can do the single depth thing you were doing earlier which would heavily mitigate that

and there are ways to compress/clean up the git folder after

[ornate rose]

Ok. I have downloaded git desktop. Added the cloned branch I have to the app. It currently says no changes to the repository

Ok I see changes. I will try and look up tutorials of how to use the app to update my build. Thanks.

I am trying to pull, git desktop says bad access

I think I am having signing in issues with github desktop. Can't find authenticated user

Working now @heady sparrow I did a pull, it says unable to merge unrelated histories in this repository. I need to do a git fetch?

[heady sparrow]

may as well just do a hard reset on the latest commit when things get weird

[ornate rose]

How do I do that?

I need to use git reset --hard HEAD? I am not sure where to enter this in git desktop.

[heady sparrow]

man at this point you are better off googling a git tutorial

but yeah that command should work if the head is actually what you want

I just use git extensions to right click on the commit I want

[ornate rose]

No worries. Will just download the zip file and take it from there. I just wanted to test nanite with the pathtracer. Appreciate all the help. 🙂

How does one populate that file?

[ornate rose]

Do you think 5.1 will support pathtracing for Nanite? or will be in 5.2?

[tired bolt]

I don't know but I think it would be mentioned in the roadmap
https://portal.productboard.com/epicgames/1-unreal-engine-public-roadmap/c/846-path-tracing-improvements

[cursive spoke]

Does anyone know how to compile engine source on windows so that it has iOS support? (5.0.3)
https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/Mobile/iOS/Windows/
shows how to leverage a mac to build and package an iOS build from a windows editor, but their steps assume "iOS" shows up in the Edit -> Project Settings -> Platforms, but that is not true when GenerateProjectFiles.bat does not build for iOS.

iTunes was installed prior to running the setup scripts, but did not seem to help.

[cursive spoke]

Ok, I tracked it down. MobileDevice.dll was too new of a version

[ornate rose]

True. I think that would come for 5.2.

[tacit slate]

wait, there's a 5.1 branch now?

[dark spindle]

There's been for about a month I think

Maybe three weeks?

[tacit slate]

yeah, I didn't check in the last weeks (I was on vacation)

[nova sleet]

5.1 preview appeared on the launcher

[coarse canyon]

hmm nothing happens when I click Install on it?

[lyric tiger]

Same here.

[lone scaffold]

I have been always looking for the actual utilization of TObjectPtr lazy loading in the engine. Is this it?
https://github.com/EpicGames/UnrealEngine/commit/3476777206ad6a58a86065f87af8803f010546a6

[dark spindle]

Probably

[lone scaffold]

Yeah, seems BP is also updated internally to use them, so these types won't require full loading when referenced from BPs

https://github.com/EpicGames/UnrealEngine/commit/f90bd2583c4d8886543049303dea0123126081e7

[coarse canyon]

You think this is tied into the Virtual Assets feature?

[lone scaffold]

Hmm, not sure. I personally think not. I think this is about not loading all referenced objects when some asset is opened. Search for @TODO: OBJPTR actually revealed more of these. Basically faster asset opening in editor, lower RAM consumption and potentially also faster editor startups.
Virtual assets feel like a separate feature which just downloads the asset from server when used.
Maybe it could eventually lead to deferring virtual assets downloading until they are truly used, so there can be some link. But right now it seems LazyOnDemand meta is added to different classes than the ones using virtual assets.

[coarse canyon]

That alone is indeed a good change. I was investigating a slowdown opening an asset recently and checked what was happening behind the scenes.. whoa, almost all the project was being loaded at once.

And yeah I remember when they originally recommended using TObjectPtr, they said it was mainly for editor perf and future enhancements. It wont affect performance in a cooked build

[lone scaffold]

yes, it is a repeating problem for us too. All you need is a few BP casts going against common abstractions.

[thick storm]

i doubt that TObjectPtr will solve this problem

at best it will move it in different direction

you still need to everybody use FPrimaryAssetId or Soft references

[lone scaffold]

yeah, definitely not but there are todos for switching even UFunction to it. That could improve it for editing experience.

[thick storm]

I mean if opening assets in editor is slow, it's gonna be slow in game as well : D, so it's better not to hide that problem behind another smart pointer

because TObjectPtr<> is not going to work outside of editor build

[coarse canyon]

Cooked assets load faster and with less data the editor needs 🙂

[thick storm]

I know, but if it load half of project it is still not good ;d

[wintry coral]

Is there a Mac osx version of unreal? I am trying to pack a Mac game and I need to find unreal osx version but I can't

[coarse canyon]

Im not sure it does? Ive been assuming thats probably an editor only artifact? But I actually havent tested if its different in cooked build vs editor

[thick storm]

Afaik outside of editor TObjectPtr evaluates just to raw pointer

As the metadata is not accessible outside of editor

You still should make sure to use soft references

[kindred cobalt]

Anyone know of a primer for extending unreal's navigation/pathfinding system? I want to implement a flow field navigation method that utilizes & integrates with the existing navmesh functionality.

[lone scaffold]

editor loads additional referenced assets based on hard references and these are resolved same way in cooked game - by loading referenced assets. If your asset loads half of the project in the editor, I am 99% sure it does so also in the cooked version.

[lone scaffold]

Try #gameplay-ai but there is no good material I am aware of. You are probably on your own.

[kindred cobalt]

Yeah I figured ai would be more about behavior trees and not engine deep code. I'll give it a shot though, thanks.

[ornate rose]

5.1 preview has been released but will have to stick with the github branch as the pathtracer supports nanite. Hopefully we see it in 5.2 preview release.

[green briar]

More of a git related thing, but is there a decent way to set the default editor map per branch? I figure you'd need to untrack the ini file after being set to the right one for each branch (otherwise an eventual merge would undo the change anyway)? Any other ways that I'm missing?

[thick storm]

something interesting is happening i would say

im gonna check it but from description it's something similiar to marvelous

now im really waiting till they developed ML assisted tools

for skinning in editor 😄

[ornate rose]

Anyone sucessfully build from ue5 main in the last two days? Keep getting errors when I build in visual studio 2022

After you do a git pull, and run setup bat, and generate project files. bat, do you need to delete the ue5.sln file if you need to rerun setup.bat and GenerateProjectfiles.bat?

Thanks for the help. But I don't want ue5.1 preview. I am trying to get ue5main specifically. Will keep pulling till it works.

Is it better to Clean before rebuild in VS?

Ok. Thanks. If I am correct, after a pull, when you rerun setup and generateprojectfiles.bat, when you click on ue5.sln and open in VS, you click rebuild, right? Not build.

[thick storm]

just if anyone wonder, the pattern cloth editor is unusable

everytime i fix some crash there is another one, guess I will wait few days ;

[ornate rose]

Ok. So using build instead of rebuild will take less time to compile. Thanks.👍

[swift pumice]

How long does everyone's source builds usually take? Mine take 2-3 hours on a 10900k and I cant help but feel something is way off. I have a m.2 ssd and 64Gb of ram so there shouldnt be any bottleneck

[dark spindle]

Depends if it's a full build or a project build

[swift pumice]

Usually i just right click on the UE5 subproject and it throws 5000 files to compile

[dark spindle]

Assuming that's in your project's solution and not the full engine itself, i'd look at any plugin you're not using and disabling it

I usually get more in the 2500 range

[swift pumice]

Sorry, i wasnt clear. Its the engine source

Just went to do a project only build and this is what i get

[dark spindle]

Okay but the engine source should ideally be built from your project's Visual solution, rather than the UE5.sln file in the engine folder.

[swift pumice]

Oh really? Ive always just done it through the UE5 solution

[dark spindle]

There's your problem

[swift pumice]

Gotcha, thanks ill try that out

Still the same, 5000 files. Oh well :(

[dark spindle]

Make sure to disable unused plugins from your editor

Personally I have somewhat worse specs on my hardware and engine builds take about one hour usually

[swift pumice]

Gotcha, I cant head into the editor due to the engine not being built but do you have any recommendations for heavy plugins to disable so I can do it in my uproject?

[dark spindle]

Any you're not actively using

[swift pumice]

thanks ill be sure to do that

[thick storm]

ok I managed to patch the cloth plugin enough to at least start editor

and yeap it is simplified Marvelous

you can make cloth from patterns, simulate it and skin it

also there is experimental skeletal mesh editor

which while not really working also have options to edit skeletal meshes and skin them

I see Epic don't want you to ever leave the unreal editor 😄

[coarse canyon]

thats amazing! Thanks for the info @thick storm

[queen ridge]

Anyone using ue5-main and able to build and package a project? If so please let me know which commit you’re using, thanks.

[ornate rose]

Another error while building

[ornate rose]

Did another git pull, still compile errors. If anyone builds successfully, pls let us know if it works.

[lament oracle]

Failed to find shader type FSSDSpatialAccumulationCS in Platform SF_VULKAN_SM5

[steep sun]

Building DLSS plugin for 5.1 but getting build errors like ":\DLSS\DLSS510PreBuild\HostProject\Plugins\DLSS\Source\DLSS\Private\DLSSUpscaler.cpp(667): error C2923: 'TSharedPtr': 'ICustomStaticScreenPercentageData' is not a valid template type argument for parameter 'ObjectType'"

Why was CustomStaticScreenPercentage.h and CustomEditorStaticScreenPercentage.h deleted from 5.1 brnach?

Is DLSS NOT compatible with 5.1?

I'm trying to RUNAUAT.BAT on the DLSS plugin to rebuild it for 5.1. Was some fundamental change in DLSS expected?

[heady sparrow]

Looks like network prediction is alive? https://github.com/EpicGames/UnrealEngine/commits/ue5-main/Engine/Plugins/Runtime/NetworkPrediction

[dark spindle]

No, it's not

Like any code plugin it will be updated when 5.1 is available for good

[ornate rose]

Anyone able to build ue5 main recently?

[heady sparrow]

yeah, I had to make some world leak checks not fatal though 😓

I can get the commit ID if you like

[languid kayak]

f467590f16e904248e76b31e4eb6d06a055813e2

[ornate rose]

Thanks. My sincere apologies about the question I am about to ask. To do a git pull using the commit ID, you use'' git tag f467590f16e904248e76b31e4eb6d06a055813e2''?

after entering '' git pull origin ue5-main '' ?

[heady sparrow]

git merge f467590f16e904248e76b31e4eb6d06a055813e2 after you have it fetched

cherry picking might help... unsure

I generally just git extensions around

[ornate rose]

Ok. so use git fetch f467590f16e904248e76b31e4eb6d06a055813e2 first before merging. Thanks.

[dense phoenix]

@ornate rose I think you want to git checkout not git pull or git merge so:

git fetch ue5-main
git checkout ue5-main
git pull origin ue5-main
(make sure you are in root directory of repo)
git checkout f467590f1 .
(don't for get the dot)

I have never git merged a previous commit from the same branch to the same brach. Have no idea what it does.

[ornate rose]

Thanks a ton

@dense phoenix Sorry when you say in root directory of repo, you mean the git folder on your local hard drive?

[dense phoenix]

yeah

https://github.com/EpicGames/UnrealEngine

[heady sparrow]

oh yeah, I neglected the checkout step

[dense phoenix]

that is git project root

[heady sparrow]

my bad

[dense phoenix]

commit for reference https://github.com/EpicGames/UnrealEngine/commit/f467590f16e904248e76b31e4eb6d06a055813e2

[ornate rose]

@dense phoenix Thanks 👍

[ornate rose]

No worries man. Appreciate the commit ID you shared👍 Thanks again.

[heady sparrow]

Git Extensions makes me forgot what I'm doing with raw git commands

[ornate rose]

No worries. I am not familiar with building and git at all. Too much stress to wrap my head around tbh. Just want to make art. Hoping to try out pathtracer with nanite support. I am wondering if that feature will make it into 5.1's full release.

[ornate rose]

@dense phoenix I am not sure if I am doing this correctly🙏

Am I supposed to add the https://github.com/EpicGames/UnrealEngine after git checkout f467590f1?

I created my initial repository using git clone -b ue5-main --single-branch --depth=1 . So maybe thats why it saying it needs a worktree?

[glacial hedge]

I am working on getting Unreal Engine Source to pull via Jenkins, the issue is... it says the repo doesnt allow username and password pulls anymore. Does this mean I need to create a key on my GithubAccount and then try to link that via the Jenkins credentials system?

anybody has luck doing this?

I got the entire rest of the pipeline working. Would love to get a pull request from the repo + engine source build automated with a press of a jenkins job

[glacial hedge]

[ornate rose]

How do I that? with git config?

[ornate rose]

Thanks.

[ornate rose]

Its downloading now with git fetch origin commit ID and use git reset after. Thanks.👍

[dense phoenix]

Git checkout <git-hash> . (With no url) I was referencing the directory online with the url.

There is no such thing as a commit ID. Those are hashed representations in SHA1 format of the code at that commit.

The dot after the hash tells git to change all files in this directory and all sub directories.

Here are some guides that might help. https://devopscube.com/checkout-clone-specific-git-commit-id-sha/

https://stackoverflow.com/a/72741483

Git works in Unix systems, which is not windows.

Git bash for windows is a good way to do it.

git reset --hard $SHA1 deletes your work so I don’t use anything with —hard or -f unless someone has committed secrets or something

[dark spindle]

I mean, commit hashes are quite commonly referred to as IDs, even in the official doc. And Git works fine in any terminal on Windows, there's no need for Bash (Git also installs its own anyway)

[dense phoenix]

Oh, I have never heard of a git ID. But id’s are not hashes in my opinion. But yes most certainly they can be used to identify a commit. The dot part only works in *nix systems.

[dark spindle]

That's not true either

The git command line works the same everywhere, for the most part

[dense phoenix]

It works yes. I have messed up my work tree in windows git with dot before. The reason is trivial.

#engine-source message https://www.howtogeek.com/devops/how-to-set-up-https-personal-access-tokens-for-github-authentication/

You can use personal access token or ssh.

[dense phoenix]

Git bash is an emulator so not really windows. You probably know this. I was assuming that the person previously with the git problems was using git without git bash emulator.

Sorry I am on a train.

[dense phoenix]

https://www.howtogeek.com/devops/how-to-set-up-https-personal-access-tokens-for-github-authentication/

Sorry this has become a git channel. Maybe we need one.

[dark spindle]

There is one

[dark spindle]

For the record, all Git commands behave the same in the regular Windows terminal

There is no need for the Git Bash specifically, other than comfort

[glacial hedge]

@dense phoenix I did that, still getting errors

do I have to export my key and load it into Jenkins some place?

[coarse canyon]

sigh.. someone blocked the Git sync again with a huge PR with thousands of files..

[dense phoenix]

Are you using ssh or https? personal access token is for https

ssh errors are quite a hassle

[dense phoenix]

It has to do with windows vs nix filesystems. it's not important if you are strictly in windows. i agree windows commands work exactly the same. I just lost a lot of time with this difference once.

[glacial hedge]

@dense phoenix ill be honest, I have no clue what I am using 😛

i followed the steps the link you sent me

created that token

and this is the error that I get when I attempt to run it via jenkins

i set it for GITHUB project

and then under Source Code Management I get this

The goal, or intent, is when I run the build (or chronjob it) it will do a pull/fetch so that the local repo on my machine is up to date with the newest engine changes.

This way, I do a pull, complies the engine, gets latest from P4 (this works) builds my server, builds my client and then distributes it. Everything is working but the pull...

So, any help or guidance is certainly appreciated. I can do this manually of course (and I have been) just trying to get this working with Jenkins

Interesting note, when I go to the ssh clone option on the UnrealEngine page, this is what I see

the key you linked me to make, does not seem to "like" the ones that Epic is requesting

This is what it wants me to make

I was following this "string of thought" a bit ago. I created a local key on my build machine and then tried to load that in, but it seems that didnt work... so, any guide or ideas on how to get that to work might be the answer. Seems so silly.... but I get it for security reasons

[dense phoenix]

jenkins plugin uses ssh i think

[glacial hedge]

I think so as well, but trying to figure out where I am missing the link here. Seems like jenkins isnt pulling my github stuff to supply to Epics repo

[dense phoenix]

add credentials

and change the url to the https one

add personal access token to the credentials

[glacial hedge]

glad somebody else thinks like me 😛

did that already

[dense phoenix]

did you make a personal access token?

that should be in place of where you put a password

[glacial hedge]

https://cdn.discordapp.com/attachments/375021179075035147/1029052926825611264/unknown.png

[dense phoenix]

generate a new token and copy paste it into credentials

[glacial hedge]

you cant copy paste, you have to use this screen

and those are your choices

[dense phoenix]

generate a new personal token in github and copy it

then paste it in password

[glacial hedge]

ype, did that

k, one sec

... that might have worked.... you devil dog you

and this branch, should be release, right?

[dense phoenix]

for ue4 not ue5 I would think yes

I have only compiled ue5

[glacial hedge]

k, cause I put release in there, and this is the build error i get

I am doing UE5

its looking for origin for some odd reason

[dense phoenix]

so not ssh username and password

just username and password

ue5 branch is ue5-main

[glacial hedge]

yeah, i put that in there, but its still looking for origin.... need to do some digging

[dense phoenix]

your checkout branch

it's still trying to use ssh

status code 128 is ssh error

[glacial hedge]

hm...

interesting

[dense phoenix]

you can set up ssh if it really wants it

that is a different thing in github

https://github.com/settings/keys there are help documents there

[glacial hedge]

copy, going to look into that. thanks

[junior hare]

Hiya, does anyone know where the rendering for the transform tool is done? I'm sick of the bug where it inverts when you get too close when it's editing a parented actor and am going to fix it

Found it, UnrealWidgetRender.cpp for any future searchers. rendering is done in FWidget::Render_Rotate, FWidget::Render_Translate, etc

[ornate rose]

I did try that in line 11 of the image :#engine-source message

It says this operation must be run in a work tree

[dense phoenix]

i don't think i've ever gone into the .git folder

not sure if a work tree exists in .git directory

that's not the root though for sure

trying to recreate but it taking a good long while

#source-control looks like experts in all things like this though @ornate rose

[ornate rose]

Appreciate the help. Thanks.

git fetch origin commit ID seems to work. I think its because I did a git clone of ue5main only and not the whole repository?

[dense phoenix]

git pull = git fetch + git merge. Git fetch doesn’t change any of your files. It just gets the git metadata that contains the file changes. Git fetch —all will get all branches metadata from remote repo, but no code changes. If someone pushes a new branch to the remote repo on GitHub after you cloned it, you have to fetch it before checking it out. @ornate rose

Git fetch might include code in a new branch fetched. It just doesn’t change existing code on your local repo.

I don’t remember.

[ornate rose]

@dense phoenix I used git pull origin commit ID and I have downloaded it to my local repository. I then used git reset --hard FETCH_HEAD. Ran setup.bat and GenerateProjectFiles.bat. I am building now using VS currently. Fingers crossed. I don't know why git checkout doesn't work. I had an initial error whenever I opened the ue5.sln file. Turns out I had to delete the .suo file in the .vs folder. So it works now.

The hassles of building ue5 are worth writing a book about lol 😆 I get the ue5main is only meant for testing but it would be nice if they could just have a snapshot at intervals so that ppl who want to test can try it. Instead of ppl going to so much length to find the last commit ID that worked.

[ornate rose]

Still getting this error: #engine-source message

I keep getting this anytime I build.

Maybe I ahould delete the whole folder and restart again?

[dark spindle]

Show the actual compiler output, error list is always wrong.

[ornate rose]

Its still building atm over 4 hrs now.

[ornate rose]

If I check the errors tab. Thats shows up. Or should I ignore it?

[dark spindle]

Yes, the error tab is 100% bullshit and should never be looked at

The compiler log is the ground truth

(And if the engine build takes more than an hour, you probably want to move everything to an SSD or NVME drive, invest in RAM, compile only from your C++ project's solution, disable all plugins)

[ornate rose]

Ok thanks. Might be the ssd. I am using a 64gb ram laptop so I am not sure why. I will try to be patient.

@dark spindle Nope. Didn't work

I get this error when I try to run unrealeditor.exe

[dark spindle]

So what is the error in that window now?

[ornate rose]

Or am I supposed to update VS 2022 to the latest update?

[dark spindle]

That's the error window - close it and never look at it again in your entire life

Show the compiler error in the output log

[ornate rose]

Ok Thanks. I am curious what might be causing it. Since other people have been able to build theirs. I am not sure if its something I need or not. Its definitely an experiemental plugin: [5441/5889] Link UnrealEditor-NNXUtils.dll
8> Creating library ..\Plugins\Experimental\NNX\Intermediate\Build\Win64\UnrealEditor\Development\NNXUtils\UnrealEditor-NNXUtils.suppressed.lib and object ..\Plugins\Experimental\NNX\Intermediate\Build\Win64\UnrealEditor\Development\NNXUtils\UnrealEditor-NNXUtils.suppressed.exp

If I don't need it. I can delete it and do a rebuild?

[dark spindle]

Again, just disable the plugin and build from your project

[ornate rose]

Ok. Thanks

[ornate rose]

Dumb question: How do I disable the plugin in Visual studio?

The only option I have is to delete it. I need to build ue5 to be able to open ue5 to disable the plugin.

Sorry where is .uplugin located? in the git folder?

found this: https://forums.unrealengine.com/t/error-msb3073-building-4-26-caused-by-extra-quotation-mark/471123/5

Seems deleting the offending folder solved the issue. I will give it a go.

[dark spindle]

You don't

You disable it in your uproject file, or the engine's Plugins list

[ornate rose]

can you pls tell me where the engine's plugin list is usually located?

[dark spindle]

Edit / plugins

[ornate rose]

In the git folder?

[dark spindle]

In the Unreal Editor

[ornate rose]

I can't do that because I can't build Unreal to access the Editor

[dark spindle]

You'll have to either edit the uproject manually, or use another Unreal build

Make sure you regularly disable unused plugins when upgrading the engine

You'll have compile time and avoid such issues

[ornate rose]

Ok. Thanks.

Ah. Thank you. I deleted the NNX folder and I am rebuilding in VS studio. Just a test to see if the build would be successful based on the ue forums post.

[ornate rose]

Hmmm...this is how the NNX.uplugin looks like now in VS after deleting it and currently rebuilding.

It has a red x which means its probably disabled. Fingers crossed.

[thick storm]

add plugin to your uproject and set "Enabled" : false

[ornate rose]

Guys. It finally succeeded:

🙂

Turns out deleting the folder worked.

Thanks to everyone here who helped me. Won't be possible without your help 👍

[storm mesa]

Building the engine is going pretty slowly, but cpu and memory aren't being used very much. Is this expected?
E: seems like starting the build with a decent amount of memory being consumed did not allow the build to fully utilize available resources. Going full speed now

Hi, does anyone know if there's support for Unreal Engine as a Library in Unreal Engine 5? I'm trying to compile it as in docs, but there're still errors I can't resolve. It's all about IMPLEMENT_MODULE and IMPLEMENT_MODULE_USD

[strange swift]

support for Unreal Engine as a Library

wot?

[vital hawk]

New thing from 4.27
https://docs.unrealengine.com/4.27/en-US/SharingAndReleasing/BuildAsALibrary/

[strange swift]

Huh

[hidden hedge]

https://docs.unrealengine.com/5.0/en-US/building-unreal-engine-as-a-library/

this is the 5.0 specific page, and it specifically mentions your project's Target.cs

[arctic wing]

Yeah, I used that page, and thought that by project they meant unreal engine source project, screenshot of target.cs file from which I attached to my message. Is it target.cs file for some different project additionally to source code project?

[hidden hedge]

the "Target.cs for your project" is pretty clear cut

Hey guys I am trying to install UE5 source using this video https://www.youtube.com/watch?v=_7TQynJ_TrQ. but in the video when they do "git tag" it goes to 5.0 while when i do it i only get to 4.17, any reason why?

trying to build 5.1 from git.... but getting this after building on tryiong to debug: Unable to read module manifest from '../../../Engine/Binaries/Win64/UnrealEditor.modules'. Module manifests are generated at build time, and must be present to locate modules at runtime.
A breakpoint instruction (__debugbreak() statement or a similar call) was executed in UnrealEditor.exe.

not sure what thats all about, previous versions built and ran just fine

missing dependancy?

I do hope it comes to mainline sooner than later

[hidden hedge]

might be the first public outing for verse

[thick storm]

yeah, i guess they will add verse in 5.2

im really interested in tools that allow to modify game live from editor

that was beyond awesome

[lone scaffold]

sounds game specific / like something they would like to keep for FN only. But Verse is coming.

[thick storm]

still I guess it has something to do with commits "cooked editor"

and seems like something which can be a plugin

[stable hemlock]

there's no specific code for verse on the p4 ?

[lone scaffold]

Last time I checked P4 was more or less same stuff as git. I think they moved away from UE4 approach where licensees had access to a lot of WIP stuff. Also a lot of development is now happening in Main but in Restricted folders which are private.

[vale fractal]

How can I pull ULevel metrics, like number of blueprints referenced and file size? I wanna use this for an editor tool

[strange swift]

I believe in order to answer this, you'll have to find it within the engine code for yourself

It looks like Level.h/cpp - ULevel::AddReferencedObjects might be a good starting point.

[tepid marsh]

Adding a source effect preset to a source effect preset chain, and then referencing that chain in a Sound Cue will cause the source effect to not load correctly when restarting Unreal 5.0.3 due to "because its class (SourceEffectPreset) does not exist". Any ideas here? I am suspecting that there is a loading phase issue here but not sure what to alter in order to get it working.

[vale fractal]

I’ll take a look here, thank you!

[vale fractal]

I ended up deciding that’s what I needed to do. Yesterday I dug through AssetData, ContentBrower/ContentBrowserData, and EditorUtilityLibrary.

[summer pelican]

Have a look at the SizeMap tool, it shows referenced objects for a given asset and the estimated size of each of those assets. It works on levels as well:

Yes, I meant to have a look at how it was set up as it will have the relevant functions inside of it. While I don't know the exact functions needed that tool should be a good reference point

[vale fractal]

Thanks, I’ll dig around that

[plain wedge]

Hi, how can I change the project version from ue5_main branch to release?

[coarse canyon]

Depends on what version your main branch is. If you are already using a version higher than the release version, then you cant. If you are using main that is version 5.1, then you can move your project over to 5.1 when its released soon or use the preview release.

[coarse canyon]

5.1 preview 2 is out on launcher 🙂

[stark tiger]

Hi All, I want to dig into the engine source to figure out where the networking code is located to play with some experimental ideas on possible P2P integrations. Yea, I know that some have said that this is not a good approach, but I have some ideas that might be interested to test out. With one of them being for the nodes to serve many small files like I saw in a recent YouTube video on UE5 about how many developers can work on the same map levels and world at the same time by having each asset as an individual chunk. Could be something there for world serving, I think.

[amber junco]

hi

is there an easy way to say which version u have via source code files ? i cant launch the editor

there seems no info in readme or anywhere

ok got it. under engine/build/version or something

[summer pelican]

Engine\Source\Runtime\Launch\Resources\Version.h will show the engine version

I'm hoping for a Fortnite Creative 2.0 announcement along with Verse 😄

[thick storm]

im 99% sure it releases in december

[turbid sigil]

before I start on this long path, no one has ported VRWorks to any version past 4.18 right? I've searched for a bit and found nothing, but want to make sure no one has done this before I sink hours into it

[hidden hedge]

I still reserve a bit of skepticism over Epic rolling their own VCS. It'll be essentially be unproven (PlasticSCM flashbacks, and that one still has weird problems) and I'd hate the EULA to restrict its use exclusively with Unreal

[small isle]

Rightfully so. But I'm hopeful for something new to shake up the status quo. Git itself is great for code but Git+lfs is...... Okish for games. Haven't used plastic. Perforce has some annoyances but is my favourite of the bunch for this purpose.

But skepticism is definitely warranted.

It's a very high risk to use a new vcs, and it's very easy for a bug to corrupt everything

[hidden hedge]

Like Visual SourceSafe of old

[small isle]

I'm lucky enough to have avoided that. Started with svn around 03-04

[hidden hedge]

I'd be less skeptical if it was a true open source project that isn't tied to Unreal. Like storing web projects, and at my old job we had projects on other engines

Well same but I've heard the stories online

[small isle]

Yep. I love the origin story of git. I'd love something like that designed from the ground up for mixed use of code and binaries

[hidden hedge]

We'll see once there's more info than random references being scraped from commits

[lone scaffold]

This is a good thing. It is not Horde itself. It is Horde Storage which was already once renamed, I think from Jupiter. As far as I understand, Horde Storage does not have that many things in common with Horde. Horde Storage is a backend for uploading and downloading big binaries. I think it is developed mainly because of shared derived data cache in cloud. In UE4 this was usually done by having DDC on AWS as S3 storage.

[coarse canyon]

Yeah there is a talk at UnrealFest by the Coalition about using Horde Storage and its already called Unreal Cloud DDC there. Just made me wonder if they are using that branding for all of the tools.

[lone scaffold]

I was under the opinion that they want to use it as a more generic binaries storage, so the renaming to "DDC" surprised me a bit. I imagined it as something what could also store big artifacts for Horde like packaged games and possibly also shared intermediate files for devs for fast iterative cooks.

[coarse canyon]

Yeah good point.

Has anyone dug into the new Virtual Assets feature in 5.1 yet? I've been wondering if it requires Perforce or uses something like the Horde Storage feature

A lot of teams (mine included) are working fully remote, distributed across multiple countries. So any features that help with that (and not needing a central office server setup) are going to be great

[thick storm]

Virtual Assets were at some point tied to Jupiter

I think they still need Horde Storge aka Cloud Storage

I tried to test it, but got stuck at deploying horde, it's docker container.. but I cloudn't figure out all the configuration

[lone scaffold]

Nice info on Cloud DDC

https://github.com/EpicGames/UnrealEngine/tree/ue5-main/Engine/Source/Programs/UnrealCloudDDC

[thick storm]

so it Rquires ScyllaDB, that would explain why it is hard to deploy ;

Hi everyone, I have a question about Epic Games Launcher recognising source engine build. The thing is, I have built UE 4.27 and UE 5.0 from source and installed Epic Games Launcher after that in order to install a plugin. But EGL does not show any UE versions available. I was told that the only way to install the plugin is to install a stock 4.27 and/or 5.0, install the plugin to that stock version and then copy the plugin to the one built from source. Is this really the only way?..

[strange swift]

Unless you can find the raw plugin files somewhere then yeah just do that

[coarse canyon]

Why do you want your source builds in the launcher? I've not had to do that once. If its simply to install a plugin that will install to Engine only, then yes install to a vanilla engine version, then copy the plugin files into your game folder (IMO you should always do that anyway)

Only you install (say for 5.0), you can find your plugin files here:
C:\Program Files\Epic Games\UE_5.0\Engine\Plugins\Marketplace\

[urban lagoon]

Thanks!

[tired bolt]

It might be a question from someone used to how Unity Hub works (at least for Unity devs with source code access, I realize it's probably not the case)
In any case, it's a nice thing from the Unity Hub 🙂

[lone scaffold]

correction: cooked assets are using different system called Zen (Store). https://docs.unrealengine.com/5.0/en-US/zen-store-in-unreal-engine/

[coarse canyon]

It is indeed built for more things than just the DDC, they confirmed it in an UnrealFest talk today (the geo-distributed one with Coalition)

[lone scaffold]

Nice, thanks for info!

[hidden hedge]

a missed find and replace on that readme

[coarse canyon]

both AWS and Azure are supported. Epic uses AWS, but Coalition uses it on Azure.

Any one experiencing AMD related issues with 5.1? I've had multiple users report gpu crashes (6900XT, 6600XT and Vega cards)

they claim to have their drivers up to date or could this be caused by an outdated windows build?

[nova sleet]

Depends what they mean by latest drivers, optional drivers or "recommended"
Optional are the up to date ones and they should be used

[swift pumice]

ill ask, thank you very much

[weary locust]

Non-WHQL drivers always have issues for me. The September ones broke browser hardware acceleration, and Youtube among other things. :))))

[brave dirge]

how is preview 2?

[pulsar kestrel]

Has anyone here managed to make clangd work nicely with Unreal on Windows? I've made some changes to UBT's GenerateClangDatabase.cs which help (making sure it uses the clang-cl flags rather than the clang ones and adding the .generated.h folder paths), but it's still not quite there yet in terms of code navigation or reference finding. Any tips would be highly appreciated.

[swift pumice]

It was on a shipping build but I’ll try to send someone a test build to try, thank you!

[nova sleet]

Oh yeah HW acceleration on stuff like YT videos is broken on some GPUs with the optional drivers but it should be fixed with the next update

But in general I find them much more stable

I can't access the repo because I removed myself from the Epic Games organization on GitHub at one point. Now I don't see anywhere to rejoin so I can access the repo. What should I do?
