so... we're hooking up new branches to github, once that is done, the mirror will resume

Thanks for the update RCL, appreciate it 🙂

#

umm what happened to the branches?

#

What does it mean ? I am not that deep into git yet

torpid valve
#

main branch started to sync (;

#

Lets hope iOS will be patched out too so there would be no need for hacks anymore to build Unreal, for those who use --exclude=IOS with setup.bat and -set:HostPlatformOnly=true with RunUAT.

Waiting for 5.0 branch...

those duplicate commits in ue5-main doesn't seem nice

Let me try UE5 next then… UE4.27 didn’t require any copying of files; just a custom script.

#

feels like they kinda gave up giving us new main commits after somebody accidentally doubled the commits

#

c'mon... it was getting really interesting

oblique mist
#

Build started; Win64 only. Will take a little while... (especially on task 10). Currently on task [3/11]

First error, but it looks unrelated...

LogWindows: Error: ICU data directory was not discovered:
    LogWindows: Error: ../../../../../Templates/TP_AEC_ArchvisBP/Content/Internationalization
    LogWindows: Error: ../../../Engine/Content/Internationalization

The latter folder exists, so I wonder why it failed... 🤔

stark basin
#

something like RunUAT BuildGraph -script=Engine/Build/InstalledEngineBuild.xml -target="Make Installed Build Win64" -nosign -set:WithDDC=false -set:WithIOS=false -set:WithTVOS=false -set:WithMac=false -verbose

oblique mist
stark basin
#

oh really? is there a different node that depends on it? Let me see with -listonly

oblique mist
stark basin
#

So, just RunUAT BuildGraph -script=Engine/Build/InstalledEngineBuild.xml -target="Make Installed Build Win64" -listonly does not list any Mac/iOS nodes at all for me, which is consistent with this line in xml:

<Property Name="DefaultWithIOS" Value="false" If="'$(HostPlatform)' != 'Mac' And !$(AllPlatforms)"/>

(i.e. it seems to be off for non-Mac hosts by default)

#

it does list Linux ones, but if I add -set:WithLinux=false -set:WithLinuxAArch64=false they're gone

oblique mist
#

I have yet to explain why, but the build output says otherwise... 🤷‍♂️

stark basin
#

would you paste your commandline so I could try?

#

kill all the absolute paths if you happen to have them there

oblique mist
#

This is the command I tested with UE4.27:

AutomationTool.exe BuildGraph -target="Make Installed Build Win64" -script=Engine/Build/InstalledEngineBuild.xml -AllPlatforms=false -TargetPlatforms=Win64 -HostPlatformOnly=true -set:GameConfigurations=Development;Shipping -set:VS2019=true

This is the command I'm currently using to test UE5 (I set all the defaults and removed all unwanted platforms in this script)

AutomationTool.exe BuildGraph -Target="Make Installed Build Win64" -script=Engine/Build/CustomEngineBuild.xml
#

This is the command I tested prior to the simpler version above for UE4.27:

AutomationTool.exe BuildGraph -target="Make Installed Build Win64" -script=Engine/Build/InstalledEngineBuild.xml -set:WithDDC=true -set:SignExecutables=false -set:EmbedSrcSrvInfo=false -set:GameConfigurations=Development;Shipping -set:WithFullDebugInfo=false -set:HostPlatformEditorOnly=false -set:AnalyticsTypeOverride= -set:HostPlatformDDCOnly=true -set:WithWin64=true -set:WithMac=false -set:WithAndroid=false -set:WithIOS=false -set:WithTVOS=false -set:WithLinux=false -set:WithLumin=false set:WithLinuxAArch64=false -set:CompileDatasmithPlugins=false -set:VS2019=true -set:WithServer=false -set:WithClient=false -set:WithHoloLens=false -set:WithWin32=false
#

(I successfully auto-built UE4.27 without ios and other platforms using a custom script)

stark basin
#

the first commandline lists Linux nodes for me (I don't have the changes in the script), but that's because you passed -AllPlatforms=false instead of -set:AllPlatforms=false. Unfortunately, variables in the xml cannot be parsed just like switches, you need to preped -set:

#

if I change it to -set it only lists Win64 nodes

#

Also in the second commandline for 4.27 (I'm testing 4.27 BTW), you have one missing -set too (for AArch64)

oblique mist
oblique mist
stark basin
#

yeah, the syntax is finicky. It's best to debug what nodes are going to be executed for a given target with -listonly first

oblique mist
#

Any clues why the required folders are missing? Do I need to add a copy-op to the script?

stark basin
#

what's the commandline for that one?

#

LocalBuilds is where the installe dbuild will be put IIRC

oblique mist
#

right, I know that; the second command above for UE5 (I again manually removed all platforms from the script; I did not remove the DDC lines)

stark basin
#

would you know what node is erroring out?

oblique mist
#

Task [10/11] Build DDC Win64

stark basin
#

no solid idea but maybe you edited the file too much? I see that it tries to copy everything into that folder before running the commandlet:

        <!-- Get our temp dir -->
        <Property Name="DDCDir" Value="$(RootDir)\LocalBuilds\InstalledDDC"/>

...

        <!-- Copy everything to a temporary directory -->
        <Copy From="$(RootDir)" To="$(DDCDir)" Files="#FilteredCopyList"/>
        <Copy From="$(CsToolsDir)" To="$(DDCDir)" Files="#Build Tools CS Binaries"/>

        <Command Name="BuildDerivedDataCache" Arguments="-TempDir=&quot;$(DDCDir)&quot; -FeaturePacks=&quot;$(ProjectsToBuildDDCWin64)&quot; -TargetPlatforms=$(DDCPlatformsWin64) -HostPlatform=Win64 -SavedDir=&quot;$(SavedDir)&quot;"/>

so maybe FilteredCopyList doesn't contain the engine content somehow?

oblique mist
stark basin
#

look for differences between your script and the original, particularly lines that Tag Files with #ToCopy

oblique mist
stark basin
#

TagDDCEngineFiles seems to be tagging the files

#

hehe

oblique mist
#

I will try the listonly command and the default script

stark basin
#

BTW I'm learning about how that node works together with you, I don't normally deal with these scripts.

#

but it sounds like you commented the very line that was supposed to tag the files for copying

oblique mist
#

ah, you think... maybe... I'll uncomment and give it a try

#

@stark basin while that's doing its thing... I figure I might mention: Default__ORPHANED_DATA_ONLY_DmgTypeBP_Environmental_C_0 - I don't know why the editor doesn't crash from a segfault because of that fancy ol' class. 😆

stark basin
#

what's that?

oblique mist
#

🤷‍♂️ ...others here tell me it's an ancient blueprint class in the engine. Well it's SuperClass is NULL and on editor initialization, a function is called on its SuperClass. Normally that should result in a segfault, but apparently not.

stark basin
#

yeah, no idea either. Also, I'm not particularly well versed in BP guts 🙂

oblique mist
#

In the audio editors, init code loops through all UClass objects and calls IsChildOf on their parent class.

#

Thought it was interesting that this undefined behavior never crashed the editor (unless you built it with Clang12)

stark basin
#

IsChildOf probably ends up not needing anything from under this

#

also, there are some (rare and old) UObject functions that check if this is null and return if it is

#

it doesn't need to dereference this and would survive it being null

oblique mist
stark basin
#

(and it is not a virtual function)

stark basin
oblique mist
stark basin
#

might be clang12 is doing something different when seeing a method called from under null this. The standard allows it to do whatever as it's an undefined behavior

oblique mist
#

let me see if I still have the logs...

stark basin
#

time to hit the hay. Thanks for the logs but please don't sweat it as I don't think they are needed (unless you're curious what clang 12 does differently - then there may be an easier way to learn that on godbolt). The change looks good to me, but I'll leave it to our regular process (I'm sure there's already a JIRA with your PR on audio folks' plate).

oblique mist
#

Thanks for your help! I learned a little more about UAT

stark basin
#

You're welcome. So did I 🙂

Is there a macro anywhere to determine if the engine is on UE5 early access vs UE5 main build?

# oblique mist task [10/11]... no errors so far

Did you launched setup.bat with: Setup.bat --force --exclude=Win32 --exclude=Linux --exclude=Android --exclude=Mac --exclude=IOS --exclude=TVOS --exclude=HoloLens --exclude=Lumin -exclude=LeapMotion --threads=2 --max-retries=6 --exclude=Debug --exclude=Templates

#

I never would launch it full as then download size is enormous and i do not need those

oblique mist
hazy moat
#

thats why i have to fight iOS error

oblique mist
#

I’m reluctant to believe that is the case. BuildGraph scripts are XML scripts where you can even tell it to automagically add those “mandatory” color check images.

I can give your command a try, but right now my UE5 auto-build is stuck on another error, which I think has to do with the code itself.

I can compile UE4 with clang on Windows. Something seems off at the moment with UE5’s project generation.

hazy moat
#

good to know, there is hope for future then so clang instead of VS 🙂

oblique mist
#

GenerateProjectFiles.bat -Verbose -Compiler=Clang -CMakeFiles

hazy moat
oblique mist
#

Is the “exclude=linux” also going to exclude linuxaarch64? I noticed that missing in the args

hazy moat
oblique mist
#

If I encounter the error even after using a custom build script, then I would like to track down its dependency.

hazy moat
#

it was weird error as you see that in my .zip i posted, i needed to use fake dummy images to bypass one ios error and in end i had to use that .xml so compilation could finish with success.... and then i got build completed

#

My first goal is to avoid useless platforms from even downloading as it is waste of time and bandwidth and i build minimally as possible too. For example when i would build for Linux then of course first i would allow Linux(removing --exclude=Linux line) to be downloaded from setup or it would not compile.

cedar tree
#

why are there duplicate commits on ue5-main but with different hashes? 🤔

torpid valve
#

where do you see duplicate commits ?

#

oh ok I see few dups

#

the answer is probabaly simples, there are various branches

#

that auto merge between each other

#

and it seems that it got somewhat broken when trying to add new branches to sync with git (;

cedar tree
#

it's odd that the diff shows the same additions and deletions even though the previous commit has the same

#

shouldn't the diff be empty then? 🤔

torpid valve
#

it's probabaly because how p4 -> git sync work

#

idk

#

ue git repo is just dump from various branches directly

magic isle
#

worth opening pull requests for crash fixes on ue5-main?

stark basin
# magic isle worth opening pull requests for crash fixes on ue5-main?

No. In general looking/working in Main isn't really worth it. By the time it gets to the release from the Release branch it will get multiple QA passes and other fixes.

If Main is broken due to an obvious (like, on startup) crash or a CIS error, it probably means that people inside also ran into it. It may be very well fixed already since p4->git mirror has a delay of several hours. So filing a pull request will create a JIRA that will be likely addressed by someone in several days, when the original problem is long gone

magic isle
#

it's a minor fix that causes a crash on exit

#

er, minor issue

#

I don't want to bother if nobody looks at pull requests for main, though

stark basin
#

the exceptions to this general advice would be:

  • if you run on a platform that we don't dogfood enough (like Linux)
  • if you are compiling with an uncommon compiler (e.g. too new or just different, like icl)
  • if the crash is not obvious to get to and may be missed by QA (then please include the repro steps)
  • if you think that it is not getting addressed in what you believe is a reasonable time :-)
#

crash on exit may be worth fixing. Those tend to persist for some time, unless it also happens in a commandlet/cooker

#

(then it is obvious as it fails automated jobs)

magic isle
#

yeah it's timing sensitive so it may well slip by QA, might get caught by static analysis

#

need to check the validity of calling .Pin before using it

#

I'll just keep it in my local fork for a while until it either starts conflicting or we start seeing UE5 releases

stark basin
#

sounds good

crimson granite
#

Anyone else getting SEE ambiguity errors?

crimson granite
#

Yes, thank you

#

Also, my game module fails to load with CouldNotBeLoadedByOS

#

Been stepping through the code

#

FModuleManager::Get().LoadModuleWithFailureReason() returns NULL

#

Not sure what could cause this

#

Looks like maybe it cant find or load it...?

#

Missing import: UnrealEditor-Party.dll Missing import: UnrealEditor-TimeSynth.dll

#

Hmm

#

Wonder why it can't find those

opaque phoenix
#

is the auto exposure bug fixed?

ashen kiln
#

afaik no

limpid light
#

@crimson granite using the ACF plugin by chance? I fixed an issue in that source due to recent UE5 changes. Its not the engine code that has the compile error but code that is calling that function. In my case the plugin code was passing an int32 into a function that should only accept float.

#

To fix it, I changed this line
MaxComboCount = FMath::TruncToInt(FMath::RandRange(combatBehav->MinMeleeComboAttacks, combatBehav->MaxMeleeComboAttacks));
Into this
MaxComboCount = FMath::RandRange(combatBehav->MinMeleeComboAttacks, combatBehav->MaxMeleeComboAttacks);

@hazy moat Figured it out. I was able to replicate your error:

Cannot write to the output file "M:\UnrealEngineFive\Engine\Source\Programs\AutomationTool\IOS\obj\Development\IOS.Automation.Properties.Resources.resources".
Could not find a part of the path 'M:\UnrealEngineFive\Engine\Source\Programs\AutomationTool\IOS\Resources\GreenCheck.png'.

ERROR:   Failed to build: M:\UnrealEngineFive\Engine\Source\Programs\AutomationTool\IOS\IOS.Automation.csproj
ERROR:   Failed to build: M:\UnrealEngineFive\Engine\Source\Programs\AutomationTool\TVOS\TVOS.Automation.csproj
 build complete.

I attempted to build AutomationTool itself and ran into the same errors.
In UE5.sln, you will notice that IOS.Automation etc. are added as dependencies to AutomationTool.
UE5.sln is generated by UnrealBuildTool, which means these dependencies are being added dynamically.
Deleting the IOS and TVOS folders under Engine/Source/Programs/AutomationTool fixes these errors.

Don't forget to check how many processes are used to build your code. I have 5950x with 32 threads and 32GB RAM. I am not sure if this system was also in UE4 but UE5 automatically checks your available RAM per core and lowers the process count accordingly. UE5-Main expects ~1.5GB per process, so it was never using all available threads. I noticed only when the builds were too slow. This is also affected by current free RAM, in my case Rider was parsing UE5 source for the first time (therefore taking A LOT of RAM) and the compilation started with just 4 processes on 5950x o.O

#

I will be updating to 64GB

solid cypress
#

I did it for 32 processes and my OS got stuck, lol

#

even windows explorer was unusable

#

but with 16 processes it was still okayish

minor axle

how can fix that?

@quiet kraken Well I did attempt to use a non unity build. Not sure if it is because I am using DebugEditor (haven't tried DevelopmentEditor yet), but the engine itself would not compile

quiet kraken
slim violet
#

I love resharper for C#

#

currently I am not really liking it too much for unreal projects

#

because of the billions of red squiggles it adds to everything while visual assist x only adds red squiggles that are legit (with about maybe a 4% error margin)

#

you suggested that I turn off unity builds for my game project, which I did

#

to see if it would compile

quiet kraken
#

OK, then I'm remembering correctly. Disabling Unity builds for Game doesn't affect the Engine build though.

#

what errors do you get?

slim violet
#

hundreds of errors. I don't have them up at the moment (switched back to a unity build), but I can get htem

#

*them

#

lots of errors in engine source files

#

also, I know that editor text colors can be adjusted, but is this really the default color scheme for resharper and C++?

#

That hurts my eyes

#

not sure if I am the only one or not

#

that light blue text specifically

solid cypress
slim violet
#

Ok

#

Yeah and you can customize the color of each object type. I was just curious if it was really the default

#

or if something was broken on my end

quiet kraken
solid cypress
#

I see, I expected this is from Rider For Unreal Engine. Could be that it is not in VS + Resharper C++.

#

makes sense

quiet kraken
slim violet
#

I primarily use DebugEditor - it had been built prior

#

I'll check on the .build.cd

#

*.build.cd

#

cs - I'll type it out right eventually

quiet kraken
#

wait what. I'll need to check it closer. I'm pretty sure you can switch off Unity build in Target.cs for game that uses binary/EGS version of Engine.

#

huh... I'm pretty sure that's a bug. I'd be pretty pissed of if I'd be forced to rebuild my engine.

#

... I have so many questions now. Hate this server's convos, they always happen when I'm way past my curfew and falling asleep. ><

Why compiled ue5-main engine folder comes at 200gb? Isn't that excessive?

I think this channel is more appropriate

gleaming leaf
#

probably all the symbol *.pdb files that you actually only need for debugging

eager hedge
#

it's not excessive at all, pretty standard for how big the engine is.

slim crater
#

Isn't the epic launcher ue5 like quarter of the size?

eager hedge
#

You can delete intermediate artifacts if you want which will cut down on the size, but it'll result in many things needing to be rebuilt if you try to build the engine again.

#

The launcher version of the engine doesn't include any intermediate artifacts from the build.

#

It also doesn't include debug files by default.

slim crater
#

I'm only looking for one build to start using the new modeling tool with the grid, that's like my only reason to build it

#

Also what kind of machine can build it in 10-40 minutes? Took over 7 hours for me, on 3070gtx 32ram and some one of top cpus

#

Does anyone know when the new grid modeling tool with ue5 is planned to be released in epic launcher?

oblique mist
slim crater
#

I took the 10-40m from official documentation, but it just seems unbelievable

#

I've had it on ssd

oblique mist
slim crater
#

I guess for ue5, that's in laboratory conditions, just like car benchmarks are made

eager hedge
#

not really, ue5 isn't considerably different from ue4

#

it heavily depends on specs. SSD is good, 32GB RAM is good depending on thread count. Which leaves the question of your CPU. And of course something could just be wrong with your install but we have no way to tell that.

slim crater
#

I just followed the instructions, run the .bat to download more stuff, run it in vs2919, make sure it's editor and 64 and that's pretty much it

#

I would stick to epic build if it had the new grid modeling tool

#

But the official version doesn't have it

plain lintel
#

If its taking the 7+ hours on good machine, then you might have a misconfigured Incredibuild screwing things up. I know originally it was taking me MANY hours until someone suggested it, I checked the very start of build logs, saw it gave 1 casual warning, then went to uninstalled incredibuild, and then it built SO MUCH significantly faster (and I have a far weaker computer than you). Most people don't likely have the setup that'd benefit from incredibuild (distributed network of computers that can help compile), so it shouldn't really be installed unless you know exactly what you are doing. (Includes both UE4 and UE5)

opaque phoenix
lofty idol
#

10-40m for UE4 on the docs is from years ago iirc

#

earlier versions of the ue4 used to compile faster (with some variations ofc)

#

you can still get compile time to around that timeframe, but you will need to fiddle with your build config and avoid building the whole engine etc

#

somewhere along the line the compiled size of the engine also blew up

plain lintel
#

@opaque phoenix go to your visual studio installer.
and go to 'modify' and look at individual components, you should uninstall incredibuild.

I am sure it's possible to get it to work correctly, but I've never had luck and had multiple people recommend un-installing it. When it was installed, my machine would only use 1 core to compile unreal, and after uninstalling it, it'd use all my cores.

TekuConcept: Deleting IOS and TVOS folder bypassed first compile errors 🙂 compilation began, lets see if it finishes too. Ca 1.6-2h..........

hazy moat

TekuConcept: When i tried directly feed to automationtool.exe those commands instead of RunUAT i got weird hotsfx.dll or whatever error(lots of days ago when i tried). RunUAT runs fine. Weird, dont know but at least it works 🙂

TekuConcept: Nope still ios error, just in the end this time, same like it was with dummy image hacks where it reached almost to the end and then i inserted custom InstalledEngineBuild.xml and then it finished. Now i try with this way: Deleted ios and tvos folders again and when compilation fails(building as we speak) then i use custom InstalledEngineBuild.xml to finish building.

hazy moat
#

TekuConcept: Yes, build again was successful if i replaced this InstalledEngineBuild.xml with official one and IOS garbage was bypassed. Sadly deleting those folders only byspass compilation error when beginning building(basically it was same effect by dummy images).

I do not know, for me IOS trash was around 2gb but idea is that why i need this apple stuff. Glad that there are hacks that bypasses that beautifully. And when running setup.bat together with .gitdepsignore then download is even smaller. My crusade is to build artist edition of Editor without unneeded stuff and build speed increases too. I built 46ad7a with anti iOS hack and it works very well. Love the new category filters on selected objects 🙂

the nanite page puts VR and forward shading in the not currently supported list which is what confuses me. Not currently would mean it would do so in the future right?

I doubt epic would make nanite work with forward shading, not unless they make a vr mode for fortnite or something

anything that they don't actively dogfood usually end up stagnating

# opaque phoenix where can I find this incredibuild? My builds also take 6-7 hours. 16 gb ram i7 ...

Incredibuild cause serious problems with UE btw, just fyi. For example in my case it blocked shader compiling process and even with VS Installer I was unable to remove it. I contacted their support team and together we wasted one week only to find out 'how can we remove the incredibuild' so I could continue compiling shaders in UE (though their support team was one of most nicest, among in the other companies I've seen) 😄

I also mark my changes clearly with comment blocks, with a START and END comment along with a comment on what the change was about

Not sure if that's really needed if you're using git, git blame does the same thing.

Also adding those kind of comments makes it harder to merge changes from upstream.

Can anybody say if 70 minutes is the expected time to a first build of ue5-main in a 5800X? If it isn't I can't say what I'm doing wrong. Unity build is on and I'm only building Win64

stark basin
stark basin
#

make sure you have at least 2 (better 3, 4) GB per core. Also, if building UE5-Main, there was a recent change that limited number of jobs to physical cores only. That was supposed to help people running OOM when building on 128 core CPUs, but in practice it is probably not beneficial and will be changed. You may want to set ProcessorCountMultiplier to 2 if you see UBT only using 8 cores on 5800x

strong agate
#

Is the UBT supposed to be the cl.exe in task manager? Because that's the processes that most take resources and I see only 7 of them

stark basin
#

this is the compiler itself

oblique mist
#

@stark basin I wonder why UBT in UE5-main no longer accepts clang.

stark basin
oblique mist
# stark basin Whoa, what do you mean?

In UE4, I could run GenerateProjectFiles.bat -Compiler=Clang and then UBT would use clang-cl instead of msvc-cl.

Running the same command for UE5-main works, but the builds still use msvc-cl.

#

It’s like the msvc compiler is forced for engine builds in UE5.

stark basin
oblique mist
#

Figured it out by inspecting GenerateProjectFiles.bat and UBT sources 😉

stark basin
oblique mist
#

this is the way

you can try posting that on the AnswerHub or forum if you want UBT folks to chime in. Or just wait, UE5-Main is pretty far out in the future, maybe it will start working again :)

# stark basin so... we're hooking up new branches to github, once that is done, the mirror wil...

I understand releasing new branches takes as long as it needs and this is not about being demanding but rather a respectful inquiry: I was wondering if there are any estimates about how long will it take for the ue5-release branch, or any branch with UE 5.0 development (not 5.1), to become public on GitHub. Will it be days, weeks or months from now? Any clues would be very appreciated for planning a current educational project we are working on. Thanks!

ashen kiln

I second to that question, especially now ue5-main is getting post-release updates, it doesn't make much sense to get latest commits after version was increased to 5.1. So, we're in kinda limbo state where we should wait for a 5.0 branch is made public.

Curious, I dont see a pinned message so wondering if anyone has any info on this, I dont remember UE4 compiling limiting my # of processes based on memory (1.5gb free per compile process) but UE5 does seem to do that. This limits me to less than my true # of cores when compiling on this laptop. Anyone know if this is a VS thing, UBT thing, or something I can change so I can get more than a couple cores compiling on this machine for UE5 source. EDIT: and I scrolled back far enough to find some valid info on this. might be nice if some of the changes were in the pinned messages 😉

this one is just nice since it basically lets your compiler go back to how it was before the changes and have no limits lol

Wanted to build UE5 main branch from github and got some rebuild issues.
Originally started a first build and it failed because I forgot that building UE from source requires a lot of storage space.
I moved the folder to another partition with enough space and started a rebuild to try and resume the prior build.
After some time, it failed with these errors

What would be a good way of fixing this error without having to do a clean build from scratch again?

#

P.S. running latest version of Rider for UE

eager hedge
#

Fix the errors and do a normal build?
Not sure why you're rebuilding every time.

#

Rebuild does a clean which means that everything has to be built again. Building normally just builds things that changed/didn't succeed previously.

spice cedar
#

ooh

#

thought rebuild and build were opposite 😅

That's... you know, I'm so used to that terminology because it's pretty standard across programming as a whole, but I can see why that might be confusing to someone who isn't familiar with it.

the docs on using commandlet to use world partition is a joke

#

it leaves out a very important step if you didn't understand...and in their example they point to a ue4 4.26 lmao

#

Who is writing this stuff

limpid light
#

World Partition is working just fine in latest main, I'm using it. The settings under world partition got renamed, so be sure you are looking in the right place.

#

Scroll up a little bit and you can see me answering this question for Gatox earlier today

#

As for the commandlet, its very finicky. The main thing that a lot of people get stuck on is how to provide the map name parameter, but it has to be without any paths and without the .umap ending.

#

For reference:
"<full path to UnrealEditor.exe or UnrealEditor-Cmd.exe>" "YourProjectFile.uproject" MapNameHere -run=WorldPartitionBuilderCommandlet -Builder=WorldPartitionHLODsBuilder -AllowCommandletRendering -log=HLOD_log.txt

Remember to wrap the full path with quotes, otherwise spaces in the path will break your cmd

#

If anything breaks, you can check the HLOD_log.txt for details

tranquil zenith
tranquil zenith
#

it cant find the map

#

I mean it should be obvious idk what I could possibly be doing wrong

#

and the project location just adding the projectName.uproject doesn't work it has to be the path to the project. (Unless there's something I an overlooking..because how would it know where the project was just looking at the engine folder??) the map name I put as just the map name. I thought it was to do with it being in some subfolder so I put it directly in the main content folder but still nothing so I have no idea

tranquil zenith
#

Ya no matter what I do it says unknown level 'levelname'

#

Is there something that has to be done in engine first

limpid light
#

@tranquil zenith can you paste the exact commandline you are using, its probably some small detail you are missing 🙂

#

Also, if you use the commandline example I pasted a detailed log file is created, so you can probably find a more detailed error there

tranquil zenith
#

"C:\Users\ProjectStorm\Desktop\UE5_MAIN2\Engine\Binaries\Win64\UnrealEditor.exe" "C:\Users\ProjectStorm\Documents\UnrealProjects\partitionTest" -run=WorldPartitionConvertCommandlet Map -Builder=WorldPartitionHLODsBuilder -AllowCommandletRendering -log=HLOD_log.txt

I notice other people have the .uproject at the end of theirs but if I do that it gives me "failed to open desciptor file" error..which if I need to add the .uproject at the end thats probably the issue then.

limpid light
#
  1. second parameter should end in .uproject
  2. The mapname should be the 3rd parameter
#

Try this

"C:\Users\ProjectStorm\Desktop\UE5_MAIN2\Engine\Binaries\Win64\UnrealEditor.exe" "C:\Users\ProjectStorm\Documents\UnrealProjects\partitionTest.uproject" Map -run=WorldPartitionConvertCommandlet -Builder=WorldPartitionHLODsBuilder -AllowCommandletRendering -log=HLOD_log.txt

tranquil zenith
#

tried that way

#

that was the first time

limpid light
#

This is exactly what I use 🙂 Is your level really called just "Map" ?

tranquil zenith
#

if I include the uproject at the end I get a failed to open descriptor file (which is likely the issue then)

#

and yea I am just trying to get this damn thing toi work lmao

limpid light
#

ah sorry I realized your "partitionTest" is a folder, so this should be:

"C:\Users\ProjectStorm\Desktop\UE5_MAIN2\Engine\Binaries\Win64\UnrealEditor.exe" "C:\Users\ProjectStorm\Documents\UnrealProjects\partitionTest\partitionTest.uproject" Map -run=WorldPartitionConvertCommandlet -Builder=WorldPartitionHLODsBuilder -AllowCommandletRendering -log=HLOD_log.txt

#

Run this, and take a look at what is in HLOD_log.txt

tranquil zenith
#

ya no good same thing

limpid light
#

oh another big problem

#

you are using the wrong commandlet

#

This is the correct way

"C:\Users\ProjectStorm\Desktop\UE5_MAIN2\Engine\Binaries\Win64\UnrealEditor.exe" "C:\Users\ProjectStorm\Documents\UnrealProjects\partitionTest\partitionTest.uproject" Map -run=WorldPartitionBuilderCommandlet -Builder=WorldPartitionHLODsBuilder -AllowCommandletRendering -log=HLOD_log.txt

You should have been using "WorldPartitionBuilderCommandlet" instead of "WorldPartitionConvertCommandlet"

tranquil zenith
#

unknown level 'Map' .. :.....

#

idk

limpid light
#

What is the name of your Level? did you really name it Map.umap ?

tranquil zenith
#

100% it is called map 100% it exists lol

#

I made a fresh project..created the level just to test this conversion thing

#

because ther was no option to just enable in engine that I can see

limpid light
#

Where did you save it? Is it under Content/Map.umap ?

#

I did that

#

but I will do it again

limpid light
#

and you did change the order? so the map name is now the 3rd param? it was wrong in your original cmdline

tranquil zenith
#

yea I am running it as you showed me

#

new level still nothing. I dont get it

#

makes zero sense to me

#

making me question my sanity lmao

#

I delete binaries and ran the commandlet again.. ..its..doing something... .......I think

limpid light
#

only other thing I can think of is your map being configured to use world partition and set for 1 file per actor?

tranquil zenith
#

I havent done anything to it I only created the level and changed nothing

yeah, my pc is like 5-7 years old at this point. I wanted access to stuff like the cubegrid(?) new modeling tools which look fantastic for actual level design (as they're not in the alpha release yet), but i might need to just wait cuz i've blown alot of time on this crap.

i'm listening

I figured it would be in pinned messages but it wasn't 🤔

maybe someone else here knows more

UE5-MAIN branch (almost) daily build with results!

Do you want to compile ue5-main but afraid it might compile or not? Fear not young warrior for I come to rescue. Well, I’m not gonna give you access to super computer but I decided to compile ue5-main branch (almost) everyday (if new changes are available) and post the results to my new Unreal Binary Builder Discord I just created. There you wil...

oh wait, I'm not sure if he distributes the binary..

🤷‍♂️

that would be pretty cool but I assume there is some legal obligation

#

yea that crept to my mind too

quaint plover
#

Yeah, i mean it's good to know that some of these commits i was spenting a day trying to compile could fail. so i'll def keep that inmind regardless.

#

but yeah fuck it i'll just use the released alpha if i really care, new tools are neat but i'll deal. Much appreciated.

Ran into a roadblock converting my project to 5.0.0 Early Access 2. My game relies on the Physics Constraint Component, and it is missing functionality from the chaos physics engine. Led me to find this lol

Mass can export dependency graphs

I wonder if those ass to world updates are faster or do they still run into the fact that updating component locations is slow

static copper

you save a bit on icache there but if they are moving scenecomps

torpid valve

i probabaly shouldnt tell you, but it should be obvious

#

;d

there is demo in the works showcasing what mass can do

#

sick

#

right now the representation stage group is setup wrong somehow

#

I have no clue what it really wants

torpid valve
#

the amount of simulated entities is in ten of thousands

#

but only some of those entities are "agents" <- which is word for entity with assigned actor

#

that means that yes actor update is still slow

static copper
#

yeah, the idea still seems to be to have entities that become actors when they need to do anything besides moving around

it's a start!

ive been thinking how to integrated ability system with Mass recently

coz i want to do real hero game, where you can apply dots to 100 enemies

static copper
#

almost certainly you have effects as entities

torpid valve
#

haha

#

that one solution

#

i thought about different

#

you can have single manager actor with ASC

#

which will map effect to entity

#

after all you only need to clear id of effect

#

once effect tick you iterate over assigned entities and do something

With recast you need multiple nav meshes for agents of different sizes

odd

#

I mean, I imagined the polygon edge length would've been readily available in the data 😄

torpid valve
#

you need different size navmeshes for agent to fit the triangle size

or rather voxel

cedar tree
#

I thought you could just "slide" the edge verts towards the edge center by the radius of the agent during path finding

#

and then check if the path is still open

A question for people using UE5 in production on small teams: How do you keep up with engine updates? Do you have GIT forks/custom builds and you add commits by hand when something interesting comes along, constantly checking to ensure that it doesn't break something you added? Do you do you make plugins for your modifications and always update to the latest "stable" ue5-source branch version that builds? I'm a tech artist trying to learn a bit more about this stuff but I'm unsure about were to begin. Cheers.

Also, I've read through #ue5-engine-source and #ue5-general and Sequencer / Distance Field Shadows seem to be completely borked (so I imagine Lumen / AO and everything doesn't work either) in the most recent ue5-main commits?

ashen kiln
#

we stopped updating after 5.1 bump commit is made into ue5-main, currently waiting for 5.0 branch to continue updating.

gilded pecan
#

So waiting for backports from 5.1 to 5.0-main ?

ashen kiln
#

Nope, just 5.0 branch to get published on github

#

We're currently at 5.0 era of ue5-main

gilded pecan
#

I see.

ashen kiln
#

After it's published, I will just pull that branch and reconcile again in perforce. should be easy.

gilded pecan
#

And is anything other than what I mentioned currently DOA / in horrible shape on ue5-main ?

limpid light
#

We jumped on the latest in main (5.1), which means that I'll be stuck with a less stable 5.1 until that gets officially published.

gilded pecan
#

That seems like a very scary prospect, considering the fact that 5.0 is probably 3-5+ months away (QA'd launcher version)

oh crap

limpid light

back porting assets is a PITA, I recently went through some of that and easiest way was to re-create the assets in an older version manually

opaque phoenix
#

fortunately the important stuff is in cpp and I was just starting up on my project

limpid light
#

cpp is fine 🙂 only the .uasset will give you problems

opaque phoenix
#

I will have to rebuild my behavior trees :(

limpid light
#

or just do like me and stay on 5.1 for some time 🙂 when 5.0 ships, the ue5 main branch will have all that code too, just with more and a bit less stable

opaque phoenix
#

how long until 5.1 ship then? 3 months after 5.0?

limpid light
#

nooo idea

opaque phoenix
#

based on usual patterns?

limpid light
#

based on older release cadence, I'd say around 4 months after 5.0 release

opaque phoenix
#

rats

#

but the current binary version has not been updated for a while

limpid light
#

Epic really needs to get the 5.0 release branch, or better yet preview 1 out soon 🙂

limpid light
opaque phoenix
#

how are current studios managing who are already in production?

limpid light
#

Some have access to Epic's Perforce server and pull from branches there, some are taking more risk and using main branch directly.

opaque phoenix
#

perforce?

limpid light
#

The source control provider Epic uses internally

#

UE5 licensees have access to that instead of Git. Thats for studios that make a custom deal up front on royalties and fees

opaque phoenix
#

so that is even more updated?

limpid light
#

Github usually lags behind around 4 hours, but it doesnt have all the branches that are available on the Perforce server.. including the 5.0 branch where that release is being stabilized now.

opaque phoenix
#

hmmm

#

how much of a loss am I at if I decide to go back to preview? At least vs 4.

limpid light
#

dont go back to preview, its... bad 🙂

opaque phoenix
#

so I have to wait almost another year then 😐

#

compiling has been a nightmare with its duration already

limpid light
#

My plan is to pull in changes from main every now and then, or when a feature or fix gets posted that I need.

opaque phoenix
#

so anything worthwhile lately?

#

I am kinda new to the engine source (got in after our team needed a dedicated server build)

limpid light
#

a lot of stuff 🙂 best source is this channel, so scroll up a few weeks 😄 ECS system, new AI system to name a few things

I'd say do not expect 5.1 until Q3 2022

Rubbing hands eagerly, waiting😋 ...any info when landscape starts to join with Lumen GI system?

#

is it matemathically hard to do?

limpid light
#

Dots isnt all bad 🙂 jobs system and Burst compiler are truly good 🙂 the ECS part.. in constant flux with no end in sight 😛

#

I believe when they started .NET wasnt really on the SSE optimization path?

#

a lot has happened in .NET in the last few years, some low level optimizations and things like Span<T>

#

I know Unity is considering moving to a new .NET runtime, but that seems like a huge change...

opaque phoenix
#

I dont really see any real direction in Unity's process since 2018. That storm of what is production ready and what is not. They introduced so many things but did not really show commitment or give a roadmap for it being prodcution ready.

One thing I really appreciate Epic does. It tells you what is deprecated and what is not clearly and it gives you a proper alternative, at least from how I saw niagara being handled

hazy moat
#

For me biggest thing about Unreal is that you have full code, it is proprietary but at least whole planet can access it , with Unity you have in mercy of Unity to modify or fix things. Personally i am **afraid **of learning closed things that can rob big chunk out of your life if they decide some changes that shuts it down(catastrophe, huge change or whatever you can think).

#

Yeah you could get Unity source..... if you rob a bank, win jackpot, mine diamods or gold or mine Bitcoins with huge farms..............😛

#

It is worth to learn Unreal even if it takes/wastes/benefits half of your life.... at least i think so personally

yes, If I remember correctly, core of the chaos is still developed on UE4

there are not that many chaos commits in ue5-main

indeed

#

seems like trivial errors

solid cypress
#

can somebody elaborate on why is it possible for these duplicate git commits to exist? I know from where these are coming when Epic is duplicating its P4 but I don't get how git can live with it. I would expect git to enforce consistent repo and these commits seem to be against any source control logic, especially because both commits are Add for same lines.

#

I would atleast expect that the second (duplicated) commit will show something like "no changes" or remove and re-add same lines. But it acts like the previous one did nothing.

#

I suspect it is related to commit parents because duplicated one has the first one as parent

...as a world builder learner, lighting, texturing etc.. for me at least 5.1(ue5-main) is much MUCH more stable than EA2. Just a observation and applies only from my perspective, i do not touch high complexity stuff so much as i do visual side of things more.

You need at least VS 2019 afaik. I was getting compiler errors with ue5-main on a computer that had some weird leftover registry key that forced it to use an older C++ compiler.

Question about a fresh compiled version of ue5... I am getting a UnrealBuildTool failure. It seems to not be able to find the F:/UE5/UnrealEngine/Engine/Binaries/DotNET/UnrealBuildTool.exe but the files are put into the F:/UE5/UnrealEngine/Engine/Binaries/DotNET/UnrealBuildTool/ FOLDER.

debugging already done:
0. clean/rebuild

  1. rebuild only the UnrealBuildTool
  2. move stuff around sketchy like

On the rebuild that seems incorrect

Which then when 'Generate project files for client repos' I get Building UnrealBuildTool in F:/UE5/UnrealEngine...

# opaque phoenix Rider does work but keeps give the starvation errors

I'm sorry I'm not familiar with the term "starvation error". Are you referring to the "Not enough memory" popup?
And you've mentioned "Rider plugin", what plugin are you referring to? There are 2 plugins:

  • RiderSourceCodeAccess (bundled in Unreal Editor, adds option to select Rider as your code editing tool)
  • RiderLink (bundled in "Rider for Unreal Engine", you install it by selecting "install RiderLink plugin" option in "Rider for Unreal Engine". It provides few extra features but is not required for the majority of functionality of "Rider for Unreal Engine")
opaque phoenix
#

I need to check again on the plugins after I get bacj from work and the starvation error is likely the memory error (strangely VS works fine).

ashen kiln
#

@quiet kraken isn't that issue related with udp/tcp communication between riderlink & unreal?

"starvation" sounds like that.

I have come to the conclusion that 16GB is no longer enough memory to compile UE5 on newer CPU lol

i'm noticing that during the linking part of a source build (which seems to take the longest), it barely uses any of my system resources. Is this expected behavior?

i would be interested too, what are runuat commands?

This is my current RunUAT chain that works and finishes Editor building

I have wondered how to disable plugins aka exclude from compiling at all

gleaming iron
#

You can add "DisableEnginePluginsByDefault" : true to the uproject file. Not tried with UE5 but I'd assume it's still there.

#

There are a few you'll need to explicitly enable to make the editor usable, but it's the simplest way I've found to cut out the junk.

opaque phoenix

interesting. So basically, trick the IDE into compiling only what is needed 🤔

Not sure it's a trick. More just one of the few settings that actually works and does what it says.

# ashen kiln I just played around with Horde, installed server and an agent, but have no idea...

Epic confirmed it is also for third party and some studios are already using it. It looks less intuitive compared to typical CIS because there is very little config on the web. That is also a good thing. You need to configure it in json. There is probably no good example of that, so you will need to find fields in C# and add them to default (almost empty) config. I am sure Epic will eventually provide examples and docs but at the moment they can not talk about it because it is unannounced thing (just like most of ue5-main stuff).

#

In the config you will need to create your project, configure perforce, agent types used by this project, create templates for your BuildGraph scripts and optionally also create schedule, so that builds start automatically

#

on the web you will need to configure your agent pools

#

windows server limitation is indeed sad as (I believe) it is more expensive to get windows server hosting. However, it is at least much easier to setup.

hazy moat
gleaming iron
#

In the case of a project linked to a source-built engine, if you build the project target with this value set, then it will build the engine minus all plugins.

#

If you're only building the editor target itself, I don't know if there's an equivalent.

ashen kiln

I wonder if they'll update that with latest source 🤔

or from the name, they're probably testing git mirroring for the release engine branch, which is expected soon.

I just manually changed the version in the uproject file

it was a cinematic project so no major logic, so maybe that's why it worked

it opens, but assets that have since been saved with 5.1 wont

the project file is just the initial gate, the assets themselves will not load if assets were bumped in versions

as long as you dont re-save in newer version the format stays unchanged

This is what I use that has worked. Only Windows
RunUAT.bat BuildGraph -target="Make Installed Build Win64" -script=C:\Users\x\Documents\UnrealEngine\Engine\Build\InstalledEngineBuild.xml -set:HostPlatformOnly=true -set:WithDDC=false -set:SignExecutables=false

copper cables that are over 40 years old

#

ah, gotcha

hazy moat
#

i just do not need iOS and i do not download that garbage at all if you see and only tiny tiny thing inside that xml is that causes errors(official InstalledEngineBuild.xml)

#

thus according to my plan, every time it stops on error, i replace it and build is resumed&completed

#

in beginning i have 2 tricks to avoid those errors, deleting 2 folders or placing dummy images, both work

#

just fyi, I do advise again using testing/staging branch3es

hazy moat
#

i just prefer deleting folders

#

these are only for merging changes between release and main

solid cypress
#

so there is no need to experiment anymore

solid cypress
#

not early access. This will be eventually final release when the time comes

lofty idol
#

is it production ready by any means?

#

or at least for starting a project for later release there?

chrome ingot
#

not until they say it is

#

and no its not

#

and in other words, no

#

things can change, if you are ok with fixing them yourself or having things break or not working then you can use it.

#

it looks like 5.0 branch fixes the weird motion blur issue with ue5-main, so thats good

lofty idol
#

by things can break you are talking only about new features and that UE4 features are stable as is?

chrome ingot
#

nope, old features that are being upgraded could be broken

lofty idol
#

thats a bummer

chrome ingot
#

things being replaced like physx

#

5.0 is the start to 5.0 release, once they lock down for previews and release then you have a better chance of making a product with the least amount of issues.

#

with that said you might run into 0 issues using 5.0 or even 5 EA right now shrug

lofty idol
#

I have noticed on the EA that theres heavy fps drops

#

even with most new features disabled

#

compared to UE4

#

so its quite hard to just start there in general I guess

#

but its cool to know that the release is getting closer

#

thanks for the info

chrome ingot
#

more than likely even 5.0 release will have changed performance compared to 4 😦

lofty idol
#

that could be the case but

#

Unreal engine 5 has insane potential for long run performance maintaince

#

compared to UE4

#

Nanite and world partitions can make a huge difference on large scale projects

#

or detailed ones

chrome ingot
#

thats the idea for sure 🙂

lofty idol
#

while UE4 is stuck with an expected performance delivery

#

I believe even with the release of UE5 some developers will benefit more using UE4

cerulean salmon
#

hey what branch do I PR against for UE5?

lofty idol
#

if nothing UE5 offers makes a huge difference for their own final rpoduct

#

but its still cool to have both as options

solid cypress
#

and some PRs are getting accepted

#

but I did not see any official info

cerulean salmon
#

thanks

solid cypress
#

if 65536 is not crashing, will it crash if you set it even higher?

cerulean salmon
#

I don't have CBs larger than 65k

solid cypress
#

I see

cerulean salmon
#

even if it doesn't crash 65k is the official limit in DX12 - some IHV drivers might let you (seem like you can) get away with it but that's just bad practice at that point

#

what's so weird is that 4096 bytes is so tiny I really don't get how this never got caught - unless of course I'm wrong, which I really want to be tbh :P

solid cypress
#

Can you try to run DX11 with that change

#

I suspect it will crash

# 
void FWinD3D11ConstantBuffer::InitDynamicRHI()
#

has check

# 
check(MaxSize <= D3D11_REQ_CONSTANT_BUFFER_ELEMENT_COUNT && (MaxSize % 16) == 0);
#

D3D11_REQ_CONSTANT_BUFFER_ELEMENT_COUNT is 4096

chrome ingot
#

his change is to the dx12 rhi so hopefully it wouldnt crash with that change
