either way

it was worth so and i would do it again without blinking

#

especiallyy now, that I work mostlyy from home

devout iron May 15, 2020, 3:29 PM

#

hm yeah that makes sense

#

i7, 6 core, 2.2GHz, 16GB RAM

#

probably need to add some RAM

#

I know it's not the best machine but I feel like my engine build times drastically increased in the last few months

#

It usually took 1-2 hours tops, and 2 hours was a busy day

unreal wraith May 15, 2020, 3:44 PM

#

I have that amount of ram and system builds are like 15-20 minutes. My CPU is the ryzen 5 6core 3600 which was the biggest upgrade from 1-2hr builds on my last system

devout iron May 15, 2020, 3:52 PM

#

it's definitely my CPU :/

#

it's just interesting because something between 4.21 - 4.24 really seems to have changed the experience for me

#

I basically have to leave the build running overnight to ensure I can work in the morning

#

granted it should be a one a time thing every few months at most but I do have a few engine versions around for specific hardware + plugins...

full flare May 15, 2020, 6:48 PM

#

I'm trying to build a source of the 4.25 engine so I can play around with the Chaos feature... but I'm getting an error before I even reach VS2017... could someone lend me a hand please?

#

It's when I run GenerateProjectFiles.bat

#

#

Odd thing is I don't have a drive M:...

#

Correction... I see that I do now... my computer relabeled one of my drives... odd...

#

ok... I've downloaded the source from Github... I've ran the setup.bat file...

#

says I'm suppose to run the GenerateProjectFiles.bat second...

naive fossil May 15, 2020, 6:55 PM

#

that is right

full flare May 15, 2020, 6:55 PM

could anyone lend a hand on what I'm doing wrong... am I missing step

You have VS 2017 Enterprise?

full flare May 15, 2020, 6:59 PM

#

then I was told to copy the ChaosDestructionDemo to the root of the folder I unzipped the github files to... which I did then run the GenerateProjectFiles.bat

naive fossil May 15, 2020, 7:00 PM

#

i think that you should genertae engine project files

#

then build engine

#

after that you can use proejct

full flare May 15, 2020, 7:01 PM

#

📎 unknown.png

#

so yes

#

online says this...

📎 unknown.png

#

Then I found another section that reads like this...

📎 unknown.png

#

hence why I'm looking for help outside the docs I've found... looking to someone who's built it and got it to work... that can fill me in on the missing steps... fill in the gaps as it were...

#

So ANY help at this point is good help

#

because on the one screenshot it says to run the one and then right after run the other...

#

the second screen shot shows (If I read it properly) to compile then run the GenerateProjectFiles.bat.....

#

@naive fossil Thoughts?

naive fossil May 15, 2020, 7:09 PM

#

oh with this chaos demo it seems to be sth different

#

so I will keep forum post

full flare May 15, 2020, 7:10 PM

I'm sorry I'm not following... Meaning?

naive fossil May 15, 2020, 7:10 PM

#

so you unziped UE source code and unzipped chaos demo into exact same directory - right?

full flare May 15, 2020, 7:11 PM

#

yes

naive fossil May 15, 2020, 7:11 PM

#

oh, and now try point 4 and it's fail?

#

but

#

point 3 says that you should run Setup before placing

chaos demo into engine directory

full flare May 15, 2020, 7:12 PM

#

which I did

naive fossil May 15, 2020, 7:12 PM

#

ok

#

for me it's look like you don't have some dependency at VS installer or sth?

full flare May 15, 2020, 7:14 PM

#

is that in my vs2017 or in the github version I downloaded?

#

from what you saw I picked the correct branch to download from correct?

naive fossil May 15, 2020, 7:16 PM

#

I think you picked the right one

#

and I mean run your VS installer

full flare May 15, 2020, 7:20 PM

#

and I can't find the UE4.sln file they're talking about

naive fossil May 15, 2020, 7:20 PM

you can't cause you didint generate project files

#

check in VS Intaller C++ features for gamedev and

#

Hi there! When I build UE4 from source code, it builds properly and I can launch the editor. However, I can't debug.

In the project settings (of all projects in the solution as far as I can see), the debug settings are empty. And if I try to start with local debugger, I get an error telling me that it is unable to start debugging.

Did anyone have this issue, any right way to sort it out?
I have installs of VS2015/2017/2019 and am using 2017 for UE as recommended. I have installed the "Game Development in C++" with VS too.

#

Development Editor / Win64 / UE4

#

(but all configurations have empty Debug settings)

prime torrent May 18, 2020, 12:14 PM

#

You'll need to switch to Debug Editor if you want to debug into the Editor

torn vigil May 18, 2020, 12:23 PM

#

I can try rebuilding for that configuration but the Git Readme is out of date then as it says to set the Development Editor config and press F5

#

I'll try though and I'll let you know if it helped! Thanks

prime torrent May 18, 2020, 12:24 PM

Development Editor is meant to be a speedy version to mostly provide some debugging for your project verses trying to debug the entire Editor which is going to be slow

Some thtorials i saw say i should build the whole solutions other the ue4 target

Which one should i use?

torn vigil May 18, 2020, 1:50 PM

Does anyone have an idea why?

torn vigil May 18, 2020, 2:38 PM

@prime torrent I want to debug the engine itself, not any specific project. I should be able to, especially since the docs say just to "Press F5", but it doesn't work in my case, surely it's just missing something.

prime torrent May 18, 2020, 2:38 PM

#

I'd just make an empty project

torn vigil May 18, 2020, 2:38 PM

#

But to make the project, don't I have to launch UE? XD

prime torrent May 18, 2020, 2:38 PM

#

And that should let you debug whatever you want.

torn vigil May 18, 2020, 2:39 PM

#

So I should launch UE without debugger, to create a project, to then be able to launch it with a debugger?

prime torrent May 18, 2020, 2:39 PM

#

You can't launch UE?

torn vigil May 18, 2020, 2:39 PM

#

I feel like if I have to do that it means there is an underlying issue in my setup, and that I may have problems along the line

Funny enough actually, even if I use Ctrl + F5 (start without debugger), it says "Unable to start debugging, check the project properties.."

Well.... at least I can't help you with a gif as basis. Not even sure, if I can help you with the logs, since I don't use chaos, but from my point of view your chances of someone helping you is way higher if you provide sufficient information. The rest is up to you

stable hemlock May 18, 2020, 3:04 PM

#

Well there is no more information to provide as far as im aware. Theese are the only errors

silver hollow May 18, 2020, 4:24 PM

#

Then learn to debug compiler errors...
Or don't compile new, not production-ready physics engine if you're not ready to handle all the issues. Compiling it's just a first step, probably a lot of things simply don't work yet in Chaos.

#

Did you follow information posted on the official forums how to compile Chaos? I'm asking because I've seen posts people who simply followed it and it worked. Maybe you did something differently.

stable hemlock May 18, 2020, 4:32 PM

#

I followed it line by line

#

I'm recompiling now to see if it makes any difference after adding bUseChaos = true as well

silver hollow May 18, 2020, 4:34 PM

#

it should make a difference, than Chaos namespace is used instead of PhysX IIRC (but I did compile it just once a months ago, not 100% sure)

stable hemlock May 18, 2020, 4:35 PM

#

Also i keep getting mixed inputs. Some sources say build the whole solution others say just build the UE4 target

#

I compiled nvidia's branches before by only compiling the UE4 target so im not sure if compiling the whole solution is necessary.

@stable hemlock Thanks for the assist I'll keep you posted.

ok

full flare May 21, 2020, 5:01 PM

@stable hemlock It still wants me to rebuild the project in something other than UE4... With it no running...

#

So I'm trying that... I hope Im doing this right....

stable hemlock May 21, 2020, 5:02 PM

#

@full flare Yes i know, i imagine you built the engine right?

full flare May 21, 2020, 5:02 PM

#

yes

stable hemlock May 21, 2020, 5:03 PM

#

start it from the win64 folder

#

its called ue4editor.exe

#

Then open the destruction demo project from the engine menu

#

it'll ask you to open in visual studio

#

do so and then a target file called destructiondemo will appear under the UE4 target

#

right click that and build

full flare May 21, 2020, 5:05 PM

#

it auto ran from VS2017... I'm trying to build the Chaosdestructiondemo now.... I tried that it didn't load it.. it tried to build in ue4... That's why I'm building now but outside of UE4 will that still work?

full flare May 22, 2020, 12:01 AM

#

@stable hemlock What's the issue?

stable hemlock May 22, 2020, 12:24 AM

#

@full flare I need to change the code of skeletal mesh to support more than 255 materials.
I found the code for Static Mesh but it is not the same as skeletal mesh.

#

@full flare I just need to find it, I'm desperate ):

full flare May 22, 2020, 12:26 AM

#

@stable hemlock There I can not help you... Sorry... Why would you need more than 255 materials and is this Materials like masters or instances?

stable hemlock May 22, 2020, 12:28 AM

#

@full flare Because my model has 300 material slots.

full flare May 22, 2020, 12:39 AM

#

100% different materials? or could some of them be instanced?

stable hemlock May 22, 2020, 12:40 AM

#

@full flare Different materials

full flare May 22, 2020, 12:42 AM

#

@stable hemlock That's a hard one... Sorry but I'm not the right one to ask....

stable hemlock May 22, 2020, 12:42 AM

#

@full flare Thank you.

full flare May 22, 2020, 12:42 AM

#

np

#

@stable hemlock Is there any way for you to combine materials as instances to save on slots? that may be easier...

stable hemlock May 22, 2020, 12:45 AM

#

@full flare Mmm, I don't know.

full flare May 22, 2020, 12:47 AM

#

@stable hemlock Like metals, glass etc... etc...

stable hemlock May 22, 2020, 12:50 AM

#

@full flare I see, but I think it would take longer, since I have many models like that.

full flare May 22, 2020, 12:51 AM

#

@stable hemlock you'll have to keep asking around, tried google?

stable hemlock May 22, 2020, 12:52 AM

#

@full flare Yes xD

full flare May 22, 2020, 12:59 AM

#

@stable hemlock You said you found a bit a code that changes it for Static Meshes... Do you know where the bit of code in UE4's code that limits you to 255 is?

#

@stable hemlock If so you could possibly change it there and rebuild the engine...

stable hemlock May 22, 2020, 1:01 AM

#

@full flare It's this

📎 UE4_-_Microsoft_Visual_Studio_5_19_2020_11_07_48_PM.png

#

It's on Static Mesh.cpp

#

I searched Skeletal mesh.cpp but it is not there.

#

@full flare I was thinking about doing that.

full flare May 22, 2020, 1:02 AM

#

So I would think that the Material Index is what controls that but I'm not sure...

#

@stable hemlock I think that controls the allowed amount... so maybe look there...

stable hemlock May 22, 2020, 1:07 AM

#

@full flare I've already searched almost the entire engine, I just need to look at source

#

@full flare If you change this it is limited as if it was the Skeleton Mesh.

📎 UE4_-_Microsoft_Visual_Studio_5_21_2020_8_09_57_PM_LI.jpg

full flare May 22, 2020, 1:21 AM

#

@stable hemlock so it would need to be 12C or 012C if hex to number is correct for 300 instead of 255

#

@stable hemlock I'd be willing to bet that is not the only place you'll need to make that change too...

stable hemlock May 22, 2020, 1:24 AM

#

@full flare Can you help me? Or do you know how to search for code in Visual Studio?

full flare May 22, 2020, 1:24 AM

#

@stable hemlock and just for fun Binary of 100101100... (sorry just a bit of fun there)

#

I know how to search for code Yes.... but yours is very specific and UE4 was put together with a lot of checks and balances as it were... so there should be more than one place. and if you change in one place you need to change in all or stuff goes wrong quick... and UE4 will crash on you... I'm just rebuilding so I can play with the ChaosDestructionDemo... and I'm having issues with that little change...

#

@stable hemlock So in that regard I feel your pain and frustration...

stable hemlock May 22, 2020, 1:31 AM

#

@full flare Could you give me a hint? At least I'm not the only haha

full flare May 22, 2020, 1:41 AM

#

@stable hemlock Well best as I can tell you can try to remove the limit all together and see what happens. No limit, nothing to exceed... or look for other lines references the same things and see what they're connected to...

stable hemlock May 22, 2020, 1:44 AM

#

@full flare Last question: How do I remove the limit from everyone?

full flare May 22, 2020, 1:46 AM

#

@stable hemlock I would assume and again this a guess but take away from references that there is even a limit to exceed or look for... anything other then that is trial and error... unless else actuals knows the answer to your question...

#

@stable hemlock Sorry I couldn't be more help to you... I've got to call it a night... gotta put the kids to bed. Take it easy.

Is there any good resources for the cook process and tips or tricks for that? I'd like to get to know more about that cause it's a very big chunk of time currently...

silver hollow May 28, 2020, 8:35 AM

#

@heady gate the best trick is to invest into dedicated machine (optionally with beefy CPU and loads of RAM). Set up cooking project daily (automatic script triggered by Jenkins/TeamCity) so you have a new cook waiting for you. And cooking process is verified all the time. (your machine could be used also if running cooking while you don't use it)

For tests on your machine sometimes you can use iterative cooks (rebuilding only changes) or even cook on the fly.

hi there, working with 4.16.3 but Timespan import function is not implemented, i can see that its working on 4.18, 4.21 .... tried to download source of 4.16 and 4.18, make the timespan changes there from 4.18 but no luck... still not working, no timespan errors during compile, maybe somebody got import function for timespan and 4.16 ? 🙂 i know its old engine but i will have to completely fix my project to have it on newer UE4 engine and i dont really want to do that now

versed rapids Jun 1, 2020, 6:44 PM

this kind of changes usually involves lot of modifications throughout the engine, pretty hard to find sometimes unless you have the time to read all the sources file by file

#

I'd rather try to upgrade my project for every release unless I'm quite ready to release the game

Memset sets a range of bytes to the same value

thus, the value you give it is a uint8

why are you even changing that code?

quaint adder Jun 2, 2020, 5:12 PM

#

Is it the case that if you edit any engine file, UBT will trigger a full rebuild? There should be a way to mark the whole damn dir as read only without having to rely on p4...

silver hollow Jun 2, 2020, 5:22 PM

#

what? recompiled are only things that depends on changed file
it doesn't equal to "full rebuild" on editing "any engine file"

quaint adder Jun 2, 2020, 5:22 PM

#

Hm I must have screwed up

#

I also changed targets to devgame complied but then stopped it

silver hollow Jun 2, 2020, 5:23 PM

#

all files are actually marked as read-only at the moment of adding it to P4, but VS plugin automatically checks out edited files - that's what we usually choose 😉

quaint adder Jun 2, 2020, 5:23 PM

#

Yeah I must have messed up when I stopped it and then switched back deveditor

silver hollow Jun 2, 2020, 5:24 PM

quaint adder Jun 2, 2020, 5:24 PM

#

I reconcile offline work when I use P4

#

But I haven't set it up for 4.25 yet

silver hollow Jun 2, 2020, 5:24 PM

#

although if you would change something in core, it would rebuild half of the engine anyway, like imagine how many classes uses AActor in some way 😄

quaint adder Jun 2, 2020, 5:25 PM

#

Yeah I accidentally added spaces to one file bc I was looking up a class definition for Imodule

silver hollow Jun 2, 2020, 5:25 PM

#

as long as you don't save a file on accidental edit (like holding W like playing and exception catches you), you should be fine

#

if modification time of file isn't newer than last build 😉

quaint adder Jun 2, 2020, 5:27 PM

#

Yeah I undid the change but I think by that time it was too late. Well hope6 this doesn't take long...

P4 saved me so many times from accidentally doing this... Ugh

@elder falcon how long was "while ago"? 😉

#

I'm curious, how much it improved while announced ready for Fortnite and I see a lot of Chaos work submitted daily

stable hemlock Jun 4, 2020, 8:33 AM

#

fortnite doesn't have a lot of simulation bodies, most of it is just queries

#

makes sense for simulation performance not being a priority right now

#

to be honest, I wouldn't be surprised if they released chaos with ue5

#

not because of the development speed, but because it makes marketing sense, and it'll be a nice chance to do some breaking changes

silver hollow Jun 4, 2020, 10:36 AM

#

nah, they have enough for UE5 (and they could work on more, i.e. custom scripting language)

#

and on the best thing about UE4 is gradual rework of the engine, upgrading to Chaos alone would be enough for UE 4.2x

#

doesn't seem to be a huge breaking change if they have equivalent of PhysX functionality, even working on Chaos Vehicles now

#

obviously destruction would be done/designed from scratch, but that expected when switching from useless Apex to proper destruction system 😉

#

upgrade to UE5 with renderer, physics (and perhaps more) could actually make many studios to wait with upgrade for next project, so it would be more like UE3-UE4 transition and I bet Epic wishes to avoid that

brisk silo Jun 4, 2020, 11:04 AM

#

Has anyone managed to build Development in with TargetLinkType.Modular?

#

Mine keeps failing because the engine's Development configuration outputs binaries named UE4Editor-Whatever.lib and my project expects UE4-Whatever.lib.

#

But all the UE4[Blank] binaries are exclusively available as a single, monolithic binary.

#

Therefore TargetLinkType.Modular cannot work.

#

If I'm missing something, I'd appreciate any advice.

turbid sigil Jun 4, 2020, 10:52 PM

#

you guys realize there probably is not going to be another release before ue5 right?

#

one of the people on the UE4.25 live stream say there was not going to be another release before people would be shipping for next-gen consoles

#

and that's holiday 2020

#

so why release a new version right before UE5 preview?

stable hemlock Jun 4, 2020, 11:07 PM

#

well they did update the version file

#

master branch is at 4.26

#

plus ue4 probably will get bug fixes for a while, at least for the sake of licensees

#

4.25-plus branch is specifically for the people who are shipping with the next gen consoles

turbid sigil Jun 4, 2020, 11:32 PM

#

idk that's just what they said

#

also I assume UE5 license will be same as UE4

silver hollow Jun 5, 2020, 7:43 AM

#

they developed a new physics engine, renderer and shitload of stuff along to mainline UE4 for years
it's their modus operandi, not to branch engine for year which would freeze releasing code for most of features and updates not related to major physics/renderer/else upgrade 😉

#

we should have 4.26, not sure if another update this year...
but "preview of UE5 early in 2021 and release later in year" really sounds like "release in 2022", we could still have one or two UE4 next year 😛

#

one of the people on the UE4.25 live stream say there was not going to be another release before people would be shipping for next-gen consoles
@turbid sigil even in 4.26 would come in August/September, it would be too risky to upgrade engine for big game with fragments of modified engine, although game already implemented/tested/fixed and prepared for certification
especially if they would switch to Chaos in 4.26 😉

turbid sigil Jun 5, 2020, 1:00 PM

#

@silver hollow well that's just what they said on the UE4.25 live stream. Also they wouldn't remove physx right when they switch to it. They better fix the performance before they do :P.

stable hemlock Jun 5, 2020, 4:01 PM

#

there is 5 months until next gen console launch, and close to a year for ue5 beta

#

6-7 at least months between next gen release and ue5 beta

#

I wouldn't be surprised to see another ue4 release between now and then

#

of course, there could be new ue4 versions after ue5 release too

#

its not like its unprecedented, there used to be ue2.5

opal gorge Jun 5, 2020, 6:36 PM

The enigne now won't launch for me... it just kinda spins indefinitely when trying to load srvcli.dll?

ue 4.26 this year will be the last probabaly

#

UE5 is still >incremental< update

#

seems like people forget that

#

yes it's bigger and major version update allows for more leeway in remove old junk

#

how much it will affect you depends on which parts of engine you used

i do not modify sources

#

Question: I cannot find when playing a game (for simplicity, whatever mode (PIE, Standalone etc)) and a crash occurs, where the handoff happens from the 'game' to eventually report the crash through the CrashReportClient. Where does it actually start?

#

I feel like its something very close to HAL/ExceptionHandling, I thought I'd find something in HAL/ThreadHeartBeat and that also seems very close, as if this is used to detect if the application is still reporting. For example, if not overriding the functionality of the pointer symbol (say to handle a null pointer exception instead of just crash), then C++ programs will crash from no handling. However, if you call a method using a null pointer in Unreal, it will crash and eventually call the crashreportclient, but from the moment that bogus method is called, what is it that eventually leads to the crashreportclient being called? What begins this process so I may track down what I need?

hidden hedge Jun 8, 2020, 7:10 PM

#

            bCrashReporterRan = FPlatformProcess::CreateProc(*CrashClientPath, *CrashReportClientArguments, true, false, false, NULL, 0, NULL, NULL).IsValid();```

#

probably here in WindowsPlatformCrashContext.cpp

gritty basin Jun 8, 2020, 7:14 PM

#

Hey sswires, that is one of the translation units I am reviewing, but what would call that? I am looking for what in the engine is actually saying 'this is a failure'; the first thing recognizing and handling the failure to eventually get to the crash reporter. I need this so I can see how what you posted is called because I need to start doing this for mobile devices. By default, mobile devices are not included in the crashreportclient's list of OS's that are supported (for obvious reasons)

#

Perhaps Unreal internally uses assertion macros (assertionmacros) for the engine itself, as well as user explicit usage of these macros. For example, perhaps using a null pointer is handled using one of these macros by default so Unreal can gracefully exit with a minidump, stacktrace, and report of the error.

#

Here is a comment at the top of RuntimeErrors.h: // By default we bubble up runtime errors to the editor or log under the same circumstances as we assert with check/ensure

gritty basin Jun 8, 2020, 7:53 PM

#

UGH, I'm so freaking close: its definitely right next to ExceptionHandling in HAL

In addition, there are these errors related to rc.exe which I just don't have the background knowledge to understand.

halcyon fable Jun 9, 2020, 1:35 PM

#

So packaging is a very controverted topic as most people, even those who think they understand it, only ever copy a command or 2 from Google and call it a day. In 99% of the cases, those commands perform redundant steps as they are, in fact, a chain of commands. For example, I am able to run isolated build commands, only for the configurations that interest me. I can also run isolated cook operations only for the configurations that interest me as well. However, I cannot run isolated staging/packaging command because of this:

#

Assuming I have already built and cooked my project, why can I not perform an independent staging/packaging project?

#

[Removed Mention] Sorry to tag. I rarely chat here and never tag Epic employees, but I've been struggling for ages to find an answer to this and there doesn't seem to be one anywhere on the internet or at any of the people I know. Over the years I've watched a huge chunk of your content and I don't know who else to ask.

#

Any help is much appreciated!

#

I'd also like to mention running these commands independently is very important for a clean CI/CD pipeline - in general, not just for me.

halcyon fable Jun 9, 2020, 1:43 PM

#

I really didn't/don't know who else to ask. Now that you mentioned seeing a PR specifically for this, I guess there truly is no alternative than to change it myself, even though I really really hate the idea of having to modify the engine.

#

The entire build system has always been convoluted, but such restrictions shouldn't have existed in the first place.

#

The whole modular architecture of module/target/uplugin files is massively tainted right by these last few steps.

#

And I've proposed that the Marketplace included programs and "non-project" products several times specifically because I'd like to rework parts such as these as different tools myself, as other have also done on the forums with other areas.

#

@elder falcon Your tip sent me on the right path and helped me find the solution: https://github.com/EpicGames/UnrealEngine/pull/6812

#

The final command looks like this:

#

AutomationTool.exe BuildCookRun -Project="D:/Professional/Projects/DevOpsTests/DevOpsTests.uproject" -Target=DevOpsTestsClient -Platform=Win64 -SkipCook -Stage -StagingDirectory="C:\Users\Vlad\Desktop"

#

The problem was there was no indication of -Client being needed, therefore -Stage, even with -SkipCook fails as well.

fresh coral Jun 9, 2020, 10:15 PM

@gritty basin As you might imagine crash handling is very platform dependent and relies heavily on OS functionality, so the actual work takes place in the various PlatformCrashContext implementations. I'm not sure if it's possible to do much in the way of crash handling on mobile platforms.

hi @fresh coral yes, i appreciate you reaching out to me, I do understand this. We have a source version of UE with a few games source controlled all in perforce. It appears even on windows the crashreportclient isn't running. The log for a game shows this upon a [forced] crash:

Is there any other steps I need to do besides Rebuild Solution to prevent this error occuring?

You don't have them set as read-only do you (e.g. perforce?)

wise cape Jun 11, 2020, 8:12 AM

#

Likely read only, if you're not using source control on it - right click intermediate and set in properties read only off. If you are using source control, make sure your intermediate folders are included in your p4ignore file.

I'll double check that, I use git, but I just did a fresh clone and those folders are built by Setup.bat which rules out read-only (theoretically). Just building them again now.

#

I'm rebuilding anyway as I did a VS Update and got implicit conversion errors. Similar to the ADODB one, but related to LiveConsoleCoding instead

UE4.25.1 builds with VS2019 (16.6.2) however 4.24.3 fails with the following, already patched the ADODB issue, and this is a secondary error on this version (16.5 was working though). Any idea's where in LivingCodingConsole this could be?

tardy pollen Jun 11, 2020, 12:27 PM

#

the editor is crashing

#

everytime i do a map check or build lighting

#

sometimes its a failed assertion other times its a function not found

#

the common thing is that ntdll.dll crashing it apparently

#

any clues to that ?

#

it only happens on a specific project...

round pagoda Jun 11, 2020, 12:51 PM

Sounds like a problem with the project... Try looking at the callstack trace to see what function is causing it

MapCheck

#

that's it

there is nothing related to my project

Open a different level in the project, any issues?

tardy pollen Jun 11, 2020, 12:54 PM

that's the thing, i only have one level

round pagoda Jun 11, 2020, 12:54 PM

Map check looks at every asset in the level, so that can very much be project-related

#

Ok... So go and make a new level and put some basic engine assets in

tardy pollen Jun 11, 2020, 12:55 PM

#

sure sure, after i finish moving the engine from my ssd

#

need to setup engine from source

#

to work with extra features and debug issues properly

stable hemlock Jun 12, 2020, 12:45 AM

#

@tardy pollen In case you didn't solve your problem yet, you just need to add a nullptr Comparison on those variables

#

for example, (!debugger) should become (debugger == nullptr)

#

They are about 10-15 changes All in all

#

    UPROPERTY(EditAnywhere, config, Category = Editor, meta = (
        ConsoleVariable = "cook.AllowCookedDataInEditorBuilds", DisplayName = "Allow Cooked Content In The Editor",
        ToolTip = "If true, the editor will be able to open cooked assets (limited to a subset of supported asset types).",
        ConfigRestartRequired = true))
    uint32 bAllowCookedDataInEditorBuilds : 1;```

#

anyone knows the full extent of supported asset types ?

tardy pollen Jun 12, 2020, 7:27 AM

#

thank you

#

to be honest i haven't fixed my issue

building UE from source takes time

tardy pollen Jun 12, 2020, 11:43 AM

#

hey there

#

I finally "found" the issue causing map check to fail

#

but its not really descriptive, any clue about this brush thing ?

#

📎 unknown.png

#

my map is made up from static meshes, no terrain at all

#

i created a new type of error

#

but i don't know if it's gonna work or not

#

well it should work, but i mean idk how to make this a "thing" that I can create a PR for

#

indeed i have found and fixed the issue

#

📎 unknown.png

#

it seems that having a blocking volume with no polygons causes the map check to crash the Editor

#

since Brush->Polys are used directly without checking if it's a nullptr

stable hemlock Jun 12, 2020, 12:17 PM

#

@tardy pollen By any chance are you trying to import some cooked content?

tardy pollen Jun 12, 2020, 12:18 PM

#

no no

stable hemlock Jun 12, 2020, 12:18 PM

#

If you are using your custom engine version downloaded from github, you can simply add an extra line/s to initialize it

tardy pollen Jun 12, 2020, 12:18 PM

#

it's just a bad blocking volume in my map

#

but the editor needs to check if its a nullptr before using variables directly

#

I fixed it by simply adding said check

#

I also added an error type telling you that the brush's polygon is a nullptr

#

now i'm looking into creating a pull request for this fix

stable hemlock Jun 12, 2020, 12:21 PM

#

I've seen that type of error when I was playing with cooked content for cooked volumes, such as light importance volume, etc. That's why I was wondering 😄

tardy pollen Jun 12, 2020, 12:22 PM

#

oh,

#

then i just made a fix

tardy pollen Jun 12, 2020, 1:42 PM

#

i'm hoping this is something about me not fully mastering git

#

I use it on all my projects, but they're always solo projects with no contributions

#

basically i use it for tracking and keeping a clean copy of the projects (commits and branches)

#

imagine that some developer in epic games

didn't check a variable's validity

@stable hemlock I found adding /wd4800 to the vctools file fixes it for now. I actually couldn’t find which variables were causing the problem, VS was constantly opening up comip.h, it’s already fixed in 4.25.1 though so it’s only an issue with 4.24.3. Might be worth switching up, my project is still in its infancy anyway. Thanks though, will probably fix that up tomorrow so then I have both engines working.

@gritty basin Did you ever get anywhere with your investigations into the Crash Reporter? Im trying to integrate a middleware solutions that uses the CR to send up builds and all, but our local code builds of the engine dont engage the CR. Just crash with a minimal popup.

gritty basin Jun 13, 2020, 10:05 PM

#

@celest viper for mobile or desktop?

celest viper Jun 13, 2020, 10:32 PM

#

just desktop. Source built editor. I know you were looking at mobile, I was just hoping youd picked something up along the way heh

gritty basin Jun 13, 2020, 10:32 PM

#

so make sure that you have CrashReporterClient.exe and not CrashReportClient-W64-Debug.exe or something like that first

#

should be in engine\binaries\win64 someting like that

celest viper Jun 13, 2020, 10:33 PM

#

aight one moment

#

yup got that

gritty basin Jun 13, 2020, 10:36 PM

#

does the cr even come up? what happens

#

what happens when it crashes, do you get a popup that says Fatal error?

celest viper Jun 13, 2020, 10:37 PM

#

Yes, just the popup for Fatal Error, not the full CR

gritty basin Jun 13, 2020, 10:37 PM

#

so in the engine code, that pops up when the CR fails to load

celest viper Jun 13, 2020, 10:38 PM

#

well that makes some sense. Is there a log I can look at for why it would fail to load?

gritty basin Jun 13, 2020, 10:38 PM

#

for me, it was failing because the engine was using a string literal "CrashReportClient.exe" appended to the current running directory of UE, which, there was no such thing, i just renamed the CR client to the right filename and it worked for me

#

look in your game folder

#

saved

celest viper Jun 13, 2020, 10:40 PM

#

Interesting. What are looking for under there? One of the crashes?

gritty basin Jun 13, 2020, 10:41 PM

#

there is a folder for crashes, and a log folder

#

you may get some info there

celest viper Jun 13, 2020, 10:42 PM

#

Where did you find that string literal you mentioned in the engine?

gritty basin Jun 13, 2020, 10:44 PM

#

in visual studio, just search for crashreportclient.exe. I think it was WindowsPlatformMisc, I honestly can't remember

#

i am not in a position to check, but if you search VS, make sure you use ctl-shift-f

celest viper Jun 13, 2020, 10:44 PM

#

yeah I started that up after I asked

#

ok

gritty basin Jun 13, 2020, 10:45 PM

#

if you're getting Fatal error (you can search that too) that is a direct result of the CR not runnning

#

there is a check for that, and if it doesn't load, that will pop up

celest viper Jun 13, 2020, 10:46 PM

#

cool cool dude Ill dig around wiht this for a minute

#

thanks for the assist

gritty basin Jun 13, 2020, 10:46 PM

#

o wait

#

@celest viper is this a packaged product, or just running in the editor?

celest viper Jun 13, 2020, 10:58 PM

#

hah in the long run itll be packaged, but for now just the editor

#

I see therees a different exe that Im assuming is for editor

#

CRClientEditor.exe

gritty basin Jun 13, 2020, 10:58 PM

#

no, CrashReportClient.exe

celest viper Jun 13, 2020, 11:00 PM

#

#if WITH_EDITOR
    const TCHAR CrashReportClientShippingName[] = TEXT("CrashReportClientEditor.exe");
    const TCHAR CrashReportClientDevelopmentName[] = TEXT("CrashReportClientEditor-Win64-Development.exe");
#else
    const TCHAR CrashReportClientShippingName[] = TEXT("CrashReportClient.exe");
    const TCHAR CrashReportClientDevelopmentName[] = TEXT("CrashReportClient-Win64-Development.exe");
#endif```  Thats what I was just reading, I am making assumptions on that Editor version though

gritty basin Jun 13, 2020, 11:02 PM

#

what version do you have? the version I was referring to was 4.23

celest viper Jun 13, 2020, 11:02 PM

#

interesting

#

Thats in 4.24.2

gritty basin Jun 13, 2020, 11:02 PM

#

i know they changed around how the crashreportclient is evaluated from 4.23 on

#

someone showed me code in 4.25 that showed a completely different way the path is enumerated

celest viper Jun 13, 2020, 11:04 PM

#

and yeah that change came in when I integrated 4.24 last year

#

er earlier this year

#

fuck 2020

gritty basin Jun 13, 2020, 11:04 PM

#

find "Fatal error"

#

and go back from there

celest viper Jun 13, 2020, 11:08 PM

#

ok well I got the reporter to launch at least!

#

Ultimately we have a build script that was building the CRClient but only as a Shipping target. Changing it to 1) use the correct target of the build and 2) to also build the CrashReportClientEditor moved things forward

#

Again this looks like a change to the whole system in the last couple of engine revisions

gritty basin Jun 13, 2020, 11:10 PM

#

it is a significant change, yes

#

and the fact that Epic doesn't really support the crash reporter beyond desktop makes me wonder why the move

celest viper Jun 13, 2020, 11:12 PM

#

eh I imagine its at hte level of "We have 1000 programmers working on this thing trying to improve it all the time, somebody should spend time keeping the CrashReporter moving forward"

#

who knows maybe in mythical UE5 itll have crash support for mobile heh

gritty basin Jun 13, 2020, 11:14 PM

#

doubt that, if it was easy to do, they would've had a solution already. The fact that mobile OS's are very different in nature from desktop OS's and are far more stricter, with apple completely micromanaging their OS, it seems like the way certain SDK's do it is using some kind of monitor for probing folder(s) for files, and deleting them when the file is sent. That is pure guess.

#

As I understand it, iOS does not allow spawning of subprocesses, but that is through questionable reading

#

I am not knowledgeable on mobile OS's

celest viper Jun 13, 2020, 11:15 PM

#

yeah me either.

#

oh one other thought. Is there a seperate space for logs generated by the crash reporter?

gritty basin Jun 13, 2020, 11:16 PM

#

not that i am aware of

#

there is a crash log

#

but one specifically for the CR? not that i know of that comes out of the box

celest viper Jun 13, 2020, 11:16 PM

#

Yeah ok

#

The end result is Im redirecting where this crash is getting uploaded to and now that I have the CR working again I can properly debug that aspect of it

gritty basin Jun 13, 2020, 11:17 PM

#

🙂 wooooot

celest viper Jun 13, 2020, 11:17 PM

iOS won't let you have access to lot's of features, I've heard it's really easy to get on apples bad side if you use unapproved features, that's why to this day, microsofts "your phone" app only works for android when it comes to letting you reply to texts and phone calls from your pc

#

I'm here asking what is todays benefit of building UE from source? I understand if you wanted to do something advanced, like adding FName tags if UE's rigidbody system, for something along the lines of making a hit system that registers other body parts, then you would want access to UE source code, but what features aren't in the launcher build? I know chaos is in the newer versions

gritty basin Jun 13, 2020, 11:25 PM

#

customization of the engine, as small or large as you want is the benefit.

#

basically total control

#

and you can pull directly from the github source and implement updates into your source

Xcode 14 is busted. Downgrading to 13.1 fixed it, but it took forever to figure that out. Just got it today.
@opaque lotus Xcode 11.4 you mean ?

I'd need to double check when I'm at my PC next, but I thought 13.1

@opaque lotus i am using Xcode 11.1 and the new version out in the appstore right now iss 11.5 so i assume you are talking about 11.3

FCoreUObjectDelegates::OnObjectPropertyChanged might do the tricky @willow spindle

thanks

#

@spiral mortar excellent that worked

#

did this in an editor StartupModule (for reference if anyone else needs it):

void FGameManagementFrameworkEditorModule::StartupModule()
{
    FCoreUObjectDelegates::OnObjectPropertyChanged.AddLambda([](UObject *Obj, struct FPropertyChangedEvent &Event) {
        auto Config = Cast<UGameManagementFrameworkConfig>(Obj);
        if (Config != nullptr)
        {
            // Refresh the blueprint action list whenever we update our game managers.
            FBlueprintActionDatabase::Get().RefreshAll();
        }
    });

The staging phase of the packaging process naturally creates a Intermediate\Staging\[ProjectName][ProjectConfiguration].exe file. In the final output of the whole packaging process, this .exe does indeed exist as expected on my end, but running the exact same command on a different machine, through a GitLab runner, somehow doesn't create it. This leads to the final build requiring to be started as:

#

WindowsClient\Engine\UE4Client-Shipping.exe WindowsClient\[ProjectName]\[ProjectName].uproject

#

Has anyone encountered this before?

Sorry to bother i was trying to build ue4 (UWP) from source. I did the setup.bat and the GenerateProjectFiles.bat everything in order i opened the ue4.sln and started building ue4 and success with 9 errors and 0 warnings afterwards i selected ue4 and select as startup project and then it took a turn for the worse

I'm being hit with the "Fatal error" crash on 4.25. There's discussion in this channel, but I can't seem to figure out a fix. Can anyone lend a word of advice?

I've already redownloaded the whole engine, rebuilt, but when I tried to open my project it corrupted the engine install or something. Each time I run the engine (as well as the project), I see:

@gritty basin, if you don't mind me tagging you. You were speaking about this issue in previous versions of the editor. Do you have any idea how to resolve this issue in 4.25?

The log would be much more helpful 😄

marble rune Jun 15, 2020, 12:10 AM

#

@stable hemlock Just an FYI, I went through 4.24.3 and fixed up the 10-15 issues by adding either == nullptr or != nullptr checks as suggested (and found the lines in the output, albeit the error list kept sending me to comip.h. 4 times trying to compile on the latest 16.6.2 patch for VS 2019 I ended up with BSOD's regarding WHEA Uncorrectable Errors (normally related to hardware) every time about 25% into the compile.

#

Added /wd4800 fix the to vctools file instead and compiles fine without an issue

#

Very odd, according to MS Visual Studio should never cause that type of blue screen death. But that was too consistent. Quite concerning that a compilation in VS2019 could result in a blue screen though. I may have had some != and == mixed up, but I would've expected those to cause issues at runtime, not compilation time. Just glad 4.25.1 doesn't require these fixes.... albeit seeing the number of reports that 4.25.1 is not stable. Might hold off that upgrade for a bit longer.

celest viper Jun 15, 2020, 1:00 AM

@quartz pier yeah Logs would help. Also if youre building the engine out of an IDE you can launch it from there and that might give you more info on the crash

After the fatal error pops up, even the editor binary (NOT the project) will error each time you start it. I have to delete the intermediate folder for it to launch again. It then gets to the project selection screen and freezes, hovering around 9% cpu and eventually giving you a fatal error.

I can delete the binaries folder of the project and recompile, then it loads for a bit, even boots the editor, but during shader compile it crashes. In both cases, it seems to get stuck during the shader recompile.

quartz pier Jun 15, 2020, 9:27 AM

I have recompiled the whole editor from scratch, I have brought back a revision of the project that I know worked through source control, and it still does this. At my wit's end...this defies all logic.

gritty basin Jun 15, 2020, 12:57 PM

#

@quartz pier It's not so much about fixing it. In 4.23, the crash reporter fails to load and prints this message. For me it was because the engine uses a literal string "CrashReportClient.exe" and appends to the current running directory of the engine executable. However, there was no such file. Instead there was "crashreportclient-win64-debug.exe". Using source, this is probably from the engine build using debug-game-editor. After renaming the file to CrashReportClient, it worked as it should in Windows.

quartz pier Jun 15, 2020, 12:59 PM

#

It seems like in my case the fatal error window was caused by not having compiled the crash reporter @gritty basin

#

I fixed that actually

#

I still can't boot the engine though

#

Does anyone know if there's an equivalent to AppData\Local\UnrealEngine for the source build?

#

Strangely, I can start the UE4 editor through VisualStudio's debugger but it crashes when I open a project (because that reloads the binary WITHOUT visual studio's debugger, exits the process). I can also start my game's solution through visual studio's debugger and it loads fine.

#

But I can't open the UE4Editor binary directly

#

It exits with this exception_stack_overlow

I hope you fix that. I cannot help you with that particular issue.

Can anyone answer a couple of questions about UGS? I need to switch to source code so I can build Dedicated server, but we have no intention of modifying the source. If I setup UGS to distribute to my artists, can I also use UGS to distribute engine binaries to programmers? I.e. so they don't have to compile the Engine, just build the game dll?

gritty basin Jun 15, 2020, 2:48 PM

Question: 4.25 release notes: can anyone explain, in some detail, what this change is? "When the engine detects that an abnormal shutdown has occurred, we now spoof a crash report and send it from the CrashReportClientApp. "Abnormal shutdown" defined as: the shutdown did not appear to use a known exit path."

@gritty basin Better check commits inside related module of the engine in Github

gritty basin Jun 15, 2020, 2:56 PM

#

I have never gone to the UE github page; we do use source at work but I am not familiar with it. Probably should go do that 🙂 Thanks @lilac isle

lilac isle Jun 15, 2020, 3:00 PM

#

It should be inside Engine/Source/Programs/CrashReportClient path

calm mason Jun 15, 2020, 3:33 PM

#

I have downloaded from source and my root folder has Engine and MyGame folders in it. When I run GenerateProjectFiles.bat it creates UE4.sln but it does not contain MyGame project in there. Any ideas?

#

Project file is here: MyGame/MyGame.uproject

#

If I right click MyGame.uproject and choose "Generate project files" it produces MyGame.sln which has MyGame module and the (source) UE4 engine projects in it.

Has anyone built Unreal Game Sync? I'm unable to open the Solution because I need to install WIX 3.8 ?

celest viper Jun 16, 2020, 1:37 PM

#

@calm mason Yeah. I have but that was fairly easy to pull down in VS

calm mason Jun 16, 2020, 1:40 PM

#

I grabbed latest WIX but the project doesn't build with it, can't understand how to grab 3.8 specifically

#

I have another question regarding UGS, looks like it supports multiple Precompiled 'Archives' per project. As the engine code will very rarely change it makes sense to me to have one archive for the Engine and another for the Game dlls which will change a lot.
Is anyone using UGS like this?

lilac isle Jun 16, 2020, 1:46 PM

#

I think amount of people seriously using UGS is super limited at the moment 😄

calm mason Jun 16, 2020, 1:48 PM

#

Sure feels like it 😅

#

I guess the other option for me would be to make a pre-packaged style distribution

celest viper Jun 16, 2020, 2:07 PM

#

Id have to dig around on the Wix, I just remember digging thru the VS update options and found it, but that was forever ago

#

And no we dont use UGS split up like that, but thats an interesting thought. We just use the one big Archive of everything. It might be a bit more, but just seems safer in a way to keep everything in sync

calm mason Jun 16, 2020, 2:08 PM

#

yeah, kinda sucks to be downloading 500mb zip every time when it's only the game dlls that have changed

#

I'll report back if I get it working!

celest viper Jun 16, 2020, 2:11 PM

#

hah yeah, but then Im thinking of everything in an office environment, 500MB downloads are nothing!@

#

(until a Pandemic hits and now were all WFH anyways)

calm mason Jun 16, 2020, 3:39 PM

#

yeah that's right, our team is distributed and 500mb updates for every change is gonna suck for people on bad connections

#

if it has to be done like this then so be it

trying to split it into multiple archives is proving impossible so far

Ok I'm thinking this belongs here, the editor is able to click through invisible parts of object to select what is visible, I really need this behavior right now and I'm not sure how they are doing it. Anyone know where in source to start looking to see how they managed to do that?

calm mason Jun 17, 2020, 3:03 PM

I know it is possible to build a package version of the Editor from source.
If I set the right options during this step is it possible to build a Dedicated server game from this package version of UE4?
I know I can distribute the full source and build from that, but I need to avoid that if possible.

because you're editing a header that is included in many places and thus requires many files to be rebuilt

you should not edit baseengine.ini

put overrides in your project's defaultengine.ini instead
