Yeah okay, so you're obviously meant to somehow add that as a global definition when you build their branch then. But if they've forked the engine, it's kind of weird that they don't do so themselves.

low dust Feb 2, 2018, 5:58 PM

#

Build.cs itself contained those paths but it didn't let you use those outside the module itself (so had to add "FLEX-1.1.0/include/" to the include paths)

#

how they add it is here: https://github.com/0lento/UnrealEngine/blob/338f7c61a3f20f5467dd12d8d4aecdb75b0160ec/Engine/Source/ThirdParty/NVIDIA/TXAA/TXAA.Build.cs#L12

gloomy hamlet Feb 2, 2018, 6:00 PM

#

Right but that sets it only for that module. Since the define is checked from the renderer module too, it needs to be set globally in order for the full engine build to have everything compiled in correctly.

low dust Feb 2, 2018, 6:02 PM

#

but it hasn't been like that in past

#

so, they've changed that in 4.18?

#

or 4.17

gloomy hamlet Feb 2, 2018, 6:04 PM

#

Don't know, never looked at this code. Don't even know what it is 😉

#

Though having said that, yeah possible they just changed the build environment/definitions stuff in UBT and that's caused it. I did notice some increased strictness relating to setting definitions recently.

#

I gotta sleep. Good luck!

low dust Feb 2, 2018, 6:14 PM

#

thanks, but no luck needed, I'm not fixing this 😄

#

it compiles, even it's ugly

#

When building UE4 From the Source, is there anyway we can set a Default API?

grim halo Feb 2, 2018, 7:47 PM

#

in DepthRendering.cpp:1227, there's this line

#

bDirty |= DrawViewElements<FDepthDrawingPolicyFactory>(RHICmdList, View, DrawRenderState, Context, SDPG_World, true) || bDirty;

#

what is the point of the || bDirty at the end? isn't that implicit in the |= assignment at the beginning?

spiral mortar Feb 2, 2018, 7:54 PM

#

| != ||

grim halo Feb 2, 2018, 7:59 PM

#

not sure what | does to booleans

elder falcon Feb 2, 2018, 8:03 PM

#

the || bDirty is completely pointless, yes

#

maybe it was bDirty = ... at some point and changed to bDirty |= ... without removing the now obsolete part

grim halo Feb 2, 2018, 8:03 PM

#

it sounds like the same to me, unless the c++ implementation uses some whacky values to represent a true boolean

#

like, sometimes it just decides to use 2 instead of 1

elder falcon Feb 2, 2018, 8:06 PM

#

not sure how good the compiler is at optimizing this, it'll probably just remove the obsolete part

coarse aspen Feb 2, 2018, 8:41 PM

#

is build lighting bugged on current 4.19?

grim halo Feb 2, 2018, 9:27 PM

#

Bugged is a very broad word..

coarse aspen Feb 2, 2018, 9:35 PM

#

right, well it's telling me its out of memory and that it needs approximately 18 million gigabytes of it to build lighting for my map with 5 brushes on it and one default light source

gray glade Feb 2, 2018, 9:36 PM

#

That sounds like memory corruption.

#

99% of the time where you crash due to running out of memory while trying to allocate a gajillion bytes, it's because some garbage value was read.

#

It could be that a file/asset is corrupted or it could be something else happening in memory causing garbage values to be passed.

coarse aspen Feb 2, 2018, 9:38 PM

#

right, ill check into that

#

thanks

gray glade Feb 2, 2018, 9:38 PM

#

NP. Sorry it's not more specific, but it's some kind of lead to hunt down.

coarse aspen Feb 2, 2018, 9:38 PM

#

suspoect it could be one of these materials

#

yeah

gray glade Feb 2, 2018, 9:39 PM

#

If you're super comfortable with debugging the engine, you may be able to go up the callstack and figure out just what it tried to allocate.

#

And for what asset.

static spoke Feb 2, 2018, 11:19 PM

#

@gray glade Hello! I would like to ask you, is it possible for us to enable D3D12 for an example, as a Default API while building UE4 from the Source? So that we don't need the shortcut with -D3D12.

gray glade Feb 2, 2018, 11:20 PM

#

Not a clue.

coarse aspen Feb 2, 2018, 11:20 PM

#

heh this is interesting, its crashing the light compute on a new, completely empty map

#

only wants 52gb of memory now though

gray glade Feb 2, 2018, 11:21 PM

#

X|

coarse aspen Feb 2, 2018, 11:22 PM

#

maybe i downloaded after a really bad commit

stable hemlock Feb 3, 2018, 10:34 AM

#

If I have ue4 built from source up and running.... will the packaging process also take as long as the (re-)building of the engine in VS? I see similar console information and wonder if I also have to wait for 1-2 hours again

low dust Feb 3, 2018, 12:20 PM

#

for first run, yes

#

after it's built the things, future packaging process will be shorter

grim halo Feb 3, 2018, 6:44 PM

#

sorry if it's a stupid question, but I wonder when is shadow mapping done on the rendering pipeline

#

If I understand correctly, meshes are added to drawing policy factories, which in turn generate "drawing policies" for meshes, and then meshes are drawn one by one during the base pass following those policies

#

but in this system, when is shadow mapping done? isn't there supposed to be somewhere in the code where a depth buffer is drawn from the perspective of the lights?

elder falcon Feb 3, 2018, 7:01 PM

#

look at where FSceneRenderer::RenderShadowDepthMaps is called

grim halo Feb 3, 2018, 7:05 PM

#

thanks!

thick storm Feb 5, 2018, 9:39 AM

#

@stable hemlock if should't take anywhere close to building editor time

#

packaking runtime build only builds about 500 engine modules

#

vs editor about 2000

#

though cooking content will eat majority of time

low dust Feb 5, 2018, 3:57 PM

#

hmmm

#

I tried setup FASTBuild for UE4

#

build conf change doesn't throw errors, I can build updated UnrealBuildTool

#

but it's not using FASTBuild either

#

I wonder how I can debug UBT itself

#

as I suspect it's some path thing throwing it off

#

I guess I can put some debug texts here

#

ok, it doesn't find the exe

#

ok now moving to next issue

#

FASTBuild Error #1500 - Compiler() - Compiler detection failed. Unrecognized executable 'C:\Program Files (x86)\Windows Kits\8.1\bin\x64\rc.exe'.

low dust Feb 5, 2018, 4:19 PM

#

(that file exists)

#

and it throws same error even if I force it to point into 10 SDK

gloomy hamlet Feb 5, 2018, 5:16 PM

#

@low dust You can step through UBT in VS.

#

Just need to set it as the startup project, and set the command line args in the Project Settings| Debugging section.

low dust Feb 5, 2018, 5:17 PM

#

but if it's my startup project, how will I launch building?

#

anyway, I got bit further by tweaking the older FASTBuild.cs script

#

but no it's failing on it not finding any workers

#

even I have the fbuildworker running on this computer and it's listed in the exact same dir that script looks into

gloomy hamlet Feb 5, 2018, 5:20 PM

#

If you set UnrealBuildTool as startup project (obviously requires source engine solution), then right click UnrealBuiltTool project in Solution Explorer, hit properties, go to Debugging category, and under Command Arguments, fill in the UBT command line specifying the uproject you want to build, etc. Can't recall command line syntax off hand.

#

Then hit F5 and that will set off UBT building your project, with the debugger attached so you can use breakpoints in UBT code.

low dust Feb 5, 2018, 5:21 PM

#

I'm compiling the engine tho

gloomy hamlet Feb 5, 2018, 5:26 PM

#

Same thing, just need to find the correct args for building engine by command line.

low dust Feb 5, 2018, 5:29 PM

#

hmmm

#

I got it running now

#

I guess the remote worker isn't needed on the local computer

#

hence not detecting it

#

need to setup this on another comp at some point to see if I can run the distributed build

#

also, the script I'm running is really hacky now, may need to revisit the "new" version and see if I can fix it

low dust Feb 5, 2018, 6:46 PM

#

hmmm, now it stalled compilation into this

#

UnrealEngine\Engine\Source\Runtime\ClothingSystemRuntime\Public\NvClothIncludes.h(14): error C2059: syntax error: ')'

#

it's faulting on this line: PUSH_MACRO(check) macro itself is #define PUSH_MACRO(name) __pragma(push_macro(PREPROCESSOR_TO_STRING(name))) and // Turns an preprocessor token into a real string (see UBT_COMPILED_PLATFORM) #define PREPROCESSOR_TO_STRING(x) PREPROCESSOR_TO_STRING_INNER(x) #define PREPROCESSOR_TO_STRING_INNER(x) #x

#

regular VS2015 build without FASTBuild is fine with this code

grim halo Feb 5, 2018, 8:25 PM

#

as part of a project I'm probably going to implement reflection capture channels

#

do you think it would be useful to push to the main project?

#

( please don't tell me there already are lol )

#

cause we need to apply a different cubemap based on material/actor ( both would be fine, but I'll probably go for material )

grim halo Feb 6, 2018, 6:54 PM

#

static asserts all over the source say static_assert(MP_MAX == 29, "New material properties must have DoMaterialAttributesReorder called on them to ensure that any future reordering of property pins is correctly applied.");"

#

however this "DoMaterialAttributesReorder" doesn't seem to exist anywhere

spiral mortar Feb 6, 2018, 6:58 PM

#

@grim halo DoMaterialAttributeReorder

#

Engine\Private\Materials\MaterialShared.cpp:2800

grim halo Feb 6, 2018, 7:00 PM

#

thanks!

low dust Feb 6, 2018, 11:32 PM

#

oh crap

#

after two days fighting with FASTBuild and UE4

#

I got a hunch that there was something wrong with the FASTBuild itself, at least with these scripts that I have

#

so I actually downloaded older version of it (0.93) and it started working - kinda

#

at least now I get it to accept the compiler and it does distributed compiling with my 2 computers

#

it still doesn't seem to fill the cache dir so something is still probably off

#

of right, this script sniffs the buildmachine variable from environment, yeah I don't have the set

#

yeah, now the cache fills properly

#

now I'm only gettting tons of other errors 😄

#

I think these are for me trying to do non-unity build

low dust Feb 7, 2018, 3:14 AM

#

and to the macro issue

#

https://github.com/fastbuild/fastbuild/issues/256

GitHub

pragma push_macro error on visual studio 2015 · Issue #256 · fastbuild/fastbuild

I met syntax error when building unreal engine (4.16) with fastbuild on visual studio 2015
but it's ok without fastbuild.
PUSH_MACRO(check) // error: C2059: syntax error: ')'

the macro is implemen...

#

apparently MS has fixed that in VS2017 patch :/

#

doesn't really help when working on VS2015

#

so have to mod the macro itself

stable hemlock Feb 7, 2018, 7:40 AM

#

Is there any way to change all particles' lod distances globally based on user's graphics settings or do i have to rewrite ParticleComponents.cpp?

acoustic folio Feb 7, 2018, 9:16 AM

#

How do I change heap size for 4.18.3 for HTML5 builds? It used to be in packaging settings but now I don't see it..

low dust Feb 7, 2018, 10:37 AM

#

@ocean inlet hey man, you around?

#

been using your FASTBuild script, now on my day 3 trying to make this work

#

initial issue was that newest FASTBuild 0.95 and your script lead FASTBuild just not finding the compiler

#

when I went back to 0.94, it found it again

#

I mean, path and all was right, it just didn't accept it

#

but that's not my current issue

ocean inlet Feb 7, 2018, 10:39 AM

#

Yeah hoping to get around to updating the script to support 0.95 this weekend, thanks for the heads up!

low dust Feb 7, 2018, 10:39 AM

#

there's a reoccurring issue where I get these, after failing or cancelling the build: ```Severity Code Description Project File Line Suppression State
Error Failed to produce item: C:\Dev\UnrealEngine\Engine\Binaries\Win64\ShaderCompileWorker-ShaderFormatD3D.pdb ShaderCompileWorker C:\Dev\UnrealEngine\Engine\Intermediate\ProjectFiles\ERROR 1

#

I mean it doesn't happen every time

#

but it's happened few times now

#

I also get zero cache hits even it clearly writes the cache

#

not even if I do local build only

#

I'm using VS2015 which could be partial reason for my trouble

ocean inlet Feb 7, 2018, 10:41 AM

#

Does this only happen with cache enabled?

low dust Feb 7, 2018, 10:41 AM

#

hmmm, I'll try

ocean inlet Feb 7, 2018, 10:42 AM

#

I gotta head of for a bit, hopefully will get a chance to come back and give you a hand tonight if not ill hit you up tomorrow morning. Would love to fix it!

low dust Feb 7, 2018, 10:42 AM

#

oh, that probably is related to my other macro error actually

#

so nevermind that

#

VS2015 compiler still has that macro issue that they fixed on VS2017

ocean inlet Feb 7, 2018, 10:43 AM

#

Literally about to reference that issue

low dust Feb 7, 2018, 10:43 AM

#

it now breaks with nvidia volumetric lighting 😄

ocean inlet Feb 7, 2018, 10:43 AM

#

Damn, hoped they fixed it with 2015 😦

#

Got latest 2015 release?

low dust Feb 7, 2018, 10:43 AM

#

I replaced the nv cloth thing as in that fastbuild issue told

#

yeah

#

but they'll not patch this

ocean inlet Feb 7, 2018, 10:43 AM

#

Hmm bugger

low dust Feb 7, 2018, 10:43 AM

#

and VS2017 brings all kinds of other trouble

#

like I still need to compile physx manually, so I need VS2015 for it

#

I could mix tho

#

as it's separate dll compilation

ocean inlet Feb 7, 2018, 10:44 AM

#

Urgh, that sucks

low dust Feb 7, 2018, 10:44 AM

#

but VAX I have makes whole VS2017 totally unstable

ocean inlet Feb 7, 2018, 10:44 AM

#

got latest VAX? They had issues last year with 2017 + win 10 update

#

that's basically resolved now tho

low dust Feb 7, 2018, 10:45 AM

#

nah, no idea if current VA would work already, I refused to pay for it again once they left it broken for so long while I still had maintenance

ocean inlet Feb 7, 2018, 10:45 AM

#

yeah fair enough

#

aight, gotta head, I'll hit you up when im back online!

low dust Feb 7, 2018, 10:45 AM

#

and VS2015 was always way better experience for me

#

I'm really curious why the cache doesn't work

ocean inlet Feb 7, 2018, 10:45 AM

#

(sorry couldn't be around for longer)

low dust Feb 7, 2018, 10:45 AM

#

like, shouldn't it work even if you don't get one successfull build?

#

no worries 😃

#

right now my build only fails on the module where the nvidia volumetrics are in (which is main renderer thing probably)

#

but I haven't seen one single cache hit so far 😄

#

it could be related to the unity builds

#

but non-unity builds break in all directions with 4.18

#

oh wow, now that I re-enabled cache, it actually gets those hits

#

and on the second run after re-enabling the cache, it fails to hit them again

ebon jungle Feb 7, 2018, 10:53 AM

#

Hey guys, sorry to interrupt, not sure if this is the correct place to post this, but when I try and package my game, I'm getting these errors. This seems to be connected to the engine itself somehow? Have you had anything like this come up before?

📎 unknown.png

low dust Feb 7, 2018, 10:53 AM

#

@ebon jungle did you try #packaging ?

ebon jungle Feb 7, 2018, 10:54 AM

#

wow how did I miss that? 😂 thanks

low dust Feb 7, 2018, 10:54 AM

#

it's a new channel

low dust Feb 7, 2018, 2:50 PM

#

ok, first successful build with FASTBuild

#

it only compiled it for 3h 😄

#

not exactly fast but at least it did it

#

this is now 3x slower than without "fast"build

elder falcon Feb 7, 2018, 4:22 PM

#

what does fastbuild do that ubt can't already?

low dust Feb 7, 2018, 4:31 PM

#

make everything slower? 😄

#

well, if it would actually work like intended, it can cache already built classes and it can distribute the building across your network computers

#

but while this isn't throwing any errors anymore, I'm pretty sure this isn't working as intended

#

I changed 2 files from the ue4 renderer, other one was header, it's been building for 45 minutes since

#

I'm pretty sure unreals build system in general is just broken in 4.18

#

this is so stupid

#

it literally recompiles whole engine on almost all changes

#

like now, I changed files from renderer, I've seen this recompile all plugins too

#

like vehicle plugin

#

which is totally isolated from renderer

#

I get that unity-builds bundle bunch of things together but it should affect the plugins

#

at least, you'd not expect it to

#

I'll probably try to fix the non-unity build errors next

#

as this is unacceptable way to work

#

I can't just wait hour+ after changing few lines of code

#

now one hour passed on the iterative build

#

pretty sure this is completely broken setup

#

I do wonder if this is related to the issues I'm having

#

BFF file 'C:\Dev\UnrealEngine\Engine\Intermediate\fbuild.bff' has changed (reparsing will occur).

#

altho I'm pretty sure the FASTBuild.cs is designed to regen the file every time atm

#

it overwrites the old one at the beginning

gloomy hamlet Feb 7, 2018, 5:09 PM

#

@low dust UBT was always broken as far as I'm concerned. Recently I'm playing a little with Lumberyard and see similar ridiculous behaviour.

low dust Feb 7, 2018, 5:10 PM

#

yeah, LY building is royal PITA as well

gloomy hamlet Feb 7, 2018, 5:10 PM

#

I'm guessing companies that use Incredibuild with huge build farms just don't bother maintaining a build tool that works in a sensible way.

low dust Feb 7, 2018, 5:10 PM

#

CE building is ok'ish if you don't touch headers

gloomy hamlet Feb 7, 2018, 5:10 PM

#

Simpler to have a shit build tool and brute force it 😉

low dust Feb 7, 2018, 5:10 PM

#

most of their engine parts are isolated, even when they use unity-builds

#

yeah, that's my current impression as well

#

I just don't have farm of computers here

#

and my i5 struggles with UE4

gloomy hamlet Feb 7, 2018, 5:11 PM

#

Yep, same here.

low dust Feb 7, 2018, 5:11 PM

#

I have 3570k @ 4.2GHz, takes 1h 5m for full regular build on 4.18

#

my fastbuild conf was way slower

#

like 3x slower 😄

#

but it definitely didn't use the cache either

#

it did write to it

#

but it couldn't read from it

gloomy hamlet Feb 7, 2018, 5:14 PM

#

If I was writing a build tool, the first thing I would do is make sure that it logged at every point it decided something had been invalidated, and why.

#

Without that, it's basically impossible to understand why it's taking so long and what the problem is.

low dust Feb 7, 2018, 5:20 PM

#

I'd really need to make some bigger changes on the renderer but it's never happening with these build times

#

it would take 6 months to get the things done because I'd just be waiting for the engine compile all the time

low dust Feb 7, 2018, 6:10 PM

#

ok so, ditched the fastbuild for now, trying to get the non-unity build working on regular build-system first

#

might try fastbuild again if I get this figured out and it's still slow

#

I mean, initial build on non-unity will definitely be slower but like mentioned, I mainly care about the iteration times

#

first run can take hours, I wouldn't care

elder falcon Feb 7, 2018, 6:12 PM

#

I don't think ubt is causing your trouble with the rebuilds

#

it works very well to figure out which files need to be built and which not

low dust Feb 7, 2018, 6:12 PM

#

not with 4.18 it does

elder falcon Feb 7, 2018, 6:12 PM

#

the problem is most likely that someone decided to include a renderer header elsewhere in the engine

low dust Feb 7, 2018, 6:12 PM

#

I've had this issue on every 4.18 build I've made

elder falcon Feb 7, 2018, 6:12 PM

#

it'd be useful if it could print the include graph and tell you why it is rebuilding everything, though

#

...maybe it can and we just don't know how to make it do that

low dust Feb 7, 2018, 6:15 PM

#

it definitely wasn't this bad on previous unreals

#

it's never been great

#

but it's totally broken now

elder falcon Feb 7, 2018, 6:16 PM

#

it could just be that in 4.18 there are a bunch more includes that cause it to rebuild everything even though the include is never used

low dust Feb 7, 2018, 6:23 PM

#

going to try this now ```xml
<?xml version="1.0" encoding="utf-8" ?>
<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
<BuildConfiguration>
<bUseUnityBuild>false</bUseUnityBuild>
<bUsePCHFiles>false</bUsePCHFiles>
<bUseIncrementalLinking>true</bUseIncrementalLinking>
</BuildConfiguration>
</Configuration>

#

also have modded the cpu multiplier at 2 and priority above normal elsewhere

#

people suggested it helped on the compile times

#

altho I don't really expect huge difference on multiplying the task amount on this i5 as it doesn't have those extra hw threads

elder falcon Feb 7, 2018, 6:25 PM

#

probably won't help much then

#

if you upgrade to a 7820X, the compile times get more in the "acceptable" range

low dust Feb 7, 2018, 6:25 PM

#

I did check the task manager on regular builds and it does dip the cpu utilization all the time when it fetches new things to compile

elder falcon Feb 7, 2018, 6:26 PM

#

then it just wastes 12 min for an accidental full rebuild

low dust Feb 7, 2018, 6:26 PM

#

sure, 7820X would require me to have 1200€ spare extra cash tho

elder falcon Feb 7, 2018, 6:26 PM

#

instead of hours

low dust Feb 7, 2018, 6:26 PM

#

otherwise I'd do it

#

it would totally pay itself back too

#

just don't have budget for it atm

#

thing is, I don't need more CPU power for anything but for this bloody UE4 compilation as it's so broken

elder falcon Feb 7, 2018, 6:27 PM

#

the vs2017 compiler also seems to be faster

low dust Feb 7, 2018, 6:27 PM

#

if it did iterative build properly, this cpu would be just fine

#

could be, but I'm not using it

elder falcon Feb 7, 2018, 6:27 PM

#

why not? vs2017 is faster in so many ways

#

much better to work with

low dust Feb 7, 2018, 6:28 PM

#

I've just had very bad experience on VS2017 so far

#

and VA version I got is garbage on VS2017

#

it makes whole VS unstable

elder falcon Feb 7, 2018, 6:28 PM

#

huh

#

my VA works perfectly fine

low dust Feb 7, 2018, 6:28 PM

#

sure, you probably still have active maintenance plan

#

mine ran out last spring

elder falcon Feb 7, 2018, 6:28 PM

#

oh

low dust Feb 7, 2018, 6:28 PM

#

they didn't fix the issues for months

#

didn't want to pay again for that

#

and since VS2015 works just fine with VA, been happy with it

#

but that's just one thing

#

there are plently of other issues with VS2017

elder falcon Feb 7, 2018, 6:29 PM

#

you could use vs2015 to work and have ubt build with 2017

#

both can be set independently

low dust Feb 7, 2018, 6:30 PM

#

not sure if I really find it worth the trouble

#

few minutes isn't issue

#

one hour recompile every time is

elder falcon Feb 7, 2018, 6:30 PM

#

there must be some way to get it to export the whole include graph or why it is rebuilding a certain file

low dust Feb 7, 2018, 6:30 PM

#

tbh, I've seen like 30 min recompiles on 4.18 on some changes, where I haven't touched any headers 😄

elder falcon Feb 7, 2018, 6:31 PM

#

that'd probably help find out what causes this

low dust Feb 7, 2018, 6:31 PM

#

it doesn't really help to know what causes it if things still depend heavily to eachothers, I can't keep fixing everything for epic if I want to get my own work done

elder falcon Feb 7, 2018, 6:32 PM

#

yeah, but if the problem is includes all over the place then it's not really ubt's fault and a different build system can't really fix it either

low dust Feb 7, 2018, 6:33 PM

#

if that's the case, then yeah

#

but I'll see how this goes

#

if non-unity build with no pch's solve the iteration time, it's pretty clear where the issues lie

#

and in such case, I wouldn't even care

#

I only want to stop wasting hours of my time for no good reason

#

or weeks actually

#

even when this thing worked better on 4.15, it still took me like 2 weeks to make one modification to physx on the engine side, just because compilation times were so horrible

#

it was 2 day job

#

after that I pretty much stopped using unreal

#

as it was just too painful

#

now looking at it again but it's only gone worse

elder falcon Feb 7, 2018, 7:04 PM

#

well, make sure to tell everyone if there is a magic fix :D

low dust Feb 7, 2018, 7:12 PM

#

now kinda stuck at non-unity build for fixing nvidia volumetric lighting

#

it says GNVVolumetricLightingRHI is undefined

#

but it does include the header where it's defined

#

I don't quite understand the code either

#

they pass the pointer for it

#

but they never put anything to it on the code

#

they only call functions for it but only assignment to the ref is nullpointer

#

which makes very little sense

grim halo Feb 7, 2018, 8:28 PM

#

there's something I don't get about MaterialTemplate.ush

#

it almost seems like the code to compute the properties ( from TranslatedCodeChunks ) is written twice in it?

#

once as an assignments to PixelMaterialInputs, and once inside the GetMaterial*() functions

#

( like GetMaterialCustomData0() )

#

it might be because there's individual functions for each parameters and a function that does them all ( CalcPixelMaterialInputs ) but I'm not sure

ocean inlet Feb 7, 2018, 9:07 PM

#

@low dust I'm back, did you manage to find a solution to the problem?

low dust Feb 7, 2018, 9:08 PM

#

well, I got it to compile

ocean inlet Feb 7, 2018, 9:08 PM

#

Sounds like it was a lot slower tho :/

low dust Feb 7, 2018, 9:08 PM

#

but it didn't really use cache properly

#

yeah

#

3x slower on initial build

#

and on iterative build I just cancelled after 1.5h or so

#

it was nowhere near done

#

now trying to do non-unity build without pch and incremental linker enabled

#

this is super slow to build as well

#

but in theory, this should help on iterative builds at least

#

which is my main interest here as I want to modify UE4

#

@ocean inlet do you actually get cache to work with ue4 builds?

#

I also wonder if this is some regression with VS2015

ocean inlet Feb 7, 2018, 9:12 PM

#

Yeah I did, tho i stopped using it as much as the primary reason for me doing it was so when our build machine builds latest change set it would cache those results and everyone else benefits.

Butttt problem with caching is it requires everything to be the exact same, build config, compile type, same invoking call, same directory. Which just wasn't viable

#

In the office I don't use it but at home I do

low dust Feb 7, 2018, 9:12 PM

#

well, I couldn't even get it to work on local build

#

compile the thing again and it recompiled everything, usually all caches missed

#

there was like 22GB of cache in the folder

ocean inlet Feb 7, 2018, 9:14 PM

#

There is a bug??? either with my script or 4.18 where fastbuild is sometimes doubling actions. e.g. wanting to compile the same thing twice. Fastbuild is smart enough to know to skip it but still slows down the build a little bit.

As for your caching issue,is it a local cache or remote? (Where it is stored)

low dust Feb 7, 2018, 9:14 PM

#

I tried both

#

local directory and a network path

#

didn't make any difference

ocean inlet Feb 7, 2018, 9:15 PM

#

What the, and your compiling it the exact same way both times?

low dust Feb 7, 2018, 9:15 PM

#

and like mentioned earlier, I did see it using the cache once

#

right after I had disabled cache and enabled it again

#

but after that it never saw it again

ocean inlet Feb 7, 2018, 9:16 PM

#

Hmm and your sure cache mode was set to read or readwrite?

low dust Feb 7, 2018, 9:16 PM

#

it wouldn't write there if it was read only

ocean inlet Feb 7, 2018, 9:16 PM

#

yeah just making sure it isn't write only

low dust Feb 7, 2018, 9:16 PM

#

I initially set it from the script to readwrite

#

but later defaulted it back to wahat your script did and set it on the env var

#

I did get the distributed building working tho but it's not really helping as I don't have a farm of computers here, only one additional i3 😄

#

I didn't use it in the end

#

as I read it might confuse the cache (I did try to setup similar SDKs and paths tho)

#

I also wiped the cache after disabling distributed builds

#

so that wasn't confusing it either

ocean inlet Feb 7, 2018, 9:20 PM

#

Hmm, that's odd.

At some stage I'm most likely going to have to go back and re-write the parsing/.bff file generation. It was written by the previous maintainer and I haven't ever touched it. Mostly been dealing with engine version suport and dealing with VS changes.

I have noticed it's not as fast as it used to be, which is a sure sign something is slipping

#

haha yeah fair enough. Distribution is easy enough, caching has been a pain just understanding what exactly it wants

low dust Feb 7, 2018, 9:22 PM

#

yeah, my biggest pain with UE4 is in the iterative builds, I just want that to be as fast as possible

ocean inlet Feb 7, 2018, 9:22 PM

#

If you haven't read it already would recommend having a geeze through here
https://github.com/fastbuild/fastbuild/issues/245

GitHub

How does FastBuild determine what data can be read from the cache? · Issue #245 · fastbuild/fastbuild

Sorry for placing this kind of question here let me know if there is more of an appropriate place.
I am slightly confused as to how FastBuild determines what can be read from the cache and what can...

low dust Feb 7, 2018, 9:22 PM

#

on default 4.18, engine pretty much recompiles itself fully on changes on the renderer

ocean inlet Feb 7, 2018, 9:23 PM

#

Just to check all the requirements are met for the caching to occur

low dust Feb 7, 2018, 9:23 PM

#

I read that and bunch of others

ocean inlet Feb 7, 2018, 9:23 PM

#

roger

low dust Feb 7, 2018, 9:23 PM

#

but in my case, I couldn't even get the caching work on single computer

#

I can understand it would be more difficult on distributed builds, due to how it checks the hash

#

but it shouldn't affect local builds

ocean inlet Feb 7, 2018, 9:24 PM

#

I agree

low dust Feb 7, 2018, 9:28 PM

#

hmmm, this non-unity build thing is kinda stupid too

#

it also recompiles tons of things even if it's just linked these

#

and I haven't altered the header files that they use

ocean inlet Feb 7, 2018, 9:30 PM

#

Same behaviour take place without fast build?

low dust Feb 7, 2018, 9:30 PM

#

I need to stop the compilation to fix the missing forward declarations and includes with it, so it also recompiles after that bunch of things that it already compiled on the previous run

#

oh I didn't even try to make non-unity work with fastbuild

#

this is vanilla now

#

FASTBuild gave tons of additional errors I had to solve, I wanted to get this non-unity thing compile on stock build setup first so I'll not get stuck on things for too long

#

might try fastbuild again with this once I get all these issues solved

ocean inlet Feb 7, 2018, 9:33 PM

#

no worries

low dust Feb 7, 2018, 9:37 PM

#

wonder if I should make a PR for these non-unity build issues

#

I mean, you are supposed to be able build the engine this way out of the box too

ocean inlet Feb 7, 2018, 9:40 PM

#

are they mostly IWYU issues?

low dust Feb 7, 2018, 9:47 PM

#

yeah

#

unity builds let you forget some of those

#

and when I fix some, it takes like 5 minutes now till the compiler gets to that point again

#

as it recompiles some of the earlier tools again every time

#

some of these are on the nvidia gameworks things tho

#

like now trying to fix flex

ocean inlet Feb 7, 2018, 10:03 PM

#

yeah thought as much, they can be a right pain. Suprised they haven't made the switch over, slow and tedious process to do but should get them decent gains in compilation time

acoustic folio Feb 8, 2018, 6:18 AM

#

Is there a github page for 4.19 preview that I can download as source? (zipped)

gloomy hamlet Feb 8, 2018, 7:35 AM

#

@acoustic folio https://github.com/EpicGames/UnrealEngine/tree/4.19.0-preview-4

#

To get there you click the branch dropdown on the left, then switch to 'Tags'.

acoustic folio Feb 8, 2018, 7:42 AM

#

Aha! Thank you!

low dust Feb 8, 2018, 9:28 AM

#

@acoustic folio all ue4 releases are listed on repos releases: https://github.com/EpicGames/UnrealEngine/releases you need to just expand the tags on the top to see the newest previews

acoustic folio Feb 8, 2018, 9:28 AM

#

@low dust thanks i missed the tags part!

low dust Feb 8, 2018, 9:29 AM

#

oh wow, I didn't know about the tags either

#

this is even easier

#

so, day 4 on my "wish I'll get quicker iterative builds" journey

#

still fixing the non-unity references here

#

Flex has been PITA to patch as they haven't done proper forward declarations/includes for any of their components, their setup has only worked as to unity-build has stuffed all these files together as one compilation unit

#

I really should have started with stock UE4 source code for this test 😄

#

I mean, this is silly

#

just didn't expect to get this much extra work from gameworks

low dust Feb 8, 2018, 10:09 AM

#

I wonder why the full build always rebuilds certain engine tools, like UnrealWatchdog and UnrealFrontend

#

it literally does those every time again

#

now I've just right clicked UE4 in the solution and build it alone because of this

grim halo Feb 8, 2018, 10:11 AM

#

Pls share when you're done :/

low dust Feb 8, 2018, 10:12 AM

#

I'm spamming the channel too much?

final quarry Feb 8, 2018, 3:53 PM

#

Has anyone else ran into the issue where using a source build of the engine, you can no longer cross-compile for linux because UnrealBuildTool won't specify linux targets? It worked fine with the downloaded version of 4.18.3

low dust Feb 9, 2018, 10:00 AM

#

@final quarry by default setup, you only get the dependencies for the platform you are building for + mobile and web

#

I dunno if this is still up-to-date: https://wiki.unrealengine.com/Compiling_For_Linux

but like mentioned there, you need to be sure you've got everything set before you run generate project files thng

final quarry Feb 9, 2018, 12:06 PM

#

@low dust I got it working eventually, it was an issue with the environment variable not refreshing on windows server

low dust Feb 9, 2018, 12:07 PM

you usually need to boot the computer after setting those

astral sapphire Feb 9, 2018, 1:59 PM

@low dust my bad

#

but I my buildconfiguration.xml is now:

        <bUseIncrementalLinking>true</bUseIncrementalLinking>
    </BuildConfiguration>

(still trying non-unitty build)

#

basically had to add that bAllowXGE

#

still concerned about those errors tho

astral sapphire Feb 9, 2018, 2:00 PM

#

hmm...i think i've seen similar error

low dust Feb 9, 2018, 2:01 PM

#

I also got one other error many times in the beginning that said it couldn't find manifest for amd64/lib.exe on compiler

#

I think did that for UE4 tools

#

but yeah, it's definitely doing something now, you know where the cache is stored?

low dust Feb 9, 2018, 4:50 PM

#

@astral sapphire can you control the cache size of does it cache everything?

#

asking because this is recompiling everything again 😄

astral sapphire Feb 9, 2018, 5:06 PM

#

@low dust it is controlled by ue4 project setup

low dust Feb 9, 2018, 5:08 PM

#

is there any doc for it?

astral sapphire Feb 9, 2018, 5:09 PM

#

probably not, try to google UnrealBuildTool

#

or Unreal Build System

this is only official doc I found https://docs.unrealengine.com/latest/INT/Programming/UnrealBuildSystem/Configuration/

Hey yall, I'm new here had a question that I was hoping someone could help me out with.. I'm using 4 vive trackers + 2 vive controllers, and as of recently have been getting crashes when all of them are turned on. Looked into it, apparently theres some issues with UE with more than 3 trackers +2 controllers. Found the solution was to rebuild the engine and to add a couple of lines of code as perscribed by https://issues.unrealengine.com/issue/UE-54387 - I'm getting more than 200 errors when trying to build. Can provide whatever is needed to figure it out.

low dust Feb 10, 2018, 5:01 AM

#

oh snap

#

Octobuild finally works

#

and I get iterative builds in less than minute now

#

this is pretty amazing

#

vs the old 30-60minute wait

#

well, fast for cpp changes anyway

gloomy hamlet Feb 10, 2018, 5:23 AM

#

@low dust Sounds great. I haven't been following everything, not heard of Octobuild. Did you give up on fastBuild and try integrating something different?

low dust Feb 10, 2018, 5:35 AM

#

yeah

#

I still feel like FASTBuild should work the same but there's something that's going wrong with it on my conf

#

it's not really getting cache hits at all

#

header changes still last longer

#

that's expected tho

#

testing it atm

#

one major difference with FASTBuild and Octobuild is that fastbuild can do distributed building across the network

acoustic folio Feb 10, 2018, 5:47 AM

#

Anyone have experience with HTML5 multiplayer games?

gloomy hamlet Feb 10, 2018, 5:51 AM

#

So what is Octobuild adding/changing with respect to standard UBT behaviour?

low dust Feb 10, 2018, 6:07 AM

#

cache mainly

#

I honestly don't know why default UE4 build rebuilds the whole bloody engine

#

on cpp changes

gloomy hamlet Feb 10, 2018, 6:11 AM

#

Yeah, it definitely isn't too smart. But does that mean you've essentially completely replaced UBT's logic for deciding what to compile?

#

Or Octobuild just sits on top and says "No, actually I'm not gonna build that file again, have this .obj"?

low dust Feb 10, 2018, 6:13 AM

#

latter I presume

#

altho

#

I didn't really get long linker stage

#

in the end, if this keeps working, I don't really care how it does it 😄

#

wonder if there's something that could be done for the rebuild time on header change

#

like, would disabling pch help there?

gloomy hamlet Feb 10, 2018, 6:18 AM

#

Could do, I still haven't fully got my head around how UE4's shared pch stuff works; how and when it recalculates what to put in them.

#

You can try just disabling it in the Build.cs file of the module you're working on (mostly Engine, presumably). See if that helps.

#

But you will always be fundamentally limited by the fact that UE4's dependencies are still a mess; IWYU got rid of monolithic includes, but doesn't change the fact there are heaps of headers being included all over the place that wouldn't need to be if stuff was better organised.

grim halo Feb 10, 2018, 7:54 AM

#

found somewhere to sneak in my reflection environment index

#

gbufferb.a is a 32 bit float if I understand correctly

#

it's being used to encode shadingmodelID and selectiveoutputmask, two numbers that only take up 4 bits each

#

so there's 24 unused bits for parameters like that ( mine should only take 8 so now it's 16 )

#

oh no wait, you can only use the mantissa with the current method

#

23-8=15, 15-8=7 so still there's space for almost two chars

astral sapphire Feb 10, 2018, 7:59 AM

#

@gloomy hamlet octobuild is Incredibuild replacement, and UBT uses Incredibuild for caching...

#

@low dust i've reinstalled Octobuild and it doesn't work...-_-

#

same error about utf

gloomy hamlet Feb 10, 2018, 8:04 AM

#

Thanks. Okay that kind of fits with what I was thinking I guess. If they're relying on Incredibuild for that stuff, then it figures that they didn't bother to implement decent detection of what needs recompiling directly into UBT. So everyone without Incredibuild suffers...

astral sapphire Feb 10, 2018, 9:04 AM

#

@gloomy hamlet incredibuild is free for 4 machines

low dust Feb 10, 2018, 9:04 AM

#

no it's not

astral sapphire Feb 10, 2018, 9:04 AM

#

@low dust it is

low dust Feb 10, 2018, 9:04 AM

#

you get free trial that works for 4 machines I think

#

after 30 days, it's only local build

astral sapphire Feb 10, 2018, 9:05 AM

#

trial is permanent

#

oh...yep, i can't confirm it's not

#

i'm using it only locally

low dust Feb 10, 2018, 9:06 AM

#

The maximum yield the trial gives you is for 32 cores (4 machines x 8 cores).

#

and on other page For the first 30 days, you can freely use all the IncrediBuild suite of solutions with no limitation on number of builds, and on any other capability it provides. You can run compilations or accelerate your testing, code analysis as well as rendering, shading or on any other development tool you are using. The free license allows you to use up to 4 agents/machines with the ability to use up to 4 logical cores on each agent/machine for 30 days (that’s pretty much 720 potential build hours).

#

it's possible that doc is outdated

#

both were on the official website

#

does the incredibuild make local builds faster?

#

I didn't care to test as you need to sign up for it

astral sapphire Feb 10, 2018, 9:13 AM

#

📎 screenshot.1518253798.png

#

pwahahah

#

@low dust i think...i've used it only several times, since i prefer octobuild

#

IB is chunky

low dust Feb 10, 2018, 9:15 AM

#

I'd be more interested on the tools it ships with

#

if they could analyze the painpoints of the build process

gloomy hamlet Feb 10, 2018, 9:15 AM

#

Interesting, hadn't even thought to look into a free version.

#

So @low dust did you have to modify UBT to work with Octobuild, or it can directly drop in as an alternative to Incredibuild?

low dust Feb 10, 2018, 9:16 AM

#

no mods on ue4 side for that

#

it uses incredibuilds access point

#

I had to force it on in one engine build from the buildconfiguration.xml tho

#

but on 3 others I've tested it, it has been used automatically

#

I think the one where it didn't had some leftovers from fastbuild conf

#

but I should have cleaned them up tho

#

so, go figure

astral sapphire Feb 10, 2018, 9:21 AM

#

i wish someone from Epic could help...

gloomy hamlet Feb 10, 2018, 9:25 AM

#

So maybe one of you can clarify this for me. Is there some fundamental difference between compilation caching, and just knowing what source/config has been touched and implies a necessary recompile? Because to me, that's just the fundamental, basic point of a build tool.

#

So it seems like this is basically a fix for the shortcomings of UBT rather than something distinctly different?

low dust Feb 10, 2018, 9:25 AM

#

in my use there is

#

I think 4.18 UBT is totally bugged without incredibuild

#

or it's something on my engine repo's build setup that breaks it (there are some gameworks stuff in there so not vanilla)

#

it literally recompiles the engine if I touch any cpp file

#

including all tools

#

with octobuild, it works like you'd expect

#

it only seems to compile what has truly changed

#

I expect same for incredibuild

astral sapphire Feb 10, 2018, 9:28 AM

#

yep, i've noticed it too, 4.17 was compiling fine

low dust Feb 10, 2018, 9:28 AM

#

altho can't tell from practise

astral sapphire Feb 10, 2018, 9:28 AM

#

4.18-20 not

gloomy hamlet Feb 10, 2018, 9:28 AM

#

Yeah that's kind of what I mean. It seems an extra level of caching wouldn't do anything if the build tool just worked sensibly.

low dust Feb 10, 2018, 9:29 AM

#

indeed

astral sapphire Feb 10, 2018, 9:32 AM

#

i've also found

r.XGEShaderCompile = 1

in ConsoleVariables.ini

low dust Feb 10, 2018, 9:32 AM

#

oh right

#

that's for shaders

#

you can actually distribute the shader compilation across the network if you have distrubuted build setup

#

wonder if octobuild can cache that

#

altho

#

those shaders tend to not recompile on same build anyway without file change

#

so there's really no need for that

astral sapphire Feb 10, 2018, 11:59 AM

#

anything new in 4.20 ?

static spoke Feb 10, 2018, 1:49 PM

#

Any eta on it?

low dust Feb 10, 2018, 1:55 PM

#

they haven't even updated 4.19 target to trello

#

I don't think current master even has much 4.20 specific stuff

#

saw some framework commits

#

and tweaks to animations and physics but nothing major

elder falcon Feb 10, 2018, 4:20 PM

#

how do you guys manage to bug your ubt

#

if I change a cpp file, it excludes that one from the engine unity build, rebuilds the one file and relinks the module

#

works fine

astral sapphire Feb 10, 2018, 4:37 PM

#

@elder falcon um...what if you change slate.h ?

elder falcon Feb 10, 2018, 4:38 PM

#

are you sure you mean that file? there doesn't seem to be anything worth changing in it

#

https://i.imgur.com/hk6BfXt.png

Imgur

#

and nothing is including it

#

changing a header is different from a cpp file anyways

#

if you change a header you have to rebuild all files that directly or indirectly include it

#

nothing ubt can do about that, it's just how cpp works

astral sapphire Feb 10, 2018, 5:09 PM

#

@elder falcon oh, yeah sorry, i was talking about slatecore...
how ofter do you changing cpp w/o changing headers?

low dust Feb 10, 2018, 6:28 PM

#

@elder falcon are you using 4.18?

#

also, my issues are on cpp changes

#

which is absurd

#

one line change in SceneVisibility.cpp for example and UBT builds again all tools, all plugins, the whole engine

#

that cpp has no connection to vehicle plugin for example 😄

#

once I put octobuild into equation, it finally started working like you'd expect

#

do note that I didn't have this issue while working on older ue4 code, sure it wasn't instant back then but it sure didn't recompile always with your neighbours cat and dog in the process

elder falcon Feb 10, 2018, 6:37 PM

#

yeah

#

did you try building with vs 2017?

low dust Feb 10, 2018, 6:38 PM

#

nope

elder falcon Feb 10, 2018, 6:38 PM

#

maybe it's only broken for outdated vs

low dust Feb 10, 2018, 6:38 PM

#

could be vs2015 issue

elder falcon Feb 10, 2018, 6:39 PM

that's probably the largest difference between our setups

i'm not sure if this is appropriate for engine-source or where it's appropriate - but i'm having a level chunk refusing to load into Content Browser

grim halo Feb 11, 2018, 9:33 PM

#

is it possible to load completely different images as different mipmaps of a texture

#

and then use that as a kind of "3D texture" that let's you select different those completely different images based on the mipmap index?

astral sapphire Feb 11, 2018, 10:12 PM

#

@grim halo it is possible, but useless...each mip has scale of 2, for 3d texture use 2d uv tiling ...p.s. this is a wrong channel for that kind of question, use #graphics

grim halo Feb 11, 2018, 10:13 PM

They usually accept PRs quicker based on their importance to the codebase and how closely they follow Epics coding standards.

Heh. Epic should test what they put into UE4 promoted branch better

#

ERROR: UnrealEngine\Engine\Source\Runtime\Core\Core.Build.cs(149,5) : error CS0103: The name 'PublicDefinitions' does not exist in the current context etc

#

Might just be a specific of upgrading though

#

I'll try to rebuild UE4 project files first, compile that so it updates unrealbuildtool, then try again

#

I think that's the reason actually. In which case, boo, more UBT changes that break things

radiant hazel Feb 13, 2018, 12:48 AM

#

Well, that was user error to some extent, but there has to be a fast way to rebuild UHT/UBT without generating project files for the entire engine (and starting an engine rebuild)

#

If someone knows that, poke me

elder falcon Feb 13, 2018, 4:25 AM

#

can't you just right click uht in the solution explorer and rebuild it?

#

under programs

#

same for ubt

#

@radiant hazel

radiant hazel Feb 13, 2018, 5:17 AM

#

@elder falcon not really! At least it doesn't seem that way. I think I need to select "quick build" option

thick storm Feb 13, 2018, 10:02 AM

#

they update code

#

but they don't update binaries for UBT/UHT

#

GenerateProjectFiles.bat in engine soruce will work

#

you can then manually rebuild UBT

Hey all, since building 4.20 from source I’m having an issue

#

When I right click a ue4 project file, the launch game, generate visual studio project files, and switch unreal engine versions options have become disassociated. Windows asks me what I want to use to execute them

#

How can I reassociate these, and what should these options reference?

elder falcon Feb 13, 2018, 7:24 PM

#

try running setup.bat again or binaries/win64/unrealversionselector.exe

steel birch Feb 13, 2018, 7:26 PM

#

Lol, well that was simple enough.. thanks

#

Those two operations have seemed to run a find and replace in the windows registry. All the old 4.18 references now direct to the new 4.20 directory

Hey guys, heard there were multiple versions of the ini files such as Engine

I have found BaseEngine.ini in the Engine/Config folder
I have found DefaultEngine.ini in the Config folder

But I heard someone from epic in some article I can't find again say that there were considering having Per-User config files, anyone knows if that's implemented? And if yes, where can I set those values from the editor please? Thank you very much

hey everyone ! Do I need to compile my own source if an engine value command returns that its read only in the console ? (and edit that value, or make it writeable)

slender saddle Feb 16, 2018, 12:25 AM

Yeah UE 4.20 needs a new foliage setup. 😉

gray glade Feb 16, 2018, 12:35 AM

#

@royal glacier I don't think so, but maybe that value can't be changed at run time - there's probably an INI file you need to set it in.

#

Considering it's a dimension for a texture atlas of some sort, I wouldn't expect you to be able to arbitrarily change it whenever - that's involve reallocating a new buffer and potentially re-atlasing everything.

royal glacier Feb 16, 2018, 7:53 AM

@gray glade thanks for the feedback on that matter. So basically I'm stuck with a "kinda" small Distance Field memory pool ? 😦 that sucks a bit, I wonder how Epic managed to get so much stuff in Fortnite while using so much DF meshes in their scenes.

gray glade Feb 16, 2018, 7:53 AM

#

No?

#

I suggested it couldn't be changed at runtime.

#

That you could probably change it in an ini file.

royal glacier Feb 16, 2018, 8:15 AM

#

uh I misread, my bad

#

funny though

#

cause there's a command to reallocate the buffer 🤔

#

r.DistanceFields.ForceAtlasRealloc

#

at least I guess that's what it does

#

there's literally no doc on all of the advanced DF stuff

#

@gray glade awesome it is indeed writeable in the .ini

#

now I can get wild 😄

hollow timber Feb 16, 2018, 3:31 PM

Hello ! A quick question about geometry shader, if I want to output a TriangleStream, do I have to match the format used by the vertex factory used by this shader ? Or do I need to have a custom format and then use it in my pixel shader ? (I don't really need to make special operations in my PS so I don't really need one)

#

I think I have a misinterpretation about where the new data is going. Is it adding to existing vertexes of the mesh or do I need to post process it and add it somewhere ?

low dust Feb 16, 2018, 3:56 PM

#

@final quarry is that some modified build?

#

I mean, you should mentioned that as it could be related to your issue

Hello guys!! Can you please advice me great learning resource about how to make my own game engine like Unreal? I'm fine with Unreal, but I would love to know how to make it by myself. Thanks!

elder falcon Feb 17, 2018, 9:25 PM

#

there is no way to create something even remotely comparable to unreal on your own

gray glade Feb 17, 2018, 9:28 PM

#

Honestly, best bet is to look at UE4 itself and see how it organizes things, learn why, and use that knowledge to write your own. You'll need to abstract windowing (or lack thereof) from the actual platform, abstract what you use to render and implement D3D and OpenGL renderers, write your own scene management, write your own math, collision, and physics libraries or integrate something like PhysX or Bullet or Havok, and so on and on and on.

#

Audio, networking, file system, input

proper lantern Feb 17, 2018, 10:10 PM

#

Maybe there some books or source code that were been used by Epic games to start the engine programming. I'v found a lot resources related to graphics (Siggraph, GPU pro, Real-time Rendering, Physically Based Rendering from Theory to Implementation, etc, but how I can make platform abstraction?), some about collission detection, Newton dynamics and particles (Baraff's papers, Numerical Simulation in Fluid Dynamics: A Practical Introduction, etc), but nothing related to game engine audio (except XAudio2 documentation, but how I can make my own cross-platform audio engie on top it?), also nothing related to scene management, file system, memory allocation, job manager, entity system, flow-graph, input, network, scriptic system like Blueprints, node-based editor, my own gui framework. All these things are floating apart somewhere, but I can't find any info about how devs learn them and use them in their engines.

gray glade Feb 17, 2018, 10:16 PM

#

The Unreal Engine is 20 years old.

#

It's passed though hundreds, if not thousands, of programmers' hands.

#

You won't find "the books" that were used, because it's the collected knowledge of 20 years of hundreds of authors.

proper lantern Feb 17, 2018, 10:39 PM

#

Hundreds/thousands programmers developed Unreal? Wow! But how new people at Epic figure out how to improve the engine? Looking at the engine source code I can't undestand the code. And I guess guys at Massive didn't saw Unreal source code to make their Snowdrop engine, so I wonder how new people find the way in this field.

timid hollow Feb 17, 2018, 10:44 PM

#

like any large code base, you start small and work yourself in and get some guidance from the older programmers, its not like they completely replace there staff every year

This sort of guidance is what I need probably.

hollow timber Feb 18, 2018, 11:49 AM

@proper lantern The book Game Engine Architecture from Jason Gregory is pretty nice, it explains many different systems (https://www.amazon.fr/Engine-Architecture-Second-Jason-Gregory/dp/1466560010)

grim halo Feb 18, 2018, 6:52 PM

#

I'd like to up @hollow timber 's question

#

in general, if we want to modify the geometry in the geometry shader ( say I want to make 3d ripples on water, with more triangles where the ripples are stronger ), can that be done in the editor or do we have to do something (w)hacky in the usf's?

hollow timber Feb 18, 2018, 7:10 PM

#

You have a tesselation feature in editor, where you can specify new vertex offsets etc... I think it works well, but in my case I would like to access custom hash grid data... I could use the material editor but I think it's more clearer by coding it (maths operations in blueprint tends to be very confusing/ugly).

grim halo Feb 18, 2018, 8:13 PM

is it normal for two surfaces reflecting each other with SSR to shift to red with time?

hollow timber Feb 19, 2018, 10:44 AM

You can ! I would advise to keep the pdb you generated the version for your coworkers in case they have crash and want to send you crash report, this way you can still inspect the callstack if you have the corresponding pdbs

if you really got the 4.18.3 sources something is not right because that should have been fixed in 4.17 with SHA-1: de3d9cced72bd423dd08b4eba8110799dbb12b85

#

But if that's the only issue you are having, you could just change line 716 to D3D12_STATE_CACHE_INLINE void SetPipelineState(FD3D12PipelineState* PSO)

(take out FD3D12StateCacheBase:: from that line)

can I set my project config to Debug Editor while having engine as Development Editor?

grim halo Feb 20, 2018, 11:16 AM

Well of course you have to change engine code.. but those people might have done it in other more hacky ways from what I've seen

elder falcon Feb 20, 2018, 2:24 PM

#

@sick basin use DebugGame Editor config

#

builds the engine for development and your projects for debug

lost linden Feb 20, 2018, 2:33 PM

#

@elder falcon problem is you need both development and debug. There are things you can't do with a debug build alone apparently.

elder falcon Feb 20, 2018, 2:34 PM

#

like what things?

#

I usually switch between development and debuggame, a full debug build would only be required for debugging engine code

lost linden Feb 20, 2018, 2:35 PM

#

like when a rebuild is required internally, it does development build, it fails if its not present initially

#

I cant remember the exact case I had but a few weeks ago I setup 4.18 with a debug build only to save space. Something happened that triggered the need for a rebuild, but it would look for development build and not debug. So I had to build a development build before I could continue

elder falcon Feb 20, 2018, 2:36 PM

#

debug/debuggame can only be started from vs

#

if you try to open the editor normally it'll load development binaries

#

might have been the issue

lost linden Feb 20, 2018, 2:39 PM

#

oh thats it. I added a new class to a blueprint project to convert and it required the rebuild as development. So yeah I guess it went for development during that process. I had ran the engine from VS to create the project

elder falcon Feb 20, 2018, 2:40 PM

#

can be very confusing when you edit stuff in debug, then the editor loads old development binaries without telling you

lost linden Feb 20, 2018, 2:40 PM

I guess I was trying to cut corners that shouldn't be cut. You live, you learn

ah fuck, i thought i google searched this last night, but I must have been half asleep.

#

i dont recall doing this on my desktop, but i checked the box for ' "NuGet package manager"' in VS installer and it fixed it

#

does VS not use multiple cores when compiling unreal? Doesn't look like it.......

elder falcon Feb 22, 2018, 1:29 AM

#

vs doesn't compile unreal, ubt launches the compiler directly with as many processes as you have cores

warm fox Feb 22, 2018, 3:54 AM

#

Interesting, thank you for the correction.

#

I was watching my task manager during the compile and only saw one process running at <20% when I had 16 threads available. I checked the parallel build settings in VS and it was set to 16 already too.

elder falcon Feb 22, 2018, 4:08 AM

#

maybe it failed to detect the number of cores properly somehow?

#

build settings in vs have no effect since vs is not involved in the build process

#

you can set a multiplier in unreals buildconfiguration.xml to override how many things it does parallel

#

Any idea where I can get the log?

wraith crystal Feb 22, 2018, 4:56 PM

#

bit of a weirdo question, but here it goes... is UE4 really using the $HOME/.config/Epic directory as a lock for mutexes on Linux?

#

so in other words, is it using file locking for threads? I would find this very weird

#

the Windows version (WindowsCriticalSection.cpp) seems to be acquiring mutexes from the OS, using the Windows API CreateMutex(), which is okay

#

but the linux version... files? really?

#

(same goes for Mac)

elder falcon Feb 22, 2018, 5:29 PM

#

that seems to be a special thing for multi-process mutexes

#

the normal one is in pthreadcriticalsection.h

wraith crystal Feb 22, 2018, 5:32 PM

#

thanks; that means multi-process mutexes are using file system locks, correct?

elder falcon Feb 22, 2018, 5:32 PM

why

warm fox Feb 22, 2018, 10:52 PM

#

Is it possible to do headless compiling on windows/linux server? So far it seems like I have to start the editor and package a project before I can build from command line. I found someone else saying the same thing, that the manual intervention breaks their jenkins CI workflow.

small cobalt Feb 22, 2018, 10:52 PM

#

I dont have any issues with my Jenkins instance building from source and packaging.

warm fox Feb 22, 2018, 11:18 PM

#

Thanks, so you did not have to run the editor at all to get that to work? I'm talking about only compiling the engine and then running RunUAT. I can't run the editor in my cloud VM.

elder falcon Feb 22, 2018, 11:24 PM

#

you have to run the editor for cooking, but in cmd mode without gui

warm fox Feb 22, 2018, 11:26 PM

#

Thanks, I was trying with the commands here https://wiki.unrealengine.com/How_to_package_your_game_with_commands are they still valid for 4.18.3?

How to package your game with commands

it seems to be missing a few things

small cobalt Feb 22, 2018, 11:31 PM

I havent tried packaging or compiling for 4.18 but i cant imagine that the command line would need to change much

elder falcon Feb 22, 2018, 11:32 PM

#

the -ue4exe=UE4Editor-Cmd.exe is missing at least

#

are you trying to make a build on windows or linux ?

#

windows

#

i just tried to run it again and now i get a new error 😅

why is it using the engine folder as a base dir for the project? I put -project C:\gitlcones\test\test.uproject

elder falcon Feb 22, 2018, 11:42 PM

it should be -project="..."

#

I have a bunch of batch files for building/packaging my project, maybe they will help you

#

this one is in the engine folder so the other batch files know where the engine is

#


echo Registering Brickadia Unreal Engine dir as %~dp0%...
setx BRICKADIA_UNREAL_DIR %~dp0%
pause```

#

this one builds the editor modules to be able to package

#


if not exist "%BRICKADIA_UNREAL_DIR%" (
    echo Error: Brickadia Unreal Engine dir not registered. Run BrickadiaSetup.bat in engine root.
    pause
    exit
)

call "%BRICKADIA_UNREAL_DIR%Engine\Build\BatchFiles\Build.bat" BrickadiaEditor Win64 Development -project="%~dp0%Brickadia.uproject" -waitmutex
pause```

#

this one packages the game

#


if not exist "%BRICKADIA_UNREAL_DIR%" (
    echo Error: Brickadia Unreal Engine dir not registered. Run BrickadiaSetup.bat in engine root.
    pause
    exit

:: RunUAT messes with current dir, need a copy

#

Hi there, where I can enable stats counting from commandlet?

boreal orchid Feb 23, 2018, 1:43 PM

#

I guess I need to rephrase the question.
So I found

bool UEngine::HandleStatCommand( UWorld* World, FCommonViewportClient* ViewportClient, const TCHAR* Cmd, FOutputDevice& Ar )

on the 3437 line in UnrealEngine.cpp

But as we can see it doesn't toggle Stat when ViewportClient is nullptr

return ViewportClient ? (this->*(EngineStat.ToggleFunc))(World, ViewportClient, Temp) : false;

ViewportClient is nullptr because I tried to run it from Commandlet.

So how I can enable stat counting \ calculations for Level from commandlet?

slow crescent Feb 23, 2018, 1:58 PM

#

On the off chance that someone might know the solution to this:

I have a custom Blueprint class that needs to override UBlueprint::GatherDependencies. The problem is that some of the dependency blueprints might not be loaded at that time, and when I try to load them using LoadObject<UBlueprint>(...) I get a crash. This is because FBlueprintCompilationManager::NotifyBlueprintLoaded gets called, which modifies FBlueprintCompilationManagerImpl::QueuedRequests, which is already being looped over at that time.

So my question is, is there another way to report which blueprints should be loaded along with my custom blueprint, so that they're already loaded by the time the compilation (and subsequently UBlueprint::GatherDependencies) happens?

stable hemlock Feb 23, 2018, 3:22 PM

#

how does the compilation manager normally ensure all blueprint dependencies are actually loaded? the execution path of that does seem to assume the blueprints are already loaded

slow crescent Feb 23, 2018, 3:32 PM

#

Yeah, that's what I'm trying to find out at the moment. From what I can tell anything referenced by a blueprint is automatically loaded when that blueprint's package is loaded, and that list of references seems to be created when the blueprint/package gets saved. The criteria for this list of references seems to be that the object is a child to the package.

stable hemlock Feb 23, 2018, 3:35 PM

#

hmm is the requirement for your dependencies fully dynamic? if so that sounds like it would be tricky to work around, otherwise you could just add a hidden UProperty child or something just so its referenced

slow crescent Feb 23, 2018, 3:41 PM

#

If I understand you correctly I wouldn't say they have to be fully dynamic no. It's part of implementing a scripting language, and the dependencies would only get "resolved" when the custom blueprint gets compiled. I'll give the unused/hidden UProperty route a try and see how it goes.

stable hemlock Feb 23, 2018, 3:43 PM

#

is the goal to have scripted classes which can depend on blueprint classes which depend on scripted classes? sounds like something I want to do somewhen down the line but the circular dependency sounds kinda scary to me

slow crescent Feb 23, 2018, 3:47 PM

#

Yeah, that part actually seemed to work right out of the box, by simply reporting the blueprint class dependency through UBlueprint::GatherDependencies. I guess the BP compiler itself resolves the circular dependencies somehow.

shrewd thorn Feb 23, 2018, 6:07 PM

#

I would look at what some of the blueprint subclasses like WidgetBlueprint and AnimBlueprint do, maybe copy that. That code is complicated

maybe it doesn't keep track of which ini settings affect cooking, but since some can, it'll re-cook just to be sure?

Does anyone know if an upgrade of Recast is planned anytime in the near future? UE4 is currently using a version of Recast that was released 9 years ago, in 2008 if Recast-License.txt is to be trusted. The latest version of Recast, 1.5.1 was released in Feb 2016. Is an upgrade on the roadmap?

#

then I ran the same engine, but not the installed build, the "regular build"

made project files with it and shipped them

#

why does the installed build think the project files where made with a different version of the engine and ask to make a copy of the project?

i want to start reading the engine source code. Do you have any idea on which is the best point for starting reading it?

small cobalt Feb 28, 2018, 8:23 AM

#

@ripe drum You would kind of need an interest in an particular area, the Engine is an extremely large and complex piece of software. What are you more interested in?

ripe drum Feb 28, 2018, 8:27 AM

#

that's a good point, but i want to read it because i want to be better and faster at reading code. And also as an exercise for becoming a better programmer by learning some cpp solution, best practice etc, so... or the most elegant code of the engine, or something related to graphics or physics should be good.

small cobalt Feb 28, 2018, 8:42 AM

#

@ripe drum In that case just start with LaunchEngineLoop

#

For example.

#

https://github.com/EpicGames/UnrealEngine/blob/dbced2dd59f9f5dfef1d7786fd67ad2970adf95f/Engine/Source/Runtime/Launch/Private/LaunchEngineLoop.cpp#L1965

@gray glade thx for the reply I did manage to make it work by changing build setting from development editpr to shipping and rebuild the engine

That's not really a solution. :/

elder falcon Mar 1, 2018, 12:03 AM

can you even build the engine in shipping mode?

gray glade Mar 1, 2018, 12:05 AM

What do you mean? The editor, no, but the engine? Most def.

That's how a blueprint-only project works.

interesting

winter citrus Mar 1, 2018, 12:06 AM

Hahaha really ? I have followed the unreal instructions
1 - I downloaded the git source
2 - run the setup downloaded all files
3 - run generate source project
4 - build the shadercompiler
5 - build the UE4
6 - when I try to run the engine I get that error

gray glade Mar 1, 2018, 12:06 AM

#

For whatever reason you seem to be missing libogg

#

Why? I don't know. But maybe try running the setup script again?

#

Building shipping isn't a solution because you don't want to only build a shipping config.

winter citrus Mar 1, 2018, 12:07 AM

#

Yepp ur right :/ I have tried to open a c++ project the engine didn't run only blue print

#

Project can open the engine

#

Wired I will try to run. The setup again

#

As a curiosity what is the difference between the development editor build and the shipping build ?

signal leaf Mar 1, 2018, 12:15 AM

#

When using the Engine from source (for dedicated server reasons) how often do you have to build the engine? These 40min - 1.2 hour wait times are unbearable

steady flint Mar 1, 2018, 12:25 AM

#

only when you upgrade it or make changes to it.

#

also for a dedicated server do you need the engine source?

elder falcon Mar 1, 2018, 12:26 AM

#

they don't include a prebuilt server exe for the launcher version

signal leaf Mar 1, 2018, 12:26 AM

#

@steady flint From what I am reading yes

#

Only when I upgrade the engine or make physical changes to the engine code right?

steady flint Mar 1, 2018, 12:27 AM

#

couldn't you just add a targetServer.target.cs?

#

mark it as a server and package out to server?

elder falcon Mar 1, 2018, 12:27 AM

#

that's what you do but you need the engine source in order to build the server exe

steady flint Mar 1, 2018, 12:28 AM

#

ahh hmm

elder falcon Mar 1, 2018, 12:28 AM

#

for some reason a dedicated server requires a completely different exe

#

I'd prefer just having a -server switch on the normal one

steady flint Mar 1, 2018, 12:28 AM

#

yeah so any time you make changes to the code or upgrade engines or other wise effect what the dlls should be

#

so not often and you can use iterative compile

elder falcon Mar 1, 2018, 12:29 AM

#

also every time you update vs or accidently click rebuild :D

signal leaf Mar 1, 2018, 12:30 AM

#

What about compiling the server EXE

#

How often does that need to happen, cuz that too also takes a freaking long time

elder falcon Mar 1, 2018, 12:30 AM

#

it should only take long the very first time

#

from then on the engine modules are already built, so only your changes need to be built again

signal leaf Mar 1, 2018, 12:31 AM

#

Seems to be taking a while anytime I make some changes and want to recompile the server to test said changes. Like 40mins still

elder falcon Mar 1, 2018, 12:31 AM

#

that's definitely not right, it should be more like 30 seconds to 1 minute max

signal leaf Mar 1, 2018, 12:31 AM

#

I have a QuadCore i7 3.5 Ghz

elder falcon Mar 1, 2018, 12:32 AM

#

unless you have ltcg enabled in build.cs and are making a shipping build

#

then it takes a while longer

signal leaf Mar 1, 2018, 12:36 AM

#

development server

elder falcon Mar 1, 2018, 12:41 AM

building a dev server for the very first time takes 5 minutes for me

changing something and building it again takes 24 seconds

if a change is taking you 40 minutes something is very wrong :v

So any ideas on why when I build and launch UE4 it always says, "These projects are out of date: " and to rebuild them. Even after I just did that 5-10 mins ago. All I did was create a new Project.

Hey, is there a way to change the target of UE to vs17 instead of vs15? I have changed the accessor and rebuild my project, and even tried creating a new project but it keeps trying to use vs15 which I don't have installed

elder falcon Mar 2, 2018, 4:21 AM

#

if the project setting doesn't work, you can put this in BuildConfiguration.xml to make it always use vs 2017

#

Hey, people!

I have a question regarding building the game I'm working on with a new plugin. Specifically, the RedShell plugin (https://docs.redshell.io/docs/unreal-engine-sdk-quick-start). I've been following the docs for it and it seems to be working perfectly, save for one little hitch. When building the standalone game, the DLL needs to be copied into the Binaries directory along with the executable, which I believe is not ideal. This is not the case when building and playing in the editor, and with the DLL in the Binaries dir everything works smoothly. The error message I get when trying to start the game without the DLL is:

The code execution cannot proceed because RedShell.dll was not found. Reinstalling the program may fix this problem.

When running it in debug mode from VS, the error says that a dependent DLL was not found, and the debugger shuts down before it hits any actual code.

I've been trying to get this fixed for days, but I'm really new to Unreal and I really do not know what is going on here. Any chance anyone has a clue? Any help would be most appreciated.

For reference, the version of Unreal is a customised version of 4.15.

gloomy hamlet Mar 2, 2018, 12:09 PM

@thick sentinel Those settings are only for the IDE association. UE4 still isn't compatible with the VS2017 toolchain, so you need to at least have the 2015 build tools installed regardless.

low dust Mar 2, 2018, 12:17 PM

#

if you change build conf, it probably has to recompile most of the things again

#

oh crap

slow crescent Mar 2, 2018, 2:16 PM

#

I've been compiling both our game and UE4 with VS2017 for a couple of months now (both 4.17 and 4.18), and I don't have the VS2015 toolchain installed. Haven't had any real issues as far as I can remember.

gloomy hamlet Mar 2, 2018, 4:30 PM

#

Compiling is done by UBT, not VS directly. Previously at least, UBT hard coded to the 2015 compiler even if you were using 2017 project files.

#

It's possible that's changed recently, though I didn't hear anything.

#

@half arrow Looks like the plugin is missing a runtime dependency entry for the dll.

#

Try replacing the existing line PublicDelayLoadDlls.Add(...) with PublicDelayLoadDlls.Add("RedShell.dll"); RuntimeDependencies.Add(Path.Combine(redshellDir, "bin", "x64", "RedShell.dll"), StagedFileType.NonUFS);

#

And accordingly for Win32.

seems they opt for 2015 if it's installed, otherwise use 2017

gloomy hamlet Mar 2, 2018, 4:45 PM

#

Interesting. So I wonder what the xml file setting is for forcing 2017 compiler.

#

Weird that they sneaked this in at some point, seemingly without announcing that it's now possible to use latest toolchain.

slow crescent Mar 2, 2018, 4:55 PM

#

the code seems to suggest they use the <VCProjectFileGenerator><Version> setting unless there's a compiler explicitly set (through commandline I assume)

Well you can run from a cmd prompt, that should show what the issue is before the window closes

If it gets far enough it does save a log but you're probably failing before it gets that far

@gloomy hamlet UE4 works with the 2017 toolchain for a long time already

#

I'm still on 4.15 and that also works fine with 2017 (I don't have 2015 installed)

#

and 4.15 is more than a year old

gloomy hamlet Mar 2, 2018, 8:52 PM

#

Well I wish I'd known that. I removed 2015 at some point because I just assumed 2017 was fully supported and got all sorts of issues complaining about missing 2015 toolchain. Ended up reinstalling the build tools.

#

I guess some leftover registry entries confused UE4 in some way, and that made me assume 2015 was still needed...

I didn't really convey my issue very well, sorry. When I try open a cpp file inside of UE it opens a new instance of VS (if one is already open) and does not actually load the file in the project. When I tried what Zeblote said It would open the cpp file but still create a new instance. Since then I have tried installing VS15 and the problem was still there ( I have since uninstalled VS15 ). I then tried a project in UE4.17 and the problem was gone, So for me the issue only appears in UE4.18. I have tried making a new UE4.18 project and it still exists. When in UE4.18 if I try to compile it says "LogVSAccessor: Warning: Couldn't access Visual Studio", This does not occur in UE4.17.

#

I was just thinking, when I was setting up stuff on my "new" computer I may have installed UE4.18 before installing VS, but because I was having issues opening my UE4.17 project with just UE4.18 I installed UE4.17, after VS was installed unlike UE4.18 which installed before, Could this have broken something with the 4.18 install of UE?

elder falcon Mar 3, 2018, 5:23 AM

when in widget reflector, is there any way to find out what source file or even which line is spawning this SEditableText? https://i.gyazo.com/312ec7012c1244461cd5fe6a5f17c800.png

half arrow Mar 3, 2018, 3:16 PM

#

@gloomy hamlet Thanks for the suggestion! You mean in RedShell.build.cs, right? (I mean, that's the only place the docs specify DelayLoadDLLs) Anyway, I tried it, but sadly: No dice. Same error as before, I'm afraid.

gloomy hamlet Mar 3, 2018, 3:22 PM

#

Yep that's where I meant. This stuff is very fiddly due to Windows' dll search path system, and UE4 not letting you deploy files to specific locations

#

Looking at the code, the plugin has been very hard coded - it seems to assume that it's located at project level (as opposed to engine), and at [ProjectFolder]/Plugins/RedShellPlugin.

#

Is that the case in your setup?

half arrow Mar 3, 2018, 3:43 PM

#

Well no, not quite. It's located in the engine folder, under Plugins/Runtime, but I have updated the source code in RedShell.cpp and in the Build.cs file to match its new path.

#

Would there be anywhere else where I might need to do it?

gloomy hamlet Mar 3, 2018, 3:45 PM

#

Shouldn't be.

#

Do you use any types/functions from the redshell dll directly in your own code?

#

It sounds like something is triggering the dll load statically, which overrides the delay loading and so it can't find it in the default search path.

stable hemlock Mar 3, 2018, 3:53 PM

#

ugh..

#

while localizing the game, can't translate multiline original text into multiline text. no possibility to shift+enter

#

was thinking it's an SEditableTextBox instead of SMultiLineEditableTextBox in there and a quick replace would fix it

#

but it's some kind of generic SPropertyTable in which you just feed any simple class (in this case UTranslationUnit) and it creates these columns and rows automatically

#

and for an FString it always creates an SEditableTextBox

#

can't even find where exactly it does that, it's so complicated

gloomy hamlet Mar 3, 2018, 3:58 PM

#

Not sure I follow exactly, but you know you can add Meta = (Multiline) to the UPROPERTY macro?

stable hemlock Mar 3, 2018, 3:58 PM

#

that's what i just thought. am trying it. it's my last hope

half arrow Mar 3, 2018, 4:04 PM

#

@gloomy hamlet , As per the docs, I call out to their services in a startup file (MyGame.cpp), around the time when everything else gets initialised, as close to the end as I could fit. I use no types from there, but I do use some of their functions. Don't know if this is useful, but I'm pretty confident that I had the same issue when the plugin was part of the project too. Back then, as now, it could be resolved by placing the dll next to the executable. I suppose the root of the issue here is that UE can't find the DLL or the folder it's in for whatever reason.

signal leaf Mar 3, 2018, 4:04 PM

#

Anyone know if packaging a project takes longer the first time and should take less time for later packages?

stable hemlock Mar 3, 2018, 4:05 PM

#

so, no, Multiline didn't help...

#

oh. actually it did in a way. i can now paste multiline text into it, but shift+enter still doesn't work

gloomy hamlet Mar 3, 2018, 4:09 PM

#

Did you try Ctrl+Enter maybe? Can't remember, but I know I've used that Meta before and it worked fine.

#

@signal leaf Yes, it will cache cooked assets.

#

@kind root The delay load approach is intended to get around that requirement so plugins can be easily deployed. It basically tells Windows not to load the dll at startup, but to delay until it's needed. Then the plugin explicitly loads it from the path it knows it's located, before Windows tries to load it from default paths and fails.

signal leaf Mar 3, 2018, 4:12 PM

#

@gloomy hamlet Sweet, ye it seems to be significantly faster this second time, awesome!

#

Thank you so much ❤

gloomy hamlet Mar 3, 2018, 4:13 PM

#

No worries.

#

And sorry for wrong tag, Thomas.

#

@kind root But it seems like that's not working, and one reason would be if you use something from the dll before the plugin module startup code runs. Realistically that should only happen if you have a global/static variable of a type from the dll, though.

#

FFS, okay it wasn't me, Discord tagging is just broken...

stable hemlock Mar 3, 2018, 4:24 PM

#

ctrl+enter doesn't work either. it works in other places like dataassets, but not in here. something must be handling "enter" from shift+enter before it has the chance to go to next line.

#

found the code that defines it:

📎 3e2ed9f07d6729428fd4fbd15e5d28bb.png

#

should be fine, but what actually happens when you do shift+enter, it commits text and selects next row

#

going to change shift to ctrl to see if that changes anything

#

no, exactly the same behavior

half arrow Mar 3, 2018, 6:41 PM

#

@gloomy hamlet Hah, oh, sorry for having a confusing username. But thanks for all your help. The only times I use anything from it is when calling the Init and LogEvent functions as defined in the docs, though, so I don't think there's anything static about it that way. The code is wrapped in some #ifdefs, but they don't use anything related to the plugin itself, so I doubt that's the cause of it.

gloomy hamlet Mar 3, 2018, 7:04 PM

#

Yeah, not sure then. You're talking about a packaged build, correct? If you have tried stepping into it (F10) with the debugger, and you get the error without any code running at all, than that definitely means the dll isn't being delay loaded for one reason or another.

#

Can only suggest double checking the delay-load line in the build.cs (try with just filename as I posted, instead of full path).

half arrow Mar 4, 2018, 11:30 AM

#

Err, not sure about the packaged build, to be honest. I normally do tools, but was asked to integrate this plugin, so I'm sort of at a loss for this. As for the delay-load line, I already did try with just the filename, and it made no difference, though maybe if I leave out the RuntimeDependency ..? I'll give it a go tomorrow. Thanks again for all your help, though.

gloomy hamlet Mar 4, 2018, 11:35 AM

#

The runtime dependency is required for the dll to be copied when packaging a project. You mentioned building 'standalone' - how are you building the project that leads to having this error when running?

half arrow Mar 4, 2018, 6:19 PM

#

Right. That makes sense, though it's strange that they have not included that line in their source files, then. Regarding how I'm building, I'm honestly not sure. As I mentioned, I don't usually do Unreal, so I'm just following the company's internal documentation. All I know is that it has multiple configurations for different kinds of builds based on branch and whether it's server/client, etc. Anyway, If I can't get it to work I can go and grab one of the people who usually deal with the game proper and I'm sure they can help me. I just wanted to make sure I'd given it a proper go before I go running for help, hah.

#

Hey, @gloomy hamlet , just wanted to thank you again for all your help over the weekend. I managed to get past the missing DLL issue today, and I'm a bit ashamed to admit that it seems to be due to finally changing the Win32 section of the plugin as well. I had originally neglected this, seeing as we don't build for 32 bit, but it seems to have been important nonetheless. Apologies for my thickheadedness. Anyway, I managed to step into it now, and sure, I'm encountering some exceptions, but it's progress at least! Whether it's listed with the full path or not in the PublicDelayLoadDLLs doesn't seem to matter for this, though, so I'm wondering what difference it's supposed to make? In fact, even without the RuntimeDependency it appears to be working now. Well, 'working' as in starting up without complaining about the DLL.

gloomy hamlet Mar 5, 2018, 2:27 PM

#

@half arrow Glad you made progress. Yeah the RuntimeDependency is only relevant for the packaging process, which perhaps you're not doing.

#

With delay load path, I just know that filename is sufficient. Full path may also work, but I don't know if that may cause it to break when the project is installed to a different location.

half arrow Mar 5, 2018, 2:33 PM

#

Ah, okay, that makes sense about the filename / full path. I guess keeping it as relative as possible is always a good idea. The issue now, however, is an unhandled exception in the delay load process (delayhlp.cpp) where it can't find the Module. I'm guessing I've made a mistake somewhere, so I'll go and double check everything. Using the debugger, I can step into the exception, but it's mostly long hex values and intricate strings that I'm not really sure what mean, so not entirely sure how best to work it. Do you have any idea?

gloomy hamlet Mar 5, 2018, 3:08 PM

#

Has execution reached the part in the part in RedShellPlugin.cpp that calls FPlatformProcess::GetDllHandle?

#

Thing is I still don't know the process you're following for building/running, so hard to diagnose the issue.

stable hemlock Mar 5, 2018, 5:20 PM

#

https://github.com/EpicGames/UnrealEngine/blob/master/Engine/Source/Editor/KismetCompiler/Private/KismetCompiler.cpp#L245 isn't this the same as ClassAddReferencedObjects = UClass::AddReferencedObjects; since that function should be a static function unless there is another generated one somewhere? feels like that logic should be ClassAddReferencedObjects = ParentClass->ClassAddReferencedObjects;

half arrow Mar 6, 2018, 8:07 AM

#

Hmm, actually, that's a good point. It never reaches that part of the code that during execution; it seems the StartupModule() function is completely untouched.

I'm trying to dig up info on custom shading models. In some of the 2+year old threads, some people are referencing usf files that don't appear to exist in 4.18:
DeferredShadingCommon.usf
DeferredLightingCommon.usf

Might these have been merged in *Shared/Common.usfs?

They change the extension file to ush instead of usf

@strange urchin Awesome thanks a lot for the confirmation. I found the ushs actually, but some of the referenced function names in those older threads must've changed too, because I can't find them in the corresponding ush.

@half arrow If you want to post the log output I can take a quick look. But if you're saying you can step into the program without issue (so it's not failing at the point the OS loads the .exe), but you get an error about the .dll before the plugin module starts up, that sounds pretty bizarre.

half arrow Mar 6, 2018, 12:48 PM

#

Thanks for the offer, but I don't think I can do that. I'm not entirely sure what can and cannot be shared with the public, so I'd rather err on the side of caution there. But yes, I can step into the program just fine, the .exe starts up no problem, and then when the RedShell functions get called it crashes. Not sure what the deal is, and it might be a bit bizarre, but I'll figure it out eventually 😉

I'd like to hear how anyone manages their build of the engine from source. What branch of the engine do you typically work with?(my expectation is release) Do you do git pull periodically? Can the pull be automated?

gray glade Mar 6, 2018, 9:27 PM

#

Yes, release.
Define periodically?
Yes, of course it can.

#

I'm of the mind you should upgrade engine versions regularly as they release - don't wait until it's a nightmare to upgrade, but don't upgrade hastily and end up stuck with some particular engine bug that's critical for your game - merge the newer engine version in a separate branch and test that out for a bit. Assets are not backwards compatible - once saved in a newer engine version, you can't open it in an older engine version.
