Let's say I have a freshly cloned Unreal Engine source, and I want to build my game. What is the least amount of things I need to do on UE4 in order to build my game? I guess Setup.bat only? Or do I need to build the editor?

solar sequoia May 15, 2019, 8:45 AM

#

@lost glen You run setup.bat in the source, then generateprojectfiles.bat, then you open the sln solution and build the engine under development editor

lost glen May 15, 2019, 8:58 AM

#

@solar sequoia thx, but that's not what I need. I am working on a build server image for our game and I wanted to know the minimum number of actions that need to happen for you to build your game

#

(in the fastest way)

pine flume May 15, 2019, 11:27 AM

#

@lost glen the Editor needs to be built in order to build and package projects, since the UE4Editor executable is invoked to run the commandlet that cooks content. If you're preparing a build image for CI use then you will need the following as a minimum:

Setup.bat (ensures all Engine dependencies are downloaded)
GenerateProjectFiles.bat (ensures UnrealBuildTool is built)
Either invoke UBT to build the UE4Editor, ShaderCompileWorker and UnrealPak targets, or use RunUAT to create an Installed Build of the Engine (https://docs.unrealengine.com/en-us/Programming/Deployment/UsinganInstalledBuild)

An Installed Build will take longer to create due to the overheads of generating the DDC for all Engine content, but once the DDC is generated it will significantly speed up the process of packaging games, since only the game's unique content will need to be cooked.

Thx!!!

#

Exactly what I was looking for

pine flume May 15, 2019, 11:31 AM

#

If you're unfamiliar with invoking UBT or RunUAT from the command-line, the examples in these Dockerfiles may also be of help:

Invoking UBT: https://github.com/adamrehn/ue4-docker/blob/v0.0.31/ue4docker/dockerfiles/ue4-engine/windows/Dockerfile

I know your site by heart @pine flume

#

I even started building this based on your docker work but eventually settled for custom AMIs

#

The super huge docker images were a deal breaker for me.

pine flume May 15, 2019, 11:34 AM

#

Yeah, the Windows ones in particular are nightmarishly huge, and Docker isn't really designed to cope with building image layers that big. The filesystem commits take forever and Docker uses hundreds of gigabytes of scratch space during the build. It's not so bad if you're using prebuilt images, but building them from source is a royal pain.

#

Fortunately the new GitHub Package Registry might finally provide a way to share prebuilt images with other members of the UE4 community that complies with the EULA, since it looks like it'll be possible to associate images with a fork of the UnrealEngine repo and have them inherit the access permissions from the fork.

I'm hopeful

even if we have a custom version of ue4 and can't do that

lost glen May 15, 2019, 12:02 PM

#

@pine flume while we're at it do you know if there's a UAT script that I can use to export an installed build to a zip file? I know how to do it from scratch but not if I've already built it.

pine flume May 15, 2019, 12:11 PM

#

Not that I'm aware of, no. It should be as simple as zipping up the root directory though, since I don't believe there are any symbolic links inside the directory tree.

#

It'll be under LocalBuilds/Engine/Windows.

bright olive May 15, 2019, 5:36 PM

#

when you change a property on a placed actor's component in editor, what all needs to be done to make sure it gets saved? the SteamAudio plugin is setting a plugin identifier thing on audio components when you bake (UAudioComponent::AudioComponentUserID), but it gets reset the next time I restart the editor, even if I save map afterwards.

I tried adding a call to AudioComponent->MarkPackageDirty(), but it still seems to happen, is anything needed beyond that?

So i SUCK at CPP, but anyone know why i can't see the CPP files inside UE4? they are in the VS Editor

granite dust May 16, 2019, 1:28 AM

That is how it is. You can see that they exist from within the editor by going up a few folders in the explorer thing

small cobalt May 16, 2019, 1:30 AM

@bleak heath Cpp files are hidden by default in the editor content browser.

You have to enable them

I might have a stupid question that there is no nice answer to... I have a PR waiting since January to be looked at... it is marked for review... still mergable(because nobody touches that part of the engine code). I am pretty sure it is lost in the history. Is there a way to "ping" it up? In a nice non-obtrusive way, as it is a special case that possibly nobody cares about 😃

Edit for those interested. #5477

the issue is how to make it "properly"

and then it does ti for you

#

by copying the values of the primary actor tick into the aggregate

elder falcon May 21, 2019, 4:56 PM

#

it needs to support the dependencies somehow

as long as they're not different for multiple instances

#

also wtf too many videos

its gonna take weeks to watch them all

brisk silo May 21, 2019, 5:00 PM

#

no, no dependencies

#

if you enable tick batching, dependencies arent a thing

#

or the dependency is on a per-class base (thats doable)

#

but the most obvious thing is that this is an automatic speedup with engine components

#

such as particle sys component

so why is it not a thing?

@brisk silo how will auto aggregation handle the fact that tick is virtual function?

Some temple magic and special non virtual tick for batching?

brisk silo May 22, 2019, 4:33 PM

@thick storm not even needed

the thing is that the vtable and virtual function code will be on the L1 cache

Thank you! 😃

So my most comfortable place is plugins - I'm still relatively new (only a couple months) into both C++ and UE4.

Obviously, I should get the engine source, make my modification to the current layouts, but honestly, I just have a fear of contributing inherently stupid code 😛

From what I've seen your code is basically a command + the callback to execute?

slim schooner May 26, 2019, 1:56 AM

Effectively 😃

spiral mortar May 26, 2019, 1:57 AM

Then all you need to do is add that command next to the engine reset layout one

And the function next to the one doing the reset

slim schooner May 26, 2019, 1:57 AM

#

Awesome ^_^

#

There's a feature I'm adding at the moment, that is a little more than just the import/export/recent functionality,

#

which I'm skeptical would be accepted in the pull request given that it basically is a tab window that allows for 'quicker switching',

spiral mortar May 26, 2019, 2:00 AM

🤔

slim schooner May 26, 2019, 2:00 AM

#

The reason I'm skeptical is that unfortunately, slate requires the engine restart in order to actually load in the new layout - I've not been able to find a way of having UE4 regenerate all of slate without an engine restart.

spiral mortar May 26, 2019, 2:01 AM

#

Yeah I've always been surprised by that

slim schooner May 26, 2019, 2:01 AM

#

my thought with the concept is similar to Modo/Blender, etc. You can switch up layouts on click.

#

I had some coder friends at my work check it out - everything in slate is based on RootWindow, and trying to override or regenerate this seems a little impossible without serious rewriting.

spiral mortar May 26, 2019, 2:02 AM

But I mean

#

It's just some positions

#

voxelthonk

#

I'll have a look tomorrow

slim schooner May 26, 2019, 2:03 AM

#

For sure, it's basically telling each tab to regenerate based on the given layout.ini - it does seem simple in theory, but then, with Unreal - nothings ever simple in practice... ^^"

#

That would be awesome, phy :3 ❤

Anyway, tomorrow I'll clean up what I've got and start looking at adding it to a fork, this has been a fun first qof project :3

slim schooner May 26, 2019, 1:07 PM

#

I mean I could probably parse the ini files when I've loaded a new one in, but I would still have to get slate across the editor to update the vals.

Dedicated servers don't render at all

#

They also generally don't generate particles and any other cosmetic actors that don't influence gameplay

#

Oh I've never done that

#

My dedicated servers run on Linux and I haven't ported the game itself to Linux, so it makes sense for me

#

So if you run with -server it takes the dedicated server path? And NetMode reports as Dedicated?

elder falcon Jun 3, 2019, 5:43 PM

the -server is only usable in editor builds

well a packaged build is definitely not an editor one

you can't pass -server to a packaged build

elder falcon Jun 5, 2019, 3:33 PM

#

it looks like epic has started merging all the branches to master 🤔

#

maybe soon there will be the chaos one

brisk silo Jun 5, 2019, 4:44 PM

#

@elder falcon nothing out of the ordinary on the merges

#

tho im definitely like "where is chaos dammit"

Can I safely delete the Engine source code after building from source? (If I'm sure I won't be making changes to the engine afterwards?)

#

Trying to recover some space

celest viper Jun 6, 2019, 2:04 AM

#

You could, I dont know why you ever would though. The source code itself is pretty minor. Did you take all the example games and content as well?

stable hemlock Jun 6, 2019, 2:05 AM

#

Oh hell, I really hope I didn't take the example games

#

But my Engine\Source dir is nearly 20GB, which is a lot for me

celest viper Jun 6, 2019, 2:07 AM

#

hmmm nah thats fair, Im surely only thinking about the code files, but once youve built youll end up with things Intermediates, PDBs, etc

stable hemlock Jun 6, 2019, 2:07 AM

#

Will plugins still compile if I delete the Engine\Source directory? (It seems the Engine\Intermediate directory is required)

celest viper Jun 6, 2019, 2:08 AM

#

I wouldnt expect it. If youre still planning on building your game or doing work.... trying to pull my directory up here

#

so yeah Ill say its a bit odd if just your Source dir is 20GB? Mine is around 5.2GB locally (though Ive got 4.21.1 locally)

stable hemlock Jun 6, 2019, 2:12 AM

#

Wow, really? I wonder what the heck I did

#

I made like 20 small edits to the vanilla 4.22.2 and then cloned my branch with Git

#

Yeah, on both my laptop and desktop, it's 18.7GB

celest viper Jun 6, 2019, 2:15 AM

#

huh....yeah to be fair I dont pull down from Git, and I barely pull the engine down here at home anyways heh.

simple shell Jun 6, 2019, 10:51 AM

#

hello.. uhm sry if this fits more in cpp... but i think it's more related to the engine source .. so i will ask it here ^^
I was setup the new build server with ue4.22 source installation and tested one of my projects to build a linux dedicated server. (which worked with the old build server and 4.20/clang-5)
Now i always get missing libs from the source installation.

12:05:13     ld.lld.exe: error: unable to find library -lembree3.so
12:05:13     ld.lld.exe: error: unable to find library -ltbb.so
12:05:13     ld.lld.exe: error: unable to find library -ltbbmalloc.so

The compile for linux works without any problems... only linking failed because of the missing libs ^^
Checked the third party folder and it was always only Win and Mac builded. (But this was missing on the old server too, maybe tbbmalloc is a new requirement for 4.22?)
using the v13_clang-7.0.1 toolchain for cross compiling.
As i remembered i didn't miss a step or a "build XY" in visual studio... (tested it again with build all ^^)
hope someone has some hints for me :/ (and thanks for your time ^^)

shell lily Jun 6, 2019, 10:03 PM

#

Can you just apt-get libtbbdev?

simple shell Jun 6, 2019, 10:09 PM

#

it's on windows... not native

#

currently i'm working with two buildsystems... for linux now with a native linux server and own ue4 source installation.
this works for now... but cross compiling failed all the time ;)

https://github.com/EpicGames/UnrealEngine/commit/ede40a0aa3f7e945e0b136d08a70f2c698a78d16 only took 4 years to get rid of that dumb requirement again

br_egg the bot added ispc files as binary dependencies so I can't open them on my phone

finally

downloadin

brisk silo Jun 9, 2019, 9:42 AM

#

@elder falcon i dont see any ispc

#

alright im a dumbass, github defaulted to the release branch, not master

brisk silo Jun 9, 2019, 10:40 AM

#

@elder falcon there is indeed ispc code now

#

but only a couple things

thick storm Jun 9, 2019, 10:41 AM

#

that's probabaly because entire chaos implementation is currently in limbo

#

between physx and new interfaces

brisk silo Jun 9, 2019, 10:41 AM

#

it just got megamerged

thick storm Jun 9, 2019, 10:42 AM

#

i know

brisk silo Jun 9, 2019, 10:42 AM

#

tons of things on it now

thick storm Jun 9, 2019, 10:42 AM

#

there are new Modules PhysxCore and PhysicsSQ

brisk silo Jun 9, 2019, 10:42 AM

#

btw, to make ispc work, you just add .ispc files to the build folder

thick storm Jun 9, 2019, 10:42 AM

#

PhysicsCore*

brisk silo Jun 9, 2019, 10:42 AM

#

and it will generate a file.ispc.generated.h

#

looks useful, i wonder if i could make my spaceship experiment run on that

thick storm Jun 9, 2019, 10:43 AM

#

probabaly

#

but you are still going to be locked on transform update )(;

#

either way to hoped for more chaos drop

brisk silo Jun 9, 2019, 10:44 AM

#

📎 unknown.png

#

this is how they do it

#

@thick storm dont you remember i found a way to bypass the transform update enterely?

thick storm Jun 9, 2019, 10:44 AM

#

it mainly seems about better destrruction integration

brisk silo Jun 9, 2019, 10:44 AM

#

by setting ComponentToWorld directly, calc bounds, and then mark as needs render update

thick storm Jun 9, 2019, 10:44 AM

#

and PhysX <=> chaos interop

brisk silo Jun 9, 2019, 10:45 AM

#

they barely have any ispc stuff

#

just like a couple files

#

with a couple functions

#

and a header with vector + matrix

thick storm Jun 9, 2019, 10:45 AM

#

oh since you are on master..

#

does intellisense works for you ?

brisk silo Jun 9, 2019, 10:45 AM

#

yes

#

but ispc confuses it

thick storm Jun 9, 2019, 10:46 AM

#

It seems totally broken after update on VS2019

brisk silo Jun 9, 2019, 10:46 AM

#

                    (ispc::FVector&)Box->Min(),
                    (ispc::FVector&)Box->Max(),
                    (ispc::FTransform&)SampleToObjectTM,
                    (ispc::FVector*)&SampleParticles.XView()[0],
                    DeepestParticle,
                    AvgConstraint.Phi,
                    NumParticles);```

#

those two seem to be the use

#

so basically, reah. You add a ispc file to the code, with your functions, and unreal generates the namespaced function and links it for you

#

the casting tho...

thick storm Jun 9, 2019, 10:47 AM

#

you nevre know if it goins to be static

#

or reinterpret -;-

brisk silo Jun 9, 2019, 10:47 AM

#

📎 unknown.png

#

3 ispc in the entire engine

#

one of the uses is to generate a bounding box out of smaller bounding boxes

#

btw, the smaller bounding boxes can be transformed

#

makes sense, this is the root of several accel structures

wise cape Jun 9, 2019, 11:59 AM

Hey ya'll ^^"

#

Wondering if anyone can help me bind a delegate.

#

SAssetView.h

#

Not sure how to get access to it, but it appears the be the Content Browser Module. Alternatively, looking for a place to hook into when an asset has been named/renamed.

wise cape Jun 9, 2019, 12:45 PM

#

Figured it out 😄 -

AssetRegistryModule.Get().OnAssetRenamed().AddRaw(this, &FMyModule::OnNewAssetRenamed);

astral sapphire Jun 9, 2019, 11:22 PM

Is WidgetReflector source links still broken?

elder falcon Jun 9, 2019, 11:32 PM

elder falcon Jun 10, 2019, 5:26 PM

#

use for what?

stable hemlock Jun 10, 2019, 5:29 PM

#

Using it in unreal engine

#

Using it in unreal engine

#

elder falcon Jun 10, 2019, 5:31 PM

#

no

stable hemlock Jun 10, 2019, 5:31 PM

#

you sure that you can't?

elder falcon Jun 10, 2019, 5:32 PM

#

cooked content is for packaged games, not the editor

stable hemlock Jun 10, 2019, 5:32 PM

#

you can extract meshes animations sounds etc too

#

and use them again

#

But I can't do it with umap for any reason

elder falcon Jun 10, 2019, 5:33 PM

#

what's the reason for doing this

stable hemlock Jun 10, 2019, 5:33 PM

#

lost my old project

#

and just got the build

whole mauve Jun 10, 2019, 5:48 PM

#

is there some kind of notification I can listen for when a specific UObject type gets cooked?

#

the type is my own from a runtime plug-in I wrote

#

aha UObject::CookAdditionalFiles()

elder falcon Jun 10, 2019, 6:04 PM

#

I'd just look at some existing asset type that cooks stuff and how they do it

wise cape Jun 10, 2019, 8:37 PM

#

Anyone know how to include ContentBrowserUtils.h?

#

From what I'm redaing, I should have UnrealEd in my dependencies, which I do - still can't get it to comple.

shell lily Jun 10, 2019, 10:16 PM

#

Your Module type has to be Editor I’m pretty sure

#

I don’t think you can put that in a Runtime module

#

So if it’s in your game project you have to make a second module that’s Editor

whole mauve Jun 10, 2019, 10:43 PM

#

is there a standardised way to get the output dir when cooking content?

#

I have some independent files I need to write out somewhere, so something like Saved/Cooked/MyPlugin, but I cannot for the life of me figure out how to get that path

#

it's different depending on how I start the cooker

wise cape Jun 11, 2019, 12:02 AM

#

@shell lily Seems to have cleared the include issue, however I still get

error LNK2019: unresolved external symbol "bool __cdecl ContentBrowserUtils::IsValidObjectPathForCreate(class FString const &,class FText &,bool)" (?IsValidObjectPathForCreate@ContentBrowserUtils@@YA_NAEBVFString@@AEAVFText@@_N@Z) referenced in function "public: virtual void __cdecl FStyleGuideStandardModule::OnNewAssetAdded(struct FAssetData const &)" (?OnNewAssetAdded@FStyleGuideStandardModule@@UEAAXAEBUFAssetData@@@Z)

elder falcon Jun 11, 2019, 2:43 AM

try setting it in BuildConfiguration

astral sapphire Jun 11, 2019, 2:47 AM

yeah, i'd prefer to exclude Hololens at all, i wish i knew how

#

also, how BuildConfiguration related?

#

installing vc++ 2017 pipeline didn't help as well

it seems -CurrentPlatform can bypass that error...but...no Win64 in targets then

astral sapphire Jun 11, 2019, 3:21 AM

hmm, looks like "-2019 -Platforms=Win64" did the trick

dusky zinc Jun 11, 2019, 3:58 AM

#

@wise cape something changed between engine versions

#

It's for a too shader model

wise cape Jun 11, 2019, 8:39 AM

#

EyeIndex implies that it's VR, or part of the model was written to support it

#

Honestly I'm going on a whim though - shading models aren't something I've written yet.

#

Does anyone knows how GenerateProjectFiles keys work?

#

like what the priority order they have

astral sapphire Jun 11, 2019, 7:23 PM

#

BTW "-2019 -Platforms=Win64" did not work as well, it indeed generated the x64 project, but w/o Editor target. It can compile it, but can't run the debug.

#

Is BlankProgram something new? I haven't noticed it before.

I have a really interesting problem in my hands. I've written my own modules to engine itself and whenever I add a benign piece of code into certain C++ files, I get a crash during intial loading saying "Virtual functions table is invalid." (being thrown from UObjectBase::IsValidLowLevelFast). The odd part is that, the addition I make does not have to be code at all. Even comments can cause this problem.. Anyone has any solution or even a suggestion to where should i start probing?

@astral sapphire I've found a really frustrating workaround. If I change the file name, that changes the paging of compilation which fixes the issue. Still it bugs me a lot thou

4.23 forked out of Master

#

Master is now 4.24

elder falcon Jun 13, 2019, 3:22 PM

#

br_egg

#

they didn't finish insights for 4.23 then

granite dust Jun 13, 2019, 4:50 PM

#

A 4.23 fork doesn't necessarily mean it's feature complete

#

They added quite a few raytracing features after forking 4.22

thick storm Jun 13, 2019, 5:20 PM

#

idk why they are forked now

#

if in the week they close office for 2 weeks for some holidays or sth

astral sapphire Jun 13, 2019, 8:36 PM

#

4.23 does not compile on VS2019

#

thanks to Hololens

not super surprising

you get these always when new VS gets out

#

also what do you mean by 4.22.3? it's not listed on github for me

#

@astral sapphire

#

4.22.2-release is latest here: https://github.com/EpicGames/UnrealEngine/releases

#

also on https://github.com/EpicGames/UnrealEngine/tree/release

im getting this error when clicking the visual studio's local windows debugger button on a source code build, can't find an answer in google with this particular dll mentioned, anyone's had this issue?
UE4Editor-UnrealEd.dll is either not designed to run on windows or it contains an error. Try installing the program again using the original installation media. Error status 0xc000012f.

@spiral mortar what are the tools for generating terrain and such on your voxel plugin?

#

i want to experiment a good deal with a procedural RPG prototype, and i need something for the terrain, was thinking of voxelplugin, given that unreal terrain is static

spiral mortar Jun 14, 2019, 5:17 PM

#

@brisk silo There are many tools

#

What kind of proc gen?

astral sapphire Jun 14, 2019, 5:29 PM

#

@teal plinth what build are you using?

#

📎 screenshot.1560533493.png

teal plinth Jun 14, 2019, 5:31 PM

#

development editor

#

nvm

#

4.22.2

astral sapphire Jun 14, 2019, 5:32 PM

#

yeah, i was talking about solution build

#

@teal plinth the issue you have is the dll is not compatible with the binary, you may delete it and hit build again...also, afaik Dev Editor is limited in terms of debugging

#

i.e. you can debug games on it, but not the editor itself

teal plinth Jun 14, 2019, 5:37 PM

#

alright thanks ill try to delete the dll and rebuild

astral sapphire Jun 14, 2019, 5:37 PM

#

not "re build"

#

cause that will probably clean the project

teal plinth Jun 14, 2019, 5:38 PM

#

oh my bad i didn't know they were different options

astral sapphire Jun 14, 2019, 5:38 PM

#

yeah, rebuild is like, from scratch

#

@teal plinth oh, also, remove the Intermediate folder (from the project)

#

if that won't help, i assume you may need to delete Engine\Intermediate\Build\Win64\UE4Editor or even whole Engine\Intermediate\

#

but that;s essentially "rebuild"

#

i hope we're talking about editor build...

#

and not project build

#

sorry, have to go, bbl

teal plinth Jun 14, 2019, 5:45 PM

#

ok thanks if I get stuck Ill ask

brisk silo Jun 14, 2019, 5:47 PM

#

@spiral mortar i want to generate a terrain with a couple biomes and mountains and stuff, and then run some post for rivers and towns/paths

spiral mortar Jun 14, 2019, 5:48 PM

#

How large would your terrain be?

brisk silo Jun 14, 2019, 5:49 PM

#

pretty large

#

and done at runtime

#

of course LOD-d to hell

spiral mortar Jun 14, 2019, 5:49 PM

#

ofc

#

How do you plan on doing rivers?

#

Hole in the terrain + water plane?

brisk silo Jun 14, 2019, 5:51 PM

#

spline that carves a path on the voxel terrain + procgen-d mesh

#

more or less same thing for paths

spiral mortar Jun 14, 2019, 5:52 PM

#

👌

brisk silo Jun 14, 2019, 5:52 PM

#

i want to do some experimentation/ R&D about basically a "procedural skyrim"

#

of course wont really happen

#

but wanna tinker a bit now that i know much more about high end performance optimization for huge maps with unreal

spiral mortar Jun 14, 2019, 5:54 PM

#

The main tool I have to play with procgen are voxel graphs

#

📎 unknown.png

#

Lets you experiment with noise pretty quickly

brisk silo Jun 14, 2019, 5:54 PM

#

yeah thtas great for a start

#

but what about multiple biomes?

spiral mortar Jun 14, 2019, 5:54 PM

#

How do you want to generate your biomes

#

Cuz that's the tricky part

brisk silo Jun 14, 2019, 5:55 PM

#

voronoi

spiral mortar Jun 14, 2019, 5:55 PM

#

So precomputed?

brisk silo Jun 14, 2019, 5:55 PM

#

no

spiral mortar Jun 14, 2019, 5:56 PM

#

precomputed at runtime

brisk silo Jun 14, 2019, 5:56 PM

#

the idea is some kind of islands/contintent

#

each island has 2-3 biomes out of N possible ones

spiral mortar Jun 14, 2019, 5:57 PM

#

Yeah so you'd precompute the biome map on start

brisk silo Jun 14, 2019, 5:58 PM

#

yup

spiral mortar Jun 14, 2019, 5:58 PM

#

Ok good

brisk silo Jun 14, 2019, 5:58 PM

#

but there are quite a few possibilities

#

like, if i choose 2 or 3 biomes and i have 6 total biomes... thats a lot of biome combinations

#

what you are suggesting is to have multiple graphs with multiple biomes per graph, no?

#

guess ill have to see if JIT could happen. You are generating the code, no?

spiral mortar Jun 14, 2019, 5:59 PM

#

Why are you talking of biome combination?

brisk silo Jun 14, 2019, 5:59 PM

#

would it be possible to hack the stuff so its 1 function per graph and combine them dynamically with a math formula?

spiral mortar Jun 14, 2019, 6:00 PM

#

You get the values from your biomes, you lerp them

#

End of the story no?

brisk silo Jun 14, 2019, 6:00 PM

#

ah

#

yeah, more or less. But merging biomes is notoriously tricky

spiral mortar Jun 14, 2019, 6:00 PM

#

Yup

brisk silo Jun 14, 2019, 6:01 PM

#

also, what about layered generation

spiral mortar Jun 14, 2019, 6:01 PM

#

wdym?

brisk silo Jun 14, 2019, 6:01 PM

#

like running multiple graphs, one after another

#

one graph postprocesses the data of the one before it

spiral mortar Jun 14, 2019, 6:01 PM

#

Why not have a single one?

brisk silo Jun 14, 2019, 6:01 PM

#

for composability

#

uhm, ill have to tinker around

spiral mortar Jun 14, 2019, 6:01 PM

#

You can use macros

brisk silo Jun 14, 2019, 6:01 PM

#

i was thinking of rolling the mesh generator myself

#

but voxelplugin could be helpful for prototyping

spiral mortar Jun 14, 2019, 6:02 PM

#

But if needed you can sample a graph inside another graph

#

Yeah, unless you need volumetric terrain you're probably better off writing a heightmap mesher

#

Although who knowns, maybe the plugin will be fast enough

#

Lots of crazy optimizations 😄

brisk silo Jun 14, 2019, 6:03 PM

#

thats kinda it. I dont really need 3d terrain other than for a few things

spiral mortar Jun 14, 2019, 6:04 PM

#

Well either you need it or not lol?

brisk silo Jun 14, 2019, 6:04 PM

#

for now its just a prototype, i want to use it as an experimental crazy tech thing and then maybe use parts in other projects

#

@spiral mortar most of the biomes just dont need 3d terrain

#

at all

spiral mortar Jun 14, 2019, 6:04 PM

#

No caves?

brisk silo Jun 14, 2019, 6:05 PM

#

caves will be a special case. Iwont really generate them with the terrain itself

spiral mortar Jun 14, 2019, 6:05 PM

#

🤔

brisk silo Jun 14, 2019, 6:05 PM

#

tho if im using the plugin, some good old perlin-worming could work great for caves

spiral mortar Jun 14, 2019, 6:05 PM

#

ye

brisk silo Jun 14, 2019, 6:05 PM

#

i do want more dungeons than caves, and for that i was thinking of just making a massive hole underground and put 3d meshes for the dungeon pieces inside

#

likely literally unload the main terrain once you enter

spiral mortar Jun 14, 2019, 6:06 PM

#

I see

#

eg switching to a dungeon culling system

#

makes sense

#

Anyways if you plan on using the plugin you should join the discord

brisk silo Jun 14, 2019, 6:10 PM

#

hows the 4.22 support?

#

i kinda need that verison XD

spiral mortar Jun 14, 2019, 6:11 PM

#

@brisk silo It's fine

brisk silo Jun 14, 2019, 6:12 PM

#

btw, have you seen that 4.23 will have raytracing on procedural meshes?

spiral mortar Jun 14, 2019, 6:12 PM

#

Nope

#

I guess that answers why raytracing wasn't working

#

lol

brisk silo Jun 14, 2019, 6:12 PM

#

they merged it to devrendering a couple days ago

#

so i guess you can now do RTX voxesl

spiral mortar Jun 14, 2019, 6:12 PM

#

As I don't have a RTX or even a compatible pascal I haven't looked much into RT for now

brisk silo Jun 14, 2019, 6:13 PM

#

dont worry, rtx support is absolute trash at the moment

spiral mortar Jun 14, 2019, 6:13 PM

#

lol

brisk silo Jun 14, 2019, 6:13 PM

#

i need to grab 4.23 and test RT on that one

#

they made huge improvements

thick storm Jun 14, 2019, 6:14 PM

#

@brisk silo landscape is getting procedural brushes

brisk silo Jun 14, 2019, 6:14 PM

#

@thick storm at runtime?

thick storm Jun 14, 2019, 6:14 PM

#

ah no

spiral mortar Jun 14, 2019, 6:14 PM

#

Better not

#

:p

thick storm Jun 14, 2019, 6:14 PM

#

landscape is not editable at runtime

brisk silo Jun 14, 2019, 6:15 PM

#

@thick storm i would be running houdini if it was about the edit-time

#

i already made some tests of procedural landscapes with it, and it is beyond OP

#

and it got even stronger on latest version

elder falcon Jun 14, 2019, 6:15 PM

#

ray tracing on proc meshes is br_egg

#

it uses a weird dynamic ray tracing instances thing instead of the normal one

brisk silo Jun 14, 2019, 6:16 PM

#

thats.. shit

#

shouldnt it give the option or something?

#

if you want a static RT or dynamic RT

elder falcon Jun 14, 2019, 6:16 PM

#

the proc mesh component can't use static draw list anyway

#

or whatever it is called now in 4.22

spiral mortar Jun 14, 2019, 6:17 PM

#

uh

#

right

Something fun I worked on last year. Erosion on terrains in ue4. I hope to be able to integrate this properly into the engine at some point, or release a plugin, but its a ways off currently. Other aspects of terrain are being worked on though :)

they made a dynamic ray tracing instances thing similar to the GetDynamicMeshElements that sucks

thick storm Jun 14, 2019, 6:18 PM

#

idk looks like cloud replace houdini at least for me ;

#

for runtime procedural terrain I would probabaly go with some off the shelf plugin like the Phyronnaz one

brisk silo Jun 14, 2019, 6:38 PM

#

@spiral mortar what about creating a 2/3d array of raw data from C++ and then reading that data from the voxel graph?

#

is that possible?

spiral mortar Jun 14, 2019, 6:38 PM

#

You can easily create custom nodes

brisk silo Jun 14, 2019, 6:38 PM

#

then thats perfect

#

its because i only really need/want the voxel graph itself for the small scale detail. Stuff like biomes i think would be better to calc on a texture

spiral mortar Jun 14, 2019, 6:40 PM

#

Yeah there's a texture sampler node

noob question, in a source build in the project browser, is the editor not supposed to open after creating a project

limber jacinth Jun 15, 2019, 10:10 PM

#

yes

teal plinth Jun 15, 2019, 10:14 PM

#

thanks

#

is it possible to import assets from the epic launcher to a source build project?

astral warren Jun 15, 2019, 10:17 PM

#

If you cant find the project just untick the checkmark next to the list it should show you the project anyways.

teal plinth Jun 15, 2019, 10:18 PM

#

oh nice that works

#

thanks

#

didn't notice that checkmark

astral warren Jun 15, 2019, 10:19 PM

#

Also, you can install assets from earlier version of the editor, eg an asset for 4.18 should work in a project for 4.22, but not the other way around

teal plinth Jun 15, 2019, 10:55 PM

#

thx Ill have that in mind

atomic radish Jun 16, 2019, 9:12 AM

#

What stops standard base pass translucency from exporting to gbuffer velocity, besides pixel shader outputs ?

shell lily Jun 16, 2019, 9:41 AM

#

@atomic radish pretty sure the translucency pass is just forward rendered after the deferred renderer is done with opaque stuff, so it wouldn't write to the g-buffer at all

atomic radish Jun 16, 2019, 11:14 AM

#

@shell lily I don't see where translucency pass would get different targets and likewise, it uses same shaders, and frankly don't see the reason why you would not be able to write there from translucency. Maybe velocity buffer gets resolved somewhere earlier ?

shell lily Jun 16, 2019, 8:13 PM

#

@atomic radish translucenct materials simply don't write to the G-buffer at all, because of this in BasePassCommon.ush

#

#define USES_GBUFFER (FEATURE_LEVEL >= FEATURE_LEVEL_SM4 && (MATERIALBLENDING_SOLID || MATERIALBLENDING_MASKED) && !SIMPLE_FORWARD_SHADING && !FORWARD_SHADING)

#

and then

#

#define WRITES_VELOCITY_TO_GBUFFER (USES_GBUFFER && GBUFFER_HAS_VELOCITY && (!SELECTIVE_BASEPASS_OUTPUTS || !(STATICLIGHTING_TEXTUREMASK || STATICLIGHTING_SIGNEDDISTANCEFIELD || HQ_TEXTURE_LIGHTMAP || LQ_TEXTURE_LIGHTMAP)))

#

so if USES_GBUFFER is false (as it is for a translucent material) then it's not gonna write velocity either, which makes sense

#

I think when the translucency pass runs, the G-Buffer isn't going to be its render target, the G-Buffer would just be read-only as source textures, and the render target is going to be the main back buffer

strong oxide Jun 16, 2019, 8:40 PM

#

@brisk silo wait what are raytraced landscapes?

atomic radish Jun 17, 2019, 5:37 AM

#

@shell lily I've replaced BegingRenderingSceneColor in BegingRenderingTranslucency with a custom version, that targets velocity, as well as ensuring that USES_GBUFFER is true for shading model in question. It has velocity buffer targeted correctly and exporting there, I'm just missing a resolve somewhere.

shell lily Jun 17, 2019, 5:51 AM

#

ah okay, I dunno, then...to be honest haven't really messed with that code

atomic radish Jun 17, 2019, 9:33 AM

#

Yeah, my problem was resolve, which was done in FSceneRenderTargets::FinishGBufferPassAndResolve. Removed velocity from there and moved it further in translucency finish function. Thanks in any case.

Nowhere, that's a chunk. Without the context it means nothing i guess. Have you try run setup again?

teal plinth Jun 18, 2019, 8:07 PM

#

Move plugin manually from Epic Games\4.XX\Engine\Plugins\Marketplace to your source engine plugins folder or your project/plugins folder.

is this actually safe to do in order to get a plugin from the marketplace into a source build?

astral warren Jun 18, 2019, 8:18 PM

#

it is safe, just drop the binary folder and the intermediate, push a generate.bat for ue4 and it should set you up

#

if you get errors just move the plugin to your project instead

teal plinth Jun 18, 2019, 8:42 PM

#

If you are trying to add a plugin to your project, you will need to create a Plugins folder in the project's root folder and put the source code for the plugin there. Then right-click the .uproject file and select the Generate Visual Studio project files option, open the solution in Visual Studio, and build the project.

Im trying this first

@orchid kayak if you want to see the biggest WTF of How Not To Make A Game Engine

try Torque or Ogre 1.9

#

the Octree of Godot is also a masterpiece

@brisk silo thats exactly what I want to see!

thank you

brisk silo Jun 19, 2019, 4:38 PM

Ogre 1.9 has a great thing

#

Mike Acton, the lead engine developer of Imsoniac, and now the guy who is leading the entire "data oriented tech stack" stuff in unity, did a review of it

#

as an example of precisely how not to do it

elder falcon Jun 19, 2019, 4:39 PM

torque script is a masterpiece: every value is converted to a string and parsed again when you pass it to a function, or store it, or do anything basically

twin nymph Jun 19, 2019, 10:30 PM

#

nothing can be fixed in all these guys are convinced that they're doing the right thing and they're in control

#

godot is gonna keep being bad, ogre , the uh ... the engine from epic games with the asserts

#

also

#

I just hate that my gamedev computer has to be connected to the internet everytime it has to update any goddamn thing

elder falcon Jun 19, 2019, 10:34 PM

#

how else would it update a thing..

twin nymph Jun 19, 2019, 10:35 PM

#

with offline installers and iso files

elder falcon Jun 19, 2019, 10:35 PM

#

br_small_brain

#

way too complicated

twin nymph Jun 19, 2019, 10:35 PM

#

is it a joke ? 😮

#

downloading an install iso, copying it on an usb drive

elder falcon Jun 19, 2019, 10:35 PM

#

the more painless and automatic updating is the better

twin nymph Jun 19, 2019, 10:35 PM

#

openning it, running the installer

elder falcon Jun 19, 2019, 10:35 PM

#

just do something else temporarily while your internet is down

twin nymph Jun 19, 2019, 10:36 PM

#

I don't want my gamedev computer to access the internet

elder falcon Jun 19, 2019, 10:36 PM

#

br_boi_ascended

twin nymph Jun 19, 2019, 10:36 PM

#

i'm fine with downloading a 20gb iso file and install it via a portable hard drive

elder falcon Jun 19, 2019, 10:36 PM

#

why would you overcomplicate it like that

twin nymph Jun 19, 2019, 10:37 PM

#

ffs i'm not saying you have to do the same, i'm saying i'd like to be able to do that with every software

elder falcon Jun 19, 2019, 10:37 PM

#

but I don't understand why

twin nymph Jun 19, 2019, 10:37 PM

#

it's not overcomplicated, it's copying a damn file and running it's installer 😮

elder falcon Jun 19, 2019, 10:37 PM

#

you don't seem to have an actual reason like downloading a huge file once and then deploying it to 100 pcs locally

twin nymph Jun 19, 2019, 10:37 PM

#

I told you why, I don't want my gamedev computer to access the internet

elder falcon Jun 19, 2019, 10:37 PM

#

there's no reason for a single pc to not access the internet

twin nymph Jun 19, 2019, 10:38 PM

#

you have to be trolling

#

a big reason is that I don't want other ppls to see what games i'm developping

elder falcon Jun 19, 2019, 10:39 PM

#

meanwhile I'm wondering if you are trolling

#

using an offline pc in 2019

twin nymph Jun 19, 2019, 10:39 PM

#

I told you why

#

I don't want keyloggers, firewalls,

#

I don't want steam or epic taking infos from my computer

#

to install a program from an Iso file is the simplest thing

#

it's not "overcomplicated" as you're making it to

elder falcon Jun 19, 2019, 10:42 PM

#

it's certainly more manual work than them updating themselves when I launch them

twin nymph Jun 19, 2019, 10:42 PM

#

I propose we keep talking about that in #lounge if it's ok

elder falcon Jun 19, 2019, 10:42 PM

#

there are so many programs to keep track of these days

#

it's already bothering me with 3 vs extensions and live++

twin nymph Jun 19, 2019, 10:42 PM

#

I don't need """"" so many programs """""

#

and yeah, if live++ can't be offline... screw live++

elder falcon Jun 19, 2019, 10:43 PM

#

no I mean having to check if there's an update

#

since it doesn't check itself

astral sapphire Jun 19, 2019, 10:45 PM

#

sorry, but how does ISO install skipping "download" step?

#

You know you could just copy the assets and ue4 to your offline PC, right?

twin nymph Jun 19, 2019, 10:49 PM

#

yes that's how I install UE4, build from source on a machine connected to the internet and then copied to my offline PC

astral sapphire Jun 19, 2019, 10:50 PM

#

you could copy a rocket build as well

twin nymph Jun 19, 2019, 10:50 PM

#

but it's not the case for everything, i'm not sure i'll be able to do that with visual studio

#

what's a rocket build btw Alexey ?

astral sapphire Jun 19, 2019, 10:50 PM

#

the one distributed through launcher

#

it was a code name when ue4 was distributed to licensees

@elder falcon the only issue...will be the Trial license for Community build...i wonder how that works

#

@twin nymph you're not from Iran btw? And especially not from nuclear industry?

#

MS specifically prohibits exporting this software there w/o special US GOV permission. kappa

twin nymph Jun 19, 2019, 11:00 PM

#

@astral sapphire why the hell would I be from Iran ...

elder falcon Jun 19, 2019, 11:03 PM

#

it's because there are like 200 modules for vs, a full installer would be like 100GB

#

so you use a command to make it build one with the packages you need

twin nymph Jun 19, 2019, 11:03 PM

#

several isos , an installer for each feature ? 😊

astral sapphire Jun 19, 2019, 11:03 PM

#

@twin nymph cause...why not? Internet is world without borders (almost), and by using a vpn you could be from any country.
It was a sarcastic note, cause of your "paranoya" precautions.

elder falcon Jun 19, 2019, 11:03 PM

#

that's probably similar to what it's doing behind the scenes

twin nymph Jun 19, 2019, 11:04 PM

#

it would be easier to have several isos

#

right click, download torrent , copy to portable hard drive, done

#

that's how easy it should be

astral sapphire Jun 19, 2019, 11:04 PM

#

ISIS is plural for ISOs...?

twin nymph Jun 19, 2019, 11:04 PM

if you want Alexey, if you want

astral sapphire Jun 19, 2019, 11:05 PM

ok, sorry, not #lounge

@astral sapphire you realize i'm almost at the point of blocking you right ?

@twin nymph I have no intention to hurt you anyhow. Sorry if I did.

nevermind I had to build the server again

torn musk Jun 20, 2019, 6:34 AM

#

@twin nymph how do you plan to Build offline, without Epic's Swarm accessing the Internet? Isn't it mandatory for the building process or did I understand it wrong?

twin nymph Jun 20, 2019, 12:41 PM

#

@torn musk I just download the dependencies and build either on my laptop or my work PC, there's all the infos on epic's UE4 documentation, the "build from source" page

#

all that is needed is the source and the dependencies, in the latest versions the dependencies are downloaded all together ( no separation between mac android linux and core dependencies )

elder falcon Jun 20, 2019, 12:45 PM

#

swarm is this ancient thing for building lights with multiple pcs on the local network it has nothing to do with building the engine

#

nor does it require internet to do its thing

twin nymph Jun 20, 2019, 12:46 PM

#

riiiight 🤦

#

I thought it was the name of the program downloading the dependencies or something

elder falcon Jun 20, 2019, 12:46 PM

#

isn't that thing literally called dependencies.exe

twin nymph Jun 20, 2019, 12:47 PM

#

it is... but Soljenitin mentioned swarm so I thought... etc

elder falcon Jun 20, 2019, 12:47 PM

#

gitdependencies

twin nymph Jun 20, 2019, 12:48 PM

#

you mean it's based on a program from git called gitdependencies ?

elder falcon Jun 20, 2019, 12:48 PM

#

the dependencies thing is really annoying

#

no they made it

twin nymph Jun 20, 2019, 12:48 PM

#

argh too bad

#

honestly , comparing to all the CMake and Scons projects, I find building UE4 very easy

elder falcon Jun 20, 2019, 12:48 PM

#

that's because ubt extremely good

twin nymph Jun 20, 2019, 12:49 PM

#

to be fair, most mainstream opensource projects are rather well documented in terms of source building

elder falcon Jun 20, 2019, 12:49 PM

#

things like cmake get made by linux people who are used to annoying complicated command line stuff and cryptic error messages, so ofc it's not user friendly

twin nymph Jun 20, 2019, 12:49 PM

#

except ubt is also the thing that... in tandem with UHT cripples the building times on the UE4 c++ projects right ?

#

yes ofc indeed

#

or if ubt is only for building UE4, yeah it's rather well done

elder falcon Jun 20, 2019, 12:50 PM

#

ubt is the thing that builds everything

#

and launches uht when it needs to be run

twin nymph Jun 20, 2019, 12:51 PM

#

i'm tempted at trying to make a cuda/ C version of UBT and UHT ...

#

I know it sounds silly

elder falcon Jun 20, 2019, 12:51 PM

#

uht is written in c++ already

#

ubt seems to be fast enough as it is

twin nymph Jun 20, 2019, 12:51 PM

#

ubt is c# tho isn't it ? or does it just takes .cs files as an input

elder falcon Jun 20, 2019, 12:52 PM

#

it barely has a few seconds overhead on executing thousands of actions

twin nymph Jun 20, 2019, 12:52 PM

#

Zeblote no it's not 😮 60seconds total building time on a simple UE4project

elder falcon Jun 20, 2019, 12:52 PM

#

well if that time is actually spent compiling it's not ubts fault

#

it just launches the compiler

twin nymph Jun 20, 2019, 12:53 PM

#

but it also generate huge generated.cpp files taking ages to compile

#

and forces the engine to compile locally for every project, resulting in huge "intermediate" folders

#

altrough I might not be qualified to make further statements in this domain

elder falcon Jun 20, 2019, 12:53 PM

#

fast compile checklist: use IWYU, turn off unity builds for your modules, make a custom pch if necessary

twin nymph Jun 20, 2019, 12:54 PM

#

it's gonna save three seconds at most 😦

#

but ok i'll try

elder falcon Jun 20, 2019, 12:54 PM

#

it takes < 10 seconds for me to build iteratively and like 30 to compile all 70000 lines from scratch

twin nymph Jun 20, 2019, 12:54 PM

#

yes but you might have a ryzen x 999999 and kilometers of ram

elder falcon Jun 20, 2019, 12:55 PM

#

I have a 7820x that's a few years old

twin nymph Jun 20, 2019, 12:55 PM

#

hmmm that's noice

elder falcon Jun 20, 2019, 12:55 PM

#

gonna replace it with a ryzen 12 core tho you're right

twin nymph Jun 20, 2019, 12:55 PM

#

imo... when it works don't replace it

#

but then again, you'd have <4second compiling times

#

I know almost nuthin' in this domain

#

btw Zeblote you meant this tool as well right ? https://include-what-you-use.org/

elder falcon Jun 20, 2019, 12:57 PM

#

no not a tool, it's a set of rules you follow when writing code

#

there's something on it on the unreal docs

twin nymph Jun 20, 2019, 12:58 PM

#

and do you know if there are tutorials to make a custom pch ?

#

i'm gonna find them, also this is nice https://docs.unrealengine.com/en-US/Programming/BuildTools/UnrealBuildTool/IWYU/index.html

IWYU

#

much thanks for these infos

elder falcon Jun 20, 2019, 1:02 PM

#

our build.cs looks like this

📎 unknown.png

#

the pch thing probably isn't really necessary

twin nymph Jun 20, 2019, 1:03 PM

#

hm hm

elder falcon Jun 20, 2019, 1:03 PM

#

in it I just added a few big files we include often but for some reason aren't part of the default pch

#

📎 unknown.png

#

the pch then needs to be rebuilt basically never but it improves your iteration times

torn musk Jun 20, 2019, 1:14 PM

#

@twin nymph , @elder falcon thank you for the clarification on this ancient thingy called Swarm Agent 😃

#

Include What You Use sounds good imho

twin nymph Jun 20, 2019, 1:15 PM

#

@torn musk np 😊 @elder falcon and yeah i'm gonna try to optimize all this tonight that's awesome

brisk silo Jun 20, 2019, 4:05 PM

#

@elder falcon precompiled header is a double edged sword

#

it also means all your files now need to include a megafuckton of lines of code, even if precompiled. It can fairly easily increase your compile times unless you are careful with it

elder falcon Jun 20, 2019, 4:07 PM

#

I have been careful with it, only adding huge files missing from the normal pch

#

it decreased both iteration and full rebuild times even tho it has to wait like 20 seconds for the pch to build at the start

#

that MeshDescription.h thing especially, because it takes for-fucking-ever to parse that big template

#

completely ruins iteration times to include it anywhere without pch

brisk silo Jun 20, 2019, 4:11 PM

elder falcon Jun 21, 2019, 6:07 AM

#

yeah

ornate topaz Jun 21, 2019, 5:35 PM

#

Would one expect to be able to build UE4 from source with the following in one's BuildConfiguration.xml:

#

<bUseSharedPCHs>false</bUseSharedPCHs>
<bUseUnityBuild>false</bUseUnityBuild>```

#

It almost works, except for SymbolDebugger and WebRTCProxy which are missing some #include's.

#

Not sure if it's just an unsupported configuration, but the fact that it very nearly does work and is resolved by adding the missing includes, leads me to believe it's a bug.

astral warren Jun 21, 2019, 6:12 PM

#

You can probably exclude webrtcproxy from your compilation it is only an external app for pixel streaming

ornate topaz Jun 21, 2019, 6:21 PM

#

ah okay, yeah i wasn't sure how much of this was optional

astral warren Jun 21, 2019, 6:25 PM

#

Yes it is optional, there is no need for that unless you want pixelstreaming fsr

shell lily Jun 21, 2019, 7:23 PM

#

@ornate topaz Epic mostly uses unity builds in their workflow, so I've heard if you want to disable them from time to time there are some files you'll have to fix includes for because whoever made the changes didn't

ornate topaz Jun 21, 2019, 7:26 PM

#

@shell lily that would definitely be my guess in this case -- the only reason i was building unreal without unity is i had a buildconfiguration.xml laying around (from a game project) which disabled unity, and unbeknownst to me, unreal was using it as well

last cypress Jun 22, 2019, 12:12 PM

#

you could disable unity build only in your project, not in the whole UE4 by bUseUnityBuild = false; in *.Target.cs

Anybody around that can talk about doing a RenderTarget Texture Read?

#

Ive had an issue since an upgrade to 4.22 where some existing code we had now fails down in D3D land, but our code really didnt change with the update

#

I know a lot of the lighting and rendering did, but Im also not the graphics guy who wrote all this stuff originally so Im a bit out of my element

#

Mostly just trying to figure out how to debug an error that just tells me "One or more of the arguments are invalid" no idea what thats actually telling me

@hearty sand if you retrieve the root path to the Engine then you can check for the presence of the Engine/Build/InstalledBuild.txt sentinel file, which only exists in Installed Builds such as those downloaded through the Epic Games Launcher.

Hi, what is the best choice to do ci (on both windows and Linux)?

shell lily Jun 25, 2019, 8:04 AM

#

well, Epic uses Jenkins and it's pretty popular in general amongst game companies

#

but you could in theory use whichever one you wanted to, since all the build processes can be done via command line

limber jacinth Jun 25, 2019, 1:12 PM

doesnt epic also use GameSync ?

#

te tool they wrote themselves

gray bay Jun 25, 2019, 2:52 PM

yes

Epic used Jenkins in the past, but switched to Electric Commander a few years ago

Anybody use some SceneCaptureActors and might understand some of the changes that happened with capturing scenes to render target textures in 4.22?

frozen glen Jun 25, 2019, 8:24 PM

#

@celest viper What issue are you having?

celest viper Jun 25, 2019, 10:05 PM

#

@frozen glen Sorry bout that been away from my desk. Been trying to track down a DX crash while doing a scene capture from a game thread (in the editor)

#

I think I might have something now, some changes in D3D11UniformBuffer

#

with the 4.22 release

shell lily Jun 25, 2019, 10:07 PM

#

Are you doing deferred capture?

#

Or like capture on every frame?

#

I’ve been using them in 4.22 without issue

celest viper Jun 25, 2019, 10:08 PM

#

ok well maybe you can help me out, Im trying to cover some bases while our render guy is out

#

So not doing it every frame, were queueing up a bunch of captures from different angles to build up data for a dynamic lighting scenrio in the editor

#

At the end of the day Im getting an error that the texture were trying to read the values back out of wasnt setup correctly (essentially doesnt have the D3D11_CPU_ACCESS_WRITE flag)

#

It looks like that part of the UniformBuffer code changed if pooling is not enabled (see FD3D11DynamicRHI::RHICreateUniformBuffer) which seems to be true if youre doing this out of the game thread

shell lily Jun 25, 2019, 10:13 PM

#

Are your targets just the normal render target resources or do you have something custom for that?

#

Cause I’m only using them just with making the render target asset in the editor etc

celest viper Jun 25, 2019, 10:15 PM

#

Custom since this all running on the C++ side but pretty much using the default settings for a Render Target:

#

     renderTarget->InitCustomFormat(128, 128, PF_FloatRGBA, true);

#

Bah, something like that, some psuedocode version of what Im looking at

shell lily Jun 25, 2019, 10:21 PM

#

So which thread is the render target being created on? Is it the same one you’re trying to capture from?

celest viper Jun 25, 2019, 11:10 PM

#

It looks like everything should be happening on the main thread.

#

and bah I think I just have somebody to smack when they get back

#

For some reason this code was, in general, disabling "r.UniformBufferPooling" before starting all the captures and then setting it back to its original state later

#

which would explain why the changes in D3D11UniformBuffer would affect us, were running our captures in a mode different then how we were pre 4.22

shell lily Jun 25, 2019, 11:34 PM

#

ah

hidden fjord Jun 26, 2019, 7:03 AM

#

When you accidentally build the editor instead of your project.

shell lily Jun 26, 2019, 7:14 AM

#

yeah one of the rite of passages is that if you "rebuild" your game project it also rebuilds the engine

#

actually there was a funny bug on installed builds on Mac back in the early 4.1/4.2 days, where if you "cleaned" the project in Xcode, it would delete all of the compiled binaries from the installed build, lol

hidden fjord Jun 26, 2019, 7:23 AM

I just hit the wrong button for this one. All I was trying to do was get plugins into my project. Oops.

mossy patio Jun 26, 2019, 5:06 PM

#

Has anyone out there had any luck detecting controller type?

#

I'm poking around in engine code, specifically around implementations of IInputDevice

#

Seems like it would be quite a pain to dig in and feed a device type through input event handling

#

just curious if anyone's dealt with this, and how

shell lily Jun 26, 2019, 7:52 PM

#

@mossy patio like figure out if it's Xbox vs PS4 controller?

mossy patio Jun 26, 2019, 7:53 PM

#

yeah

#

ps3 xbox360 etc

shell lily Jun 26, 2019, 7:54 PM

#

so first, by default Unreal on Windows only supports XInput devices. so dualshock controllers don't work unless you use one of the hack XInput drivers

mossy patio Jun 26, 2019, 7:54 PM

#

I'm poking around in FWindowsApplication for ideas, just figured I'd ask around to see if there were any thoughts on it in here

shell lily Jun 26, 2019, 7:54 PM

#

so what I ended up doing was I made a plugin that wraps SDL's Game Controller stuff as a new input device

#

because it supports XInput as well as other controller types

mossy patio Jun 26, 2019, 7:55 PM

#

SDL?

#

so then that got me supporting basically all reasonable types of controllers

mossy patio Jun 26, 2019, 7:55 PM

#

nice

shell lily Jun 26, 2019, 7:57 PM

#

then in the SDL source itself, there's a private header that they use to figure out the type of controller based on the vendor ID and product ID of the controller device

#

so I took that also and put it in my plugin

#

then I was able to make some blueprint library functions for like asking which type of controller player X has connected

#

and then I made a custom RichTextDecorator so in a rich text field you can be like "I want the button icon mapping to the Jump action"

#

and then it'll figure out what type of controller you have, look at the action mappings, and show the correct button

#

nice thing about using SDL also is it works on PC/Mac/Linux, though I have not tried it on Linux yet

#

though I know the Unreal source on Linux is already using SDL anyway

#

if you just want to add DualShock 4 support, there is a WinDualShock plugin also, but it's only available to licensed Sony console developers so that doesn't really help most people

#

and then it still would only be XInput plus DualShock 4

#

so it wouldn't support like Nintendo Switch Pro (which SDL does)

mossy patio Jun 26, 2019, 8:58 PM

#

my current plan is to look at the vendor id / product id for a few specific cases (DS4, Steam controller, DS3, XBox One), and otherwise default to Xbox360 layout, which seems to be the convention

#

I don't think i can match it to the controller thats actually providing input, but this may be good enough for now

#

i don't know a whole lot about the vendor id / product id convention, so i don't know if those change at all by region / revision

shell lily Jun 26, 2019, 9:36 PM

#

Well one thing to watch for is there are multiple ids for those controllers that are commonly used

#

@mossy patio here’s the file I used to figure out controller types

#

As far as I know it’s the same list of controllers that steam officially detects so should be good

#

hey does anyone know if the loading thread uploads GPU resources directly, or does it hand that off to the game thread first

#

as nice as it is to async stream assets, once they're loaded im getting a hitch when i then apply them to an actor

long wave Jun 27, 2019, 9:59 AM

#

@mossy patio there isn't really an easy way to do it, however the latest version of the Steam SDK allows you to determine whether the player is using PS4 / Xbox / Steam controllers.

If Im queueing up a bunch of jobs to be threaded that derive from IQueuedWork, do I need a way to tell the thread to kill itself when Im done?

I am currently having "swarm is failing to kick off, rebuild lightmass" errors. I have rebuilt UnrealLightmass and I still have these issues. Was wondering if there was an extra step to fix this

@long wave @shell lily UPDATE. So today i futzed around with writing an unreal plugin that hooks into raw input and registers for input from known gamepads (based on vendor / product id)

#

doesn't touch the underpinnings of the unreal engine, tacks on the functionality as a plugin, which i quite like

#

problem: devices registered to provide raw input event data aren't actually coming out the other end (the processmessage handler of the windows api)

#

I ... don't really know what to do at this juncture beacause nothing is reporting any errors. Perhaps something somewhere is intercepting the event, but i don't know how to find out where it's going.

#

(the idea being i react to input from those and note the most recently used gamepad, and assume that it is the gamepad the player is using)

#

It's super weird, the devices (XBox One controller, for example) successfully registers for input, but then no input is processed

shell lily Jun 27, 2019, 9:08 PM

#

You could look at Epic’s Raw Input plug-in and see how they’re doing it

#

Also I’m not entirely sure whether Raw Input works completely with XInput devices like an Xbox Controller. It’s pretty common to still use XInput for devices that still support it

#

You’re also going to have a bit of a problem in that for XInput devices you’ll get double inputs from both the built-in and your plug-in

mossy patio Jun 27, 2019, 9:47 PM

#

Yeah thats what I’m thinking: Xinput is likely handling and blocking whatever raw input is trying to read.

#

Technically I’d be fine with double inputs. I have no intention of handling the input, I just want to read the device providing it.

#

The raw input plugin doesn’t seem to do anything mine isn’t, but I’ll need to dig more.

#

I need to figure out how XInput reads the controller input, perhaps my answer lies there.

shell lily Jun 27, 2019, 9:56 PM

#

Oh I see, you just want to know what the last input was so you can show the right icons and such?

mossy patio Jun 28, 2019, 2:16 AM

#

basically

#

XInput is a bit of a black box unfortunately, having trouble figuring out the implementation

Is there a practical way to destroy a SceneView mid render? Ive inherited an algorithm that does a shit ton of screen captures in a single frame and ultimately its running me out of memory.

#

So I can either try and break it up across multiple frames, or figure out a way to tell the engine once Ive captured to target and pulled the data out Im done wiht it and we can drop it

frail swallow Jun 29, 2019, 11:39 AM

#

Hi There, is there anybody who came across depth issues on MRT passes? For example one target output with correct depth and the other target ignores the depth?

frail swallow Jun 29, 2019, 12:42 PM

Never mind, resolved by depth actions

did you compile ShaderCompilerWorker also?

dreamy minnow Jun 29, 2019, 10:57 PM

Hey guys, has anybody ever touched the landscape code in unreal? specifically vertex manipulation from the landscape vertices

spiral mortar Jun 29, 2019, 11:31 PM

#

Why?

dreamy minnow Jun 29, 2019, 11:55 PM

#

I want to give them a differen base shape (different from a default grid) and want to differently handle the influence of the heightmap (not just adding/subtracting on the z coordinate)

low dust Jun 30, 2019, 6:54 AM

#

why?

#

@dreamy minnow the whole point of landscape/terrain systems in general is to have even grid, this is like the core basis on how this system works, how it's optimized rendering can work etc

#

if you need something more freeform, you use meshes and get the extra overhead from it

onyx crypt Jun 30, 2019, 1:17 PM

#

@shell lily Yes i did. I tried to run from the visual studio 2017 debug mode and that failed too, after that i tried from the epic store but cant lunch epic store some kind of error 0x0007xb something like that i dont remember now. Than i proceed to see what dll was making the problem and found out that some dll aps-ms-win-core was the problem. Unfortunately that dll cant be downloaded its integrated in the windows, so now im reinstalling windows and i hope i will be able to do some work today spent 2 days debugging whats the problem 😦 .

#

why does my engine keep crashing when i go to save a level. its very random happens about 30% of the time but thats 30% more than it should

#

such an unstable mess

shell lily Jul 1, 2019, 5:55 AM

#

Are you sure it’s crashing and not just an ensure that you can continue past?

dense wharf Jul 1, 2019, 6:36 AM

#

it just freezes

#

like the percentage bar saving

#

I have to ctrl alt del

#

to close it

low dust Jul 1, 2019, 5:17 PM

#

@dense wharf how long did you wait?

#

did you check cpu load with task manager etc?

#

I've had UE4 editor freeze randomly on the dialogs ever since 4.12 and that haven't stopped even in versions today... but it always wakes up like minute or two later.... and if it's not that, it could just really be doing actual work too. if it doesn't update the progress in short while, that sounds still pretty normal, need to be patient with this stuff. and lastly, this is not really #engine-source topic 😃

dense wharf Jul 1, 2019, 11:04 PM

#

I use the source built engine so might be a bug with the build

#

Ive waited 30 minutes and the bar never moved so definitely a lock up of some sort

#

I just upgraded to the .3 version so hopefully it happens less

spiral mortar Jul 1, 2019, 11:07 PM

#

Pause in VS

#

Is anyone familiar with how the engine handles motion blur? It appears that taking screenshots in quick succession causes motion blur to vanish between screenshots (using custom 4.19)

low dust Jul 2, 2019, 8:07 PM

#

@half axle built-in screenshot tool allows you to render one frame at higher resolution for the screenshots

#

this doesn't work for PP effects that rely on multiple frames data

#

like motion blur does

#

there are some other effects you loose as well if I remember right

#

probably lose TAA for example

#

I dunno if you could capture real game footage instead easily, never looked into this

#

if you only need it for promo stuff, just take regular screenshot with print screen 😄

half axle Jul 2, 2019, 8:54 PM

#

Thanks, that at least narrows down where I'll need to build some custom functionality. It's unfortunately core functionality for the product I work on

if I want to use linux do I need to rebuild the whole engine? My server is packaging fine but running it I keep getting an "error while loading shared libraries: libApexCommonProfile.so" message, even though that .so file is in the correct folder

figured I'd rebuild from scratch as a last resort
