Chaos is good enough to be used in Fortnite

ashen kiln Sep 22, 2021, 10:32 AM

#

Yep, if you have a few physics constraints here and there, and also some physics objects around, it'll work fine.

#

async physics thread is best thing about chaos imo.

spring ocean Sep 22, 2021, 11:03 AM

except it was (and still is) completely falling apart with a dozen simulated meshes, every time i look something else is broken

Ragdoll is also not so stable

#

but I still have my hopes up for full release

zealous yarrow Sep 22, 2021, 11:42 AM

#

The idea behind Chaos is great, built in physics replication capabilities, destruction, etc..

But it seems like Chaos development has been going 5 steps forward and 4 steps back with each release, seems like an endless cycle of problems, I hope they know what they are doing with it

lofty idol Sep 22, 2021, 5:54 PM

#

I think tackling reliability is a great goal for a physics engine in context of game development

#

not having a robust networked physics solution is a pretty significant limiting factor

#

I don't mind taking a few hits here and there to achieve that goal imho

torpid valve Sep 22, 2021, 6:46 PM

#

yeah, having fixed tick physics and tight integration with networking is boon for most games

#

it's much more reliable to simulate your typical cases, like projectiles, traces, and even funky things like telekinsesis like abilities

static copper Sep 22, 2021, 8:55 PM

I'm confident they will iron out most of the issues but I do worry for people relying on specific physx things that epic will never care about doing well

Just wanted to bring up this issue and a simple fix I proposed which has been largely ignored:
https://github.com/EpicGames/UnrealEngine/pull/7875 (Change the default FOV to be Horizontal+).
UE5 would be a good time to change it and make all games widescreen compatible.

5.1 👀

#

So, where is 5.0 branch?

#

or, was early access supposed to be 5.0, and full release will be 5.1 in early 2022?

torpid valve Sep 23, 2021, 4:55 PM

#

on perforce (;

#

early access branch

#

is done and not supported

#

either way it's hard to speculate

#

it's usually 1 or more month before the versioned branch is pushed to github

ashen kiln Sep 23, 2021, 4:58 PM

From that point, probably it's dangerous to pull changes on ue5-main then.

The funny thing is that UE3 was Hor+ by default. Pretty much all games from that time had good ultrawide support out of the box. I always wanted to know why they made the decision to change to YFOV, since it made a lot of UE4 games to have broken FOV and cinematics in 21:9.

Having issues building a project for linux with pixel streaming enabled - ue5-main branch, anyone got suggestions on how to fix this issue?

urban fog Sep 23, 2021, 8:57 PM

#

torpid valve I didn't realized there was simple setting for it

Yeah, a lot of devs don't know about that setting, it's kind of hidden away and undocumented. Just like devs don't even know their game would run in widescreen with Ver- fov, if this was default, at least all games would support Hor+ widescreen without even being aware.

#

The widescreen community goes insane trying to fix every UE game for widescreen, and if this was default, boom, they would just all work (at least classic 3d games)

opaque phoenix Sep 24, 2021, 2:52 AM

so I want to try out ue5 source but I have space issues so I have 2 questions - can I have my source on my hard drive and compile elsewhere?

it is there on the roadmap from what I read. That and forward shading support.

I am trying to build ue5-main branch from source(on fast SSD) using vs2022 (preview 4) and its currently compiling (win64 development), but it seems to be using only 1 core and is taking hours (still only about 1/4 thru after several hours) is this typical or is something messed up?

plain lintel Sep 24, 2021, 4:39 AM

#

they could pull a chaos at the last second and disable it until 5.1 or something

ashen kiln Sep 24, 2021, 8:56 AM

#

I think they have lots of to do with engine -> shader variable bindings because of LWC

#

Because of doubles causing buffer overflow on shaders, while being written on floats.

#

but there are still plenty of time until early 2022, so they'll fix those problems probably.

torpid valve Sep 24, 2021, 9:44 AM

lofty idol now I'm wondering if LWC will be enabled on 5.0 by default. 🤔

Last I talked, it was supposed to be ready on 5.,0 no matter what

#

either way there is 5.0 branch but it doesn'treally mean there won't be new features or breaking changes for 5.0

@primal night Normally, it takes around 3 months for full release after version branch is pushed into github.

#

So, early 2022 for release still holds on

#

The issue is, we don't have the version branch yet, and I hope they push it soon :/ Otherwise, many people will be stuck at this state, because upgrading to latest commit on ue5-main will break compatibility with upcoming 5.0 release.

Are you sure it works faster? 🤔

strong agate Sep 24, 2021, 6:31 PM

#

I think it's possible in some cases, CSM can get hairy if you have a lot of meshes closely together, like in a city. I saw some comparisons and at least raytracing shadows can be faster than cascade in a city with a lot of buildings

#

I'm not sure if VSM is faster than raytracing shadows

compact swift Sep 24, 2021, 7:41 PM

#

Hello community !! How is it ue5 going ?

lofty idol Sep 24, 2021, 9:39 PM

#

Virtual shadows can be faster in dx11 too

#

you just need to have a detailed scene where the cost of cascaded shadows is simply too high

#

you don't even need to do fancy stuff, enough small details and you can get the same result with a flat terrain too

#

Now, obviously, if you don't have lots of small details, virtual shadows will be slower

#

I see it like deferred rendering but for shadows

#

if you have lots, its way faster

#

as far as I'm concerned, its black magic

torpid valve Sep 24, 2021, 10:38 PM

VSM is more like virtual textures

Is UE5 a rewrite from the ground up or an overhaul of the UE4 source code?

neither

oblique mist Is UE5 a rewrite from the ground up or an overhaul of the UE4 source code?

unlikely an overhaul. Game engines that are there in the market currently have had their code built up over 20+ years. their main function is likely untouched since it was first written for example.

wheat salmon Sep 26, 2021, 11:43 AM

well it explicitly stated to use 32 cores in UE4^^

#

so I don't get what has changed that it decides to need more mem in UE5

torpid valve Sep 26, 2021, 11:44 AM

#

for compiation you need at least 1.5GB per thread

wheat salmon Sep 26, 2021, 11:44 AM

#

which is 48 GB

#

and even if I couldn't use 32 cores, is there a setting to specify how many cores to use? since there is enough cores left, even if I don't utalize all 32

#

I just need to add a setting to the build configuration that increases the ProcessorCountMultiplier 😄

#

No idea, but I'm also now on 5.1

#

BuildConfiguration.xml

<?xml version="1.0" encoding="utf-8" ?>
<Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
    <ProjectFileGenerator>
        <Format>VisualStudio2019</Format>

    <ParallelExecutor>
        <ProcessorCountMultiplier>2</ProcessorCountMultiplier>
      <MemoryPerActionBytes>0</MemoryPerActionBytes>
    </ParallelExecutor>
</Configuration>

#

and now it limits the thread to the available memory

#

xD yeah, I also never had issues with memory

#

yes it is

#

I did a string search xD

#

I was very irritated that my engine rebuild took 30 minutes instead of 15 ...^^

#

and if you also add MemoryPerActionBytes with a 0, you don't need to patch the code (which is a plus since others in my team may need a limitation^^)

#

did they have such an overhead?

#

yes, I updated my example from above

#

you also can limit stuff with MaxProcessorCount

when i try to finish my first ue5-main rocket build

#

i thought that too, thanks i will go nuclear. I hope one day EPIC do not rely so much on .NET stuff who do not need or want it.

#

I am far from programmer and i sometimes just modify code sometimes if i find what it affects but perhaps EPIC should create some mini script backend that do not rely on external runtimes. Just my 2 cents. Yes i understand that is quite huge to make own script engine but? i dont know, maybe there is some possibility.

#

that is true, no argument there.

#

Could be possible to resume building where it left? or it is impossible. Seems that compilation started from scratch( no -clean option in use)

#

thanks for info. just now finished but now with another error by ios trash but i have excluded ios stuff at all

#

i use set:HostPlatformOnly=true

#

how to bypass ios 100%

📎 ios.txt

#

in beginning compiler wanted some ios related dummy image then i gave those .png icons and compile continued fine but seems it backfired.... even i have never wanted that ios, never

#

no idea what it is, is there a way to exclude everything related to ios

#

set:WithIOS=false wont work too

hazy moat Sep 27, 2021, 8:46 AM

#

This InstalledEngineBuild.xml needed mod(Thank you ryanjon2040) to bypass IOS error but i hope in future if using -set:HostPlatformOnly=true or -set:WithIOS=false and not sitting on MAC platform then IOS should be excluded 100%

honestly if they work out well I might just not bother with my flecs integration thingy anymore

#

I'm hardly reaping the benefits of ecs architecture with something this simple (projectile sim)

torpid valve Sep 29, 2021, 9:24 AM

#

from I have seen there is loads of functionality, but hard to say without exactly checking what it does

cedar tree Sep 29, 2021, 9:24 AM

I bet an ECS will always be more cache friendly

torpid valve Sep 29, 2021, 9:24 AM

one implemenation is for massive crowd simulation in engine

#

it might be ECS we will see soon enough (;

static copper Sep 29, 2021, 9:24 AM

#

just being anywhere near lightweight compared to regular actors would instantly help, it doesn't need to be as hardcore as a true Archetype-style ECS

torpid valve Sep 29, 2021, 9:25 AM

#

i honestly would be more than happy to have componenets which does not take forever to add on actor

yeah they can be now async added but it still heavy registration process -;-

#

I figured out, that they should be used to actually add well

#

redunant

#

what i say now

#

game features

#

you should implement the core functionality inside your Game MOdule

#

but do not really use it to create any specific gameplay features, only code which will support adding gameplay things

#

and then add gameplay using plugins

cedar tree Sep 29, 2021, 9:29 AM

#

is C++ plugin less painful now?

torpid valve Sep 29, 2021, 9:29 AM

ie, the game module should be used to integrated various other plugins and expose API to game features plugins

#

can anybody elaborate on smart objects? How can be these useful? From what I saw it looks like some objects around the world which direct AI.

torpid valve Sep 29, 2021, 10:09 AM

#

Sims

#

I mean there is hardly any better explanation than Sims

#

smart objects tell your agent

#

what it should do

#

they encapuslate behavior

#

your agent does not need to know what to do with ue. sandwich

#

it's sandwich telling agent what it should do with it

#

it makes very easy to add new behaviors to game

#

since you never need to touch your agent

solid cypress Sep 29, 2021, 10:11 AM

#

aaah that's really cool. I mean I have been probably doing something similar with objects giving abilities but I am sure this is well beyond that.

it's just a FLWComponentData struct though

spare orchid Sep 29, 2021, 10:45 AM

Fragments are the smallest type of component

thing is that they also pack multiple fragments as one component

you are still going to be bottlenecked by grace of simply deferencing pointer to cmc

cedar tree Sep 29, 2021, 11:11 AM

yea I was surprised how low level the actual movement code in there is

like "integrate along this line and check if we hit a floor"

or so

though I guess that's how it usually is 🤔

torpid valve Sep 29, 2021, 11:12 AM

#

yeap, the code is in particularly cache friendly

static copper Sep 29, 2021, 11:12 AM

#

Do component/tag add/remove actions always get deferred to next frame?
Any hierarchy/grouping features? (not that we really need those)

torpid valve Sep 29, 2021, 11:12 AM

#

moving it to ECS would be more for organizational preferences than for performance

static copper Sep 29, 2021, 11:13 AM

#

I actually kind of wish it was sparse set because that's a bit more appropriate for most games

#

but it seriously does not matter lol

#

as demonstrated by vblanco switching his space battle between two different ECS libs and seeing 0 noticeable change

#

I'm just worried about comp adds being bad

torpid valve Sep 29, 2021, 11:14 AM

#

in the end you are bottlenecked by how fast you can update transforms in unreal in that cases

#

they are crap

cedar tree Sep 29, 2021, 11:14 AM

#

yea it also is pretty... involved

torpid valve Sep 29, 2021, 11:15 AM

#

and for more player centric features like CMC, there are lots of replication/reposnsivnes/edge handling issues where the performance is eaten away

as they actually have a component to add ecs components to an actor while unity doesnt

They just need a system order window

But it will be sooner than unity

#

Ok let's be clear

#

Lyra is new sample

#

But that's all there is to tell

solid cypress Sep 29, 2021, 12:29 PM

#

imo Frosty will be winter presentation for GDC and Lyra game sample. Like the lava trailer and shooter game for UE4 & desert trailer + valley of the ancient for UE5 EA

#

but it is only speculation

static copper Sep 29, 2021, 12:29 PM

That's a smart guess

it would be cool if they did it in multiplayer 😄

torpid valve Sep 29, 2021, 1:18 PM

the real question is

why it is called MassEntity

#

and not MetaEntity : >

spare orchid Sep 29, 2021, 1:31 PM

#

what the fuck is a SmartObject

#

like a smart object has sort of sockets inside to run behaviors

#

the hell is tihs

torpid valve Sep 29, 2021, 1:33 PM

Sims = Smart Object (;

#

smart objects tell your agent what he is supposed to do with them

minor axle Sep 29, 2021, 1:40 PM

this UE's ECS plugin killed my job with my implementation of army 😦

spare orchid Sep 29, 2021, 1:50 PM

thats kinda what i was checking. @torpid valve pretty cool

#

so then they are going pretty ham on AI systems

still absolutely nothing spoken about

solid cypress Sep 29, 2021, 3:31 PM

I just created lane profiles in project settings, placed zone graph data actor, zone shape actors and pressed Build ZoneGraph in the Build menu

#

testing actor is showing how it is projecting to the zone graph

hah ok i missed zone graph data on level then (;

thanks ;

solid cypress Sep 29, 2021, 3:36 PM

and for other fun plugins

ControlFlows

I will maybe investigate that one later. I am afraid that for Mass it will take me week of reverse engineering to get where I could get with docs in 1 day 😅

it's plugin which implement API for well flow of events

don't know that one

torpid valve Sep 29, 2021, 3:41 PM

you can queue up events and they will run in order or wait for other event to complete

torpid valve Sep 29, 2021, 3:42 PM

#

ashen kiln is this early Christmas?

haha there is quite a few interesting stuff, just dont write about it\

#

one things that people don't know about

#

is IK retargeting system

#

it can run at runtime

#

and is more advanced than motion builder

#

you can literally retarget any skeleton to any other skeleton

#

there is also Motion Matching, but thats probably known

#

what is not known is that recently they added default implementation for CMC

#

library of modifiers to generate curves

#

like.. the fortnite money is really invested into the engine

torpid valve Sep 29, 2021, 4:03 PM

#

Motion Matching trajectory prediction based on CMC movement model

#

the UE5 version of motion matching works based on capsule movement not root motion

#

CMC itself is maintained but not really developed ;

foggy wolf Sep 29, 2021, 5:00 PM

#

Anyone know if UE5 World Partition is dynamic, and if we can access/modify it on runtime with c++?
I was hoping I could reuse its nice streaming and grid system to create randomized infinite maps

foggy wolf Sep 29, 2021, 5:17 PM

#

It was just a simple thought, I was thinking if I already had access to the information like current grids, cell sizes etc, I wouldn't need to create just another system that did just the same

#

And you don't need to handle all the cleanup yourself from loading/unloading levels? I don't really know how much gets left behind if you are simply performing these operations constantly over an extended period of time. But then again I don't know WP very well yet either, as you mentioned before they pretty much use the same level streaming as the older WC right?

#

I was planning to test it with something simple like driving down an endless road with some turns, bumps, trees etc, just too test out the performance. If you think doing it manually is the better approach, then I will just go with that 🙂

cedar tree Sep 29, 2021, 5:51 PM

the Mass AI navigation is using the zone graph subsystem

simple lynx Sep 29, 2021, 9:14 PM

If we're going to have mass amount of AIs then I guess UE should be able to render mass amount of SKs too?

they are using ism for the farm test

scenic mauve Sep 29, 2021, 9:16 PM

Hey what is the order of steps when you are going to update your build to the latest version?

git pull
Open up solution file and then build or start new debug instance.
If successful, open up a project solution file and build / start new debug instance.

Is that it? Do you ever need to run any batch files?

I think that tweet I've posted confirms "mass" is related with the amount of agents

But how 'mass' lol

"Mass Crowd Sim" is probably how the name started

nothing really wrong with it, I just love fancy names

static copper Sep 29, 2021, 9:54 PM

smart objects are still a mystery so far

they are regular actors that have a rendering component and some kind of AI logic you can make that they use to interact with it?

they are used by Mass but SmartObject does not require Mass

Ok. I explain it for third time now (;

#

It's from Sims

#

Smart Objects tell your agent, what it should do with them

#

they encapsulate behavior/action

#

so your agent does not need to know how to use it

simple lynx Sep 30, 2021, 5:17 AM

#

I love them too, no more checking if GetWorld() returns a nullptr every time

I wonder how mass entities work interaction wise

like, is it really slow or fast to do line traces against them for example

#

or do overlap checks to them

torpid valve Sep 30, 2021, 6:52 AM

#

you see

#

mass entity

#

does not have any world representation (;

#

there are wrappers around existing systems like Instanced Static Mesh or actor

cedar tree Sep 30, 2021, 6:54 AM

#

well, yes

#

I doubt the use case for mass entities is to run abstract simulations that the player can't interact with 😛

#

or see

torpid valve Sep 30, 2021, 6:55 AM

#

you cloud be surprised (;

#

but in general you are right

#

point being

#

there is no special representation of entities, at least as of now

#

the final rendered part is what it was before

scene component

cedar tree Sep 30, 2021, 7:02 AM

limpid light Sep 30, 2021, 9:34 AM

C# is lovely to work with honestly 🙂 and the "High Perf C#" variant that Unity uses for Burst is great too, its like a subset to get around gc issues and having better memory alignment and cache utilization.

#

#

I'm also hitting a breakpoint due to missing symbols when I run previous versions of the engine and/or projects through visual studio (although the projects themselves work fine when ran from their .uproject). I'm unsure if it's related or not.

limpid light Sep 30, 2021, 3:06 PM

#

Most likely that is due to some files being moved and you might be copying over to a folder you already had a previous version so now you end up with duplicates?

grand epoch Sep 30, 2021, 3:14 PM

#

@limpid light I think you're probably right, but I'm unable to locate those files in the designated location so I'm unsure how to manually remove the main duplicate. I was hoping to avoid rebuilding again as it somehow seems to take my computer 6 hours 🔮 . Any thoughts on finding those files or should I wipe the folder location and start fresh?

limpid light Sep 30, 2021, 3:16 PM

#

When I do engine source upgrades, I have the vanilla version in source control (Perforce). Then I delete all local files, copy over the fresh ones and then run a diff to create the delta to submit.

#

Hunting through and manually removing files that might have been moved or deleted is way too much of a hassle, I've done that in the past 😛 best to start fresh, delete all files and drop in a fresh copy

grand epoch Sep 30, 2021, 3:21 PM

#

Thanks for the advice! I've only been teaching myself since about March so I'm still pretty new, but I've been getting to the point where I should probably have source control set up as well so I'm going to look into getting that situated, then wipe things and start the build process again, really appreciate the input 😄 .

which one ? : D

simple lynx Sep 30, 2021, 7:12 PM

#

All of the Miezsko mentioned

#

Gameplay feature, needed for Fortnite, movie industry, Miezsko just got bored, which one?

#

Epic wanted to open a door for RTS enthusiastics?

torpid valve Sep 30, 2021, 7:30 PM

#

Epic never makes features which they do not use in their games

simple lynx Sep 30, 2021, 7:30 PM

#

I think they do

torpid valve Sep 30, 2021, 7:31 PM

#

no

they dont

the other half are high profile licensees like disney

How it is different from entire async library ?

cedar tree Oct 1, 2021, 3:25 PM

#

so what happens when someone modifies blah? 😛

#

rhetorical question really

torpid valve Oct 1, 2021, 3:36 PM

#

ah so it is supported by compiler and co_await is new keyword ?

#

ok I see it is

#

the good part is Epic adapt new C++ ASAP

#

the bad part is that new C++ standard are suslly held up by consoles

#

read rest (;

cedar tree Oct 1, 2021, 3:37 PM

#

doesn't the engine already have async primitives for doing parallel stuff?

#

or is that all off limits for gameplay code?

torpid valve Oct 1, 2021, 3:37 PM

#

it does

#

it's not languague level support

#

UE5 in particular have all the async libraries enchanced

#

and streamlined

#

on high level it's really easy to write async code in ue

cedar tree Oct 1, 2021, 3:38 PM

#

I'm just wondering what does language level support mean in general. Would the compiler check for race conditions or use after frees in parallel code? Like when system A owns stuff foo and then system B modifies it but whoops A already deallocated it

torpid valve Oct 1, 2021, 3:39 PM

#

lets be honest here

cedar tree Oct 1, 2021, 3:39 PM

#

I suppose in a nutshell: would it be as advanced as what rust does or is it impossible due to C++ being C++ 😄

torpid valve Oct 1, 2021, 3:39 PM

#

in C++ it means another footgun

cedar tree Oct 1, 2021, 3:39 PM

#

yeah

torpid valve Oct 1, 2021, 3:39 PM

#

and no its impossible to do in C++, I mean with reasnable cost to deliver it

cedar tree Oct 1, 2021, 3:40 PM

#

so I suppose keywords like co_await or so would just make the function return a future (or equivalent) under the hood and add yield points somewhere and then execute it in some executor under the hood?

cedar tree Oct 1, 2021, 4:54 PM

#

though with C++ you still need an executor

#

whereas C# I assume comes with an executor in the VM?

Having some new issue building UE5 main branch, anyone come across this error before? If I clean our Intermediate/Saved then I get the same error but in a different file (due to non-deterministic order I guess).

ERROR: Unhandled exception: Dependency file "F:<path...>\Module.InterchangeResultsBrowser.cpp.json" version ("1.0") is not supported. Expected version "1.1"

Update: This is something to do with a sourceDependency generation feature of the compiler, and somehow it seems an older compiler is being run in my instance even though I have the latest VS 2019 installed.
See https://docs.microsoft.com/en-us/cpp/build/reference/sourcedependencies

/sourceDependencies (Report source-level dependencies)

Describes the /sourceDependencies compiler option in Microsoft C++.

i too managed to find a way to hack and bypass iOS error weird way, i inserted fake images(picture) in right place then when compilation showed error in the end THEN i replaced InstalledEngineBuild.xml with iOS stuff deleted and then build was complete success.

a few months ago Epic mentioned they are reworking VCS support, so this could be what they meant

I cloud get all API calls working, just not dashboard

solid cypress Oct 5, 2021, 10:59 AM

#

it was tedious some time ago but now there is just single build graph script which generates you .msi installers for everything :P Then you just need to setup configs and stuff like P4 connection.

torpid valve Oct 5, 2021, 11:00 AM

#

00 might try it later then : D

solid cypress Oct 5, 2021, 11:04 AM

#

It is in Engine\Source\Programs\Horde\Installer\Installer.xml
You will need yarn in os PATH.
But expect reverse engineering for the setup of config. Last time I checked the default config was almost empty, so everything needed to be entered manually. It took me a few hours but then it was nicely automatically triggering build graph script for my project on P4 commits. They added big (mostly) generic build graph script for building, cooking and running simple tests as game startup test. It has also Horde stuff like UGS badges included. That one is in Engine\Build\Graph\Tasks\BuildAndTestProject.xml

#

it has no user management. It supports OpenID and contains implementation only for Okta provider which Epic is using. So to get it running up and quickly you will need to use anonymous mode.

limpid light Oct 5, 2021, 11:14 AM

#

What would you say is the biggest benefit for using Horde over Teamcity/Jenkins and just kicking off a build script yourself? The distributed nature? Like Incredibuild then?

#

Just curious, Ive heard Horde mentioned just never known what it was

solid cypress Oct 5, 2021, 11:16 AM

#

the ability to automatically understand buildgraph scripts. Depending on the buildgraph script setup it can automatically distribute and parallelize it.

limpid light Oct 5, 2021, 11:16 AM

#

nice, so there are even benefits to running it locally on a multi core cpu?

#

working from home has sadly made distributed tools (like Incredibuild) a bit less useful :/

solid cypress Oct 5, 2021, 11:17 AM

#

It is not that granular parallelization. It is parallelization at the task level. So if you are building for Win+Xbox+PS, these three compilations can run on different agents

limpid light Oct 5, 2021, 11:18 AM

#

ah nice, so like an orchestrator

solid cypress Oct 5, 2021, 11:19 AM

#

yes, but surprisingly Horde allows almost no build configuration on website. You just specify P4 connection, schedules, path & parameter to your BuildGraph.xml

limpid light Oct 5, 2021, 11:21 AM

#

ah nice, then you can deliver all configuration through VCS

#

makes the build server setup a lot easier

solid cypress Oct 5, 2021, 11:22 AM

#

For example BuildGraph contains block

<Agent Name="Build $(ProjectName)Editor $(EditorPlatform)" Type="$(HostAgentType)">
...
</Agent>

And Horde will understand it and parallelize it to agents which are of type HostAgentType.
It should also support Gauntlent, so I would expect an ability to communicate with devkits.
I saw some last commits added support for Compute Tasks. These are generic things which need to be calculated. UE5 now contains also some compute tasks like shader compiling/DDC building and so on, so theoretically you will be probably able to let the buildmachine compile your local shaders.

limpid light Oct 5, 2021, 11:22 AM

#

oh thats great, it will make building a windows client + linux server a bit easier

#

today you have to do a lot of configuration on the build server to do those kind of tasks

solid cypress Oct 5, 2021, 11:27 AM

#

yes and it is a pain when you want to redo it again for some reason or transfer the config. We are using TC at work which was my preferred option but with Horde's deep support for UE it will be eventually just too much work to setup other CIS manually.

#

but it is Perforce only

limpid light Oct 5, 2021, 11:36 AM

Perforce only is fine with me 🙂 we are using the hosted solution from Assembla.

I don't think it will be "lite" it will still need quite a bit of inftrastructure to setup

Days Gone Horde..........

primal night What is Horde? 👀

something like Jenkins/TeamCity but from Epic

crystal crescent Oct 6, 2021, 4:45 PM

#

I can not build horde, I get some issue into src/index.tsx api.asumption is not a function

stark basin Oct 6, 2021, 8:08 PM

#

new-live branch should be gone, thanks for bringing it up. It was a mistake

torpid valve Oct 6, 2021, 8:21 PM

#

and so we are left with mystery

;d

not a mystery 🙂 git args were botched in a script during a refactor, but I don't know more details than that

DX12 is highly recommend but for reference if you need to mitigate the additional cost in DX11 you can lower the SMRT sample counts (see docs for cvars). This will lessen the impact on DX11 at the cost of some penumbra quality.

Can you migrate 4.27 assets to UE5-main yet?

vale hill Can you migrate 4.27 assets to UE5-main yet?

I think so I did manage to do it

vale hill Oct 7, 2021, 5:37 AM

#

sweet! (assuming doesnt work with EA2, but does with UE5-main?)

#

4.26 only for EA2 right?

opaque phoenix Oct 7, 2021, 5:41 AM

#

4.26 for EA yes

https://www.youtube.com/watch?v=jse7YKE7Q_0 - I haven't seen anyone mention this yet, but main seems to be adding Geometry Nodes / Houdiniesque control over the modelling tools. This is huge news for procedural workflows.

Geometry Scripting + updates Unreal Engine 5

Wanted to make a basic intro video for geo scripting to people could see whats on the way as well as update on other tools and features that have made there way to UE5 recently sort of a state of unreal video. This isnt meant as a tutorial but just to preview and plan for features that may be coming to the editor for people that are not able to ...

▶ Play video

#

Also, friendly suggestion for the mods: https://discord.gg/pQ67RPyh - Ryan's Unreal Binary Builder server compiles each main version and spits out a "does compile, doesn't compile" message. The link to this should at least be pinned, or even integrated over here. It is extremely useful to know if a commit builds or not and just scrolling up a bit here, one can see messages of people asking or complaining exactly about this.

#

*If this is considered promotion, I'll delete the message. I am in no way affiliated to the server.

ashen kiln Oct 7, 2021, 7:06 AM

Since most of enterprise stuff fails to compile atm, I think this server telling you the build fails doesn't mean it also won't work with your project, as long as you disable datasmith etc.

Did anyone notice this little bit in the video above? 😄 This must be very recent since its not in the UE5-main build I have locally, or I'm missing some other condition.

torpid valve Oct 7, 2021, 8:13 AM

#

it was there

#

but i dont remember if it is on by default on enabled by some cvar config

limpid light Oct 7, 2021, 8:14 AM

#

oh looks like its an optional plugin

#

Ive been waiting for this, it should make creating maps with thousands of "actors" finally plausible (and then relying on World Partition for streaming ofc)

torpid valve Oct 7, 2021, 8:15 AM

#

seems like we have two competing systems

#

xD

#

one is Mass which is actively developed

limpid light Oct 7, 2021, 8:15 AM

#

this and the ECS entities? possibly

torpid valve Oct 7, 2021, 8:15 AM

#

and other Lightweight Instances which seems to be relagetd and used only for editor

limpid light Oct 7, 2021, 8:15 AM

#

Is there editor time support for the Mass entities yet? ie placing and editing entities in a level

#

You mean that "Elements"?

torpid valve Oct 7, 2021, 8:16 AM

#

Mass doesnt work this way

#

at least for now

limpid light Oct 7, 2021, 8:16 AM

#

Yeah thats what I thought, this is needed for level designers who are working on huge worlds

torpid valve Oct 7, 2021, 8:17 AM

#

it is separate systems, which wraps itself around actors

#

Lightweight instances on the other hand seems to be used only for instanced static meshes right now

limpid light Oct 7, 2021, 8:17 AM

#

We have a prototype levels with.. a lot of actors, and our level designers are having issues with the amount of actors and are not liking the "mega asset" workflow so far

torpid valve Oct 7, 2021, 8:18 AM

#

i dont know where is the problem

#

you turn on world partition

#

set grid size to about 64 meters

#

and nobody is forcing you to load everything (;

#

that and if you have truly massive amount of actors you should reconsiders to convert them into ISM/HISM or spawn at runtime

#

reallly depends, but just placing each blade of grass as an actor was never the intetion and LW wont solve it

limpid light Oct 7, 2021, 8:20 AM

#

did all that, but the editing experience is not nice when you just want to move one rock "a bit to the left"

torpid valve Oct 7, 2021, 8:20 AM

#

that I would consider the issue with people at this point

#

been there, seen that

limpid light Oct 7, 2021, 8:20 AM

#

these lightweight instances will give you about the same runtime perf, with a much better editing experience

#

Well, we have a map with over a million mesh instances 🙂 trees, rocks, cliffs etc

torpid valve Oct 7, 2021, 8:21 AM

#

my point

#

at that scale

#

you should avoid manual editing anyway

#

just scatter proceduraly everything

limpid light Oct 7, 2021, 8:21 AM

#

thats the plan 🙂

torpid valve Oct 7, 2021, 8:21 AM

#

with small adjustmants in really important places

limpid light Oct 7, 2021, 8:21 AM

#

yeah thats exactly the approach, and even long term it will all be runtime scattering

#

damn, it doesnt seem to work at all. When I convert an actor into a LWI it just disappears both from the scene and the outliner

@stark basin seems like the sync of ue5-main to Github died a couple days ago?

torpid valve Oct 7, 2021, 9:26 AM

#

recently it seems to die quite often

#

to much commits on p4 and sync cant keep up ?

cedar tree Oct 7, 2021, 11:32 AM

someone just closed the laptop that's running the bash script

Or the cleaning lady unplugged the server while vacuuming. Both are things that I've known to happen IRL ... 😄
