Ok. Thanks.

man nanite wpo would make skeletal possible for nanite

#

So what would barebones nanite potentially look like? For example, I flatten my fps weapons in screen space to make them retain fov and prevent clipping. Would that be a possibility with nanite?

lofty idol
#

Wait, I just noticed windows 10 seems to be stuck on wddm 2.7

#

does that mean nanite will be windows 11 only? 🤔

#

(wddm 2.7 only supports SM 6.5 regardless of hardware, in case you didn't know)

lofty idol
#

Well, that's a bummer. Lots of conflicting information all around. I was tempted to build ue5-main just to test wpo with nanite on my home pc but latest drivers for 1080ti only supports wddm 2.7 on Windows 10 😩

#

Anyone here can get the latest ue5-main work in dx12 sm6.6 with windows 10?

tranquil zenith
#

converting worlds to use world partition still prety much not working still bleh

opaque phoenix
lofty idol
#

All I could find was that Windows 10 insider builds got wddm 2.8 (abandoned) and 2.9, but those insider builds later ended up getting renamed into Windows 11. So it looks like to me that the same way Windows 10 was supposed to get the latest WSL and Android emulation but didn't, wddm was "forgotten" ?

#

¯_(ツ)_/¯

tranquil zenith
#

they have WPO with nanite in the works!??

#

Omfg if that works omg

tranquil zenith
#

If they get masked materials and WPO working with nanite then my mind will be utterly blown away at the possibilities that open up

lofty idol
#

It should work in ue5-main right now (though apparently the branch is a bit crashy nowadays) but it is limited to SM 6.6, hence Windows 11 only (?).

lofty idol
#

is there any point building from source rn compared to using latest early access in the launcher?

eager hedge
#

if you're just going to use the tagged release with no plans to modify source code or build configurations that are only available with source builds, no.

lofty idol
#

ah, good, cause I know the early access builds used to be outdated as all living hell

tranquil zenith
#

Looking for someone's immediate reaction/opinion with UE5's new LWC and world partition. Does the prospect of a 100x100km world (multiplayer) seem like a laughable, or more attainable matter to you?

TSR looks much improved in UE5-main

#

Way less ghosting and artifacts in the ThirdPersonTemplate when turning the camera around the player, and the lines in the template material are way less jaggy than they are on preview 2.

#

How can I speed up building UE5? It has taken hours now

#

It took almost 8 hours to reach one-fifth of the way there. And I have an alright computer.

#

Well, I have more ram than it is currently using, so it shouldn't be an issue.

cedar tree
#

yup, for example 32 GB for my 5950X wasn't enough

#

ran out of memory while compiling

heavy mango
#

Yeah I have more.

lofty idol
#

Disable anti virus, if you have >8 cores check ram as mentioned above.

#

My 4 year old laptop builds 5.0 in 3 hours (4 core i7 something).

#

Though to be fair, it builds the game project rather than the whole engine, never tried whole engine myself.

heavy mango
#

Even my browser almost uses more ram than visual studio. Its like they limit the amount of ram it uses?

hi, i have several questions about UE's build system:

  • there's a UnrealGame target, what is it here for? is it used in place of the custom {ProjectName}.Target.cs file we have? are modifications to GlobalDefinitions contained here applied to a shipping build of {ProjectName}.Target.cs?
  • when should you use TargetBuildEnvironment.Unique instead of TargetBuildEnvironment.Shared?
lofty idol
#

so... anyone run the latest ue5-main w/ nanite on windows 10 yet?

tranquil zenith
#

Extremely weird bug in the world partition overview where if you click the top options and try to move the viewport too quickly it causes the engine to lag so bad you have to restart the editor. Complexity of world doesn't matter. Works in blank world with nothing. Tried in preview 2 and 5.0 build and does the same thing

limpid light
#

Just a general observation that ue5-main branch seems unusually unstable lately.

lofty idol
#

non 10xx cards can run nanite with sm 6.6?

#

with windows 10?

#

if so, that's better, because it is nvidia shafting people rather than microsoft, but still...

limpid light
#

yes, I have a team member with a 3090 card on Win10 with no issues

#

According to wikipedia NV Kepler and above should support SM 6.6, but like I mentioned I clearly have issues with 10xx cards which are way newer than that. Could be a driver issue yeah

#

Weird, DX Caps shows my card as only being SM 6.5. I got a 3090 and on Win11.
Nevermind, was just an old version of DXcaps

golden mesa
#

Anyone tried changing the WorldGridMaterial in UE5? If I try to do anything to even a copy of it I can't save the changes. Im certain the copied file I made isnt locked by source control.
I made a duplicate of the WorldGrid, which works technically, but for some reason the file size is about a fifth of the WorldGrid. Ok... So I swap the WorldGrid file reference in my Engine.ini file to my copied version. And every texture is broken and I basically cant see anything. Super weird behavior

lofty idol
#

aside from crashing, it shows my 1080ti as 6.5, just like gpuz

#

Hopefully someday nvidia/amd will address it with drivers :/

limpid light
lofty idol
#

Yep, it's the latest one.

limpid light
#

So members of my team with the 10xx cards also see 6.5. Asking someone with a 3090 on Win10 to check what SM he sees

lofty idol
#

I hope at least Vulkan won't have this issue, but extension support on that one is even worse.

limpid light
#

Also another person with a Radeon RX580 also sees SM 6.5

chrome ingot

my 6800m is showing 6.6 as expected 🙂

what does this mean any why does it occur

# radiant pewter who compiled ue5-main, is there more fps than in 5.0? or there is no difference

I'm doing weekly builds of ue5-main, performance is somewhat better but that ultimately depends on which parts of the engine you're using. Also the major downside to ue5-main is that it isn't backwards compatible and isn't nearly as stable as the preview versions. So if you do decide to compile it just expect the engine to crash from time to time and your unsaved progress will be lost. Simply enabling some of the experimental plugins might cause it to crash upon open, so you'll have to edit your config files and disable the broken plugin if that happens.

#

In other words, it isn't worth it yet. Any performance differences will likely trickle down into the preview versions eventually.

eager hedge
#

over time ue5-main is more likely to have vast performance differences between versions anyway

#

perf doesn't just get better, there are going to be way more regressions in ue5-main compared to stabilization branches.

scenic mauve
#

Also an important thing to note is that Epic is literally updating ue5-main every work day. So the version you compile today, is already out of date within a few hours.

I can increase the resolution of my generated mesh x100 and use "World Position Offset", but that would fry the computer due to the extra vertices I'd have to calculate. The entire point was to generate a "low res" terrain mesh (1 meter per face or so), and use the texture's displacement map to give details.

cedar tree

hmm yea I suppose that does pose a problem, nanite requires offline number crunching right?

Those files are downloaded from Setup.bat, you can't find a specific commit for that probably.

Your best bet is going into Commit.gitdeps.xml file and opening Blame view in github, then find entries for those files.

do you have a reason to be using main over 5.0?

is EpicGames/5.0 the right branch to start tracking for release? just test porting over for now; ue5-main is already onto stuff that won't be ready until 5.1 right?

#

ah sorry see you just discussed that..

preview releases are tagged from 5.0 as well.

apparently this is the right command to find which branch a tag is from, I had left out the -a when first looking so it wasn't searching remotes:

I will probaly stick to the tagged preview releases instead of tracking tip of 5.0, just since there is probably more QA and more known issues going from one to the next than going from one random commit to the next

If you're using github look at the relevant folders and check history.

if you want to search commit messages, using a gui that supports it is probably the best way.

is there some step I'm missing to generate those?

it's more than just the NeuralNetwork package, though that shows up in half of them

#

huh, I guess these are all in intermediates, let me try nuking that and rebuilding

yup, nuking the BuildRules folders in Intermediates and running GenerateProjectFiles.bat again seems to have done... something... so it compiles again

austere cradle
#

\b is important, tells it to match at word boundaries (otherwise 'wind' finds tons of 'windows' commits)

that lists first commit line and then a stat summary of how many lines changed, there are some other options for shorter stat summaries; the main use is quickly eyeballing how big a commit was when you are looking for the recent significant commits that added a lot of features or changes

Why does the source build (5.0) randomly decide to recompile thousands of files...........

its done this three times

did you change anything?

nothing at all

not a single thing

what happens is..it crashes

#

then when I compile it goes through this..sometimes it does..sometimes it doesnt. there arent any files open and nothing has been changed

#

oh well

#

Its killing my grove though

chrome ingot
#

so you re running the editor/project through VS after compiling, it crashes, then you do it again?

tranquil zenith

I open vs..I compile..Im in the editor..it crashes..I compile it again. Is this not correct? I've always done it this way

after you compile, how do you open the editor and the project?

tranquil zenith
chrome ingot
#

that is fine, thats running it from the editor. Now is that for your project itself or just the engine?

tranquil zenith
#

the whole project

chrome ingot
#

when you compile, what do you compile? how do you do it

tranquil zenith
chrome ingot
#

definitely weird, it shouldnt need to recompile. Generally if you right click the project in the top right and build, it should build and be one and one until you make changes. maybe you are making some larger changes, but the engine shouldnt need to recompile

tranquil zenith
chrome ingot

try doing that, see if it builds. then immediately do it again

future reference to anyone who gets the following error when trying to build with vs2022 in shipping configuration:

I came across this msvc bug report: https://developercommunity.visualstudio.com/t/vs2022-1710-internal-compiler-error-when-building-1/1677086

which lead to changing the line[2350]:
for (int32 BlockIndex = FirstBlockIndex; BlockIndex <= LastBlockIndex; ++BlockIndex)
to:
for (size_t BlockIndex = FirstBlockIndex; BlockIndex <= LastBlockIndex; ++BlockIndex)

this has fixed the compiler error for me, hopefully anyone else who has searched for this issue well have luck with this solution as well.

...How the hell do you destroy an actor in world partition map...destroying it only 'unloads it'

#

..by which it can not be 'loaded' again..but decides it wants to show up when playing ...and I can't even edit its details lmao

#

I guess it's some bug. Recompiling temporarily 'fixes' it. Then it kind of just shows up again for a reason I can not make any sense of..and recompiling shows it is indeed destroyed and does not show up when playing...but then I'll mess around a bit in something totally unrelated, press play and boom its back

limpid light
#

Afaik there is no way to fully delete an actor in WP since its data is cooked into the cells. Even if you delete the actor, it will just re-appear when you move away far enough and then back to the same spot.

In essence, I'm not aware of any way for dynamic actors to be streamed in WP as the system is now.

finally we might have a way to make custom specifiers

static copper
#

yay

latent iris
#

So we'd be able to do our own U-style macros? Like LORASHLOVESBLENDER(true) and have it affect the prop/method?

eager hedge
#

Also, implementing a new U-macro would be quite a bit of work regardless. It's not something you just throw a few lines of code in for.

latent iris
#

Well that's what I was asking about with the custom specifiers. I know we don't know for sure.

eager hedge
#

Custom specifiers would be a far cry from full custom U-macros. The difference between adding a bit of metadata to classes and full blown code generation for types.

#

That's why I'm being very careful about saying what this is going to entail.

latent iris
#

Alright - so some C#-like attributes is more what you're referring to?

eager hedge
#

At a minimum that's what I'm hoping for.

latent iris
#

(Again - I know none of us actually know what this entails. Just speculation)

eager hedge
#

specifiers are just things like BlueprintReadWrite/EditAnywhere/etc. We can already do custom meta specifiers but those only exist in the editor.

And you can't (easily) generate further code from them.

not sure but I recently wanted to try new vehicle template around preview 2 tag commit and the vehicle flipped itself on the roof in about 3 seconds after startup 😅 But it was so obvious that I believe it must be fixed for the release.

Hello everyone

#

it is possible to have the same version Preview 2 as source on the git

#

I think the V5.0 est newer than the Preview 2

#

I also have a lot of bug, seem that the git version want to build my map in HLOD

#

and it crash all the time

novel tulip
#

Hello, does anyone know why I would be hitting this breakpoint in the code on UE5 preview 2?

#

// TODO: Should change to DiagnosticCheckNaN call, though that's only in Debug.
#if !(UE_BUILD_SHIPPING || UE_BUILD_TEST)
ensure(!Result->ContainsNaN());
#endif

#

My code compiles fine but when the editor starts up it hits this breakpoint.

#

The breakpoint is in UnrealMathSSE.cpp

#

<--never mind. I inserted the breakpoint by mistake, lol.

static copper
#

the versioning info is different

quaint kindle
#

ok ..

spring ocean
quaint kindle
#

I don't know why but the lastest version of UE5 git... it want to build the HLOD... there's something different if you look at the starter openworld map, it use HLOD for mountain

#

and the WP is only for flat surface

opaque phoenix

ok this is odd 5.0 has not being getting any commits but 5.1 is. Are we close to release?

welcome to the salt flats of Sweeney

limpid light
#
  • more WPO related commits shortly before that one
willow flame
#

Nice. Will be interesting to see how that cost scales with nanite having to evaluate so many more vertices.

limpid light
willow flame
#

Could be the start of the tessellation replacement we've all been waiting for though

limpid light
#

yeah and I'm curious if this happens post clustering, then we might get artifacts where WPO distorts the mesh too much since the nanite optimizations are kinda view dependent?

lofty idol
#

Makes sense for both VSM and Nanite.

limpid light
#

Sounds like an optimization to me

lofty idol
#

Sure, at the cost of disabling vertex movement in the distance. Fine for some scenes, not so much for others.

limpid light
#

I'd say fine for most scenes

willow flame
#

There's always the original non-nanite path ofc

#

It's always going to be a pick-your-poison scenario I think

lofty idol
#

Not if you want VSM. If you're not going to use any of that you might as well stay in UE4 imho.

#

Not that I think the sky is falling or anything, just a little bit disappointing.

torpid valve
#

all of it irrelevelant

#

where is DirectStorage ?

#

I know the API is here

#

but I want to enable it 😄

limpid light
#

I've been asking myself that for a while too iniside!

#

Epic talked quite a bit about that, over a year ago? Then just.. silence

torpid valve
#

yeah I remember when the first demo was "impossible" without erm nvme

#

turns out it's working fine

#

(the biggest drawback still being actor instancing in scene) 😄

lofty idol
#

Does directstorage matter that much though? It looks good on synthetic benchmarks but doesn't really improve a lot on real world scenarios from benchmarks I've seen. Am I missing something?

limpid light
#

There is only one PC game that has shown benchmarks (at GDC) and it was quite dramatic

torpid valve
#

it really depends the problem with Unreal are.. UObjects and espcially actors

#

which are extremly heavy to allocate

limpid light
#

sadly they didnt show the difference between non-DS and DS, but between normal HDD, SSD and nvme

torpid valve
#

if you have something like Entity System from Unity where allocating single static mesh is in margin of nano seconds

#

and you can allocathe 10's thousands per frame

#

DirectStorage would be dramatic improvment just for streaming the heavy part of entity like textures and meshes

#

in unreal you literally spend hundreds is microseconds just allocating single actor

#

aside from raw actor taking anywhere from 900 bytes to 1.5 kilobytes

#

it have to register with world, then it's components must register with world.. and owning actor

#

well tl;dr version, is this is crap

limpid light
#

DS will bring us: Faster load times, and yeah a dramatic improvement in what can be streamed in realtime

#

Loading a large WP map in editor takes ages now, I'm really hoping DS will help with that performance

torpid valve
#

also it should amke much more feasable to just load exactly what you see, which is not really happending now

#

Nanite Mesh is fully loaded or not loaded at all

willow flame
#

Man, SSD lifetimes are gonna be a lot shorter once games start launching on this new tech 😄

lofty idol
#

Double speed on an SSD looks nice, but it's literally a difference of 1 second vs 2 seconds in benchmarks, plus there's decompression to worry about too.

torpid valve
#

decompression is done on GPU

lofty idol
#

Not on PC from Microsoft's press release.

torpid valve
#

no

#

it's on GPU

lofty idol
#

"next on our roadmap." is their latest word on it.

torpid valve
#

nvidia and amd drivers support it

#

either way it doesn't matter

#

once it become standard CPU will probabaly get hardware support for it

#

it's not that dramatic new tech it's supported on Linux since like.. 8 years ?

#

(just without the heavy compression part)

lofty idol
#

Maybe I'm jaded, but it looks like the same situation as DirectX 10. Offers the world, but gives limited results, with the promise of getting more ubiquitous down the line. ¯_(ツ)_/¯

torpid valve
#

there is difference

limpid light
torpid valve
#

it's supported on consoles

limpid light
lofty idol
#

And what are the win32 stats? 5 seconds for SATA SSD?

#

Yes, on paper it looks nice, but isn't that literally a few seconds for loading?

limpid light
#

they were not shown unfortunately

lofty idol
#

3.2 seconds vs 4.1 seconds

limpid light
#

Have you been living under a rock? Have you not tried games on the new consoles? The load speeds are insane there

lofty idol
#

Is that because of the direct storage or SSD?

#

Because I've experienced the same difference after switching to an SSD a decade ago

limpid light
#

DS, or the console equivalent

willow flame
#

Consoles also have dedicated decompression hardware, or at least the PS5 does anyway

limpid light
#

MS version is "Velocity" and I cant remember the PS5 name for it

torpid valve
#

it's nowhere near comparable to switching for SSD

#

with current win32 api

#

you are limited to loading one-by-one

#

with new API you can crete "jobs" to load from multiple cells on SSD at once

#

the old API was done for spinning drive where linear access was the only access

willow flame
#

Also DS removes two layers of hardware transfer from the process SSD->CPU->RAM->CPU->GPU. With DS its just SSD->GPU right?

limpid light
#

But Terms is correct, we have yet to see an actual real world example of this that we can all try ourselves 🙂

torpid valve
#

Yeah, I want to see how it will work with Unreal

willow flame
#

I imagine that's going to have knock-on effects of freeing up CPU+RAM space too, not that they've really ever been bottlenecks tbh

torpid valve
#

right now im not convinced it will bring dramatic improvments

#

just not for the reason DS is bad

lofty idol
#

I don't really care for technicalities or situations where it'll be standard in 6-7 years. Looks to me there's bunch of hype but not much to show for in benchmarks. 1.1 seconds difference in a publicly released benchmark isn't enough to get me excited.

limpid light
#

MS says typical 20-40% CPU savings overall

willow flame
#

Nanite itself is pretty obviously bottlenecked by streaming performance

lofty idol
#

Tech seems neat, don't get me wrong though.

willow flame
#

Combine nanite with something like photogrammetry using all those unique textures, I think we'll see a lot of time invested into streaming tech in general

#

My (limited) understanding is GPU's have basically been laughing in the face of everything thrown at them for years, but it's getting it onto the GPU efficiently that's the struggle

limpid light
#

In the talk I linked above, MS says you need to program specifically for this and replacing Win32 IO calls directly with DS calls will in most cases be slower than it was before.

#

And yes, they confirm that decompression is on CPU for now but will come to GPU later

#

Its possible that Epic doesnt see enough benefit without that and are thus waiting

lofty idol
limpid light
#

hah possible 🙂

5.0 doesn't support direct storage on windows yet, right?

limpid light
#

not as far as we know

lofty idol
#

Why not windows 10?

Microsoft:

#

Sometimes there are actual reasons, often they are just thinly-veiled marketing pushes.

But I dont see a reason to make a fuzz? Win11 is perfectly fine and the easiest Windows upgrade I've ever done 😛

ashen kiln

Windows 11 is pretty stable with latest updates though

#

It's mostly no-brain update if your system supports it.

switch the toolbar to be left aligned and you hardly notice its not Win10 😛

Aside from metasounds, what else is there that isn't experimental?

maybe lwc is getting there, but that needs more time to cook

what is the issuemwith experimental ? ;p

i use most of the experimental stuff that there is

#

depends on what you do and how you do it.

#

experimental is a no-no for me, unless the feature is clearly going to be finished.

latent iris
#

I find that their "experimental" tag is often quite good.

lofty idol
#

network prediction was experimental and got quite the traction too...

#

🙂

latent iris
#

I really don't care all that much about that. There are plenty of things coming in UE5 that make it more than worth the upgrade even if you don't use the new fancy shmancy rendering stuff. It is completely dishonest to believe otherwise.

lofty idol
#

if you're going to resort to hyperboles I guess I'll just say different strokes for different folks 🤷

latent iris
#

Not a single hyperbole but w/e.

lofty idol
#

completely dishonest to believe otherwise.
Ok then 😄

latent iris
#

If you want to talk about hyperboles. But this is pointless. You do you.

unknown.png
lofty idol
#

Yes, because that is just one off statement that wasn't a part of a discussion. There's time and place for everything, if the guy you respond lists you features and gives you examples and you counter that with "completely dishonest" without adding anything to the discussion, what kind of response do you expect?

#

gasp I didn't expect you to indulge in such degeneracy Lorash!

#

Forward?

#

In UE5?!

#

😅

strong agate
#

The only skepticism I have with Nanite in forward is due to antialiasing. IIRC the main developer of Nanite said that it couldn't work with MSAA, at least at the time.

#

WPO is different, at the time he said that he didn't know how to approach the problem, but never said it was impossible. However with traditional MSAA it's a technical limitation, with one triangle per pixel I believe it would shimmer like crazy

solid cypress
#

What is your use case for data layers?

opaque phoenix
#

yeah @lofty idol

#

you have the option like you do in tick

#

For us VR devs thats huge as we depend on them a lot and we began hitting bottlenecks in our projects lately

#

overall I think ue5 might be nicer on the cpu even without the lumen nanite stuff (hopefully)

lofty idol
#

If only Fortnite would start to use Mass out of nowhere... 🙃

solid cypress
#

I am not sure if there is some AI branch/Restricted stuff but to me it looks like AI systems in main are not receiving that many changes lately

#

Anybody knows a reason for that?

#

Given how many new AI systems we are receiving I would expect higher activity for stuff like Mass/StateTree/ZoneGraph

torpid valve
#

afaik it's mostly done in private

#

i see most AI work on main is just "integrated" from different stream

solid cypress
#

I hope it will at least become some public P4 branch

lofty idol
#

Mass was made for the Matrix demo, now that the demo is out...

#

(I hope this isn't the case, but honestly I'm not seeing anything that points otherwise)

#

The AI team doesn't have the best track record when it comes to experimental plug ins. I seriously hope this will be the exception and gets more traction from Epic.

strong agate
#

Wasn't there some mentions of a Fortnite open world in the Apple lawsuit?

lofty idol
#

Open world is certainly a good case for ECS, but Fortnite itself is tied to the gameplay framework waay too tightly for ECS to become anything other than a simple crowd system.

#

Which can be a fine tool depending on your needs, just that it'll be a bit disappointing to not see ECS used to its full potential.

solid cypress
#

I do too, I would love to see AI systems have similar lifecycle as Niagara, Sequencer, Control Rig where they have stably assigned developers and there is just no "done" point after which it receives mostly just bug fixes.

lofty idol
#

Fortnite is going to have Verse too, a scripting language for modding, so Mass will need to compete (or complement) that one.

#

Plus there's the modular gameplay stuff that Fortnite is heavily using, which is all gameplay framework...

#

🥲

#

fingers crossed though!!!

Hello, does world partition work in network ? I compiled a server yesterday and when my client from editor connect to the server I saw a black screen, I could see my mouse pointer changing and see that it loading part of my project but the landscape is not there.... weird

limpid light
quaint kindle
#

what's the point to have wp then lol

#

this will slow down the game a lot

#

wp should be deal on the client side

willow flame
#

It can't

#

The server has to hold the authority state for all actors, otherwise how would a client know what condition the world is in in a given partition

limpid light
#

You can mitigate that with network relevancy ofc, so the actors that arent in range of any players are basically "sleeping"

quaint kindle
#

@willow flame ok that the server owns the map but WP client side loads the proxies it needs right?

#

The problem I have, when the client loads the level, there is no landscape being loaded in the Outliner.

limpid light
#

What version are you using? Landscape support was added quite late, for example it was not supported in Early Access

quaint kindle
#

I use the lastest version of UE5 on the git

#

I installed yesterday

limpid light
#

and you will only see things loaded in the outliner that are close to you, rest are HLOD generated grid cells

quaint kindle
#

v.5.0

limpid light
#

So you built the 5.0 branch on Git from source yourself? Then you should have practically the final 5.0 version yeah

quaint kindle
#

I see black screen, only a few thing is loaded not event the light is loaded

#

yes I build it myself and it work well

limpid light
#

sounds like a broken build? Try the Preview 2 version on the Epic launcher

quaint kindle
#

I could't compile it with the Preview 2 because you need the source for compiling server

limpid light
#

no idea what you mean there, you really only need the source if you are modifying the engine or need newer versions than are on the launcher

quaint kindle
#

I need the source folder

limpid light
#

In your scene, make sure your light and skydome are not marked as "Spatially loaded", but I believe they shouldnt be by deafult

View...view?

Well, some people love mvc

Good for them

torpid valve
#

Model - raw data from somewhere (like data base)
ViewModel - Adapter - converts data from Model to something which can be displayed in user facing way, like convert some ambigous double values to text, can also convert other way around from user inputs to something digestable by underlaying model
View - just display whatever ViewModel provides

#

Without some dedicated framework, this pattern is honestly quite usless

#

as the biggest gains are when you can dynamically bind ViewModel to View

#

so can have single viewmodel serving different view layouts

With the new one file per actor setup, I find it really hard to cherry pick / stage only the actors which I want to commit changes for because their file names are so random it's difficult to really figure out their identity beyond the scene they belong to.

Do you think there are any other ways around this currently?

Ahh okay thanks! I've not tried that yet. I'm using SourceTree 😅

If your using git, the git (beta) source control option in UE5 won't give you a proper Changelist. https://github.com/SRombauts/UE4GitPlugin There is a plugin for Git, not sure if it works with that, but it's also not available for UE5 yet.

New Unreal Tournament. Unreal Engine social accounts: 1st April - UT99 logo, 2nd April - UT 2k logo, today it has UT3 logo

#

Would fit the scenario. UT was kind of origin of UE

#

but it is all just crazy speculation 😁

#

But it can also be just UE logos. Tomorrow csn be UE4 logo and on tuesday it will be UE5

they will show Creative 2.0

that would be interesting but at the same time i always hate events they announce from the fortnite account hahah it leads to so many annoying people in chat but it did look interesting since they last showed it was basically going to be a mod editor on pc

"CitySample", that's gotta be the matrix thing

austere cradle
#

that's maybe the old ps5 unveil demo, it mentions an "entry cave shot" in one commit

#

and something mentioning "IterationProfile: Replace Reverb with AncientGame"

#

"Lyra" is another one mentioned

#

another "TheOrigin" (mentioned in above changelog too)

static copper
#

and "Frosty"

zealous yarrow
austere cradle
#

" Bulk-merge of Mass-related Frosty-side changes"

#

is "Mass" one too or is that a plugin or something?

#

oh I think that's a mass enemy thing right?

Added Mobility logic to the ISM Update and to Mass Mesh Descriptor

ah niice

it's used in the matrix demo for crowds and traffic

Fix for agent head meshes not replaying properly in Frosty sounds kind of matrixy, though of course there are mny other kinds of agent 😎

"agent" refers to a Mass entity that communicates with the regular gameplay framework

I think they mean that it will be much more stable

#

UE4 was pretty shaky for a few versions

torpid valve
#

Lyra - new game sample
CitySample, Frosty - matrix demo
TheOrigin - ?
Topaz - Ancient Demo
Rift - ? Guess something for Fornite.

lofty idol
#

Yeah Rift can be Creative 2.0 according to the name

#

Imagine if TheOrigin is a new UT 🤓

#

Anyways, only sample I wanna get my hands on is Lyra 😫

lofty idol
opaque phoenix
torpid valve
lofty idol
#

But idk tbh, the name just makes think it can be UT

#

I do not think it’s that since Lyra is focused on Shooter stuff

#

An equivalent to ShooterGame but using GAS, EnhancedInput etc

#

TheOrigin can just be a Lumen/Nanite sample showcase similar to the PS5 first demo

#

And +, Fortnite is kinda their new UT since a few years, this is clearly the project where they are experimenting stuff

lofty idol
#

All UT devs moved to Fortnite as of 2017/2018

#

So don’t hype you tooo much, State of Unreal can be just Tim talking about Creative 2.0 and what is planned for the future with Fortnite expansion and then talking about UE5 and follow on a Matrix Sample presentation

So the big things that are incomplete in UE5/are being developed on ue5-main: Pose Search (motion matching), Contextual animation, Strata, Lumen translucent material support, Chaos Cloth, Chaos Flesh, Mass, State Trees, Nanite programmable rasterizer (masked material support, some sort of wpo... Maybe) - What else am I missing?

lofty idol
torpid valve
#

missing: MVVM, asset virtualization, Horde,

#

Chaos Cloth is probabaly most polished of all those 😄

#

Does someone know what samples are on p4 atm except Lyra ?

torpid valve
#

nothing new

lofty idol
#

hm

torpid valve
#

everything else is on private streams or /restricted

gilded pecan
torpid valve
#

yes but that system is abouut enviromental awernes

gilded pecan
#

Example: In the Echo in the Valley of Nanite demo, when she places her hand on the door frame. To do that with motion matching, you would have to add temporal elements, like they did with UE3 or TLOU2

torpid valve
#

motion matching is just database to search for specific criteria

#

and I'm now like 99% suure

#

it's going to be enhanced with machine learning

#

since they hired the main researche of all those fancy ML animations from Ubisoft ;d

gilded pecan
#

That would be Motion Synthesis.

#

But regardless of the implementation, to be able to target specific poses contextually, Pose Search will need a system that targets a specific pose, in a specific place, in a specific number of frames.

#

To recreate the Echo in the Valley of Nanite with pose search, it would involve calculating the player trajectory, seeing if it hits any "contextual trigger volumes" -> placing a given target pose frame (Echo touching the door frame for example) on the trajectory at the intersection point -> searching through the possibility space to grab the correct frames to transition to that pose.

#

So some sort of "contextual animation" system would still be needed 😅 . /rant

torpid valve
#

for me it sounds like more complex cover system

#

with more detailed enviromental awerness

#

well

#

if I get the enviermental awerness part in form of plugin

#

I wont complain : D

marble sedge
#

Maybe a stupid question, but why does Epic want implement its own CIS for UE?

oak pilot
#

Heaps of reasons they might want to. P4 is expensive, they might feel they have a solution that's more fit for purpose due to project scale and/or usage patterns, in general they seem to be building more and more of an ecosystem they own and control, and that's one more piece of the puzzle.

#

So cost, technical and/or business development reasons

#

Narrowing down which reason will depend on what they release if they are intending to release something

#

There's been only references spotted in code afaik. So there is no guarantee anything is coming

marble sedge
#

Just speculation, since building and testing are most done on cloud computers, maybe Epic want to extend its Online Services to more than hosting & shipping games

torpid valve
# 
**Horde** is a scalable, cloud-ready, distributed build framework and content-addressable storage platform 
designed for Unreal Engine. 

Goals of the project include:

* Remote execution of arbitrary workloads, including compilation of source code and building assets (like SN-DBS, 
  FastBuild, IncrediBuild et al).
* Storage of bulk data for source assets.
* Caching of assets and build artifacts through Unreal Engine's DDC system.
* Storage for final build artifacts (eg. packaged builds).
* Replication of data between studios on a planet scale.
* A CI/CD system for teams to test, build and publish their projects.
#

most of it is not implemented in available code

#

but Horde is more like cloud extension of Unreal Editor

#

dreamy warren
# strong agate In an IGN interview Epic said that they wanted run UE5 on the cloud, specially f...

If they want to make that transition with minimal changes to the engine itself, they might end up creating something like Paperspace (low latency desktop streaming) and build on top of that platform. They could even have the editor state replicated client-side and only stream the viewport proper. This is one direction I expect Unreal Engine to take by the time 6.0 is released.
In the meantime, we might see pure desktop and cloud versions of the engine coexist, much like with Adobe's Creative Cloud

strong agate
#

Doesn't something similar already exist with pixel streaming? Like, metahuman is already running UE.

dreamy warren
#

From a performance, UX or business standpoint ?

#

The real question is whether or not that'll still be the state of affairs 8-10 years from now.

latent iris
#

I'm with Lorash on this.

dreamy warren
#

Leaving ever-increasing players expectations aside for a moment, UE has become less and less greedy in resources for any given workload and hardware has kept improving there has to be some point where those two curves meet

dreamy warren
latent iris
#

I'll use Unity before I use an engine designed to be used from the Cloud.

dreamy warren
latent iris
#

Then I'll just go back to Godot.

#

I ain't usin' no darn engine from the cloud.

dreamy warren
#

I think that's actually the strongest argument against my theory so far

strong agate
#

I don't think SaaSS for developers will go anywhere anytime soon, developers usually are in the end of the spectrum, developers value time. And it's pretty common for folks here to have 64gb of Ram, 3080-3070 and a 5900X. Running an instance with similiar specs on a cloud would be extremely expensive.

#

I don't think their solution will be the fully fledged editor. I think it would be more of a sandbox and a learning tool for kids from Fortnite creative.

#

"The new cloud-based platform, Pitalwalla tells me, involves daily training of Unreal Engine essentials. It’s still in its early stages, however, and the company is yet to roll it out to all regions at scale."

#

More people on your ecosystem the better

#

But yeah, I can see a cloud version being pushed to prosumers and beginners. Photoshop has a cloud version even. However in our spectrum our usage is pretty demanding. So if everything goes cloud I believe developers would be the last case the companies would worry about.

#

And we don't have anywhere near the problems companies face with hacking or piracy that would motivate them to put their games on cloud only

#

Vray already has a service like that. I personally would pay for something similar.

I know this is a git question, but I wonder if anyone here knows the answer.

Now every time they pull, they have to manually git lfs pull every time.

What is the way to reverse that initial command, does anyone know?

@desert oxide not sure but it's probably set somewhere in the config in the .git directory or in the user's ~/.gitconfig

Looks like it writes the config into the user's global config by default

you can probably just do git lfs install --force to overwrite it

#

how do you migrate an older ue5 project to the official version?

umbral tundra
#

I believe you simply launch it through the new editor version and it prompts you to upgrade.

#

Does anyone know why the code of the ue5-main branch still isn't the same as the newly released 5.0 version? Are there simply still experimental features in it?

proper hearth
#

Main will turn into 5.1 eventually

umbral tundra
#

I was just about to say that I also found an explanation on the Github xD

Most active development on UE5 happens in the ue5-main branch. This branch reflects the cutting edge of the engine and may be buggy — it may not even compile. We make it available for battle-hardened developers eager to test new features or work in lock-step with us.

If you choose to work in this branch, be aware that it is likely to be ahead of the branches for the current official release and the next upcoming release. Therefore, content and code that you create to work with the ue5-main branch may not be compatible with public releases until we create a new branch directly from ue5-main for a future official release.

proper hearth
#

the release branch in github will point at 5.0 (plus hotfixes) until 5.1 releases, but if you're on main you'll get the latest (probably broken) code

#

I would not recommend using main at all any more, they'll move the critical fixes into 5.0.1 or whatever

umbral tundra
#

I was hoping for a specific thing in the ue5-main branch to come with this release, but it didn't make it in 😦

#

Thanks for the answer though 👍

dry halo
umbral tundra
#

In my case I really would have loved getting something from the main branch on the current release, but considering I quite literally don't have the disk space to get a source build I'll just have to wait until I can get a new SSD in my PC. That's why I was hoping for the new release to have it, but oh well 😛

If you figure that out let me know, been asking for a "Download Plugin" button for at least 5 years.

If you have enough space, a shitty workaround is to install the appropriate engine version and then symlink the plugin folder to your source build
