early 2021
hollow ore
For alpha testing
half panther
full release late 2021
sweet relic
@fierce forge yup, retroactive to Jan 1st 2020
hollow ore
@wary ferry my project scope just changed massivelu
wary ferry
oh god i am so fucking emotional, have to do LOD and optimiziation for the next year and then it just goes away 😉
hollow ore
F thst
fierce forge
from jan 1st 2020 is 1milion ? @sweet relic
hollow ore
That
wary ferry
I hope it allows for sandbox games
wet brook
it does
half panther
yep
sweet relic
@fierce forge correct
hollow ore
Yes
half panther
you mean voxel games @wary ferry ?
wary ferry
i mean even if it would be just conan exiles for example
half panther
terrain manipulation you mean?
hollow ore
@fierce forge so if you make a game today and put it on epic game store and it never earns $1,000,000 you NEVER have to pay anything
wary ferry
yes, that too 😄
fierce forge
also on steam right ? @hollow ore
wary ferry
but mainly, sandbox games have many issues with polycount
and without that restriction
we will enter a new era
hollow ore
Yes but steam will still charge you
half panther
id doubt they will implement a voxel system from the beginning on

Does UE5 rid off NV ray tracing?
gentle solstice
No need for it
😂
Well, actually, I wonder how they're handling things like reflections
half panther
do you think there will be a marketplace sale?
i would have expected one before the announcement because now that ue5 is coming people will buy less
at least for a while
gentle solstice
Hope they don't revert this technology like they did with UE4
wary ferry
?
plush yew
The video said "Nanite achieves detail down to the pixel." So they are capping the renderer to only render triangles the size of pixels @plush yew @mint raptor so i doubt its actually doing a lossless compression anyhow.
Unless you're running at 40k screen res, i dont see how it could be lossless
grim ore
why....are...people....doing....that...with...ue4. UE4 is still valid, UE4 is not going anywhere, using UE4 now will prepare you for UE5. Assets bought on the Marketplace for UE4 should work fine in UE5.
gentle solstice
The original UE4 reveal showed voxel and fully dynamic light based, but then they realized next gen consoles were too shit, so they reverted to baked lighting, which is the UE4 we received.
wary ferry
yeah but they will be worthless in terms of quality mathew
half panther
yes, assets. but there are also other things on the marketplace
open star
just saw the video and all i can think of 'when are we getting an mmo with that tech'
woeful bobcat
Next gen consoles are shit?
gentle solstice
Well, not every game is necessarily gonna go for a 3TB install size off the bat..
wary ferry
i mean i work currently on packs and i think ... meh maybe i dont sell them now and just make the high polys for later on
feral mirage
@wary ferry There will be plenty of people not looking to go for realistic
grim ore
buying assets now do not invalidate them. You are not suddently going to make a 10GB game for an ios phone
wary ferry
definitly - stylized will always have a place 😄
grim ore
8k textures not does not make them shit in the future
gentle solstice
@woeful bobcat PS4 and XBOne
wary ferry
true!
gentle solstice
Well, the new are pretty shit too, relatively
wary ferry
i always forget that there are non desktop games 😄
gentle solstice
It's not even out, and first gameplay reveal is 30fps
plush yew
@grim ore Substance painter needs to get on that!, Shitting textures for the win
next badger
i'd love to make non realistic game but with realtime GI...thing Epic promised years ago
wary ferry
i am pretty sure in that res you can use vertex colors xD
grim ore
Starting a project now to learn Unreal Engine (not 4, not 5, just learning Unreal Engine) by using UE4 and transitioning to 5 is smart
gentle solstice
At least they're going with the same free for everyone license as UE4. Just better.
wary ferry
thats true mathew 😄
but man its so hard to wait now 😄
I hope they offer a good way to transition from 4 to 5
thick herald
They said UE5 will take the high def assets and scale them down for mobile etc, though
grim ore
that's the plan according to what they have said
half panther
project? yes
kindred crag
Doesn't UE4 already have an automated LOD system? How is that different in UE5? 🤔
wary ferry
Do you think that nanite will remove the need for world composition?
rigid belfry
there is no way this will be free
kindred crag
this should be free
rigid belfry
its literally the holy grail of game engines
plush yew
Any idea of entry level pc specs ue5 amd
kindred crag
Oh I see
gentle solstice
Well, considering they're porting Fortnite to UE5, and forward compatibility was a big focus, so porting should be straight forward
plush yew
any idea why my third person characters dont hold the gun right an dont do the reload animation.. but the 1st person view it does...
half panther
what specs do you have @plush yew
gentle solstice
@kindred crag There's no LOD system in UE5 at all. Not in the LOD kind of sense. Basically, the engine now creates billions of LODs on the fly (that is, it doesn't at all)
feral mirage
@rigid belfry I don't believe they will charge for it
wary ferry
entry level specs should be comparable to ps5
Do you think that nanite will remove the need for world composition? @grim ore
woeful bobcat
consoles will release more exclusive games.
plush yew
Not good enough i5 med rang with a 950gtx but I been waiting before I upgrade
grim ore
@wary ferry I would assume no as you still have the entire "floating point" issue with large worlds that has to be accounted for some how
plush yew
"This isn't noise. These are the triangles, each a different color. Most so small they look like noise, Nanite achieves detail down to the pixel."
Wait wait isnt that just a fancy way to say it's noise?
gentle solstice
They probably have some kind of optimization technique for storing large quality stuff
plush yew
ugh.
next badger
@plush yew my guess is replication, which one is server?
kindred crag
@gentle solstice Thats reallly fucking insane holy shit
wait whats this nanite thing im hearing
half panther
@plush yew youll at least need a 1060 id guess, but id go with somewhat better
hollow ore
I'm not against Unity, I think it has it's uses, but there is definitely an uprising occurring there today 👀
grim ore
@plush yew first person and third person are using different animations?
gentle solstice
You'll never see pop-in ever again
plush yew
So vr entry should cover me
gentle solstice
In UE5 games anyway
plush yew
yes they are
kindred crag
whats nanite? 
gentle solstice
UE5 is gonna be amazing for VR
half panther
i wouldnt be too sure
wary ferry
UE5 WHEN??? xD
kindred crag
lol aight
gentle solstice
Early 2021
wary ferry
not soon enough!
plush yew
doesnt matter which character i use they all dont
wary ferry
NOT SOON ENOUGH (ok i have to dip out bye)
grim ore
all of this virtual meshing and no loading and such is great but uh.... you guys know this is on consoles with the new HDD technology, not on your slow sata drives
half panther
but if i was at your position id look into buying a new pc straight away, i dont know if you will be able to keep many parts
grim ore
PC's are not magically going to get faster loading, the consoles designed their drives like that

an SSD is not a FAST SSD, nvme and sata are not the same

Things in "Developers" folder doesn't carry over to release builds right? So technically I can do all my stuff in Developers folder like maps etc as a test environment and then put them in the Content folder like normal later when "finished"?

grim ore
the new console drives are not even close to most peoples drives in their home machines, they have decicated chips just for managing them for example
mint raptor
@plush yew Lossless might be a matter of perspective? Information is lost as a matter of distance. Like trying to see the atoms of my desk from this far is impossible but the information isn't lost, it is still lossless no? Maybe just semantics...
gentle solstice
Imagine gaming news in a couple of years. "Red Dead Redemption 3 file size has been revealed. 722 TB"
Nothing. It's just SSD
plush yew
@plush yew Lossless might be a matter of perspective? Information is lost as a matter of distance. Like trying to see the atoms of my desk from this far is impossible but the information isn't lost, it is still lossless no? Maybe just semantics...
@mint raptor But if the object has lots of detail in a single pixel all is lost to a single triangle. Thats what i was trying to say.
Probably good to lose all the data in the pixel because hey its the size of a pixel, but it might be something to look for
dense aurora
when was UE3 released ?
mint raptor
PS5 using an NVME?
grim ore
dedicated hardware for file io and compression
gentle solstice
They're claiming the PS5 SSD is "up to" 5GB/s
mint raptor
Loading screens for classic games that is lol
now with Nanite
Loading screens are 10x longer
gentle solstice
Well, if the PS5's SSD is the secret to this demo, they should probably have mentioned that UE5 is PS5 exclusive
next badger
@plush yew 5GBs of data in a single second. That's 2GBs in 0.27 second
Math?
grim ore
this tech is not exclusive to the ps5, the series x will have it as well
gentle solstice
If the technology that basically sells UE5 requires that kind of data transfer, that's false advertising.
half panther
ps5 wont be cheap i guess
grim ore
and it helps, its not required just saying dont expect the same results on your home machine
wary wave
Series X does not have remotely the same capabilities as the PS5
mint raptor
Supposedly this will all work on current hardware
next badger
afaik Intel Optane is the fastest SSD now
modern socket
@half panther I think it will be around $445 range...They make money through online etc. So it wont be crazy
gentle solstice
Well, Epic confirms the PS5 is what makes it possible, but that it will run run in real time on all next gen systems 🤔
Sounds kinda contradicting
wary wave
there's no equivalent to what the PS5 is using in the PC space yet either
modern socket
Series X will run better, but PS5 has a wayyy better SSD
mint raptor
Also Nanite should just be an algorithm that runs off a loaded texture no need to Load in more textures for nanite to work. Sorry model not texture...
next badger
thta demo is not even 60fps

the demo is 1080-1440p and 30fps

Naa Optane is pants

[The PS5] puts a vast amount of flash memory very, very close to the processor,” says Sweeney. “So much that it really fundamentally changes the trade-offs that games can make and stream in. And that’s absolutely critical to this kind of demo,” Sweeney explained.
grim ore
raw power isnt always an answer, its like saying my CPU is a billion GHZ so It should be able to decode video as well as my gpu
dedicated hardware is a thing
plush yew
@grim ore what is the floating point issue?
gentle solstice
“This is not just a whole lot of polygons and memory. It’s also a lot of polygons being loaded every frame as you walk around through the environment and this sort of detail you don’t see in the world would absolutely not be possible at any scale without these breakthroughs that Sony’s made.”
next badger
but RAW power of GPU is proportional to speed triangles are rasterized
modern socket
When we getting PS5 level SSD's lmfao...
grim ore
@plush yew floating point numbers have limits for being accurate, its why world comp exists. You cant just be a hundred billion billion units away from center and have your physics and data be accurate right now.
gentle solstice
So basically, UE5 is PS5 exclusive. Considering "not possible without Sony's tech", and we all know Sony's stance on exclusivity
kindred crag
grim ore
thats also saying stuff like UE4 is PC exclusive just because you can do RT on a PC but not on consoles with UE4. different platforms will have different experiences
plush yew
Shouldn't it still work for other things lol
kindred crag
UE5 will also be free though right?
wary wave
UE5 does support other platforms; it's the extent of that demo other platforms will struggle with
gentle solstice
@plush yew Hence "contradicting"
Well, if other platforms will struggle with what they showcased, then they shouldn't have pitched that as the high point of UE5
modern socket
I mean, Q3/4 this year PS5 and Xbox Series X will already be outdated...I doubt it's PS5 exclusive or runs better on PS5
grim ore
well they demod the star wars RTX demo on UE4 so might as well bitch about that not being possible on xbox one
plush yew
Lets say its meant to run on a SSD , with an 8 core cpu with 16 gigs of ram and like an rtx 2080? you are probably looking at somewhere at 500 to 600 GB Bandwidth of data bottlenecked by the SSD, so real talk we are hardware limited at this point i think.
wary wave
PCs will catch up given a little time, it's just the XBox that's the limiting factor
thick herald
so much salt, after a teaser trailler 😄

there are already games out there with different experience on UE4 on consoles and PC. the new star wars jedi game had loading issues on base xbox one

I'm wondering is there heavy math behind this NANITE stuff

oh no, it's basic algebra

nah the entire engine uses magic and unicorn farts

its just basic addition and substraction
next badger
@plush yew hyped, but skeptic
plush yew
^ It is just addition and subtraction, everything in math unrolls into either.
next badger
PhD -> Doctor of Philosophy?
summer turret
they just substract 80% from whatever the polygon count is and boom
thick herald
I thought everyone knew nanites aren't very heavy
urban gyro
You know, despite the awesome UE5 stuff, I consider the Epic Online Service to be a much bigger announcment
gentle solstice
@summer turret Well, technically computers can only add. Subtraction, multiplication and division is all done using addition

it's available, that's pretty new about it

most of the bugs are caught by the comunity tho

yes, I but the "community" is not getting paid for bug testing so...

feral mirage
@lament star they are not charging you to test it either..

@kindred crag it has its issues
urban gyro
yeah, it should be a blinding white tint

Does anybody know if Nanite is based on mesh shaders? I see no other way but that'd restrict the target devices a lot
lament star
@feral mirage what? If you use the engine and stumble upon bugs it's not testing
fiery wind
Cryengine ui is good i think they do something like that
kindred crag
the node graph editor, the pins are too small
Okay that I agree
lament star
@tulip pine it must be
tulip pine
I mean I assume literally no-one outside the core team has technical knowledge at this point but worth a shot
feral mirage
@lament star My point is a engine as complex as these will never be bugfree just won't happen. You don't have to pay for the engine and they are active on fixing bugs with each release. Not sure how you want more.
urban gyro
plus its open source, so u can fix it urself 😛
tulip pine
I dream of the day when I can reliably assume all players to have hardware that supports mesh shaders
plush yew
@tulip pine I suspect it's not, but rather a cpu or gpu algorithm that progressively compresses and uncompresses the original model to fit triangles to pixel or larger size.
lament star
@feral mirage You can pay people to test your software and report bugs before releasing it
tulip pine
a CPU algorithm sounds awfully slow
gentle solstice
@tulip pine Not really
tulip pine
doubtful of even a GPU one without mesh shaders
night bridge
did you guys also hear about Unreal Engine 5?
modern socket
So basically UE5 is basically UE4.5?
urban gyro
basically
lament star
@modern socket looks like it

They mentioned the demo scene has hundreds of billions of triangles, there's no way a CPU is going to crunch over that in real-time without sacrificing an enormous amount of resources
feral mirage
@plush yew it's 5% after a million which 99% of indies never reach now.
brave gate
yes, I but the "community" is not getting paid for bug testing so...
@lament star seriously? we got indie-to-AAA engine, no subscription or royalty until making first million dollar on game and publicly accessible source code...
and people still use phrase "we're not getting paid for bug testing"?
feral mirage
My point is just this is a very complex engine which get's more complex with each update and which brings in more potential bugs just will never catch them all.
brave gate
what's wrong with humanity? 😛
plush yew
They mentioned the demo scene has hundreds of billions of triangles, there's no way a CPU is going to crunch over that in real-time without sacrificing an enormous amount of resources
@tulip pine You highly underestimate programmers. No one thought neural networks would ever be computationally effective and stored on a shelf for years.
something similar could have happened with progressive geometric compression
lament star
@brave gate you'd know
eager coyote
My question about UE5 is regarding that polycount stuff. Do you think what they were saying about allowing absurdly high polycount and straight from model software stuff was exaggeration? Because if not, some crazy stuff becomes possible
tulip pine
I'm a programmer too 🤔 My hardware is largely outdated yes but I don't see that happening
gentle solstice
@tulip pine Well, you never know what they can do with algorithms. This ran at 20 fps purely on CPU 10 years ago https://youtu.be/00gAbgBu8R4?t=153

ah yeah seen that before
urban gyro
Euclideon tho
brave gate
but Euclideon was never released?
urban gyro
it was afaik, it just ended up being a local hologram thing
brave gate
wow, sad
urban gyro
i think they used OMNI for controls and their holo-tech out of it
gentle solstice
@plush yew Wrong. 1950s
plush yew
Don't knock it, it is impressive but only if your scene is repetitive, like a forest with trees and rocks, or is tile-able like minecraft.
other than that it sucked for animation. it needed to be a hybrid system and they refused and animation support was lacking
@plush yew True, but only until recently they have had a resurgence because of accessable hardware
dry moon
One of the programmers for Epic, Brian Karis, has a blog about it from 2009. It kinda goes into detail though in 11 years much has evolved. https://graphicrants.blogspot.com/search?updated-max=2009-02-25T18:24:00-06:00&max-results=10
Biggest take away I think is this part
I do like this format better than subd meshes with displacement maps but it's still not ideal. Tiny triangles start to lose the benefits of rasterization. There will be overdraw and triangles missing the center of pixels. More important I think is that it doesn't handle all geometry well, so it doesn't give the advantage of telling your artists they can make any model and place it however they want and it will have no impact on the performance of the game. Once they start making trees or fences you might as well go back to how they used to work because this scheme will run even slower than the old way. The same can be said for subd meshes btw.
lament star
I whish they showed more of the water simulation in the tech demo, they quickly panned the camera over it
urban gyro
to be honest that simulation didn't look that mindblowing
gentle solstice
Was pretty shit
feral mirage
yea the fluid simulation needs alot of work
urban gyro
just a puddle, if it was a river
lament star
yeah, it looked like regular render target stuff
that's why I wanted to figure what's new with that
gentle solstice
Also, I don't think it was fluid simulation. To me, fluid simulation implies they'd be able to turn the canyon on its side and it would run "up" the walls
thick herald
looked like Marvel Masters water
urban gyro
they might be trying to replicate FleX
next badger
@dry moon i have to agree that triangle of size of the pixel is bad in terms of quad overdraw
gentle solstice
@plush yew Pretty sure that "efficency" was like 6 fps
dry moon
Maybe they solved some issues in those years, who knows
but we can kinda get an idea that it won't be a solution for everything, especially foliage
feral mirage
Fluid simulation is one thing I am looking forward to being better in games, even though it s a small feature for most games it would be some awesome touches for like if it's raining etc.. but we are headed that way one day
urban gyro
small feature? blood is a fluid you know
next badger
water is probably the one from niagara that Ryan Brucks showed
https://www.youtube.com/watch?v=WTABH-f8rbE

may be wrong

analog magnet
quick question: if i switch unreal version of a project, is it normal for it to get stuck at "initializing" 39 or 45%? i've read online that it has somthing to do with recalculating shaders? there are some "ShaderCompilerWorker" running...
thick herald
yes
gentle solstice
@analog magnet Yes. Recompiling shaders can take like an hour
analog magnet
so i should just wait?
thick herald
yup
analog magnet
okay, thank you guys
plush yew
@dry moon nice, i read a bit and seen he's read Progressive Buffers and from him "Progressive Buffers is one of my favorite papers. It's one that I keep coming back to time and time again."
Which is really cool, because that paper is not the same paper i thought the tech to be, but its the same idea, but where it's view dependent. which obviously makes sense for a game engine.
eager coyote
I think if they didn’t focus on it, it’s not going to be that impressive. I think the polycount stuff is the real game changer IF true. You could simplify workflow hugely if that stuff holds up and you can take a scanned model or complex creation and just put it right in
urban gyro
thats the idea isnt it
analog magnet
ah, just finished this moment...
urban gyro
i mean they dumped quixel assets from film
so i suspect thats the intended use
scan plug n play
lament star
@eager coyote I don't think they'd lie like that
gentle solstice
Does it apply to non-static geometry like the player, though? Or does the player need to be "low poly"? 🤔
dry moon
Yeah and I would assume since they have more control over polygons, they might be able to cull polygons as well kinda like Call of Duty does?
but that's just a wild assumption
eager coyote
Not lie, but exaggerate effectiveness. Like yeah in motion is the big question
urban gyro
chaos sims are dynamic objects right?
lament star
wdym?
kindred crag
I hope with UE5 you dont have to manually texture everything once you import a model, even Unity has a better system in place
plush yew
No i think they probably can cull polys, we might even have settings we can mess with to change the power or whatever
gentle solstice
Well, no doubt it works for moving objects. I meant more like skinnable meshes. Like bone animation
urban gyro
i mean if the chaos objects in the demo are dynamic, then this massive polycount will be fine for non static meshes, including chars. at least logically.
plush yew
@gentle solstice In the Progressive Buffer paper i linked above in the summary it says this
"Deformable models. Although we have not implemented
progressive buffers for deformable models, our approach can
be adapted to such a setting."
urban gyro
it would be pretty lame if only for static
gentle solstice
@urban gyro Well, not necessarily. The engine needs to move all the polygons of skinnable meshes, so that'd be the work, not the rendering itself
urban gyro
i mean i don't understand why it wouldn't work for skinned meshes
lament star
Chaos? @urban gyro
urban gyro
objects driven by the physics

lament star
It took a team of a couple dozen people to make that tech demo in about 6 months
gentle solstice
Didn't read much about the online service thing. Does this mean we can make games for free and have free master servers?
urban gyro
dunno bout servers but friends achievs matchmaking etc

we still have to do servers ourselves
but it gives us achievements, p2p stuff and friends and all that you would expect from steam and other platforms
but its universal
urban gyro
im rly curious if can integrate with steam without steamworks
gentle solstice
I meant master servers. IE server list
tribal kayak
not sure myself
gentle solstice
Sounds weird if they provide match making but not master servers 🤔
plush yew
If its doing matchmaking and friends id imagine we can get master servers
next badger
for free for use with all engines, all stores, and all account services.
So, can we use it with Steam?
urban gyro
u asking about getting a list or hosting a server
@next badger thats what it says on the tin, even steam logo there
plush yew
Whats an ecs
gentle solstice
Entity Component System
urban gyro
composition stuff
plush yew
it probably is a master server, where it hosts a published game's on epics game store to be honest, and if thats the case im all for it, we need more than just steam. competition drives innovation
urban gyro
sometimes inheritance is a pain
gentle solstice
inheritance can be downright counterproductive
urban gyro
well, so can composition 😄
plush yew
got to it first lol.
knowing when to use the right tool is the best advice,
dont use a butter knife to cut wood,
Would love to be able to put my game on both and have them interconnected
urban gyro
from what I can see in the docs, thats what u get
plush yew
Ok thats a bit unreal
lament star
UE5 is trending on twitter
plush yew
you can 😄 it's called Composition over inheritance i think?
But the idea im thinking of is, use composition for the reusable parts and inheritance when you need to or it makes sense to
urban gyro
make sure not to get fanatical and make atoms when u just need a box

inb4 the unity crowd joins the discord
gentle solstice
Sometimes the journey is what matters
plush yew
i met a "software dev" at work once, he got fired for stealing software, but he copy pasted every stackoverflow bug answer into our code base then proceeded to copy and paste that same code base into his own github lol.
hollow ore
@urban gyro the unity crowd is staging an uprising right now
urban gyro
srsly?
hollow ore
They are all pretty upset.
urban gyro
nah
hollow ore
Unity is good for what it's good for but they are still charging people to use it
plush yew
Yep, woulda been fine if he didn't copy the entire thing into his github, copy and paste is fine, normally, but be careful because what content you copy and paste, it can sometimes be licensed code lol
urban gyro
bp is ur c#
gentle solstice
@hollow ore Unity is free for everyone. They take royalties like Unreal
next badger
UBT uses C#...no one stops you
wild kestrel
@next badger you can not use C# to make actually game code, not with raw UE4
gentle solstice
@plush yew That's a different issue entirely
rain saddle
imaginw if i had hardware that could actually run unreal at more than 10 fps
hollow ore
@plush yew absolutely
next badger
@wild kestrel well, i have not said you can...i've just meantioned that C# is used by ue4 to generate some c++ code...so it's possible...super hard but possible =))
gentle solstice
The only thing Unity has over Unreal, ignoring third party stuff, is C#
urban gyro
I still think lots of Unity users gonna jump ship in the next few months
gentle solstice
@next badger That's some baaad logic
urban gyro
C# tho
gentle solstice
@plush yew GTFO
frail sail
at ue5 the blueprint full nativization support will back again? 
next badger
C# is...um...
plush yew
Wow Valve and ATi were the two behind Progressive Buffers! WOW
urban gyro
ue5 will have a c# wrapper for the bp wrapper, all of it will be wrapped by beef
wild kestrel
@next badger UBT only manages build process, the ocde is generated by UnrealHeaderTool which is written in C++
plush yew
Let that name sink in, ATi.
gentle solstice
@plush yew You must have been living under a rock...
abstract relic
C# is absolute crap for game development. Stick to web development for that.
next badger
@wild kestrel my bad, you right...but it uses c# to generate c++
fierce forge
how i can resolve this problem ? when i'm in front of the sun the grass is dark and if i'm not it is not dark
normal burrow
i have to agree c# is an absolute nightmare to use properly, and to use it improperly is ill-advised. not suited for games at all.
plush yew
ue5 might use ecs for all we know. there were a few commits about entities in the past, they also bought out the skookumscript guys, they are still working at epic
wild kestrel
No, UHT generates the code, UBT just runs programs in specific sequence
plush yew
You shouldnt use the wrong tool from the job, i thought i covered this,
urban gyro
dude im joking lol
next badger
@fierce forge it's totally fine...your grass in not SSS (try other shading model in grass material)
normal burrow
funny stuff
plush yew
python and c++ is the name of the game
@urban gyro Yes please, maybe a touch of cython too ❤️
frail sail
at ue5 the blueprint full nativization support will back again?
Guess no
next badger
@plush yew Java runs on virtual machine...c# is more performant in most of the cases
plush yew
Blueprints run on a virtual machine 🙂
wild kestrel
Yea C# is faster then Java
next badger
if ECS in ue5 is not a lie...BPs can work way much faster
urban gyro
u can nativize bp tho at deployment, messy stuff tho
plush yew
Python is mainly written in C. so its an easier time. plus there are languages like cython which is python, but get compiled into c then compiled
fierce forge
@next badger i tried but nothing
normal burrow
the way most people write c# is not performant at all, because if you want performance you have to implement many many interfaces and sometimes explicitly so
both java and c# have the issue of being horrible at low effort performance, where they don't really hold a candle to js or python written in seconds
next badger
well, c# was written for usability, not performance 🙂
normal burrow
wouldn't want to use any of these for game runtime of course
plush yew
@next badger It shows
normal burrow
yeah and it fails at usability imo
plush yew
^
normal burrow
if i want to put something as a key in a dictionary on c#
well, i'll not go into that nightmare
plush yew
in python its as simple as bro["imakey"] = None
gentle solstice
You're clearly all insane here..
urban gyro
theres useful stuff there tho, stacks and queues are handyy sometimes
next badger
Python is no strong typed
urban gyro
python is great for what it does
normal burrow
situations where i'd feel c# or java would be candidate for the job don't exist where javascript or python wouldn't be more ideal because of their ability to stay lowly maintained really
next badger
hmm..."Unstable Discord Bot"
plush yew
I legit wrote a compiler, interpreter and REPL in python for selenium and appium. i created a programming language with two friends at work in python. being used in industry. python is amazing
is the new ue5 thingy just a improved lod system?
No
explain
Oh well maybe in a sense no one knows
urban gyro
to be fair ur trying to use a dynamic type language to write something concrete 😄
plush yew
google view-independent progressive meshing @plush yew
normal burrow
velcro they describe it as virtual geometry
which likely means the triangles are generated on the fly
next badger
@plush yew is windows 10 just improved windows 3.11 ?
normal burrow
pixel sized triangles alludes to a smarter preparation of them, than lod (imo)
gentle solstice
@next badger Yes
plush yew
@next badger sure it is
next badger
@gentle solstice then yes, UE5 just has an improved lod system
wild kestrel
I watch the interview and i think it simply huge update with huge features, potentially replacing some systems at most, i mean lot of stuff they showed was rised from UE4
urban gyro
no no, explain exactly how it works and how its done
gentle solstice
@next badger Except it's not an LOD system
wild kestrel
You want to say this demo
urban gyro
oh come on, i highly doubt that
normal burrow
console land is not pc land

BRUH '96
gentle solstice
Well, Epic claims the demo is only possible on PS5.
normal burrow
shared memory could make a lot of that tech not obtainable on pc. we have no idea what kind of specs are needed here
wild kestrel
This demo could indded be optimized for PS5
normal burrow
I bet @frank escarp would know a lot on the subject
next badger
there is no way you can make a demo on PC that can't run it
wild kestrel
@plush yew but what if oyu actully pu loading screens? :p
urban gyro
so RAM is just for shitsngigglze then
gentle solstice
@next badger What
next badger
WHAT IF? it was made on ps5???
plush yew
I am 1000% convinced, Nanite is progressive meshing.
normal burrow
you can certainly target platforms you can't develop on
dry moon
Most likely you'll get both Nanite and the original because of the limitations on few things. As well as size, that its kinda a developer decision what gets the nanite treatment based on the importance of the object. Or maybe this found a solution for the size who knows
brittle tundra
hey, do you think it's possible to have a "greenish" water shading (translucency...) ?
brittle tundra
😉
gentle solstice
Has never happened
urban gyro
i don't understand why storage speed is such a problem
half panther
look into post processing
wild kestrel
Fact that this demo may not run on PC or look worse does not mean UE5 wont run on current PC, there still lot of features they mentioned that can run on PC
liek that IK stuff
for exmaple
marsh swallow
that IK stuff looked awesome!
plush yew
@urban gyro People are fearing b/c they said billions of vertex it translates to read and write speed.
idk
gentle solstice
@urban gyro You can't see how streaming tons and tons of GB of data in real time requires a certain speed?
marsh swallow
built in IKs. 😄
urban gyro
i can see how u can cache a ton of that data in a bigass ram chip
gentle solstice
@plush yew Epic literally says the demo is only possible on PS5 due to its custom SSD
marsh swallow
i mean think about it though, we are getting faster and faster in SSD storage with NVMe
urban gyro
depends on motherboard
marsh swallow
its not about what can we do with it today but what we can do with it 2 years from now
plush yew
its custom SSD is only 565GBs
urban gyro
ddr4 with a fat bus will do the job, combine with ssd ur fine
gentle solstice
It's 40gb/s
urban gyro
dude there's people who run their entire OS from a RAM stick
next badger
it would be super awkward if ps5 will be released and there will be average pcie4 ssd
marsh swallow
okay so top speed is 5GB/s on the 40Gb Bus
marsh swallow
is PCIe 4.0 still 40Gb/s
next badger
@urban gyro you can't run OS form Ramdisk w/o loading the os there first (from hdd or ssd)
gentle solstice
But Sony has stated there'll be PS5 compatible SSDs available. Not sure that statement would make sense if the SSDs available are gonna be slower than what's in the PS5 by default. So they must either be releasing their custom SSD architecture, or expect other manufacturers to built better by the time PS5 has come out
dry moon
@plush yew In the blog, he talks about compression for disk space as well.
Geometry images were first designed for compression so disk space should be a pretty easy problem. One issue though is edge pixels. Between each page the edge pixels need to be exact otherwise there will be cracks. This can be handled by losslessly compressing just the edge and using normal lossy image compression for the interiors. As the patches mip down they will be using shared data from disk so this shouldn't be an issue. It should be stored uncompressed in memory thought or the crack problem will return.
urban gyro
marsh swallow
yeah i was just looking that up @urban gyro
urban gyro
@next badger yes u can
next badger
@urban gyro persistrent RAM? since when?
gentle solstice
That's basically what SSD is
urban gyro
ever since ups and uefi
wild kestrel
no SSD is not same as RAM
urban gyro
ram is much much much faster lol
plush yew

@dry moon That's quite interesting, i need to read that blog some more!
urban gyro
well, i suppose game development should be done on a workstation
marsh swallow
I use RAM as datastorage in some of my servers. 😂 its hella fast but dont do it without batteries.
urban gyro
just get a ups and ur g2g
wild kestrel
oh thats for cacheing
plush yew
I run my os on ephemeral.
I found PlayStation 5 SSD speeds hit 9GB/sec with custom 12-channel controller, if true thats pretty crazy for a console
wild kestrel
and it not half
blissful trail
Oof ue4 froze my pc
wild kestrel
RAM is not persistent
gentle solstice
@plush yew That'd be faster than the world's fastest SSD
plush yew
@gentle solstice Hence the pretty crazy for a console.
gentle solstice
@wild kestrel No shit, that's why it's copied to non-volatile memory
wild kestrel
thats cacheing
dry moon
Yeah and also the benefit in terms of shader, since vertex density will match pixel density, you can push all the pixel shader work to the vertex shader instead
gentle solstice
@plush yew But it's not just pretty crazy for a console. It's pretty crazy in general
urban gyro
regardless, u can use ram to dump all that extra data that the ssd can't feed
wild kestrel
but RAM part does not count to general SSD size
urban gyro
yes and thats why u cache that in ram
plush yew
@gentle solstice Oh, i thought the console part made it more impactful, you know why put that in a console wtf?
wild kestrel
not ot mention caceing is the thing since mechanical drives :p
blissful trail
Will ue5 be ps5/xbox only or will it be avalible for windows, ios/android, etc
urban gyro
how big is ur project? 100gb? then cache 80 gigz and boom
plush yew
"We're talking two orders of magnitude faster, meaning very roughly 100 times faster. Which means at 5GB/sec on the SSD that the game boots in a second. There are no load screens. The game just fades down and loads a half-dozen gigabytes, and fades up again. Same for a reload. You immediately get back into the game after you do. And fast-travel becomes so fast that in a blink of an eye you're present," Cerny said.

easier to just say ram and flash tho
plush yew
I'm curious, will there be 4.26? or 4.27?
maiden swift
@abstract relic And I’ll keep asking you to wait patiently.
next badger
ue5 was announced today, i think it's legit reason to discuss ps5 here
plush yew
Yes, and "its demoed on the ps5", so its relevant even though i doubt it
wild kestrel
@plush yew yes, as there some incompleted stuff in UE4, liek Chaos is half way implmented
urban gyro
@plush yew i think i heard final ue4 version to be 4.27 (or read it somewhere)
maiden swift
This channel is working as intended. Carry on.
weary basalt
Most people: “Next gen graphics look the same as now”. Unreal engine: “Hold my Triangles.”
Haha
Hold my triangles.
urban gyro
😄
dry moon
does anyone know if PS5 can do directx stuff?
weary basalt
Good comment on the UE5 video
urban gyro
technically, nothing will be able to hold the triangles cuz theres too many
wild kestrel
@dry moon no, DirectX is only software, Sony or else they changes soemthing in PS5 use there on grpahical library
plush yew
We are screen resolution capped girls and boys. Think about it, 4k res not being that common and we are limited by the number of triangles that can occupy a pixel so 4k screen res pixel count= tris is limit
wild kestrel
DX is owwned my microsoft ;p
plush yew
ssds get slower when they get full, ps5 will be no exception. if the size of the games start to be 200gb as standard, its going to be problematic for a lot of people
wild kestrel
and can be only used in there systems
wild kestrel
i have one :p
urban gyro
sure, but most ppl dont
weary basalt
Games will get sold at retail on physical 256GB NAND Flash drives
next badger
Luos has 2 4k screens afaik
urban gyro
for gaming it's the refresh rate that matters
weary basalt
Retail will be saved!
plush yew
I have a single 4k, a 2k, 1080 and 2 16x9 #simracinglife
maiden swift
They’re still in the minority, but 4K is more affordable than ever.
wild kestrel
yea 4k is cheap, cheper then actuall 4k TVs
plush yew
4k needs to be at least 32" or higher honestly, otherwise windows dpi scaling makes it pointless
urban gyro
i hate 4k for one reason. Anytime there's a minimap in a game, I have to move my head to look at it
next badger
@weary basalt hmm...i remember some games were sold on usb sticks in retail
plush yew
2k needs to be at least 27"
dry moon
also in terms of of triangles, you the blog talks about that too. Lot of info about the way it'll be stored in memory
With virtual textures every page is the same size. This simplifies many things. The way detail is controlled is similar to a quad tree. The same size pages just cover less of the surface and there are more of them. If we mirror this with geometry images every time we wish to use this patch of geometry it will be a fixed size grid of quads. This works perfectly with instancing if the actual position data is fetched from a texture like geometry images imply. The geometry you are instancing then is grid of quads with the vertex data being only texture coordinates from 0 to 1. The per instance data is passed in with a stream and the appropriate frequency divider. This passes data such as patch world space position, patch texture position and scale, edge tessellation amount, etc.
plush yew
1080p shouldn't be bigger than 24"

@blissful trail i dont htink there will be huge requirment jump from ue4 in terms of editor
plush yew
I wonder if they'll just create a fork on the ue4 repo and call it 5.0.0 😄
fierce tulip
was about to write but saw pfist write as well :p
urban gyro
just because a console has almost no bottlenecks dont mean u cant run on pc
ddr6 isn't reserved

@plush yew GDDR can be used with CPUs, in fact PS4 and X1 also use GDDR

it isnt now and it wont be in the future

@normal burrow UE5 was demoed on a PS5. This is relevant discussion.

@plush yew they did that because in those ocnsole GPU and CPU sheres memory, so for GPU sake CPU also uses it

the next gen consoles are most def near the rtx 2080

The PS5's GPU isn't even as powerful as my 1080 Ti
modern socket
but ps5 is the better console in my opinion from what i've seen
normal burrow
a game made for a very specific set of hardware elevates it

rly just use ram for that if ur that stuck for speed

We want the consoles to be the best they can be anyway
maiden swift
I’m still floored by “no baked normal maps or manually authored LODs”.

If i cant tell the difference of a pc game and a console, then id say thats good

with that many tri's it would look WORSE
normal burrow
keep in mind this could be a ps5 only feature pfist
modern socket
sadly ps5's gpu will probably be slower or equal to the 3060 lmao
wild kestrel
If you have poligons of size of pixels, using normal maps makes no sense, just use world space normals insted
urban gyro
ram can give u 20gb/s

so ram sizes or storage might not be a problem as thought
maiden swift
@fierce tulip Right? Lots of assumptions being re-evaluated.
plush yew
I highly doubt they would do something so platform specific, i mean yes pcs have on average something like a 1tb samsung ssd with only 540MB read and 520 write, but something has to be possible on a pc
it won't be any worse than current virtual texturing solution ssd wear&tear wise

lol no they are not 😄
plush yew
intel is at the same position as amd pre ryzen
normal burrow
a 3950x wouldn't be be bad either, but there are many niceties going threadripper with quad channel memory and all those pcie lanes
wild kestrel
Don't lisent to PC gamer hardware youtubers, with game dev more cores = better
plush yew
Lol they even said it themselves that intel was strides or steps behind amd
urban gyro
used to be roughly 60% faster
fleet cedar
I wonder how this new system will work with point cloud data, imagine taking out an iPad with lidar, scanning a real location and then poof there you go
urban gyro
eerm, im talking about the new tech
normal burrow
yeah though 3950x has 16 cores so its nothing to snuff nose at shadowriver
weary hull
o/
plush yew
its the instruction set, and intel compilers doing intel compiler things
normal burrow
but yeah something like luos's 3960x would be banging at shader compilation
plush yew
yep, instruction set matters,
intel compiler switches to a slow path if it detects an amd cpu
next badger
one think is with ue4, more ram = is better dev
plush yew
dont have that instruction? ouch gonna have to wrap it in about 300 other instructions to unroll that boy if its even possible
next badger
@plush yew wait, you can't host minecraft on own xbox?
normal burrow
don't think thats true plort. there are some intel hardware features used by adobe products that make them perform better than similarly comparable hardware from amd
urban gyro
intel and amd use almost identical instruction sets thho
plush yew
avx is a mess and even intel cpus doesn't support everything
amd is a generation behind on latest avx updates
plush yew
especially on server cpus there are many additional avx instructions
next badger
@heady moon error C2678: binary '*': no operator found which takes a left-hand operand of type 'const wchar_t [30]'
plush yew
some of them haven't yet hit end user intel cpus yet
heady moon
should I remove the * ?
bitter solar
Night guys and keep safe! dont get much time to get on here so keep safe and really looking forward to Unreal 5 engine next year 🙂 check out some of my work https://www.artstation.com/shauntwilliams
wild kestrel
I dont htink you guys tlaking about instructions set as indeed they are the same, but how CPU operates and they behave diffrently. Intel compile would compile the code in shuch order that it's optimal for Intel CPU
next badger
@heady moon i think i have the source of that project
plush yew
" Multiplying two 32-bit numbers takes two cycles on Hitachi's SH7604; 43 cycles on a Motorola 68030, and anywhere from one to 15 cycles on an ARM7. But how would a programmer know that? The statement a=b*c looks the same in any chip's C code. (ARM7 multipliers are data-dependant; the speed of the result depends on the magnitude of the operands. Try working that into your hard real-time system!)"
So its far more complicated than just instructions per second
heady moon
ok, but for now should I remove the *
even tho * is required as it returns an FString
normal burrow
happy hardware conversation alienation to everyone else here 😄
maiden swift
Cinco de Unreal.
normal burrow
@heady moon where is the * it is talking about?
wild kestrel
I remember i found some page in the past that had great documentation about low level optimization, descriptions how CPU and Compilers behave... but i forgot the name of it
heady moon
@normal burrow nvm unreal was behaving incorrectly
recompiled and it worked
even tho i compiled 3 times
in the 4th it worked
😂
abstract relic
Was there information on how the system is cooled?
wild kestrel
IT descibes how Intel and AMD CPUs behave differently to same code
abstract relic
Getting some vacuum cleaner flashbacks
sleek spear
im trying to change niagara particles color from a blueprint, can anyone help?
plush yew
Well considering instructions on different cpus from intel will behave differently its not really something we can change, all we can do is account for it in software
sleek spear
@next badger you like tha mac trash bin?
wild kestrel
@sleek spear yo uaksing how to change niagara attribute in blueprint, make attribute, tie it to specific property and set it in blueprint (there node for that)
normal burrow
when we start getting into intel v amd stuff thats surely where things go to #lounge i think?
abstract relic
That’s brilliant. Have enough airflow to keep it cool and provide a platform for flying vr
normal burrow
very cool cat.
abstract relic
Screw it. All hardware talk belongs to here
wild kestrel
@plush yew well yo can optimize the code if you detect specific CPU ;p if not fallback to original code
sleek spear
@wild kestrel i did that, and it doesnt seem to work for some reason
wild kestrel
What attribute name you trying to set in niagara?
next badger
@sleek spear yes, but not the macos...i think Corsair One is way better
wild kestrel
i mean via blueprint
sleek spear
@wild kestrel i tried changing Particles.Color and another one i made called Particles.Color2
sleek spear
ok thanks, i will try with that, and be back
@next badger yeah that looks nice
@wild kestrel but how can i use user attributes in niagara? i cant drag and drop them on an emitter and i cant choose them in bindings
maybe im doing something wrong in general, maybe i have missed something
wild kestrel
You need to use proper type of attribute for peoper property
so for color use color
or i dont remeber if it was vector
Looks like UE5 chat rush ended :p
plush yew
Just give ue5
sleek spear
@wild kestrel ok so i create a user attribute, of type linear color. done. then what do i do, how can i bind it with color?
wild kestrel
yes oyu need to bind attribute with property
snow crown
what is the best way to take good resolution screenshots of the editor?
highresshot only gets the active viewport
which is good, but I wanna get good high resolution screenshots of stuff like editor controls
sweet relic
PrintScr?
snow crown
that obviously works
dry moon
highresshot 3840x2160
snow crown
but, i was wondering if there was a highresshot equivalent for the editor
dry moon
and run it in new window
hollow ore
@wild kestrel when you playtest game jam games and it is network multiplayer, how do you play that? Do you use 2 machines or just play single player?
sleek spear
@wild kestrel but i dont know how to bind them
snow crown
@dry moon that does not get stuff like blueprint
hollow ore
Sorry random lol
snow crown
as I said, highresshot only grabs the viewport
wild kestrel
@hollow ore single, general behavior should be the same, then test it with friend to find issue related to high lentecy
hollow ore
Thanks! 👍
sleek spear
and yeah ue5 is awesome but its too far away to talk about it i think
wild kestrel
since localy on PC network runs with near 0ms lentecy and oyu wont see problems related to actual network lentecy
cerulean sandal
Where Can i Ask help about a performance problem?
wild kestrel
In fact LAN probably not gonna emulate what you can expect playing on internet
hollow ore
Makes sense yeah
sleek spear
@wild kestrel i can bind particles.attributes because i can drag them on the emitter and then use them, but i cant bind user.attributes
wild kestrel
can we screenshere?
sleek spear
sure
cerulean sandal
Where Can i Ask help about a performance problem?
normal burrow
here is fine probably
cerulean sandal
Alright so lemme explain a bit
Im trying to make a horror game based in a cave, the cave Is made up by lots and lots of rock meshes put together.... I currently have only the entrance part and the game gets 20 fps on my Ultrawide monitor with a GTX 1060 as a graphics card... The main issue Is probably the volumetrics and stuff... How can i improve performance drastically?
The GPU visualizer says that the main processing Is spent on post process and volumetrics
normal burrow
how much blueprints do you have?
normal burrow
a 1060 pushing ultrawide resolutions might be asking for a lot
cerulean sandal
yeah but 20 fps Is too low
I can play minecraft with Path Tracing Shaders and get 35fps
normal burrow
remove the voulmetrics and stuff and see what you could be getting
treat that as the max you can get
that might give you a better idea of expectations
normal burrow
at ultrawide?
normal burrow
so 60fps would be the most you could get with any volumetric stuff
normal burrow
yeah, i just mean: if there was no cost to volumetric stuff: that would be your best fps possible
cerulean sandal
Ok
normal burrow
and its at 35 now yeah?
cerulean sandal
No its 20
normal burrow
gsync display?
cerulean sandal
Nope
normal burrow
so your shooting for 30fps then?
cerulean sandal
Im getting 20 fps
Just 20
With everything applied
Volumetrics and Post Process are Just destroying my framerate
And i Need a way to make them less resource intensive
normal burrow
stencil buffers are for such things
normal burrow
if you can put a stencil bit in for where the post process needs to run, then it wont run over all the frame's pixels
but then your drawing more to get those stencil bits in as well
slim mica
Also you could reduce the render distance on the volumetrics
cerulean sandal
Its already on 6000
slim mica
4k and half the render quality
