@Milen (splicer) Parvanov Maybe you should first go and learn about Nanite technology used in UE5. It's not about instantiating. And even so, try to instantiate milion of polygons at the same time of the same model even using the same material being GPU instantiated. Conclusion: you have no idea what you are talking about.
This is such a HUGE step into having very realistic games without needing a NASA computer. I'm amazed by this technology and what developers like you can potentially build 🤩
Asterisk: as long as they involve simpler assets that can be replicated, so it can benefit from them all being instances of the same thing. I think that's my main take away from this. It's cool as hell *but* you're gonna see a lot of replicated objects (which might not even be a problem, just something worth being aware of)
Photo realism is more a function of light calculations and less about the models themselves. And in models, the textures are way more important than the 3d-model. No matter how good your 3d-models are, they will always suck as much as the lightning sucks. Just by using correct lightning techniques you can make even Minecraft look photorealistic. The strengths of Nanite is in performance and development work flow and the realism comes as a secondary side effect.

Nanite can render 20 mi triangles per screen if I remember correctly, so you can put trillions of polygons into one scene, that will not make a difference. The cluster system will reduce that to 20mi. The 4K image has about 8 to 9 millions pixels, so nanite can display 2x times triangles about the pixel count of the screen, so you will never going to see major difference compared to the scene rendered with the full polycount anyway.
@@michaellvoltare I did watch the video. And I've been using Unreal engine for 20 years since the late 90's. What you're failing to understand is that this example does not use a million high poly meshes. It uses one single high-poly mesh which it then copies (as what's called an instance) 999,999 times. Using only one object plus its instances is not an effective test of the nanite tech; because one instance repeated does not stress the i/o throughput of the CPU or graphics hardware. In short: one instance repeated does not use as much memory as multiple different objects would. In fact - instances are designed specifically to enable the same mesh to be viewed multiple times without a big hit to memory usage. If this had been a demo with thousands of distinctly different objects my comments would have been very different. If you don't believe me, watch DF talk about the Unreal engine 5 Matrix tech-demo that was just released showcasing Lumen and Nanite in a AAA game format. That demo runs at 24fps. They're pretty clear that they don't believe the current console gen (PS5, X series) will be able to push AAA titles at higher than 30fps. Some less-complex games (or games on high-end PC) may exceed 30fps with Nanite and Lumen running but it's unlikely that the current console gen will get there for AAA titles. ruclips.net/video/ib6_c6uliLg/видео.html
I remember the whole euclideon fiasco from many years ago, they did a similar thing with point clouds by basically only drawing data which was relevant and required to populate each on screen pixel with geometry down to sub mm precision, however the idea of using this in point clouds is ridiculous due to the unfathomably huge file sizes, impossibility of physics calculations and complete lack of shader support. However on their demonstrations, they managed to display impressively large (although ridiculously repetitive and simple) environments from high resolution point cloud data. This is a much more intelligent approach. Essentially it's just intelligent self building variable LOD
this combined with Nvidia's resolution upscaling will certainly prepare the future of AAA games at fantastic resolutions running on affordable hardware (a circumstance created by the low supply of chips and an influx of millions of new and young gamers). I hope to be one of the people working on stuff like this in the near future.

Nanite is awesome. Shame it doesn't work on mobiles or older hardware. I feel like nanite would really benefit older or slower devices so I'm curious to know why it only works on more modern hardware only.
Because it requires the use of compute shaders. Most mobile targets OpenGL ES2.0 still which doesn't support them. They literally built a compute shader software rasterizer to do this.
To my understanding part of it also has to do with the nanite system requiring crazy huge memory bandwidth with low latency as it streams and decompresses a crap-ton of nanite compressed mesh data from storage to memory constantly, only holding in memory that which is necessary for rendering what's visible on the screen.
Who ever conceptualized nanite, had the first white paper, and proof on concept, is a game changer. Thank you to that person. Then thank you to the dev team at epic for making it so easy to use.
they kinda did, but in a really crude way. depending on distance from the player/camera, models would instead display simpler hand-crafted versions of themselves to reduce workload on the hardware. but if it's not gradual enough you can notice the pop-in, from low detail to high detail and vice versa. nanite just does it on the fly without the need to manually produce lower detail models by hand & setting the transition distances. nanite is going to save a LOT of developer time, while looking a million times better and producing incredible performance gains. I will be shocked if other engine developers aren't furiously working on their own LOD solutions now.
@@TheObeyWeegee I thought it was really noticeable in half life alyx. Would be really cool if Nanite was open source for devs, even if it required a license/paid access. Now imagine Nanite and Dlss 3.5+ in vr in the future! That would be incredible!
I've only ever used Unity for game development, and I really like it. But seeing stuff like this makes my mouth water. Gonna have to give this a shot (as soon as I get a PC that can run UE5, lol)
Fantastic video! What a great demo, it's crazy how far this technology has come and the minds that made it possible. I wonder how this will optimize the mobile or VR experience. Or even how far Nanite can be optimized to see what FPS counts you can reach while achieving similar LOD. Gaming was due for some modern optimizations with intensive games are now.
All of this makes me wonder: Will other engines have the same feature or will everyone just start using UE5? Because even if UE5 isn't perfectly optimized for everything, just having nanite sounds like it should be an obvious choice.
Other companies will try to do something similar but it will take them a while and most companies don't have the budget for research and development that Epic does.
This engine is just such a mind boggling feat! Imagine the team showing this tech to their Epic execs for the first time and for the next two days, there are no questions because everyone is still completely speechless. Epic's own tech demo was already crazy but this video here shows how stupid fast this actually is. Essentially, this looks like the infinite detail demo we saw from this disappeared company a few years ago only this time, fully integrated with real time global illumination and physics. Absolute craziness. I wonder what this would look like with growing numbers of DIFFERENT models, not the same instance of the same thing. This could be done by creating the same ball under different files name and importing those.
Yeah and there are people saying nanite and lumen changes nothing and isn't revolutionary. This is basically a functional version of Unlimited Detail tech dudes but people can get their hands on and is less limited.
There's nothing particularly impressive about rendering instances of the same model as the data is already in memory but I understand how it looks. The truth is = if this were ten thousand different objects each with this geometric density - that would be impressive.
@@iconoclasttastic9258 It's impressive because almost no other graphics engine has done capitalized on this stuff. Also its doing more then copy pasting objects in memory, its doing DYNAMIC LOD... that is pretty awesome.
@@PRiMETECHAU Real time LOD has been around since the early 2000's. Again - this is impressive tech don't get me wrong, but when you understand the technology and code behind it, this isn't a particularly impressive demo.
@@iconoclasttastic9258 I don't think you understand the technology here. This requires only 1 high detail poly from the artist, not 3 or more to suit a LOD system that switches out models depending on distance.
Nanite is very impressive, and a super smart way to seamlessly optimise meshes for real-time. No doubt this will save a lot of inexperienced modellers from a world of lag
I've been getting into game development with Unity recently, but hot damn if Nanite doesn't make me jealous of Unreal 5. This is some seriously next-gen optimization technology.
This is amazing. Also amazing, the memory footprint size of indie games will bloom, because devs might think that unlimited polygons means to use all of them for everything. That might be fine, if Unreal didn't tend to make for very large game executables as it is. With great polygon handling, comes great responsibility.
Nanite kinda feels like the biggest revolution in graphics since PBR to me. My hope is that this technology will also make its way into offline rendering to an extent. I cannot even imagine how much faster movie frames would be rendered with this, since it's almost exclusively about quality and not render times there
Yes. It is impresive but only few people talks about it's limitations. Nanite can be used ONLY for static objects. No moving parts, No changing geometry etc.
@@kvmairforce Well it depends of the game type. In games like "FarCry" almost everyting is moving: grass, trees, animals, bushes, water ... everything is constantly moving. But I can agree that in games like TombRaider in caves most things is stationary.
Simple fact, nanite can render 20 mi triangles per screen if I remember correctly, so you can put trillions of polygons that will not make a difference. The cluster system will reduce that to 20mi. The 4K image has about 8 to 9 millions pixels, so nine can display 2x times triangles about the pixel count of the screen, so you never going to see major difference anyway.
Yeah, ideally it can cull down all possible geometry to have at most 1 triangle per pixel. It does an amazing job at quickly culling out unneeded clusters and triangles to render each frame. I even tested up to almost 1 trillion triangles in a world with another test, and it still performed quite well.
You know, when I worked at Epic in late 2003 to early 2005, working on UT2k4, James Golding once told me he predicted that, one day, rendering engines would probably be fast enough to use polygons (triangles) the size of pixels, and that map data might just be stored vertex info, per vertex. I of course didn't believe him, having been a 3d modeler and texture artist for years prior, but he was right on the first part of his prediction. Jesus...seeing this engine, it almost makes me want to get back into game dev.
damn i just saw you only having 20 subs. this channel is going places, great quality and good voice too. keep it up and people will come, ue5 is the big thing that everybody is looking for rn. Btw i found you through youtube search and filtered by "uploaded during last week". cheers!
@@LivelyGeekGames This video is indeed awesome :) Love these UE5 sneak peaks. I found it because youtube suggested it to me :D (btw, love your sense of humor)
The idea is very similar to adaptive subdivision surface that blender and other engines implemented a while ago, but seeing it into a game engine is really cool.
Although you are correct, I think we need to understand how hard taking the latency out must have been, as blender does not need to provide this feature at 60fps
@@snaileri That's an interesting limitation, that would mean you couldn't use this for trees and grass animated with the wind like in Valheim. Can you easily have a Nanite environment (dealing with stone, dirt, steel and glass) and then fill that environment with lower-detail "live environment"-props for greenery?
You can still use non-nanite meshes for characters, foliage, and other meshes that don't work with nanite, it doesn't need to be all or nothing. This is what they did in the UE5 demo project.
Ever since nanite was announced I’ve been flipping out about it. The capabilities this shows us are possible is insane. I’ve heard it may increase memory, which is a slight downside, but for real, even a trashy computer can work pretty well with nanites. I can’t wait to see how it develops further in the future 😁😁😁
Fear not, nanite uses a technology known as Mesh shaders or Task shaders as Nvidia calls them and were introduced with Directx 12 (this would be 2015 give or take) so it has existed for quite some time and I would imagine more than a few titles make use of them. Only reason there was no hype around it back then was because of the introduction of raytracing. But yes I agree this is really cool.
@@Gooseguy1000-1 It is revolutionary, mesh shaders take general purpose programming to rendering effectively making indexed triangle lists obsolete. I believe the microsoft has a talk were they go over the capabilities of this system titled 'reinventing the geometry pipeline'. As for the base it is compute shaders. Cheers
@@jonatanlind5408 I came across Mesh Shaders when sifting through the Vulkan API documentation. I read some of it and it seemed pretty powerful but I'm not ready to try using them.
I think it will probably have issues if you place a fully textured model with many texture maps. It will probably reach a limit, I'm talking a model with transpadency, caustics, displacement. It would be logical for it to have a lower FPS.
I'm not a developer and if I ever made a game it would be 2d but I watched this all the way through with full attention. This is despite the fact that today I'm actually really exhausted and have had a hard time paying attention to anything. You make good content.
Something that’s crazier is if you read the siggraph presentation this isn’t even hardware rendered. That’s right. What you are seeing is software rendered. Pretty crazy math here. It’s a different way of doing a rendering pipeline.
This isn't even version one, this is just a preview. There could be even more features once UE5 is officially released (which should hopefully be soon).
It's nice to see 60fps in UE5 at last. Shame the current gen consoles, or at least the PS5, probably won't see this in action unless some game dev legitimately believes people will be happy with 1080p30 as long as it's UE5.
When UE and unity combines to form Unreality, Nanite and lumen + DOTS will allow developers create incredibly realistic humanoid models for games without worrying about performance. A game character will be more realistic than yourself as a human being.
So essentially what you are telling me is 2 things. The assets I buy will work in my game, and the Tutorials I follow on youtube won't break my game because everything is run off the event tick? - fantastic! What I mean is... UE5 will be powerful enough to make up for my lack of skills. It always pisses me off when I get low FPS and I'm in a scene with 37 triangles and 4 actors and Unreal up here with their 6 billion triangle running smooth as shit.

Other companies will try to do something similar but it will take them a while and most companies don't have the budget for research and development that Epic does.
This is absolutely insane...
It truly is a great time to get into UE.
3:20 "infact my performance increased"
My coffee came out of my nose
This engine is just such a mind boggling feat! Imagine the team showing this tech to their Epic execs for the first time and for the next two days, there are no questions because everyone is still completely speechless. Epic's own tech demo was already crazy but this video here shows how stupid fast this actually is. Essentially, this looks like the infinite detail demo we saw from this disappeared company a few years ago only this time, fully integrated with real time global illumination and physics. Absolute craziness.
I wonder what this would look like with growing numbers of DIFFERENT models, not the same instance of the same thing. This could be done by creating the same ball under different files name and importing those.
I made another video using different meshes here: ruclips.net/video/v9kynURWW_I/видео.html
This will make games look insane. I couldn't believe it when I first tried it
Holy Crud man. This is impressive.
Yeah and there are people saying nanite and lumen changes nothing and isn't revolutionary. This is basically a functional version of Unlimited Detail tech dudes but people can get their hands on and is less limited.
There's nothing particularly impressive about rendering instances of the same model as the data is already in memory but I understand how it looks. The truth is = if this were ten thousand different objects each with this geometric density - that would be impressive.
@@iconoclasttastic9258 It's impressive because almost no other graphics engine has done capitalized on this stuff. Also its doing more then copy pasting objects in memory, its doing DYNAMIC LOD... that is pretty awesome.
@@PRiMETECHAU Real time LOD has been around since the early 2000's. Again - this is impressive tech don't get me wrong, but when you understand the technology and code behind it, this isn't a particularly impressive demo.
@@iconoclasttastic9258 I don't think you understand the technology here. This requires only 1 high detail poly from the artist, not 3 or more to suit a LOD system that switches out models depending on distance.
Wow!!! 50,000,000 triangles all in one frame. Unfortunately I can't see them all. My crappy 1080p monitor only has about 2 million pixels.
Haha, yeah. Definitely a bit of overdraw happening there.
The fact that there are One million objects in the scene itself is already amazing (without ECS).
This is super impressive, I'm excited to see what people do with this.
And... The UE guys just solved all the problems related on comments and showed It on Matrix Tech demo, amazing
unbelievable and yet so simple in it's idea
I remember Gran Turismo 6 did something like that on PS3
Honestly I’m amazed at the performance it was getting before Nanite. Afterwards, it’s just…. unreal
Nanite is very impressive, and a super smart way to seamlessly optimise meshes for real-time. No doubt this will save a lot of inexperienced modellers from a world of lag
Looking forward to your Xtreme Snowball Warfare game.
Nanite is truly next-gen in gaming. I can't wait to see it utilized by developers.
What a time to be alive!!
Hold on to your papers
Reminds me of how the 2014 LittleBigPlanet 3 did infinite levels with their “dynamic thermometer” that renders what’s close and hides what’s further.
This + fsr will make games run so well
I've been getting into game development with Unity recently, but hot damn if Nanite doesn't make me jealous of Unreal 5. This is some seriously next-gen optimization technology.
Ask them to start using mesh shaders for LODs, that's all what it takes
Stop being a pleb and learn UE. Unity is not even on the same league anymore if you want to do 3D
This is amazing. Also amazing, the memory footprint size of indie games will bloom, because devs might think that unlimited polygons means to use all of them for everything. That might be fine, if Unreal didn't tend to make for very large game executables as it is.
With great polygon handling, comes great responsibility.
people are gonna need to make free nanite DLCs so people can download them without having to buying a new harddrive and waiting 2 weeks to download
"1 million snowballs. It got better..."
I guess Epic just thought: "let's make it render faster with more tris. Why didn't we think of that before?"
Nanite kinda feels like the biggest revolution in graphics since PBR to me. My hope is that this technology will also make its way into offline rendering to an extent. I cannot even imagine how much faster movie frames would be rendered with this, since it's almost exclusively about quality and not render times there
Yes. It is impresive but only few people talks about it's limitations. Nanite can be used ONLY for static objects. No moving parts, No changing geometry etc.
Most things in game don't move, environment is a major part in games, but that leave more resources for things that do move.
@@kvmairforce Well it depends of the game type. In games like "FarCry" almost everyting is moving: grass, trees, animals, bushes, water ... everything is constantly moving. But I can agree that in games like TombRaider in caves most things is stationary.
Simple fact, nanite can render 20 mi triangles per screen if I remember correctly, so you can put trillions of polygons that will not make a difference. The cluster system will reduce that to 20mi. The 4K image has about 8 to 9 millions pixels, so nine can display 2x times triangles about the pixel count of the screen, so you never going to see major difference anyway.
Yeah, ideally it can cull down all possible geometry to have at most 1 triangle per pixel. It does an amazing job at quickly culling out unneeded clusters and triangles to render each frame. I even tested up to almost 1 trillion triangles in a world with another test, and it still performed quite well.
@@LivelyGeekGames Yes, also how is done to avoiding mesh distortions, different than old decimation systems.
really high quality video
Great example of how powerful Nanite is!
You know, when I worked at Epic in late 2003 to early 2005, working on UT2k4, James Golding once told me he predicted that, one day, rendering engines would probably be fast enough to use polygons (triangles) the size of pixels, and that map data might just be stored vertex info, per vertex. I of course didn't believe him, having been a 3d modeler and texture artist for years prior, but he was right on the first part of his prediction. Jesus...seeing this engine, it almost makes me want to get back into game dev.
Unity profusely sweating in the background
Well AAA isn't unity's priority so i doubt it
@@ciixo8510 le 🧂
damn i just saw you only having 20 subs. this channel is going places, great quality and good voice too. keep it up and people will come, ue5 is the big thing that everybody is looking for rn. Btw i found you through youtube search and filtered by "uploaded during last week". cheers!
Thanks, I appreciate the feedback! I'm hoping folks find the videos useful, but either way I'm having fun making them while learning Unreal.
@@LivelyGeekGames This video is indeed awesome :) Love these UE5 sneak peaks. I found it because youtube suggested it to me :D (btw, love your sense of humor)
That’s amazing man! Thank you for this👍🏽👍🏽👍🏽
Incredible overview and test of an incredible new tech. Thank you for this.
Nanite is incredible. I love that I'm alive to witness this leap in video game tech.
The idea is very similar to adaptive subdivision surface that blender and other engines implemented a while ago, but seeing it into a game engine is really cool.
Although you are correct, I think we need to understand how hard taking the latency out must have been, as blender does not need to provide this feature at 60fps
@@gwentarinokripperinolkjdsf683 yeah nanite does this but far better
Thanks for teaching me how nanite works
nanite reminds me of Euclideon's unlimited detail tech demo from 2011
This looks absolutely revolutionary.
Is it really true that tri limits are gone for good?
Definitely not. You can't build moving stretching meshes (i.e. character animations) with Nanite. Only static environments.
@@snaileri That's an interesting limitation, that would mean you couldn't use this for trees and grass animated with the wind like in Valheim.
Can you easily have a Nanite environment (dealing with stone, dirt, steel and glass) and then fill that environment with lower-detail "live environment"-props for greenery?
You can still use non-nanite meshes for characters, foliage, and other meshes that don't work with nanite, it doesn't need to be all or nothing. This is what they did in the UE5 demo project.
@@LivelyGeekGames couldnt you just throw a vertex shader on the triangles after nanite processed them(if it allows it) to make animated grass/trees?
@@id_NaN I don't think Nanite supports vertex shading yet, but I have not tried it.
The 1 million player battles will be epic!
Hah, now we just need game servers that could handle that many!
thats pure magic for me... to the genious guy who came up with that: thank you bro! I just wish that we could use that with raytracing...
More videos like this please! So sayeth the panda.
That's hella dope. Finally we can get next-gen graphics despite the hardware companies slacking for the past decade.
I dont know what rock you’ve been living under, but the advances in discrete computer parts have been astounding. Especially in the pc space
I'm a Unity guys, I have no experience with Unreal... Now I want to. God, it seems unbelievable, really.
Can you imagine big companies with machinery they have to build games with this ? it's going to be insane..
Ever since nanite was announced I’ve been flipping out about it. The capabilities this shows us are possible is insane. I’ve heard it may increase memory, which is a slight downside, but for real, even a trashy computer can work pretty well with nanites. I can’t wait to see how it develops further in the future 😁😁😁
Fear not, nanite uses a technology known as Mesh shaders or Task shaders as Nvidia calls them and were introduced with Directx 12 (this would be 2015 give or take) so it has existed for quite some time and I would imagine more than a few titles make use of them. Only reason there was no hype around it back then was because of the introduction of raytracing. But yes I agree this is really cool.
I imagine they must have had a base for what to go off of, but this is a revolutionary improvement in my eyes 😁
@@Gooseguy1000-1 It is revolutionary, mesh shaders take general purpose programming to rendering effectively making indexed triangle lists obsolete. I believe the microsoft has a talk were they go over the capabilities of this system titled 'reinventing the geometry pipeline'. As for the base it is compute shaders. Cheers
@@jonatanlind5408 I came across Mesh Shaders when sifting through the Vulkan API documentation. I read some of it and it seemed pretty powerful but I'm not ready to try using them.
Can't wait too. This will really go well with my next project.
My mind has been boggled
I think it will probably have issues if you place a fully textured model with many texture maps. It will probably reach a limit, I'm talking a model with transpadency, caustics, displacement. It would be logical for it to have a lower FPS.
Nice I can now use my beginner projects as an artist in games 😂
Very good, Thank you!!!
I can't wait till Epic cracks how to get Nanite functioning on all meshes including skeletal mesh actors.
I believe that this tech was what John Carmack had in mind for IDTech 6.
I'm not a developer and if I ever made a game it would be 2d but I watched this all the way through with full attention. This is despite the fact that today I'm actually really exhausted and have had a hard time paying attention to anything. You make good content.
Thank you!
Very cool, Thank you
Something that’s crazier is if you read the siggraph presentation this isn’t even hardware rendered. That’s right. What you are seeing is software rendered. Pretty crazy math here. It’s a different way of doing a rendering pipeline.
This is just amazing!
This will actually be a quantum leap Forward in battle sim games like total war.
Nanite 2 is going to be amazing if this is the first iteration of it
This isn't even version one, this is just a preview. There could be even more features once UE5 is officially released (which should hopefully be soon).
Next Gen games are about to become insane.
THIS IS AWESOME MAN!😍😍❤❤❤❤
So, an automated lod mesh generation? Very nice!
A new LOD Tech now the engine can render almost everything from afar 😙
Future of gaming will be first person snow ball shooters, with millions of snow balls being fired at once.
Haha, I guess it would make sense to now make a snowball fighting game...
This video is beautiful @LivelyGeekGames. Absolutely beautiful. Keep Doing more videos please. 10/10
"It just works."
Except that it really does.
It's nice to see 60fps in UE5 at last. Shame the current gen consoles, or at least the PS5, probably won't see this in action unless some game dev legitimately believes people will be happy with 1080p30 as long as it's UE5.
When UE and unity combines to form Unreality, Nanite and lumen + DOTS will allow developers create incredibly realistic humanoid models for games without worrying about performance. A game character will be more realistic than yourself as a human being.
Interesting how the unwraping and texturing pipelines will changes.
Finally, I no longer need to collect my golf balls from the game
Best explanation so far.
So essentially what you are telling me is 2 things. The assets I buy will work in my game, and the Tutorials I follow on youtube won't break my game because everything is run off the event tick? - fantastic! What I mean is... UE5 will be powerful enough to make up for my lack of skills.
It always pisses me off when I get low FPS and I'm in a scene with 37 triangles and 4 actors and Unreal up here with their 6 billion triangle running smooth as shit.
Will be a game changer
Literally
It's A Game Changer
Excellent quality, informative, and straight to the point, i was suprised when i saw you only have 201 subs, i hope your channel succeeds and in the mean time, i'll be the 202nd subscriber hahaha
Thanks for the kind words! And for the sub!
i need nanite in every game now
