where, I can't find it

@@remphey 4:00

You can also see it in the beginning when the static mesh is opened. In the sidebar there is also a Nanite option to enable above LOD settings

@@IPpainting yeah at 1:36

Same happened with me

I just got hard baited :D

We still can

to be fair, in terms of VRAM this represents a single object only, if every one of those objects was a different one it would require VRAM for each one of them, eventually you'd run of out memory and the performance would decrease not because of the rendering but because of the VRAM/RAM. If this technology becomes popular you can expect that (V)RAM and disk space becomes increasingly more important for gaming

This looks amazing!

@@kebrus Disk space not a problem for Nanite. Copy pasting my other comment Asset size is not a problem with Nanite. A 1.5 million poly asset takes only 20mb on disk in Nanite format. This is because Nanite does not need to have normal maps or multiple LoD's stored in disk. And Nanite comes with its own proprietary compression algorithm. VRAM is a problem a bit, I did run out of VRAM when experimenting with UE5 on GTX 1080 which caused TERRIBLE stutters.

@@Navhkrin the amount of space the asset occupies in your disk is not the same as the final build. A 20 mb texture for example compresses really well into just a few kb depending on the compression used, GPU also support some texture compressed formats. The same can't be said for meshes. While they can also be compressed devs usually refrain from it because it produces too many visual artifacts so they don't compress that well. Just because you save a single normal map, which btw already compresses really well, does not mean it directly compensates for the increase of mesh data. And we aren't counting with extra data that may be needed like vertex colors, normals, tangents etc. I'm certain epic did a great job at their special compression algorithm, but there are no miracles

They Played The Reverse Card lol, This Is TRULY Ground Breaking

Imagine If They Do Something Similar On Mobile, BRU!

Yea it's really impressive. Especially useful for real-time movie production. For games it can become an issue with file size, but with clever re-use of assets etc it's might not be that taxing on file size anyway since you won't need 5 versions of the same mesh for LOD's. Time will show :D

@@johnhauge2178 you could maybe save a decent bit of space by relying on displacement maps instead of storing the whole high res geometry.

@@NickTheSickDick yea, can't see the use for having sculpts with millions of tris necessary at any point. So having a optimized mesh is still necessary, Would need a certain amount of polys to make the displacement map work too though.

you need RTX for this I think

@@akzork you don't. not even lumen requires RTX. research before talking shit

@@resonance-cascade wow chill I was just saying. You must be having a bad day.

The scene is not small tho.

I mean it's easier to get 1TB SSD than new gen CPU or GPU.And cheaper.

The scene is pretty big but the assets are reused a lot. Someone posted a packaged version of that and it was only about 22gb.

the map is ginormous, only the play area is relative small

@@matth3601 do you know where the packaged version is uploaded? I'd like to check it out...

Looks like a lot to learn on the new engine ^^

We need more VR games made from Unreal 5!! Boneworks, Lone Echo and Half-Life Alyx spoiled me. 😁😁

@@henryjohnson-ville3834 yeah they are currently developing the vr version of ue5 so hopefully it will be great

@@ironmr_mental4023 To be more specific, they are working on VR support for Nanite, they aren't developing "VR version of UE5"

@@Navhkrin That is so freaking awesome to hear!! The only thing now is for a talented development team to make a game. I have so much ideas for this one VR Super Human game I wanna make but need 10+ million to develop. 😅 K!lling them terrorists, drug dealers, human-trafficking rings and corrupt politicians/police all with a storyline.

The '640K' quote won't go away

Yeah, mesh shaders are going to change everything, but mostly game install sizes

Asset size is not a problem with Nanite. A 1.5 million poly asset takes only 20mb on disk in Nanite format. This is because Nanite does not need to have normal maps or multiple LoD's stored in disk. And Nanite comes with its own proprietary compression algorithm.

@@Navhkrin A simple counterexample: The Bust of Nefertiti, the official scan, compressed, is 223MB for a 48cm tall limestone and stucco statuette. Of that the bare uncompressed geometry is 850MB. In spite of what you think, Nanite needs to generate a series of LoD meshes from this, and those can't be generated on the fly (note the pause when you load/enable a new Nanite asset). So those are stored as well. So you tell me, how much smaller can you get nefertiti, as a complete mip chain, and then we can talk apples to apples about game install sizes after Nanite.

@@falkreon I mean thats the whole point is it doesn't have to create LODS. its downscailing on the fly so its just one single LOD0 quality mesh. so yeah it will optimize the Nefertiti bust. same shit as a 2 million poly bust from zbrush

Yes your mind is blown up 😂

Both literally and figuratively a game changer

It's not a game changer.... It's a game maker 😁

I see what you did there

Literally

that's what i thought too

Yes RIP disk space, I was experimenting earlier, the disk space is insane

Not really. Mesh files are typically much smaller then high res Texture files, Plus if a scene has hundreds of the same model it isn't saving hundreds of the same mesh file on the Drive, It is calling from one mesh file and duplicating it across the scene. 50 Million polygons for a single character model like the golem thing in the latest Unreal demo is complete overkill. Final Fantasy 7 Remake characters already look great with just 50 Thousand polys.

@@ShawnPhillips2007 then why that empty game is hundred gig ?

@@ShawnPhillips2007 True. The texture file sizes are insane and we don't need 50 million per character or asset I know they will optimize this. It is just concerning with games like COD not even utilizing this technology and are at 150gb+.

You seem to have missed the second part of the video. It was almost 2 billion. He started with 128M before he turned on Nanite and then duplicated that 15 times.

@@cagefury3789 yeah i wrote the thing when i was halfway in the video but i was too lazy to modify the comment hehe

Well it was just over 5M after enabling nanite so of course you get high performance

@@redsky5440 Well yes, of course it's only rendering 5M at that LOD, but the impressive part is that it's still keeping track of those billions of polygons and choosing when/how to add/remove/combine them for the final image at any given distance with no visible artifacts and relatively low overhead.

@@cagefury3789 not only that but it automatically generates those LODs, 3D artists dont have to model LODs anymore, its all fucking automatic now, only needing the highest quality assets... Its fucking amazing.

same

Newer consoles are able to compress game file sizes massively in comparsion to last gen not mention how much game devs are able to compress file sizes. for example Killzone: Shadowfall was originally going to be 200-400gb but was compressed down to 40gb

@SpyShadow28 1 gbps? holy shit I didn't even know that's a thing. I thought the most you can get is like, 100-200 mbps

It will be the return of physical copies lol. you just order a drive that has the game on it

I don't really think that storage is going to be a problem by the time the games really hit the market though... This next gen of micro SD cards are at the tb rates already, for SSDs starting to get a serious growth is not off sight.

There is no memory bottleneck. Nanite meshes are using proprietary encoding, they are actually much lighter than you think.

Those dislikes are from Unity developers

1080p, rtx 3080, 64gb ram, 16core cpu. Did not checkany Load

At high resolution it be giving less optimizations and might not give any boost of performance at all, 8k at least. But if use DLSS 4k to 8k it might be nice, especially with temporal supersampling (not very exited it still blurs like good old TAA and temporal upsampling).

​@@eclairesrhapsodos5496 I just tested the UE5 Demo Content myself but i only have a 1070 and the description sais, 1080 is minimum requirement. So i am glad it worked at all. But wow, i still was surprised.I mean, it didn't run well. Of course it does not run perfectly with 1070 and i have to be honest, the new engine realy requires alot horsepower if you want to benefit from it as much as possible. But i don't see a huge problem with it. I mean if starting developing with ue5 now, and developing a game which will be available in 3-5 years i see no problem. Yet, how do the ps5 or the new xbox gonna benefit from it? I don't think they will be powerful enough. I cannot imagine many games coming out with all features turned on. Maybe in a few years.

Do you have old CPU? There is a bug that affects older CPU, like 4xxx Intels, causing shader complication times to be much longer than they should be.

@@kazioo2 Nope, i7 10th gen. With 64GB ram and samsung 970 pro ssd. Pretty fresh system.

Hopefully in the future we can have hard drives with petabyte storage and terabyte storage with be the new gigabyte and so on so it will all work out, it’s just a matter of time

@@itselliexoxx Don't get me wrong, I can't wait to see what people can do in film/game industry with this. But I really hope technology follows for a average Joe and is affordable..

Yes

Way more than that: instanced rendering is easy mode. Your CPU is happy only doing one call, but the GPU will choke trying to transform, clip, etc. 100s of millions of vertices / polygons. Nanite is dynamically computing the optimal mesh triangulation every frame such that you have about one triangle per pixel. This means you only ever have about 2 million triangle to render at 1080p, no matter what's on screen. This means assets can be created at hilariously higher detail and used far more without causing performance issues, as the video shows.

Yes, its not like cad fps result would be same if you had 1000 different assets

@@MarvelMaster Except that instancing does (sometimes massively) improve performance if you're CPU bound.

Better overall because it creates different LOD models dynamically at much tighter increments.

the increments are pixel-based, thats why its so efficient and smooth and the same time.

Not deleting, scaling then to be 1:1 with the pixels then just not sending the rest to the gpu

@@pezz0tti lol rip hard drives then. that sucker will die fast from so many writes and read :D Amazing tech..so its literally always streaming data of the nanite stuff while you move the camera around... crazy

There is a video with physics enabled on each mesh

or *colliding* with them

@@nou4898 From what I understood, it's only about meshes visually. And for collision visual meshes not being used to detect, but rather separate collision hulls.

not so. nanite uses it own proprietary mesh and compression format. nanite meshes are actually significantly smaller on disk than the same model without nanite. docs.unrealengine.com/5.0/en-US/RenderingFeatures/Nanite/

@@TheButtDr I know. However that is the packaged version AFTER compression. Unless Zbrush, Autodesk and other companies with similar software will implement nanite as a form of export option we will still be stuck with the huge innial files during development.

Well they said you can attach static meshes to skeletel meshes like they did with the ue5 boss if I got that right

Hey man it wont be that bad. You can take a look at old Nintendo games and how developers have saved space in these game cartridges. I bet we can figure something out

yes sure, but then they won't look as good. At least with the technology we use right now, when we store the assets as meshes, you mathematically can't compress up to a certain point without loss and after compression you often also have problems restoring the information fast enough to read it in real time from disk to load it into a game. To have those amazing visuals, either cloud gaming needs to be working better or we need a completely new technology to render things. Maybe neural radiance fields are a step in that direction, but time will tell :) For now I'll stay with average looking games that fit on my disk :D

@@albinoameise back in the day they used a full cartridge for one single game... nowadays we're gonna be using a full drive for a game lmao.

@@albinoameise well you don't have to compress everything to hell haha. We will find a trick or two like the 8 bit console developers did. The glass half full :D

Visual error of Nanite is 1 pixel per triangle max. Tweakable by developers, in practice, I experimented heavily with UE5 and could not notice any visual difference noticeable to human eye.

Just a guess but dont you have to convert meshes on import to be compatible with nanite?

I think that Nanite is good for photogrammetry and pre made assets cuz you dont have to manually optimize it, but if you're making an environment or prop in a DCC tool it would need the same asset workflow, sculpt then, decimate, retopo, uv etc, you cant unwrap or texture a million+ polygons mesh(ZBrush doesnt even exports high res meshes), the great thing is that you dont have to worry about LODs etc, but the current asset workflow is still needed, things such as foliage or any dynamic object it wont work.

DX12 just use LOD better with "mesh shading" and its gonna crash if you put so much detail. It is instanced placement but technology is way much better, I especially love huge map loading in realtime, without loading level - like it just drawing only needed clusters/collections nearby. Loading screens is no more lol maybe.....

@@eclairesrhapsodos5496 wasn't there some NVDIA's Mesh shader that did this?

@@utkarshjha9547 Mesh shading its Nvidia mesh shader

It is no mesh instancing so it doesnt matter... I have not enough ssd space to download 1000 quixel assets and test^^
