[@anteshell]

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.

[@iconoclasttastic9258]

@@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. kzbin.info/www/bejne/n5OZkJZsqtGcgsk

[@Nickgowans]

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).

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.

Where some fella was talking about rendering dots instead of triangles to some classical music playing in the background. The implications were staggering to think about but now.... Like 14-15 years later, it's finally a reality and oh my gosh. Girls and boys, the future is looking bright. That much is certain.

[@WafflesIsTheStuff]

@etethstrseh yeye exactly. I just looked it up. Looking at it now I'm not sure what I'm listening to just like last time. The tech described is very promising and makes sense but the guy behind it just sounds like a college student hyping up their "not so special" homework assignment.

[@devskoll]

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.

[@iau]

So basically Nanite does what I thought game engines had been doing for years

[@prateekpanwar646]

Same, I didn't thought people would be manually making models for each LOD

[@zedsdeadbaby]

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.

How does Nanite performs when you get to the level of more than 1 triangle per pixel for everything from up close all the way to entire objects being so distant the whole object is just a pixel in size, filling up the whole screen?

[@LivelyGeekGames]

When I zoomed way out, it just used the largest cluster size, which may still have been more than one triangle, but it still performed quite well.

Next Gen games are about to become insane.

[@m4r_art]

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.

[@lordcarrot5355]

really high quality video

[@BB_O_99]

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.

[@LivelyGeekGames]

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.

[@BB_O_99]

@@LivelyGeekGames Yes, also how is done to avoiding mesh distortions, different than old decimation systems.

[@MarcV_IndieGameDev]

Would you not have bigger file sizes due to heavy model detail ? It will always be king to have optimised mesh? This looks like a handy way to apply a basic re-mesher to a 3d object and use as a background object.

[@LivelyGeekGames]

Yeah, you definitely have larger mesh assets from all the detail. The Nanite page covers this under "Data Size": docs.unrealengine.com/5.0/en-US/RenderingFeatures/Nanite/ But since you don't need to make custom LODs and if you end up not needing a high-detail normal map, the total size (mesh + maps) can be comparable.

[@outlander234]

@@LivelyGeekGames You didnt make as clear as you should have. Yeah the file sizes will not increase at all. Plus I heard them working on optimizing file sizes even more.

[@coleshores]

I believe that this tech was what John Carmack had in mind for IDTech 6.

[@SHIVAM.M.S]

Great video looking forward to see more 💯

[@LivelyGeekGames]

Thanks, I appreciate the feedback!

[@alb8573]

Interesting how the unwraping and texturing pipelines will changes.

[@RealDral]

But if you move back and forth then wouldnt you see a slightly different immage every time from the same perspective? Or does it the same pattern everytime on the object depending on the distance?

[@LivelyGeekGames]

It changes the geometry based on distance (watch with the cluster and triangle view), but even if the geometry is different due to the distance changing, Nanite does a great job of not making it noticeable.

I actually really like this channel dawg, I gave you that subscribe, unreal engine 5 is somethin anit it

Quixel brought the new megascan tree assets. Does it work with nanite?

[@Sebal007]

can you compare bot situations (nanite on/off) with instancing enabled? Your first run with nanite off was with instancing disabled, right?

[@LivelyGeekGames]

I tested this in a followup video here: kzbin.info/www/bejne/rGrOqqGLh7yKlas

@@LivelyGeekGames thank you for responding. I watched directly after writing this comment and forgot to edit it -.-' Thank you for the content and looking and user requests :)

[@v.syndication]

Layman-Question: Isn't that something similar to "instances" (dunno the right term anymore xD) in eg. C4D? One objekt, umpteen "copies", so you have fewer calculations?

[@LivelyGeekGames]

There are definitely some efficiencies using instanced meshes vs non-instanced meshes, but the rendering thread/GPU still needs to calculate which parts of that geometry to actually draw. I tested this a bit further in a follow-up video here: kzbin.info/www/bejne/rGrOqqGLh7yKlas

Hey, what's that song that plays near the end of the video? It's very nostalgic to me, and yet I never learned its name.

[@LivelyGeekGames]

It's actually just a stock acoustic song included with Final Cut Pro (which I edit my videos in).

[@TheMentalgen]

@@LivelyGeekGames I guess it's just royalty free music they got from somewhere. I have very fond memories of hearing this exact song in a chatroom flash game back in like 2009-2010
