This looks so impressive. No more lightmap or texture baking? Millions of polygons? Unbelievable stuff...unreal even oh ho ho!

"And that, in a nutshell, is the definition of a micro-polygon engine. The cost in terms of GPU resources is likely to be very high, but with next-gen, there's the horsepower to pull it off and the advantages are self-evident. Rendering one triangle per pixel essentially means that performance scales closely with resolution. "Interestingly, it does work very well with our dynamic resolution technique as well," adds Penwarden. "So, when GPU load gets high we can lower the screen resolution a bit and then we can adapt to that. In the demo we actually did use dynamic resolution, although it ends up rendering at about 1440p most of the time.""
"A number of different components are required to render this level of detail, right?" offers Sweeney. "One is the GPU performance and GPU architecture to draw an incredible amount of geometry that you're talking about - a very large number of teraflops being required for this. The other is the ability to load and stream it efficiently. One of the big efforts that's been done and is ongoing in Unreal Engine 5 now is optimising for next generation storage to make loading faster by multiples of current performance. Not just a little bit faster but a lot faster, so that you can bring in this geometry and display it, despite it not all fitting and memory, you know, taking advantage of next generation SSD architectures and everything else... Sony is pioneering here with the PlayStation 5 architecture. It's got a God-tier storage system which is pretty far ahead of PCs, bon a high-end PC with an SSD and especially with NVMe, you get awesome performance too."
But it's Sweeney's invocation of REYES that I'm particularly struck by. The UE5 tech demo doesn't show extreme detail at close range, it's also delivering huge draw distances and no visible evidence whatsoever of LOD pop-in. Everything is seamless, consistent. What's the secret? "I suppose the secret is that what Nanite aims to do is render effectively one triangle for pixel, so once you get down to that level of detail, the sort of ongoing changes in LOD are imperceptible," answers Nick Penwarden. "That's the idea of Render Everything Your Eye Sees," adds Tim Sweeney. "Render so much that if we rendered more you couldn't tell the difference, then as the amount of detail we're rendering changes, you shouldn't be able to perceive difference."
We do that all day for offline rendering.
That said, games with needlessly high poly models are going to need equally insane amounts of storage. Console SSDs will only be so large, and many people will be downloading these games instead of buying them on disc (not too keen on downloading 500+ GB's of data for a single game...)
The PS5 has specialized I/O hardware for the purpose of getting around typical NVMe bottlenecks, and the SSD in the PS5 itself is also somewhat customized. NVMe on PC has thus far been badly bottlenecked, to the point where the difference between a SATA and NVMe drive is imperceptible 99% of the time (not counting synthetic benchmarks). Sony is the only company so far that seems to have seriously wanted to tackle this issue.

What are next gen art pipelines going to be like?
Will skipping the optimization phases help reduce the infamous 'Crunch Time' at AAA studios?
If game studios truly start skipping the optimization parts of the art pipeline, what are the file sizes going to be like? Are the mid-late generation UE5 games going to be like 9 discs to install, and one disc to play? What about downloading games?
Will this have any impact on the film/VFX/Animation industry? The last few years I've seen Unreal Engine start popping up in behind the scenes content, like for "The Mandalorian". Are render farms going to one day be a thing of the past?
Will I even be able to run Unreal Engine 5 on my current gen PC?
Doubtful. Bad management will still be bad management.
Don't be scared guys, this purely benefits us and our artistic qualities as artists. The poly count isn't what is standing out here (that's just for marketing), but the fact that we can now remove the obsolete workflow of baking/retopo for enviro/hard surface assets. We will have to learn to texture assets now more like film/vfx artists, but it will be worth it. Realtime engine film making has been crossing over into gamedev for a while now and prominently moreso with shows like the Mandalorian using unreal engine as a backdrop.
Unfortunately, I don't see how this could benefit character artists since they will be constrained to make usable topology for animators still.
We should all be celebrating for the bright future we have. We get more creativity at our hands to be actual artists rather than wasting time cranking out technical art confining to budgets like machines.
From what ive seen about the DirectX 12 presentation you'll have to cut up your meshes in chunks pre-import for this. And yes stones are clearly the best case for such tech.
Also whats the file size going to be like? Making a full game in that fashion is then 20 TB? Where would I get that from?
Loading and rendering that is nice and all but it needs to come from somewhere. Im not importing 500 MB highpoly meshes by the masses in any scenario, thats just awful, but its great to have the option. The lighting is more impressive, especially as unity has none that works decently atm.
No intermediate language on Unreal 5 is really a huge misstep from Epic however.
Theres no way I get real programmers on C++ or Blueprints and in a case where they like it, Unreal for many people or teams will still be a no-go as a cause sadly. With unity being at a vulnerable point, this would have been a very strong move, but instead even more graphics instead of things the engine desperately needs, like viability to make non FPS/3PS games for non AAA teams who can afford dev teams crunching their lives away at C++ to make things work.
Got an ak-47 subd model, removed all of the very simple meshes like bolts and cylinders that would be very easy to make an optimazed version, and then decimated the rest of the model. It ended up with 460k tri, and the fbx is 44 MB. Comparing with an optimazed version of another lowpoly gun that i have, wich the fbx only weights 880 KB is quite a lot of difference.
Even if unreal would have no problem at all with mesh like this, exporting/importing and storing could be quite a pain.
Anyways still think and hope that we can say goodbye to baking normals on razor sharp edges like we do. Having a 3-5 edge bevel with weighted normals would make the mesh look much nicer and wouldn't be heavy too.
Only if something is technically possible doesnt mean its the right thing todo.
There is no need to create trillions of poly if noone will see it and its only a waste of resources.
As much as needed as little as possible.
It would be interesting to know if or how possible it would be to decimate the highpoly meshes. We would get absurdly high detail meshes for around x50 or x100 the file size of current meshes (or at least that is what I calculated over the top of my head).

I cannot imagine what kind of resources would be needed to create a full scale game with such a level of detail, If just one asset looks "average" you ruin the whole scene.
As much as I love this eye-candy, in a game I would prefer visual variety to visual awesomeness, if I had to choose.
This is a really cool tech demo, but good luck making a real game with it. There almost certainly a *ton* of severe drawbacks and restrictions to using this tech, which you simply haven't been told about because it is a marketing video. It would be quite naive to think this is going to significantly disrupt the status-quo of how art production for games is done in the next few years.
Should be enough for.. one or two games.. ahhhh com'on .. let it be tree!
Hehe , exactly my thoughts
Assuming that's the case(probably is) theyll be streaming in whichever mip of the displacement texture is required for the current view distance and generating the geometry from that so in terms of resource cost at runtime it should be pretty dynamic and flexible (and efficient) .
You'll still have to make good models with uvs and lods though I'm afraid, this stuff can only add information, not take it away
