New Tools for Building Photoreal Worlds in Unreal Engine 5.2 | GDC 2023

Watch the recording of Epic Games’ tech talk from GDC 2023, ‘New Tools for Building Photoreal Worlds in Unreal Engine 5.2’.
In this talk, we take a deep dive into some of the powerful new features and updates in Unreal Engine 5.2.
Learn about new tools that empower artists to quickly and efficiently create large worlds; a paradigm-shifting material authoring system that enables users to focus on how a material is composed, assembled, and layered from slabs of matter to achieve visuals not possible before in real time; and the latest additions to Chaos physics for vehicle and fluid simulation-all showcased in a demo you won’t want to miss.

I can’t emphasise enough how eager I am to see UE5’s physics engine progress further. Currently it seems a little bit ham-stringed compared to what’s currently possible in the world of real-time physics, and from what I’ve seen a lot of the developers I follow who’re working with the Chaos system are unsure how/if it’s all going to stabilise and cohere. The ideal situation would be to have a physics system where all the different elements (rigid bodies, soft bodies, cloth, cables, rag-doll / skeletal meshes, fluids, fractured meshes etc.) can all coexist and interact with one another, and for that to be performant on a level that makes it viable to base real time game mechanics around them. Obviously that’s harder than it sounds, and it sounds hard, but I see it as an essential component of the engine. All the pretty graphics in the world can’t help a game if everything in its environment is inert and uninteractive. Perhaps someday we’ll have a ‘Nanite moment’ where they figure out a way to increase the amount of physical bodies that can be simulated in a game world by orders of magnitude and I can finally achieve my lifelong dream of bathing in an Olympic swimming pool full of jelly armadillos…

Is there the possibility to download the PCG demo to study it?

[@mv4458]

This! We need to see those graphs!

[@perfectionist724]

Dang. The people at epic are awesome and smart!

[@NestGFX_]

Loved this event ! This new PCG framework looks promising. I'm hoping that it would replace the old procedural foliage system, because that takes a lot time to get a decent result. Also is there any demo available to play around with new PCG system ?

[@andrinSky]

Can we Download this Fantastic Scene/Content?

[@BenMcNelly]

Great talk @ everyone in the video

[@matthews7895]

Loved this talk :)

[@marshal487]

Thank You😍

[@bishokukai2445]

I love it. Amasing.

[@rafaelglobalsupport]

Thank you very much, I'm still learning, I'm from Autodesk.

[@KHos73]

Where can we get all this from, I want to check it out

[@AlexGranddd]

Yay 3d environments!

[@quackcharge]

anyone have an idea what kind of node HexSampleNRM is?

[@alxleiva]

Fantastic! Definitely dissociating themselves from Houdini is the right direction

[@JordanHalsey-Artist]

That is not what is happening. To me it seems more about coherence that already exists in Houdini.

[@dimoronen]

What's the problem with Houdini? I do agree it is good that they have their own in-engine solution but realistically it will take a really long time to have all the functionality that Houdini offers.

[@alxleiva]

@Kuro1n well how much is Houdini? And even if it would be free it's a third party they can't control. Fragmented pipeline too. Now you can model and animated completely in engine. If these tools are gonna be so important to developers they can't rely on an external company

[@alxleiva]

@@JordanHalsey-Artist they have a long term vision where developers can have everything they need in engine. You can see how they already stated filling the gaps with modelling tools and control rig so you don't need Maya any more. Houdini is next.

[@dimoronen]

@@alxleiva Price definitely is a problem, can't deny that! It is good they are working on something like this but to reach industry standard for each and every aspect of game development is very very difficult and will take a long time. I'm not even sure it is wise to integrate it all into one monolithic program.

[@PP-qi4fp]

Can it generate at realtime in packaged game?

[@SuperMyckie]

Are all these available in the 5.2 Preview.. or will only be available in the full release of 5.2?... especially the MH capture.... i really dont want to spend the long time and data to upgrade only for all of them not to be available yet in 5.2 Preview

[@The9PointStar]

I saw some videos from random people using the new the procedural foliage so i imagine it does..

[@SuperMyckie]

@@The9PointStar oh ok.. thanks

[@giacomomartinelli5185]

I'm pretty new to Unreal engine but I have a HUGE problem. After shaping the landscape, saved the project and closed the program and restarted and re-opened it, the world window is no more. I don't know how but it doesn't appear. How can I open it again?

[@Carlos96AM]

Open the window tab, upper left part of the viewport, and click on world window

[@perfectionist724]

I hope epic works alot more on cloth physics. I really want to see clothes that react to the players entire skeleton! You guys do this.. you will be my heroes! Lol

[@makkon06]

my attention breaks down every time someone mentions the Metaverse. I just can't take it seriously. great talk otherwise

[@masterodst1]

You're seeing all of this and you deny that its clearly happening. All of the tech is being built before our eyes especially with things like omniverse creating a standardized and interoperable render system?

[@makkon06]

@@masterodst1 I'm literally in this industry, you're posting cringe

[@RADkate]

@@masterodst1 standardized and interoperable render system wont happen, ever, first problem adobe, second you cant feasibly expect everyone to use the same naming convention etc. even today we both have roughness and smoothness more or less the same thing but different because for the sake of it

[@zorropotatz]

interesting

[@LordLuigi_Rigs]

First!

[@zhenzhang3451]

without physical simulation there is no point to create things like this.... we need real time super power physical engine

[@DrangusKahn]

That's what Maya and Houdini are for.

[@number9letterk]

In UE: Niagara!! I learned recently that Niagara is very capable in terms of simulation (and Epic even refers to it as useful for simulations in some of their Niagara talks). I thought for the longest time it was just for particles and VFX but it's not. 🤯

[@kmturley1]

"Photo realistic" not Photo real

[@harriehausenman8623]

sis last tolk waz an insült! 😠 AI would've been better 😉

itoosoft time to be scared of the competition time to move out from autodesk YES

[@kraney195]

Please take the word "Metaverse" off of your dictionary, it puts me off and made my head blank for a moment

[@MilieuChris]

Welcome to the fun of getting older. Nearly every good idea gets captured by the zeitgeist and subsequently blended, stretched, blown out of proportion, and eventually turned into meaningless soup. Curious, what term would you use today for virtual worlds we can share and interact within? Something that is not enclosed within a specific game universe or set of corporate owned intellectual property?
