00:00Oh

00:30Sleep, Izzy, the plowing plunker.

00:39Break me pearlies on this blasted pit-ridden tract.

00:53Where's Veergaard to Iroh?

00:56Aye, the devil's out of here!

00:58Don't!

00:59This rotten tract!

01:04Snack her!

01:11The brother killed us.

01:28No!

01:29No!

01:30No!

01:31No!

01:32No!

01:33No!

01:40No!

01:41No!

01:42No!

01:43No!

01:57No!

01:58Salt.

02:14Almost had me fooled, Fruin.

03:00Thank you, everyone.

03:01And welcome to the state of Unreal at Unreal Fest Orlando.

03:05We're here to show you what's next with Unreal Engine

03:08and so much more.

03:10We are thrilled that you're able to join us.

03:14But first things first, I'm here with Sebastian and Kaitek

03:18from CD Projekt Red.

03:20We have a lot to talk about.

03:22Hey, guys.

03:24SEBASTIAN KAYTECKI- Thank you, Wyatt.

03:28SEBASTIAN KAYTECKI- Thank you, Wyatt, and hello, everyone.

03:31With The Witcher 4, we're stepping things up.

03:33And to do that, we needed the right partner,

03:36one that truly understands that great open world games

03:39are all about art and technology coming together.

03:42SEBASTIAN KAYTECKI- Yeah.

03:43And look, our goals are completely aligned here.

03:46And around the launch of UE5, your awesome team at CD Projekt

03:49Red announced a collaboration to make open world development

03:53in Unreal even better.

03:55And it's an opportunity we just couldn't pass it up.

03:58So we've been working on a technical demo together

04:01to achieve just that.

04:02I think we should take a look at it.

04:04You guys ready?

04:05SEBASTIAN KAYTECKI- Born ready.

04:06Kaitek is going to play the build for us.

04:08SEBASTIAN KAYTECKI- Sure.

04:09Let's do it.

04:16SEBASTIAN KAYTECKI- This is a technological showcase set

04:18in the world of The Witcher 4.

04:21What you just saw and are going to see now is running

04:25on a standard PlayStation 5 at 60 FPS with ray tracing.

04:30So in the game, you'll be playing as Ciri, a professional monster

04:34slayer, a Witcher.

04:36She explores the world and hunts down monster for coin.

04:40The region we are in is called Kovir.

04:43And you'll get to explore it in the game.

04:46Right now, Ciri is investigating the monster.

04:48And after gathering new clues, she is heading back

04:51to a nearby village.

04:58All right, everyone.

04:59Meet Kelpie.

05:02Let weeds be weeds, Kelpie.

05:05SEBASTIAN KAYTECKI- So just like Geralthead Roach,

05:07Ciri has her own loyal companion.

05:12We return to town.

05:15SEBASTIAN KAYTECKI- These two characters

05:15needs to feel like one.

05:17Since you're going to explore the world on horseback,

05:19riding these two feel seamless, natural, and just fun.

05:23SEBASTIAN KAYTECKI- Yeah, and to support that,

05:24we're introducing multi-character motion

05:26matching in Unreal.

05:28So Ciri and Kelpie, they're perfectly synchronized

05:31when mounting from any angle and speed.

05:34SEBASTIAN KAYTECKI- And we also support root motion

05:36movement on Kelpie.

05:38So controlling her feels realistic and grounded.

05:42And there are also some really nice improvements

05:44to our Unreal Chaos Flesh Solver and these machine

05:48learned deformations.

05:49So you've got realistic muscles moving and stretching

05:51under Kelpie's skin without compromising

05:53the performance there.

05:54SEBASTIAN KAYTECKI- So let's leave Ciri behind

06:04for a second and talk about the world itself.

06:07So much of the Witcher world is natural, organic,

06:11especially Kovir with its dense forest and wild nature.

06:15SEBASTIAN KAYTECKI- Yeah, and wild nature is hard.

06:18SEBASTIAN KAYTECKI- And with Nanite Geometry,

06:19we've freed artists from so many of their old constraints.

06:22But we don't want to rest until everything we do in Unreal

06:25has that same spirit of freedom.

06:27There's always more work to do.

06:28And foliage is a huge piece of that puzzle.

06:31So we are excited to introduce Nanite Foliage.

06:37SEBASTIAN KAYTECKI- And in order

06:38to achieve gorgeous foliage density everywhere,

06:41while still being memory efficient, fast to render,

06:44we believe that a new idea was needed.

06:46So instead of the same card approach

06:49we've been using for the past 20 years,

06:51artists should be free to take a Nanite approach

06:53to foliage, modeling every single leaf and pine needle.

06:58And the old LOD tricks of the past,

07:00they needed a complete rethink.

07:02And in their place, it's a new adaptive voxel representation

07:06in Nanite.

07:07It's volumetric, it's fully 3D, it is super fast to render.

07:12And these dense clusters of triangles

07:13turn into these cubes, which at a distance,

07:16they're no larger than a pixel.

07:17And they react to the changing light of our dynamic sun

07:20and our shadows, and they allow artists

07:22to render whatever amount of foliage

07:24is needed to achieve their vision without compromise.

07:28SEBASTIAN KAYTECKI- And no compromise

07:29means how ambitious we are when it comes to bringing our vision

07:33to life with incredible visuals.

07:36But more than that, together with Epic,

07:38we created faster way throughout the world.

07:40We can now bring in more content more quickly for the smoothest

07:44possible experience as we fly down to catch up with Siri.

07:48SEBASTIAN KAYTECKI- Welcome to Valgrist.

08:03So Valgrist is a port town, a hub for fishing, freight, and mining.

08:08SEBASTIAN KAYTECKI- It's one of those places

08:10where you can meet shady characters

08:12or overhear gossip from other lands.

08:14It's also where Tui took on her current contract.

08:20High tech, let's leave Kelpie here and explore the marketplace and food.

08:26I'm so excited we can finally show you some of this stuff.

08:30Let's see what Valgrist has to offer.

08:31Ah, my father, not her again.

08:36SEBASTIAN KAYTECKI-

08:40SEBASTIAN KAYTECKI-

08:41SEBASTIAN KAYTECKI-

08:46SEBASTIAN KAYTECKI-

08:53Guys, notice how responsive the world is.

09:03Character actions directly affect what happens around you.

09:07Sometimes even setting off chain reactions.

09:10Everything is working together.

09:19Oh look at this poor gentleman being taught how to fly by an angry innkeeper.

09:25That's what happens when you cheat at Gwen.

09:30Okay, so this is the guy who gave the series quest his own.

09:45You probably suspect he has his own agenda in all of this.

09:51Get your ass up.

09:59A typical day's toil.

10:01Who in?

10:02Ah, witcheress.

10:04What news of my wagons?

10:06No eternity is taking that damn salt to arrive.

10:10I found them, and, well, suffice to say, they'll not reach you.

10:17As for the salt, I found not one speck.

10:22I presume this country is no surprise to you.

10:26No, no.

10:28Kabir's smuggling trade is of no concern to me.

10:31While Ciri decides what to do about that merchant, let's take a look at the character technology

10:52that powers this marketplace.

10:53Why don't we listen in on these fishmongers?

10:56They're selling their wares, chatting up customers.

11:13And there is tons of tech to play here.

11:16Even in this simple market stall.

11:18MetaHuman tools, improved Unreal smart objects, chaos cloth, and more.

11:23Yeah, and all of this exists to make sure that the gap in quality between Ciri and NPCs

11:29is as small as possible.

11:31Yeah, and closing that gap, it's not just about fidelity, right, but also authenticity.

11:36They should react to changes in the world around them.

11:40But the prisoner in Pillar isn't exciting enough for Wildress.

11:45Let's grab everyone's attention with the circus.

11:56But the great performance deserves a huge crowd though.

11:59Let's crank it up.

12:09So you are seeing tons of optimizations here to many of Unreal systems, including an entirely

12:16new Unreal animation framework, allowing us to fit easily in our 60 FPS budget, not just

12:22in rendering, but also with room to spare on the game thread.

12:27Over 300 animated skeletal mesh agents all going about their business.

12:32And the whole point is to leave breathing room for developers like you to introduce the

12:37gameplay and the systems that your players expect, empowering you to make your worlds

12:42come to life without Unreal standing in your way.

12:45You are right.

12:47That's the open-world RPG that we are making.

12:50But before we wrap up, how about one final check-in with Ciri?

12:59We are making this game to be the most immersive and ambitious open-world Witcher game ever.

13:06And we are making this a reality thanks to our work on Unreal with the team at Epic.

13:12I think what we are doing together is going to bring in a new generation of open-world RPGs.

13:17And I'm so proud of what we accomplished so far.

13:21We are too.

13:24So we're almost done, but before we go, here's a small gift for all Witcher fans.

13:32A first look at Lonexa.

13:39Onward, Kelby.

13:44Onward, Kelby.

13:48We've worked.
