Unreal Engine 5

Unreal Engine 5 walkthrough.^[1]

Lumen has done a great job in really bringing to to life this area. As you can see, there's light bouncing off of the surfaces and casting into the rest of the cave... I love how you can also see the detail in the costume and the cloth that we have now.^[1] – Steven Sharif

Unreal Engine 5 is the graphical engine for Ashes of Creation.^[1]^[2] The game was originally developed in Unreal Engine 4.^[3] Migrating to UE5 required some front-end work, but in the long run it will be easier to do so in the alpha phases of the game, rather than closer to release, or post-release.^[4]^[5]

Unreal Engine 5 enables improved forms of locomotion/animation (motion warping), such as crouching, tilting and mantling.^[6]^[7]

What it provides in my opinion as person who enjoys PvP is it adds additional dynamics to what is possible from your opponent or from yourself. You know, if there is a ledge and jumping off that ledge is going to deal a lot of damage to me when I hit the ground and that puts me at a significant disadvantage, maybe I have an option to jump off the ledge at a point where I can mantle onto the side of a cliff or something. Now the give and take there is I won't be able to use my skills while I'm mantled. I won't be able to react easily, but I didn't have to take the fall damage per-se. Or if there's an obstruction and you know I'm going to take a significant reduction in speed so that I can crouch and make it past that, and now I have a effective line of sight has been obstructed as a result of that decision. I think it adds interesting elements to the battlefield and the key here is going to be making sure that it's not cumbersome- that it doesn't feel opposite of the flow of combat.^[6] – Steven Sharif

Unreal Engine 5 Lumen provides enhanced global illumination and Nanite enables increased graphical fidelity in the game (without excessive overhead).^[8]^[9]^[10]^[4]
- The recommended system specs for the game have not changed for Unreal Engine 5.^[11]^[12]

Nanite brings us really an entirely new approach to rendering and art workflows. Now we can render more actors with extremely high detail while eliminating the need to bake out normal map textures. For artists essentially what this means is that they can import high quality sculpted meshes directly into Unreal 5 without really having to reduce the poly count, making the workflow more efficient while simultaneously improving the quality of the art.^[13] – Steven Sharif

Lumen is going to greatly improve the visual fidelity and performance of the game with the reduced work and effort that's required by the art team, making Ashes of Creation much more beautiful than in UE4.^[8] – Steven Sharif

Unreal Engine 5 features (such as World partitions and One file per actor) make it much easier for multiple developers to work together.^[4]
- World partitions also enable Unreal Engine 5 maps to exceed the map size constraints of UE4 (~20 kilometers squared).^[4]

Q: How does this upgrade to UE5 affect the Ashes of Creation release timeline?^[4]

A: While UE4 is a great engine, there are certain focuses and technological endeavors that Epic is doing on UE5 that won't necessarily be supported by UE4; and we want to make sure given the lifespan of Ashes and how long we intend this MMO to last, that when we made this decision early on during the development process that we weren't going to exacerbate the amount of effort it would take to move over later in the lifespan or after launch.^[4] – Steven Sharif

Ashes of Creation features a custom Unreal Engine back-end with proprietary networking code to enable mass combat in the open world: such as PvP, Node-Belagerungen, Burgbelagerungen, Dungeon and Weltbosse.^[14]

The networking solution dynamically distributes processes and scales up necessary server instances to accommodate player density across the world.^[15]

Over October and November, that's when McP and the engineers began to do the base migration of our custom code-base into UE5 see where there were any major issues. The great thing about UE5 is that it's mainly focused around updating the renderer- giving access to Nanite, Lumen global illumination- those are big components. There's other great aspects of it, but really it's a front-end change and it doesn't affect our networking layer. It doesn't affect our back-end code.^[16] – Steven Sharif

The upgrade to Unreal Engine 5 is primarily a change to the front-end side of the game. The custom back-end networking code remains largely unaffected.^[16]
- As of January 24, 2022 all teams have moved over to Unreal Engine 5.^[17]
- The developers were able to transition to Unreal Engine 5.1.1 in February 2023 as part of milestone 4.^[18]^[19]^[20]
- The decision to upgrading to 5.2 will be considered based on the team's needs.^[21]
- At some point the developers intend to stop updating Unreal Engine until post-launch. This decision will be based on careful consideration of potential delays and other risks.^[22]

Q: What is your stance in regards to focusing on delivering an MVP versus continuously upgrading your tools and engine to deliver a better product with new tech, even if that results in delays or additional years of development like UE 5.2, maybe 5.3 etc?

A: Our technical teams, especially our network team, our ICS teams, our gameplay engineering teams, they convene and weigh when our next update should be on the engine side: What new technologies might bring benefit overall. My perspective on how we balance the need for integration of new technology versus the responsibility we have in a timely manner to provide testing sessions that get us closer to the launch date; that's a delicate balance. I would say generally our disposition is not to incorporate new technologies that yield some significant amount of delay on the development side. We very much take the perspective that we're capable of adjusting and/or integrating those new technologies post-milestone, post-launch if necessary. At some point we'll stop updating the Unreal Engine in development until launch. That point hasn't come yet, but of course the larger the project grows and on the more custom we make the engine for our back-end needs; and for whatever else merge conflicts can occur- those mergers can become big and painful; and the update process gets more painful. So to answer your question shortly, we have a team that evaluates what direction we need to take there; and at the top of my mind is always, let's not incorporate delays as a result of leveraging new technologies.^[22] – Steven Sharif

Performance

Performance optimization when rendering 1300 simulated actors utilizing merged materials and meshes in Unreal Engine 5 Nanite.^[23] This test was confirmed post-stream to be running on a RTX 3070.^[24]

What you're seeing here showcases the new modular appearance component which can combine any set of meshes and materials into a single mesh and single material at run-time. What you're looking at is over 1300 different entities, different actors. These are simulated players essentially. Previously you saw the example they were just standing still. There was no animation, there was no effects, there was no environment and it was a thousand. This is thirteen hundred playing animations, playing effects, plus the environment which is Nanite in this example. So what you're seeing is all of these players moving around and doing something and you're seeing the frame rate at about 30 on Clayton's rig.^[25] – Steven Sharif

Here you see that the FPS in the top right corner is like seven or eight on average, so not too good from a rendering perspective... So by merging now you can see that the same thousand players who are wearing the same armors as previously are actually having a 300 percent increase- 300 to 400 increase- in the performance of the of the FPS. So it went from 7 to about 21 on average and that is a significant optimization point that obviously this is just the beginning of the optimization efforts.^[26] – Steven Sharif

Ashes of Creation performance with 5,000 simulated players (pre-alpha).^[27]

Ashes of Creation was performing at 50-60 FPS on a 1080 Ti during early Alpha-1 testing.^[28]

Game settings allow players to fine tune performance to suit their preferences and hardware capabilities.^[29]^[30]^[31]

A "default player appearance" may be automatically applied during sieges or other large scale battles to improve client-side performance.^[32]^[33]^[31]

I think you guys will agree with me here that effects now are, as opposed to where they were in Alpha-1, we've taken into account what people's feedback were, although it was always the case we were going to address them; and we've implemented them in such a way where they're more conducive to large player battles.^[29] – Steven Sharif

Alpha system requirements

Alpha-1 stress testing, March 17, 2021.^[34]

Funny story; So yesterday as we are stress/density testing with our NDA testers, I accidentally summoned 5k bears around our few hundred players. But hey, it didn’t crash! Can you spot Lt. Toast here?^[34] – Steven Sharif

These are fully operational NPCs. They have behavior trees, they have AI blackboards; you know they are functioning as an NPC would; and to my surprise, to everyone's surprise actually, the server handled it quite well: 5000 entities all within a very dense area.^[35] – Steven Sharif

Landform tool

Landform tool demonstration.^[39]

It's exciting seeing our artists react to this tool's availability now as part of their workflow and replacing, as you guys described, that external sculpting software like Zbrush or or Maya and creating really high resolution geometry to break it down in this- making it usable essentially in the actual engine itself.^[39] – Steven Sharif

Landform is a tool developed by Intrepid Studios that enables in-engine sculpting and texture blending within Unreal Engine 5.^[39]

Charakter-Ersteller

Scars in the Alpha-2 character creator (first pass).^[40]

The cool thing about this character creator is that it's not just intended for your character. It has application with NPCs that you might hire.^[41] – Steven Sharif

We're gonna use similar tech for implementing things like Animal husbandry.^[42] – Zachary Mallet

Kaelar Alpha-2 character creation (first pass).^[43]

This tech is 100% created in-house at Intrepid and is not metahuman.^[44] – Steven Sharif

We'll be adding many, many more customization options to the character creator.^[45] – Cody Peterson

The character creator (or character customization system) allows players to define the look of their in-game characters, hired NPCs; and potentially creatures raised by the animal husbandry profession.^[41]^[46]

Erscheinungsbild des Charakters can be adjusted through a wide range of presets and sliders.^[41]^[46]^[47]
Character blending provides easy to use customization by morphing together two or more character presets.^[48]
Character sculpting allows detailed customization of every aspect of the body.^[49]

The Ashes of Creation character creator is 100% developed in-house by Intrepid Studios and is not MetaHuman.^[44]

Additional character creator features include.

There will be unlockable features for character customization.^[50]

You have that scar because you participated in this siege, or these many sieges; or you have this tattoo because of your of a cultural background, or because of a quest that was accomplished where you're able to get that.^[50] – Steven Sharif

The ability to save and potentially to share characters with other players.^[40]^[51]

The beauty of it is that you can save your character- and we already have some of those features available- and load them; and in the future we want people to be able to share those characters amongst each other.^[40] – Margaret Krohn

The ability to undo changes (Ctrl + Z) will be supported, including undoing changes that were made several edits earlier.^[52]^[53]
Choosing base idle animations of characters will be possible in future.^[54]
- Certain animations, such as blinking, will be present when they don't interfere with the customization process.^[55]
Adjusting the background scene and lighting is a planned feature.^[55]

There's going to be a lot of environmental controls that are offered to the character creator so that people can set it up their scene the way they want to grab screenshots or to grab recordings or whatever they want to do.^[56] – Steven Sharif

Asymmetry in terms of manipulating different components of the body or different body features such as hair, beard, and eyes.^[57]

Asymmetry is going to be functionality that's possible in manipulating either different components of the body or different features like hair. The beard we saw a little bit of that blending with highlights that you can do. Margaret talked a little bit about the eye asymmetry that you can include. Obviously those are going to exist within certain parameters that we want to define on a per-race basis, but it is something that we think is cool.^[57] – Steven Sharif

Body adornments, such as piercings will be possible within cultural limits.^[58]
The developers are considering whether to allow custom tattoos to be uploaded by users.^[59]

The aim is for the character creator to be on par if not much better than that of BDO.^[60]^[61]

Erscheinungsbild des Charakters

Facial adjustments in the Alpha-2 character creator (first pass).^[62]

There is a great variation that's going to be available from a character standpoint when creating your character, especially around the face. Whether it be the shape of the jawline, the cheeks, the ears, the nose, the lips. You know we want to provide a lot of options and an agency to the player to customize their character appearance.^[63] – Steven Sharif

Alpha-2 Py'rai female and male character models.^[64]

Erscheinungsbild des Charakters kann im character creator(CC)^[65] und über den Salons/Barbershops angepasst werden. ^[50]^[66]

Wir möchten, dass es viel Raum für die Menschen gibt, ihre eigene Identität zu manifestieren und Rollenspiele zu spielen, wie sie es vom Aussehen her wollen. Es wird Parameter geben, innerhalb derer du einen Charakter anpassen kannst. Wir wollen, dass die Kultur und die Identität der Rassen in einem Bereich existieren, der sie leicht von anderen Spielern und anderen Kulturen identifizierbar macht. Aus diesem Grund müssen wir ein Spektrum haben, in dem Sie existieren können. Es wird viele Haarvarianten und Tattoos geben, die du verwenden kannst. Du kannst mit den Skalen der Gesichtsstruktur, den Knochen, der Höhe, Breite und dem Körperfettanteil spielen. Du kannst Körperbehaarung an verschiedenen Körperteilen hinzufügen. Wenn du Haare an deinen Füßen haben möchtest, kannst du das einstellen.^[67] – Steven Sharif

Charactermodelle sind auf Realismus ausgerichtet. ^[68]
Ein Spieler wird einen generischen Charakter vor der Anpassung sehen.^[69]
Charakterdesigns werden Einflüsse aus einer Vielzahl von Kulturen haben, darunter europäische, afrikanische und asiatische.^[70]
Lolis wird es nicht im Spiel geben. ^[71]^[72]
Schieberegler und andere Steuerelemente wie Farbpaletten bieten Flexibilität bei der Anpassung, aber es gibt Einschränkungen basierend auf Rasse,Geschlecht und den künstlerischen Stilrichtlinien, an die sich die Entwickler halten. ^[73]^[74]^[71]^[75]^[76]

Es wird Beschränkungen für die Schieberegler geben, das war eine der großen Fragen, als die Arbeit am Charakterersteller begann: Wie viel Entscheidungsfreiheit wollt ihr zulassen, wie die Unterlippe in diesem seltsam deformierten Look ganz nach unten zu ziehen oder zu haben wie [eine] versetzte Wange, die nur asymmetrisch zur Seite des Gesichts ist." Es wird nicht die Fähigkeit oder Handlungsfähigkeit geben, diese Art von seltsamen Charakterdingen zu erschaffen. Ihr werdet jedoch die Möglichkeit haben, all diese Komponenten zu bewegen, zu verschieben, zu ändern, zu vergrößern und zu verringern, aber sie werden auf eine vernünftigere und präsentiertere Weise gehalten, in dem Sinne, dass ihr das Aussehen des Zwergs nicht ändern könnt , noch die Dünir- oder Niküan-Rennen, um meiner Meinung nach etwas zu erschaffen, das traditionell als Loli-Charakter angesehen wird.^[71] – Steven Sharif

Character sculpting

Sculpting in the Alpha-2 character creator (first pass).^[77]

Clayton and I tag-teamed on this one. We really wanted to give players that feeling that they were grabbing and pulling and sculpting their own character; especially with more minute details. I mean, it would have been easy to give character- players 100 sliders, but it feels better to have a much more tactile response, like clicking and dragging and pulling all these points around.^[78] – Zachary Mallet

Sculpting micro adjustments with the Alpha-2 character creator (first pass).^[49]

Zach mentioned how much variation we achieve through the customization features. A lot of that is achieved through what Steven is playing with right now: with these dots that are appearing; and the reason why those are dots instead of the little plates that you see highlighted on the character is because these are actually changing the shape of the character's features altogether. Plates are used for moving things around and it sort of maps exactly to your input; and that's why that pick map or the plates feel so nice. Then you can click on those dots and drag those around and actually change the shape of a feature altogether.^[49] – Clayton Stamper

Sculpting provides the ability to customize different segments of any part of the body in the character creator.^[77]

Plates are used for moving features around.^[49]
Dots are use to change the shape of the character's features altogether.^[49]

Examples:

Adjusting the length and proportions of limbs.^[77]^[79]
Sizes of calves and thighs.^[77]^[79]
Adjustments will allow a character to appear more feminine or masculine.^[80]

Character blending

Blending in the Alpha-2 character creator (first pass).^[48]

This is more of a large scale macro tool that you can select a couple of presets and then you can get certain features from one preset or different features from a another preset. So you place down your presets and then you can click and drag and morph between those different presets.^[48] – Zachary Mallet

Character blending allows the combination of two or more presets from the character creator. It allows users to click and drag to morph between the different presets to create customized characters without spending time adjusting each angle of every body part.^[48]
