Blackbird Interactive Une étude de cas sur Unity

How do you create heart-pumping excitement in a sci-fi game where there are no aliens or enemies? By remembering that in cold, dark space, the entire environment is the antagonist. In Hardspace: Shipbreaker you’re salvaging junk spacecraft to pay off your debt to Lynx Corporation. But watch out – there’s a good chance you’ll set off an explosion and have to respawn, increasing your debt. To bring this futuristic and suspenseful game full of highly detailed, immersive visuals to life, Blackbird Interactive (BBI) chose Unity.

From the game’s conception, the studio wanted Hardspace: Shipbreaker to awe players with its high-fidelity vision of life in space. The game also had to feature physically accurate, zero-gravity object behaviors and collisions.

This presented significant challenges such as creating baked-quality artwork for completely dynamic environments, making processes integrated and efficient, and constantly finding better ways to develop and collaborate. Since the project start over four years ago, the BBI team has blasted through numerous technical barriers, innovated countless artistic techniques, and shared many “oh wow” moments on their way to delivering one of the most exciting space games in eons.

From the start, the BBI team wanted players – called “Cutters” – to fully feel the challenges and loneliness of space, under pressure to build the skills necessary to succeed against tough odds. But this is not a superhero game. As players move and work within the rich visual environment, they each create their own story.

“That’s a big part of the immersive experience for us,” says Trey Smith, Hardspace: Shipbreaker’s Game Director. “You play as yourself and become part of the story. For example, we designed the hands so they feel like they’re your hands and not some random bot hands. Highly realistic animation and effects were crucial too, as they ground you in the gameplay, making you more invested in what’s going on.”

The result is one of the most dynamic, rich gameplay environments imaginable. As players maneuver and cut, electricity sparks and fire erupts in the highly charged settings. There are realistic tools to manipulate, signs to read, tethers to attach, tight spaces to navigate, deep shadows and flying particles to adjust to, and much more. All in a zero-gravity, topsy-turvy environment. And because each player’s journey is unique, great individual stories unfold.

Putting this heightened drama together hinges on deeply realized visuals, and the studio was up for the challenge because, at its heart, it’s visually driven. “Our founders are all art directors and space geeks, yet we also know that gameplay is king. So we want people to be both drawn into our unique, painterly environment and play within it,” according to Art Director Chris Williams. “And Unity helps us combine those two key elements seamlessly.”

Virtually everyone on the team had worked with Unity according to Hardspace: Shipbreaker’s Tech Director Richard Harrison, “It’s a triple-A engine, but Unity also caters to developers who want to get something off the ground and reach that proof of concept really quickly.” This was especially important considering the small size of the team when the game was born (during an internal game jam) and the need to solve some substantial artistic challenges.

BBI leverages ProBuilder to determine how to properly manipulate, test, and craft the plethora of ships and other 3D models. “ProBuilder enables our designers to prototype ship layouts and gameplay props. Since object dimensions and other metrics are extremely important in our game, it lets us quickly iterate on rough blockouts to nail down an object size before asking Art for the final mesh,” says Elliot Hudson, BBI’s Associate Creative Director. “It really helps our artists build an efficient grey-box pipeline.”

To create many of the highly detailed and realistic animations, BBI used Timeline. For example, when a player begins their workday, Timeline is behind the power-up of all the lights in the hangar bay and the fire-up of the ship’s power source. “The first time our animator used Timeline, he loved it and immediately saw the potential for enhancing the realism of the game with cool details like that,” says Harrison.

They also used Cinemachine’s advanced camera tools for important design stages. “Our developers were able to quickly create proof-of-concept segments with Cinemachine that captured the vibe and tone of what we were trying to do. Being able to scrub a timeline and see the camera in the view was particularly useful,” says Trey Smith, BBI’s game director.

Améliorer leurs propres outils

Over the course of the project, BBI also built a set of Unity-friendly tools. Much of their core shader technology, for example, was hand-coded for the game, but the developers anticipate greater use of Shader Graph to take advantage of Unity’s High Definition Render Pipeline (HDRP) capabilities.

“We used to re-UV the entire ship but then we started leveraging more things like property blocks that allow us to dynamically change properties on materials on the fly. Beyond that, we use a cleverly put-together shader in Unity that uses the HDRP back end. Karl Kent, our art tech wizard, created it to go hand-in-hand with the HDRP tech,” says Harrison.

BBI’s projection tool piggybacks on several aspects of Unity, including HDRP, to increase dynamism when they paint the ships at runtime. They also use a custom projection decal system to produce cool warnings in the ships, such as Danger signs on the bulkheads, for even more suspense.

According to Harrison, the ships don’t have a lot of animation, just a few here and there, such as the handles you use to open the doors and the doors themselves. “A lot of the animations that we do are baked into texture animations, things that you see as you work, such as the lights on the computer screens. The MaterialPropertyBlock, which lets us modify things in real-time, has been super helpful.”

The most complex physical animation they tackled was for the one-and-only character: the Cutter. “We had our animator rig up the character and animate the whole thing dynamically through Mecanim. It’s entirely state driven and parameter driven. It takes into consideration player velocity – where you’re moving, and how you’re drifting.”

Of course, it’s a first-person game, so players can only really see their hands and legs, as well as reflections and shadows from time to time. “It’s a pretty powerful moment the first time you notice that when you drift off to the left, your legs lag behind you to the right. We feel that adds a sense of weight and presence to your character – helps you “feel” you’re in a zero-g environment,” adds Harrison.

Since many of the game’s 3D elements are created outside Unity, quick round-tripping to and from 3D modeling software, such as Maya, was particularly important to simplify and speed up repetitive processes. Williams says, “In some non-Unity environments, converting an FBX model could take half a day, but in Unity it’s almost instantaneous.” BBI built a custom editor, integrated within the Unity workflow, that lets their artists right-click on an asset and immediately turn it into a GameObject.

Another feature that significantly increased artist productivity was nested Prefabs. It lets them build a ship as a Prefab, made up of many smaller Prefabs, which in turn comprise multiple smaller Prefabs, so when they want to change a characteristic, they only need to make the modification once and it’s reflected throughout the model. In terms of workflow, this lets their artists get “under the hood” and assemble components on their own without having to code anything or rely on a programmer. According to Williams, “We were finally able to make a modular ship system with this handy feature. We wouldn’t be where we are today without nested Prefabs.”

In terms of always being in sync with the latest versions of Unity features, the team relies on regular updates via Package Manager. “We use a lot of integrated packages so it’s great to be able to sync when there’s a new version that might have an enhancement or bug fix we’ve been waiting for. The Package Manager has been an important enhancement to our workflow,” says Harrison.

supercharge the entire game, it’s not surprising that BBI tapped David Perdigon, their highly talented visual-effects artist, to create and control them. And when Visual Effect Graph (VFX Graph) became available, they adopted it immediately, finding it easy to use and tweak, and appreciate that it can handle far more digital input compared to legacy tools such as Flipbook or the Shuriken Particle System.

While it’s exciting to add eye-catching pyrotechnics into a game, they almost always cause performance tradeoffs, which was a dealbreaker for the studio. However, when they implemented particles with VFX Graph, BBI found they could efficiently manage greater numbers of particles and include more stunning effects, more often.

This is largely because VFX Graph smoothly integrates particles into the Post Processing Stack and lighting. “There was a big performance increase when we made the switch to VFX Graph, and now particles feel like they’re actually integrated into the world rather than being beside the geometry,” says Harrison. They also tap Bloom and other Unity color-balancing tools to ratchet up the game’s visual wow factor.

A key to producing believable and gorgeous light and shadows in space was the High Definition Render Pipeline (HDRP). For example, a hangar-bay scene might have four or five shadow-casting lights, and the developers needed to balance and align that bounce light with moving, directional sound. “With HDRP, everything is so responsive, and it was easy to understand right out of the box,” says Williams.

HDRP also helped them create highly convincing area lighting in the abandoned-ship interiors, adding to the tension. For example, the team used volumetric lighting to create a “dirty air” effect when a Cutter pressurizes a ship, creating fog and drifting particulates. This makes a headlamp beam as vivid as a searchlight in the night sky. Pre-HDRP, BBI had tried using third-party tools to mimic these kinds of volumetric effects, but found them expensive and limiting. According to Williams, “The power of Unity’s HDRP is that it’s a systematic approach to the entire lighting model itself, and it beautifully suits our needs.”

At BBI, they choose their game-development platforms carefully, asking themselves what tech and tools are best suited for the project, and then they do comprehensive technical, design, and art assessments. “I think it speaks volumes that we chose Unity for Hardspace: Shipbreaker right after we completed our first game – Homeworld: Deserts of Kharak. And now that Hardspace is live, we can definitely say that our initial assessments were correct – Unity was absolutely the right choice to meet our artistic, technical, and business needs,” concludes Harrison. Suffice it to say, they’re busy driving Unity to the max to craft new features and game content for the full release – and the results are sure to please the legion of Cutters writing their own stories in this beautifully realized “blue-collar” game.

"Nos fondateurs sont tous des directeurs artistiques et des passionnés d'espace, mais nous savons aussi que le jeu est roi. Nous voulons donc que les gens soient à la fois attirés par notre environnement unique et pictural et qu'ils s'y amusent. Unity nous aide à combiner ces deux éléments clés de manière transparente".
"Je pense que le fait que nous ayons choisi Unity pour Hardspace en dit long : Shipbreaker juste après avoir terminé notre premier jeu - Homeworld : Déserts de Kharak. Et maintenant que Hardspace est en ligne, nous pouvons affirmer que nos évaluations initiales étaient correctes - Unity était absolument le bon choix pour répondre à nos besoins artistiques, techniques et commerciaux. C'est un moteur triple A, mais Unity s'adresse aussi aux développeurs qui veulent faire démarrer quelque chose et obtenir une preuve de concept très rapidement". 
"ProBuilder permet à nos concepteurs de créer des prototypes de vaisseaux et d'accessoires de jeu. Les dimensions des objets et d'autres paramètres étant extrêmement importants dans notre jeu, cela nous permet d'itérer rapidement sur des blocs approximatifs pour fixer la taille d'un objet avant de demander à Art de nous fournir le maillage final. Il aide vraiment nos artistes à construire un pipeline efficace de boîtes grises".
"Nos développeurs ont pu rapidement créer des segments de démonstration avec Cinemachine qui capturaient l'ambiance et le ton de ce que nous essayions de faire. La possibilité de scruter une ligne de temps et de voir la caméra dans la vue a été particulièrement utile".
