Making it in Unreal: how VR garage biotech comes to life in Seed

Seed Unreal Engine 4

Update 15 Feb, 2018: Seed has been chosen as the winner of the Developing Beyond award, a $500,000 year-long development competition created by Epic Games and Wellcome.

The theme of the award was 'transformations’, and as the winning game Seed will receive a development grant of $150,000. Mike Gamble, European Territory Manager at Epic, said, “The jury was unanimous in voting for Seed as the deserved winner of this year’s Developing Beyond. All Seeing Eye have created a beautiful place to explore and spend time in, as well as delivering great gameplay and hitting all the scientific beats on right on the mark.”

Original story: In 2017, gene splicing is something that happens in front of a computer. But in the ‘40s and ‘50s, before the dawn of modern science, garage biotech was on the rise. Just as some hobbyists fiddled with radios and rockets, others were biohacking in the comfort of their own homes, combining plants to create new strains.

“Back then,” Seed creative lead Olie Kay tells us, “it was a lot more trial and error and a lot simpler.”

Ideal, really, for a game. Seed is on its way to being just that - a game that turns the real-world art of plant-splicing into a calming and curious procedural puzzler in VR.

“There are huge titles like No Man’s Sky that contain vast procedural systems, but they’re not as focused,” Kay says. “Ours incorporates the ability to really interrogate why the plant is growing the way it is by mixing things together and seeing what takes hold.”

You start with a handful of seeds and a machine called the ‘hybridiser’. The hybridiser is a kind of genetic microwave that simulates splicing, cross-pollination, and genetic engineering - the dextrous arts of plant-mixing that “don’t play well in VR.” The system that defines how those plants mix, however, comes straight out a textbook. Literally.

Working in Unreal Engine 4, Seed developers All Seeing Eye are using the L-systems first developed to model the growth processes of plants in 1968.

“You get an equation which is about how many branches a plant has, and that’s a system we’ve piggybacked onto,” Kay explains. “You can look at an old textbook that has all these equations, and input that string into Unreal. You’ll get a plant out that looks like the one that’s been drawn in the textbook 60 years ago.”

Seed plants

The plants in Seed grow in fast-forward, glowing and graceful. This is a fanciful, idealised visualisation of a process that would in reality take days, weeks, and months. Yet this is precisely where that real-world procedural system kicks in.

Rather than building a 3D model of a sunflower in Maya and spawn it into the world, All Seeing Eye have built a list of hundreds of attributes that define the way their plants look. Depending on their makeup, plants will grow leaves of different shapes and sizes, and stems of varying widths. The systems take factors like curvature and colour into account, too.

“We know what those first few seeds are going to look like, but one or two generations down the road we have no idea,” Kay says. “All of that is dynamic and kind of fascinating.”

Seed is being created for Developing Beyond, a game dev competition hosted by Epic Games and Wellcome, in which a number of prototypes have so far been awarded funding. All Seeing Eye hope to succeed in the next round of judging in January, after which they have plans for fruit, vegetables, and flowers.

“All of those are separate systems that we’re looking to add, ensuring that they remain completely procedural and complex,” Kay says.

Seed HTC Vive

All Seeing Eye have developed Seed for the HTC Vive. Players interact with their garage by reaching out and pressing the trigger on the hand controller to pick up a seed - and releasing to drop it again. The team are taking a diegetic approach: that is, ensuring that every sight and sound in Seed has an obvious and sensible source on-screen. 

“All the audio you hear in the game is from the world, and we’re trying to be very minimal about in-world UI,” Kay says. “Panels of UI that float around work fine in a science fiction setting, but when we’re working with this analogue history and aesthetic, that feels quite jarring.”

In fact, everything about Seed, from its playful, homegrown science to its stripped-back VR, suggests a simplicity verging on the zen.

Seed UE4 game

“People always comment on how much they enjoy being in the environment, and how it feels like a nice place to exist,” Kay concludes. “You should be able to pick up the game, smash stuff together and make it work. It feels like we’re just scratching the surface.”
