Who would volunteer to make a flight simulator? They are an inconceivable ask: extremely detailed but enormously huge. It is an issue that solely will get harder as manufacturing values improve in keeping with new hardware, pushing expectations for graphical constancy to new heights. Yet developer Abi Rahmani has thrown himself into Project Wingman, a flight sport that goals to make accessible however nonetheless genuine pilotry a actuality in Unreal Engine four.

Inside the cockpit
While flight video games allow us to see the world from above – or, a minimum of, an honest approximation of it – additionally they largely happen in a single atmosphere: the cockpit.
“I definitely look at references from different games, video footage of cockpits, and what it feels like to fly when I’m travelling myself,” Rahmani tells us. “Of course, it’s not the real jet, but it should somewhat deliver the same feeling.”
That feeling, particularly, is the sense of complicated and thrilling equipment specified by entrance of you. Wingman’s cockpit is not going to be absolutely interactive, however it should current you with an enormous array of buttons and neon-green screens that evoke a chocolate field of cutting-edge expertise.
“Unreal Engine’s lighting system definitely helps that,” Rahmani says.
The tools isn’t all for present – a few of it relays essential data to you throughout flight, pulling background numbers from the engine and presenting them as they’d be inside an actual aircraft. “The main thing reflecting back to the player is altitude and speed,” Rahmani explains, “which mostly the engine already provides.”
It is one factor to be advised that you’re travelling very quick, although, and fairly one other to really feel it. Measurements alone can’t convey a way of pace, particularly when adrift from the factors of reference you might need on the bottom. In this regard, Project Wingman’s finest trick is the rain that runs throughout the cockpit home windows throughout storms – really a water-on-canopy impact enabled by Unreal Engine four’s refraction shaders.
“It’s not necessarily realistic, but it does provide that spectacle that makes you convinced you’re in a rainy area,” Rahmani says. “It’s a lot of masks and texture work, really, and panning materials.”
Elsewhere, Rahmani has taken a real-world impact and given it an exaggerated sport design perform.
“One thing I’ve recently added is a deep rumbling sound when you’re close to the ground, just to let you know,” he says. “It’s more emphasised, so it’s not as quiet as it would be in real-life. It’s a subtle effect, but it can give you the sense you’re about to crash, especially if you’re visually blocked by rain or clouds.”
A bit of landscaping
Before tackling the nice panorama under the aircraft, Rahmani watched a DICE discuss through which a designer defined how the studio went about constructing maps for the Battlefield video games. That method has been expanded to a a lot bigger space of geography for Project Wingman.
“I used World Machine and essentially scaled it up to what we needed,” he says.
World Machine is a strong instrument for creating 3D terrain with real looking geological results. Handily sufficient, it offers peak maps that may be enter straight into Unreal Engine four.
“Basically, we use World Machine to add erosion data, rivers, and shape the landscape the way we want it,” Rahmani explains.
Even with the heavy lifting dealt with by a specialised piece of software program, it feels like a hefty atmosphere for a sport to run – particularly when flying overhead at pace. But, fortunately, the engine additionally has an automatic LOD generation system, which works to dramatically scale back the polygon rely of objects on this planet with a minimal of visible influence.
“That makes it really easy for us to do large landscapes without performance drawbacks,” Rahmani says. “I’ve never necessarily seen very detailed trees in flight simulators, and that’s one thing I’ve added, to just make the landscape look more convincing when you fly across forests and mountainous areas.”
Rahmani has outsourced music to a composer in London, and has the assist of a handful of volunteers in sourcing and recording voices for the sport. But for probably the most half he’s flying solo, which makes this marriage of granular element and sweeping topography all of the extra outstanding.
You can observe the development of Project Wingman on itch.io. Unreal Engine 4 is now free.
