The quality of the dynamic lighting is one of the most impressive elements of the Infiltrator demo, but it's not as much of a performance hot-spot as you may imagine.
"The dynamic lights are not our current performance limit. Our limits come more from the amounts of massive overlapping shadow-casting lights," Willard said. "That's not been a huge challenge because typically we don't need that many to get a perfect-looking scene."
Willard confirmed that Infiltrator was running in real-time on the PC hardware by adjusting layers and lighting as the demo played out. He also cited elements of the demo that would have been far more difficult - or even impossible - without the new workflow Unreal Engine 4 offers.
"One thing to note - as the protoganist comes up to the city and we have a nice wide shot of the vista, that's actually built out geometrically all the way out to the horizon line rather than having the equivalent of a matte painting as you'd see in a movie," he explained. "We actually built that entire cityscape out, including the mountains. The only things that aren't are the clouds that are embedded into the city. Everything else is full geometry from foreground to background."
