So, the new surprise that Fortnite has in store for us with the launch of the new Chapter 4 is the official transition to Unreal Engine 5.

With the launch of the events of the first season of Chapter 4, which is now available to everyone, the game uses all the new technologies of Unreal Engine 5.1.

Unreal Engine 5 Technologies in Fortnite

1. Nanite's new stereoscopic technology.
2. Lumen new lighting technology.
3. Virtual Shadow Maps Technology.
4. Super temporal resolution technology.

Nanite Technology in Fortnite

Nanite’s new digital construction technology delivers highly detailed architecture. Specifically, buildings are rendered from millions of polygons in real time, and every brick, stone, slat, and wall decoration is modeled.

In addition, the landscapes also feature high-definition details. A single tree contains about 300,000 polygons, and each stone and flower of grass is designed separately.

What about the new Lumen technology?

Lumen reflections provide high-quality rays reflected off shiny surfaces and water. This technology provides real-time global illumination while maintaining a rendering rate of 60 frames per second.

You’ll see beautiful interiors with light reflecting off surfaces, as well as characters interacting with the light around them. For example, red carpets can reflect red light onto their persona. Additionally, clothing with emissive qualities, such as shiny clothing, reflects light onto nearby objects and surfaces.

Virtual Shadow Maps Technology.

Virtual Shadow Maps technology will render highly detailed shadows for all objects. Every brick, leaf, shadow will be reflected in a very realistic way. Also the character's self-shadowing, which will be very subtle. This means that things like hats and other small details on the characters will also reflect their shadows.

Say hello to TSR technology in Fortnite

Temporal Super Resolution is an alternative to Temporal Anti-Aliasing technology that will be present in the Fortnite game, and allows you to display various figures and drawings with high resolution quality and high frame rate.

Of course, you’ll notice the quality of the game with the power of Unreal Engine 5 on the next-gen platforms, PlayStation 5 and Xbox Series, as well as on PC. But even on older platforms, the capabilities of the new engine will be explored.
