In the course of the State of Unreal keynote held at GDC 2024, Unreal Engine revealed some attention-grabbing new developments which are coming within the subsequent replace of its graphics engine. Builders will now have the ability to create genuine, extremely dense environments and character particulars in actual time in a manner that simply doesn’t appear to have been potential prior to now. The corporate demoed these new capabilities throughout an early preview of Marvel 1943: Rise of Hydra, and it’s actually fairly spectacular.
The demo exhibits us what UE can do now, all immediately transmitted with the assistance of a live-in editor and a digital digicam. Kim Liberi, chief expertise officer of Epic Video games, and Amy Henning from Skydance Media launched the viewers to a bridge atmosphere set in 1943. Initially, the scene was extremely detailed however then it was damaged right down to its naked bones to visualise simply how a lot is being added in real-time by the editor.
The brand new updates to Unreal Engine 5.4 enable sport devs to construct genuine environments with the assistance of what’s known as Nanite adaptive tessellation. The environments are constructed from the bottom up, including particulars corresponding to floor texture, snow, or smoke. The lighting is very spectacular, with components like smoke casting shadows on the bottom, but in addition on itself — and all of that is being added or eliminated in actual time.
“This system means that you can add an unprecedented degree of geometric element, however it’s additionally reminiscence environment friendly and could be modified dynamically within the runtime of your sport. Issues like footprints, tire tracks, and even supernatural results could be visualized,” stated Liberi, referring to a method known as Nanite. “It’s a very good, attention-grabbing approach to really get particulars into the sport with out loopy quantities of geometry.”
This expertise is helpful for every kind of particulars within the atmosphere, and never simply the bottom. The demo confirmed off one other new approach in Unreal Engine, referred to as heterogeneous volumes whereas zooming in on smoke pouring out of a barrel on fireplace within the scene.

This could have beforehand been achieved with particle sprites, however as Liberi famous, the ultimate impact can break down and look flat. “It’s good from afar, however removed from good,” he added.
Heterogeneous volumetrics forged shadows throughout the remainder of the scene, in addition to inside itself. This may also be combined with extra conventional strategies, corresponding to by including particles, and all of this may be achieved natively within the engine or by importing huge knowledge units. In talking concerning the sensible smoke and lighting within the scene, Liberi says the result’s “film-quality visible results, all operating in real-time which are completely conscious of dynamic lighting.”
The usage of AI in sport creation is slowly seeping into the very basis of gaming, beginning with issues like AI-driven dialogue powered by Nvidia, as much as AI-supported worlds like what we’re seeing right here in Unreal Engine. The ultimate result’s definitely spectacular and should assist smaller and greater sport studios create realistic-looking AAA titles.
There are tons extra particulars in Unreal Engine 5.4 for builders that have been mentioned, in addition to extra particulars to be realized. The primary preview for Unreal Engine 5.4 is about to be launched in late April.
