Shortly after the announcement of AMD partnering with Epic on UE5, NVIDIA countered with a similar blog post where we learned that much the same thing happened with the green team while the Unreal Engine 5 was under development.

　　Nick Penwarden, Vice President of Engineering at Epic Games, stated:

　　We’ve utilized RTX GPUs extensively throughout the development of Unreal Engine 5 and all of the respective sample content released today. Thanks to a tight integration with NVIDIA’s tools and technologies our team is able to more easily optimize and stabilize UE5 for everyone.

　　NVIDIA also went on to say it's working to enable a broad range of its technologies in the UE5, starting with Reflex, the latency lowering tech that is already available to anyone who's already diving into the early access version of Unreal Engine 5. Support for NVIDIA's Deep Learning Super Sampling (DLSS) image reconstruction technique is also said to be on the way 'in the coming weeks'.

　　The UE5 early access is available now. Epic is planning to exit early access at some point in early 2022. Below you'll find a recap of all the main features of Unreal Engine 5.

Nanite

　　Create games with massive amounts of geometric detail with Nanite, a virtualized micropolygon geometry system. Directly import film-quality source art comprised of millions of polygons—anything from ZBrush sculpts to photogrammetry scans—and place them millions of times, all while maintaining a real-time frame rate, and without any noticeable loss of fidelity.Nanite intelligently streams and processes only the detail you can perceive, largely removing  poly count and draw call constraints, and eliminating time-consuming work like baking details to normal maps and manually authoring LODs—freeing you up to concentrate on creativity. 

Lumen

　　Lumen is a fully dynamic global illumination solution that lets you create dynamic, believable scenes where indirect lighting adapts on the fly to changes to direct lighting or geometry—for example, changing the sun’s angle with the time of day, turning on a flashlight, or opening an exterior door.With Lumen, you no longer have to author lightmap UVs, wait for lightmaps to bake, or place reflection captures; you can simply create and edit lights inside the Unreal Editor and see the same final lighting as when the game is run on console.

Open worlds

　　One of our ongoing goals is to make the creation of open worlds faster, easier, and more collaborative for teams of all sizes. With UE5, a new World Partition system changes how levels are managed and streamed, automatically dividing the world into a grid and streaming the necessary cells.Team members can now also simultaneously work on the same region of the same World without treading on each other’s toes, thanks to a new One File Per Actor system, while with Data Layers, you can create different variations of the same World—such as daytime and nighttime versions—as layers that exist in the same space.

Animation

　　Author incredibly detailed characters in dynamic, real-time environments with UE5’s powerful animation toolset. Working in context, you can iterate faster and more accurately, without the need for time-consuming round-tripping.Artist-friendly tools like Control Rig let you quickly create rigs and share them across multiple characters; pose them in Sequencer and save and apply the poses with the new Pose Browser; and easily create natural movement with the new Full-Body IK solver. And with Motion Warping, you can dynamically adjust a character’s root motion to align to different targets with a single animation.

MetaSounds

　　With UE5, we’re introducing a fundamentally new way of making audio. MetaSounds is a high-performance system that offers complete control over audio DSP graph generation of sound sources, letting you manage all aspects of audio rendering to drive next-generation procedural audio experiences.MetaSounds is analogous to a fully programmable material and rendering pipeline, bringing all the benefits of procedural content creation to audio that the Material Editor brings to shaders: dynamic data-driven assets, the ability to map game parameters to sound playback, huge workflow improvements, and much more.

Editor workflow

　　In UE5, the Unreal Editor gets a makeover, with an updated visual style, streamlined workflows, and optimized use of screen real estate, making it easier, faster, and more pleasing to use.To free up more space for viewport interactions, we’ve added the ability to easily summon and stow the Content Browser and to dock any editor tab to the collapsible sidebar. You can now quickly access frequently used properties in the Details panel with a new favoriting system, while the new Create button on the main toolbar lets you easily place Actors into your world. There’s also a streamlined, easier workflow for creating new projects.
