Unreal Engine 5 is now available in Early Access. Epic Games announced on Wednesday that all developers can download its next-generation game engine for testing. The early access version of Unreal Engine 5 has most of its signature features, including the virtualized micro-polygon system Nanite, the global lighting module Lumen, and the World Partition system, which will allow game developers to create larger, more interconnected openness Before the world. Unreal Engine 5 supports PC, PS4, PS5, Xbox One, Xbox Series S/X, Nintendo Switch, Mac, iOS and Android. Of course, Epic Games will transition the “most popular game” Fortnite “offline” to Unreal Engine 5. It is expected that other titles will appear in the next few years.

The following is a complete list of the main features in Unreal Engine 5’s early access:


Our new Nanite virtual micro-polygon system allows users to create games with unprecedented amounts of geometric detail. Directly import movie-quality original assets composed of millions of polygons and place them millions of times while maintaining the real-time frame rate without any obvious loss of fidelity. Nanite intelligently processes and processes only the details you can perceive, which greatly eliminates polygon counting and drawing limits, and eliminates time-consuming tasks such as baking details into normal maps and manually creating LODs, thus enabling you Can focus on creativity.

Lumens is a fully dynamic global lighting solution that allows users to create dynamic, realistic scenes. With the help of lumens, indirect lighting can instantly adapt to direct lighting or geometric changes, such as changing the angle of the sun with the time of day, turning on a flashlight or opening an exterior door. This means you no longer need to write lightmap UVs, wait for lightmaps to bake or place reflection captures—you only need to create and edit lighting in the Unreal Editor and see the same final lighting as when running the game on the console That’s it.

Open world

One of our goals is to make teams of all sizes faster, easier, and more collaborative to create an open world. The new World Partition system in Unreal Engine 5 changes the level of management and streaming, dividing the world into grids and streaming the required cells. Team members can also work in the same area of ​​the same world at the same time through the new “one file per actor” system without stepping on each other’s toes. The data layer allows you to create different variants of the same world (such as day and night versions) as layers that exist in the same space.

Using Unreal Engine 5’s powerful animation toolset, you can create incredibly detailed characters in a dynamic real-time environment. Working in context, you can iterate faster and more accurately without the need for time-consuming round trips. Artist-friendly tools such as Rig allow you to quickly create rigs and share them among multiple characters. Place them in the Sequencer, then use the new “Pose Browser” to save and apply these poses; and use the new Full-Body IK solver to easily create natural movements. With “Motion Deformation”, you can dynamically adjust the root motion of the character to align it with different targets through a single animation.

Meta voice

Unreal Engine 5 introduces a new audio production method through the high-performance system MetaSounds, which can fully the audio DSP graphics generation of the sound source, enabling users to manage all aspects of audio rendering to drive the next generation of program audio Experience. MetaSounds is similar to a fully programmable material and rendering pipeline, bringing all the advantages of procedural content creation to the audio that the material editor brings to the shader: dynamic data-driven assets, the ability to map game parameters to sound playback, huge Workflow improvements, and more.

Editor workflow

The improved Unreal Editor provides updated visual styles, simplified workflow and optimized use of screen space, making it easier, faster and more to use. In order to free up more space for viewport interaction, we added the ability to easily summon and store the content browser and dock any editor tab in the collapsible sidebar. Now you can use the new favorites system to quickly access frequently used properties in the “Details” panel, and the new “Create” button on the main toolbar allows you to easily place Actors in your world.
