Unreal Engine 5.3 Top 5 features

One of the latest versions of Unreal Engine is Unreal Engine 5.3, which was released as a preview in August 2023. Unreal Engine 5.3 brings many improvements to the core features of the engine, such as Lumen, Nanite, Path Tracing, Multi-process Cook, and Skeletal Editor. These features enable game developers to create more realistic, detailed, and immersive games with less time and effort.

In this article, we will explore the top 5 features of Unreal Engine 5.3 and how they can benefit your game development process. We will also show you how to use these features in Unreal Engine 5.3 and what are the options and settings available for each feature. By the end of this article, you will have a better understanding of what Unreal Engine 5.3 can do for you and your games. Let’s get started!

Lumen in Unreal Engine 5.3

One of the most impressive features of Unreal Engine 5.3 is Lumen, a fully dynamic global illumination system that enables realistic lighting and shadows in your games. Lumen allows you to create dynamic scenes with changing light sources, time of day, weather, and geometry without any baking or pre-computation. Lumen also supports advanced effects such as reflections, refractions, translucency, and subsurface scattering.

Lumen works seamlessly with Nanite, another feature of Unreal Engine 5.3 that we will discuss later. Nanite is a virtualized geometry system that allows you to import and render millions of polygons without any loss of quality or performance. Lumen and Nanite work together to create high-fidelity scenes with rich details and dynamic lighting.

To use Lumen in Unreal Engine 5.3, you need to enable it in the Project Settings under Rendering > Global Illumination Method > Lumen. You can also adjust the performance options for Lumen under Rendering > Lumen. You can choose between three modes: Performance, Balanced, and Quality. Performance mode prioritizes frame rate over visual quality, while Quality mode prioritizes visual quality over frame rate. Balanced mode is a compromise between the two. You can also tweak other settings such as Indirect Lighting Quality, Reflection Quality, Shadow Quality, and more.

Nanite

Another feature of Unreal Engine 5.3 that will blow your mind is Nanite, a virtualized geometry system that allows you to import and render millions of polygons without any loss of quality or performance. Nanite enables you to create highly detailed and complex scenes with unlimited geometric detail. Nanite also supports level-of-detail, occlusion culling, and streaming, so you don’t have to worry about optimizing your meshes or textures.

Nanite works hand in hand with Lumen, the global illumination system that we discussed earlier. Nanite and Lumen work together to create realistic lighting and shadows for your scenes. Nanite also supports other features of Unreal Engine 5.3, such as Path Tracing, Multi-process Cook, and Skeletal Editor.

To use Nanite in Unreal Engine 5.3, you need to enable it in the Project Settings under Rendering > Virtualized Geometry Method > Nanite. You can also adjust the optimization options for Nanite under Rendering > Nanite. You can choose between three modes: Performance, Balanced, and Quality. Performance mode prioritizes frame rate over visual quality, while Quality mode prioritizes visual quality over frame rate. Balanced mode is a compromise between the two. You can also tweak other settings such as Streaming Budget, Culling Quality, Clustering Quality, and more.

Path Tracing

Path Tracing is a feature of Unreal Engine 5.3 that simulates realistic light transport in your scenes. Path Tracing is a ray tracing technique that traces the paths of light rays from the camera to the light sources, accounting for multiple bounces, reflections, refractions, and scattering. Path Tracing can create cinematic quality images with accurate lighting, shadows, and colors.

Path Tracing works well with Lumen and Nanite, the features that we discussed before. Path Tracing can use the dynamic global illumination from Lumen and the unlimited geometric detail from Nanite to create stunning scenes with high-fidelity visuals. Path Tracing can also support other features of Unreal Engine 5.3, such as Sparse Volume Textures, Volumetric Path Tracing, and Orthographic Rendering.

To use Path Tracing in Unreal Engine 5.3, you need to enable it in the Project Settings under Rendering > Ray Tracing Method > Path Tracer. You can also adjust the quality options for Path Tracing under Rendering > Path Tracer. You can choose between three modes: Performance, Balanced, and Quality. Performance mode prioritizes frame rate over visual quality, while Quality mode prioritizes visual quality over frame rate. Balanced mode is a compromise between the two. You can also tweak other settings such as Samples Per Pixel, Max Bounces, Caustics, and more.

Multi-process Cook

Multi-process Cook is a feature of Unreal Engine 5.3 that reduces the build times of your games. Multi-process Cook is a cooking system that uses multiple processes to parallelize the cooking tasks, such as asset compression, shader compilation, and data packaging. Multi-process Cook can speed up the cooking process by using all the available CPU cores and memory on your machine.

Multi-process Cook works with Unreal Automation System, a framework that allows you to automate various tasks in Unreal Engine, such as testing, profiling, and deploying. Unreal Automation System can use Multi-process Cook to run multiple cooking jobs in parallel, either locally or remotely. Multi-process Cook can also support other features of Unreal Engine 5.3, such as Nanite, Path Tracing, and Skeletal Editor.

To use Multi-process Cook in Unreal Engine 5.3, you need to enable it in the Project Settings under Packaging > Build Configuration > Multi-Process Cook. You can also adjust the configuration options for Multi-process Cook under Packaging > Multi-Process Cook. You can choose between three modes: Single Process, Multiple Processes, and Multiple Processes with Server. Single Process mode uses only one process for cooking, while Multiple Processes mode uses multiple processes without a server. Multiple Processes with Server mode uses multiple processes with a server that coordinates the cooking tasks. You can also tweak other settings such as Max Concurrent Processes, Max Memory Usage, and more.

Skeletal Editor

Skeletal Editor is a feature of Unreal Engine 5.3 that enables you to do in-engine weight and skinning work for your skeletal meshes. Skeletal Editor is a tool that allows you to create and modify skeletons, assign bones, edit weights, and preview animations. Skeletal Editor can help you to create more realistic and expressive characters for your games.

Skeletal Editor works with Control Rig, a feature of Unreal Engine 5.3 that allows you to create procedural animation rigs for your characters. Control Rig is a node-based system that lets you define the logic and behavior of your rigs, such as IK, FK, constraints, and drivers. Control Rig can also work with Sequencer, the cinematic tool of Unreal Engine, to create dynamic and interactive cutscenes.

To use Skeletal Editor in Unreal Engine 5.3, you need to open it from the Content Browser by double-clicking on a skeletal mesh asset. You can also access it from the Viewport by selecting a skeletal mesh actor and clicking on the Edit button. You can then use the tabs and panels of Skeletal Editor to edit your skeleton, such as Skeleton Tree, Mesh Details, Viewport, and Animation Tools.

Conclusion

We have covered the top 5 features of Unreal Engine 5.3 and how they can benefit your game development process. Unreal Engine 5.3 is a powerful and versatile game engine that offers many improvements and enhancements to the core features of the engine, such as Lumen, Nanite, Path Tracing, Multi-process Cook, and Skeletal Editor. These features enable you to create more realistic, detailed, and immersive games with less time and effort.
